- - - - @section page_port_wxgtk wxGTK - - @htmlonly - - @endhtmlonly - - wxGTK is a port of wxWidgets using the GTK+ library. - It makes use of GTK+'s native widgets wherever possible and uses - wxWidgets' generic controls when needed. GTK+ itself has been - ported to a number of systems, but so far only the original X11 - version is supported. Support for other GTK+ backends is planned, - such as the new DirectFB backend. - - All work is being done on GTK+ version 2.0 and above. Support for - GTK+ 1.2 will be deprecated in a later release. - - You will need GTK+ 2.0 or higher which is available from: - - http://www.gtk.org - - The newer version of GTK+ you use, the more native widgets and - features will be utilized. We have gone to a great extent to - allow compiling wxWidgets applications with a latest version of - GTK+, with the resulting binary working on systems even with a - much lower version of GTK+. You will have to ensure that the - application is launched with lazy symbol binding for that. - - In order to configure wxWidgets to compile wxGTK you will - need use the @c --with-gtk argument to the @c configure script. - This is the default for many systems. - - GTK+ 1.2 can still be used, albeit discouraged. For that you can - pass @c --with-gtk=1 to the @c configure script. - - For further information, please see the files in docs/gtk - in the distribution. - - - - - @section page_port_wxmac wxMac - - @htmlonly - - @endhtmlonly - - wxMac is a port of wxWidgets for the Macintosh OS platform. - Currently MacOS 8.6 or higher, MacOS 9.0 or higher and - MacOS X 10.0 or higher are supported, although most development - effort goes into MacOS X support. wxMac can be compiled both - using Apple's developer tools and MetroWerks CodeWarrior in - different versions. Support for MacOS 8.X and MacOS 9.X is - only available through CodeWarrior. wxMac uses the Carbon - API (and optionally the Classic API under MacOS 8.X). You - will need wxWidgets version 2.3.3 or higher for a stable - version of wxMac. - - For further information, please see the files in docs/mac - in the distribution. - - - - - @section page_port_wxmgl wxMGL - - wxMGL is a port of wxWidgets using the MGL library available - from SciTech as the underlying graphics backend. wxMGL draws - its widgets using the wxUniversal widget set which is now - part of wxWidgets. MGL itself runs on a variety of platforms - including DOS, Linux hardware (similar to the Linux framebuffer) - and various graphics systems such as Win32, X11 and OS/2. - Note that currently MGL for Linux runs only on x86-based systems. - - You will need wxWidgets 2.3.3 or higher and MGL 5.0 or higher. - The latter is available from - - http://www.scitechsoft.com/products/product_download.html - - In order to configure wxWidgets to compile wxMGL you will - need to type: - - @verbatim configure --with-mgl --with-universal @endverbatim - - Under DOS, wxMGL uses a dmake based make system. - - For further information, please see the files in docs/mgl - in the distribution. - - - - @section page_port_wxos2 wxOS2 - - wxOS2 is a port of wxWidgets for the IBM OS/2 Warp3 and Warp4 platforms. - This port is currently under construction and in beta phase. - - For more info about OS2 see: - - - - - @section page_port_wxx11 wxX11 - - @htmlonly - - @endhtmlonly - - wxX11 is a port of wxWidgets using X11 (The X Window System) - as the underlying graphics backend. wxX11 draws its widgets - using the wxUniversal widget set which is now part of wxWidgets. - wxX11 is well-suited for a number of special applications such - as those running on systems with few resources (PDAs) or for - applications which need to use a special themed look. You will need - wxWidgets 2.3.2 or higher. - - In order to configure wxWidgets to compile wxX11 you will - need to type: - - @verbatim configure --with-x11 --with-universal @endverbatim - - For further information, please see the files in docs/x11 - in the distribution. There is also a page on the use of - wxWidgets for embedded applications on the wxWidgets web site. - - - - - - @section page_port_wxmsw wxMSW - - @htmlonly - - @endhtmlonly - - wxMSW is a port of wxWidgets for the Windows platforms - including Windows 95, 98, ME, 2000, NT, XP in ANSI and - Unicode mode (for Windows 95 through the MSLU extension - library). wxMSW ensures native look and feel for XP - as well when using wxWidgets version 2.3.3 or higher. - wxMSW can be compile with a great variety of compilers - including MS VC++, Borland 5.5, MinGW32, Cygwin and - Watcom as well as cross-compilation with a Linux hosted - MinGW32 tool chain. - - For further information, please see the files in docs/msw - in the distribution. - - @subsection page_port_wxmsw_themedborders Themed borders on Windows - - Starting with wxWidgets 2.8.5, you can specify the wxBORDER_THEME style to have wxWidgets - use a themed border. Using the default XP theme, this is a thin 1-pixel blue border, - with an extra 1-pixel border in the window client background colour (usually white) to - separate the client area's scrollbars from the border. - - If you don't specify a border style for a wxTextCtrl in rich edit mode, wxWidgets now gives - the control themed borders automatically, where previously they would take the Windows 95-style - sunken border. Other native controls such as wxTextCtrl in non-rich edit mode, and wxComboBox, - already paint themed borders where appropriate. To use themed borders on other windows, such - as wxPanel, pass the wxBORDER_THEME style, or (apart from wxPanel) pass no border style. - - In general, specifying wxBORDER_THEME will cause a border of some kind to be used, chosen by the platform - and control class. To leave the border decision entirely to wxWidgets, pass wxBORDER_DEFAULT. - This is not to be confused with specifying wxBORDER_NONE, which says that there should - definitely be @e no border. - - @subsubsection page_port_wxmsw_themedborders_details More detail on border implementation - - The way that wxMSW decides whether to apply a themed border is as follows. - The theming code calls wxWindow::GetBorder() to obtain a border. If no border style has been - passed to the window constructor, GetBorder() calls GetDefaultBorder() for this window. - If wxBORDER_THEME was passed to the window constructor, GetBorder() calls GetDefaultBorderForControl(). - - The implementation of wxWindow::GetDefaultBorder() on wxMSW calls wxWindow::CanApplyThemeBorder() - which is a virtual function that tells wxWidgets whether a control can have a theme - applied explicitly (some native controls already paint a theme in which case we should not - apply it ourselves). Note that wxPanel is an exception to this rule because in many cases - we wish to create a window with no border (for example, notebook pages). So wxPanel - overrides GetDefaultBorder() in order to call the generic wxWindowBase::GetDefaultBorder(), - returning wxBORDER_NONE. - - @subsection page_port_wxmsw_wince wxWinCE - - wxWinCE is the name given to wxMSW when compiled on Windows CE devices; - most of wxMSW is common to Win32 and Windows CE but there are - some simplifications, enhancements, and differences in - behaviour. - - For building instructions, see docs/msw/wince in the - distribution, also the section about Visual Studio 2005 project - files below. The rest of this section documents issues you - need to be aware of when programming for Windows CE devices. - - @subsubsection page_port_wxmsw_wince_ General issues for wxWinCE programming - - Mobile applications generally have fewer features and - simpler user interfaces. Simply omit whole sizers, static - lines and controls in your dialogs, and use comboboxes instead - of listboxes where appropriate. You also need to reduce - the amount of spacing used by sizers, for which you can - use a macro such as this: - - @verbatim - #if defined(__WXWINCE__) - #define wxLARGESMALL(large,small) small - #else - #define wxLARGESMALL(large,small) large - #endif - - // Usage - topsizer->Add( CreateTextSizer( message ), 0, wxALL, wxLARGESMALL(10,0) ); - @endverbatim - - There is only ever one instance of a Windows CE application running, - and wxWidgets will take care of showing the current instance and - shutting down the second instance if necessary. - - You can test the return value of wxSystemSettings::GetScreenType() - for a qualitative assessment of what kind of display is available, - or use wxGetDisplaySize() if you need more information. - - You can also use wxGetOsVersion to test for a version of Windows CE at - run-time (see the next section). However, because different builds - are currently required to target different kinds of device, these - values are hard-wired according to the build, and you cannot - dynamically adapt the same executable for different major Windows CE - platforms. This would require a different approach to the way - wxWidgets adapts its behaviour (such as for menubars) to suit the - style of device. - - See the "Life!" example (demos/life) for an example of - an application that has been tailored for PocketPC and Smartphone use. - - @note don't forget to have this line in your .rc file, as for - desktop Windows applications: - - @verbatim #include "wx/msw/wx.rc" @endverbatim - - @subsubsection page_port_wxmsw_wince_sdk Testing for WinCE SDKs - - Use these preprocessor symbols to test for the different types of device or SDK: - - @li @b __SMARTPHONE__ Generic mobile devices with phone buttons and a small display - @li @b __PDA__ Generic mobile devices with no phone - @li @b __HANDHELDPC__ Generic mobile device with a keyboard - @li @b __WXWINCE__ Microsoft-powered Windows CE devices, whether PocketPC, Smartphone or Standard SDK - @li @b WIN32_PLATFORM_WFSP Microsoft-powered smartphone - @li @b __POCKETPC__ Microsoft-powered PocketPC devices with touch-screen - @li @b __WINCE_STANDARDSDK__ Microsoft-powered Windows CE devices, for generic Windows CE applications - @li @b __WINCE_NET__ Microsoft-powered Windows CE .NET devices (_WIN32_WCE is 400 or greater) - - wxGetOsVersion will return these values: - - @li @b wxWINDOWS_POCKETPC The application is running under PocketPC. - @li @b wxWINDOWS_SMARTPHONE The application is running under Smartphone. - @li @b wxWINDOWS_CE The application is running under Windows CE (built with the Standard SDK). - - - @subsubsection page_port_wxmsw_wince_sizing Window sizing in wxWinCE - - Top level windows (dialogs, frames) are created always full-screen. Fit() of sizers will not rescale top - level windows but instead will scale window content. - - If the screen orientation changes, the windows will automatically be resized - so no further action needs to be taken (unless you want to change the layout - according to the orientation, which you could detect in idle time, for example). - When input panel (SIP) is shown, top level windows (frames and dialogs) resize - accordingly (see wxTopLevelWindow::HandleSettingChange). - - @subsubsection page_port_wxmsw_wince_toplevel Closing top-level windows in wxWinCE - - You won't get a wxCloseEvent when the user clicks on the X in the titlebar - on Smartphone and PocketPC; the window is simply hidden instead. However the system may send the - event to force the application to close down. - - @subsubsection page_port_wxmsw_wince_hibernation Hibernation in wxWinCE - - Smartphone and PocketPC will send a wxEVT_HIBERNATE to the application object in low - memory conditions. Your application should release memory and close dialogs, - and wake up again when the next wxEVT_ACTIVATE or wxEVT_ACTIVATE_APP message is received. - (wxEVT_ACTIVATE_APP is generated whenever a wxEVT_ACTIVATE event is received - in Smartphone and PocketPC, since these platforms do not support WM_ACTIVATEAPP.) - - @subsubsection page_port_wxmsw_wince_hwbutt Hardware buttons in wxWinCE - - Special hardware buttons are sent to a window via the wxEVT_HOTKEY event - under Smartphone and PocketPC. You should first register each required button with - wxWindow::RegisterHotKey, and unregister the button when you're done with it. For example: - - @verbatim - win->RegisterHotKey(0, wxMOD_WIN, WXK_SPECIAL1); - win->UnregisterHotKey(0); - @endverbatim - - You may have to register the buttons in a wxEVT_ACTIVATE event handler - since other applications will grab the buttons. - - There is currently no method of finding out the names of the special - buttons or how many there are. - - @subsubsection page_port_wxmsw_wince_dialogs Dialogs in wxWinCE - - PocketPC dialogs have an OK button on the caption, and so you should generally - not repeat an OK button on the dialog. You can add a Cancel button if necessary, but some dialogs - simply don't offer you the choice (the guidelines recommend you offer an Undo facility - to make up for it). When the user clicks on the OK button, your dialog will receive - a wxID_OK event by default. If you wish to change this, call wxDialog::SetAffirmativeId - with the required identifier to be used. Or, override wxDialog::DoOK (return @false to - have wxWidgets simply call Close to dismiss the dialog). - - Smartphone dialogs do @e not have an OK button on the caption, and are closed - using one of the two menu buttons. You need to assign these using wxTopLevelWindow::SetLeftMenu - and wxTopLevelWindow::SetRightMenu, for example: - - @verbatim - #ifdef __SMARTPHONE__ - SetLeftMenu(wxID_OK); - SetRightMenu(wxID_CANCEL, _("Cancel")); - #elif defined(__POCKETPC__) - // No OK/Cancel buttons on PocketPC, OK on caption will close - #else - topsizer->Add( CreateButtonSizer( wxOK|wxCANCEL ), 0, wxEXPAND | wxALL, 10 ); - #endif - @endverbatim - - For implementing property sheets (flat tabs), use a wxNotebook with wxNB_FLAT|wxNB_BOTTOM - and have the notebook left, top and right sides overlap the dialog by about 3 pixels - to eliminate spurious borders. You can do this by using a negative spacing in your - sizer Add() call. The cross-platform property sheet dialog wxPropertySheetDialog is - provided, to show settings in the correct style on PocketPC and on other platforms. - - Notifications (bubble HTML text with optional buttons and links) will also be - implemented in the future for PocketPC. - - Modeless dialogs probably don't make sense for PocketPC and Smartphone, since - frames and dialogs are normally full-screen, and a modeless dialog is normally - intended to co-exist with the main application frame. - - @subsubsection page_port_wxmsw_wince_ppc Menubars and toolbars in PocketPC - - On PocketPC, a frame must always have a menubar, even if it's empty. - An empty menubar/toolbar is automatically provided for dialogs, to hide - any existing menubar for the duration of the dialog. - - Menubars and toolbars are implemented using a combined control, - but you can use essentially the usual wxWidgets API; wxWidgets will combine the menubar - and toolbar. However, there are some restrictions: - - @li You must create the frame's primary toolbar with wxFrame::CreateToolBar, - because this uses the special wxToolMenuBar class (derived from wxToolBar) - to implement the combined toolbar and menubar. Otherwise, you can create and manage toolbars - using the wxToolBar class as usual, for example to implement an optional - formatting toolbar above the menubar as Pocket Word does. But don't assign - a wxToolBar to a frame using SetToolBar - you should always use CreateToolBar - for the main frame toolbar. - @li Deleting and adding tools to wxToolMenuBar after Realize is called is not supported. - @li For speed, colours are not remapped to the system colours as they are - in wxMSW. Provide the tool bitmaps either with the correct system button background, - or with transparency (for example, using XPMs). - @li Adding controls to wxToolMenuBar is not supported. However, wxToolBar supports - controls. - - Unlike in all other ports, a wxDialog has a wxToolBar, automatically created - for you. You may either leave it blank, or access it with wxDialog::GetToolBar - and add buttons, then calling wxToolBar::Realize. You cannot set or recreate - the toolbar. - - @subsubsection page_port_wxmsw_wince_smart Menubars and toolbars in Smartphone - - On Smartphone, there are only two menu buttons, so a menubar is simulated - using a nested menu on the right menu button. Any toolbars are simply ignored on - Smartphone. - - @subsubsection page_port_wxmsw_wince_closing Closing windows in wxWinCE - - The guidelines state that applications should not have a Quit menu item, - since the user should not have to know whether an application is in memory - or not. The close button on a window does not call the window's - close handler; it simply hides the window. However, the guidelines say that - the Ctrl+Q accelerator can be used to quit the application, so wxWidgets - defines this accelerator by default and if your application handles - wxID_EXIT, it will do the right thing. - - @subsubsection page_port_wxmsw_wince_ctx Context menus in wxWinCE - - To enable context menus in PocketPC, you currently need to call wxWindow::EnableContextMenu, - a wxWinCE-only function. Otherwise the context menu event (wxContextMenuEvent) will - never be sent. This API is subject to change. - - Context menus are not supported in Smartphone. - - @subsubsection page_port_wxmsw_wince_ctrl Control differences on wxWinCE - - These controls and styles are specific to wxWinCE: - - @li wxTextCtrl The wxTE_CAPITALIZE style causes a CAPEDIT control to - be created, which capitalizes the first letter. - - These controls are missing from wxWinCE: - - @li MDI classes MDI is not supported under Windows CE. - @li wxMiniFrame Not supported under Windows CE. - - Tooltips are not currently supported for controls, since on PocketPC controls with - tooltips are distinct controls, and it will be hard to add dynamic - tooltip support. - - Control borders on PocketPC and Smartphone should normally be specified with - wxBORDER_SIMPLE instead of wxBORDER_SUNKEN. Controls will usually adapt - appropriately by virtue of their GetDefaultBorder() function, but if you - wish to specify a style explicitly you can use wxDEFAULT_CONTROL_BORDER - which will give a simple border on PocketPC and Smartphone, and the sunken border on - other platforms. - - @subsubsection page_port_wxmsw_wince_help Online help in wxWinCE - - You can use the help controller wxWinceHelpController which controls - simple @c .htm files, usually installed in the Windows directory. - See the Windows CE reference for how to format the HTML files. - - @subsubsection page_port_wxmsw_wince_install Installing your PocketPC and Smartphone applications - - To install your application, you need to build a CAB file using - the parameters defined in a special .inf file. The CabWiz program - in your SDK will compile the CAB file from the .inf file and - files that it specifies. - - For delivery, you can simply ask the user to copy the CAB file to the - device and execute the CAB file using File Explorer. Or, you can - write a program for the desktop PC that will find the ActiveSync - Application Manager and install the CAB file on the device, - which is obviously much easier for the user. - - Here are some links that may help. - - @li A setup builder that takes CABs and builds a setup program is at - http://www.eskimo.com/~scottlu/win/index.html. - @li Sample installation files can be found in - Windows CE Tools/wce420/POCKET PC 2003/Samples/Win32/AppInst. - @li An installer generator using wxPython can be found at - http://ppcquicksoft.iespana.es/ppcquicksoft/myinstall.html. - @li Miscellaneous Windows CE resources can be found at - http://www.orbworks.com/pcce/resources.html. - @li Installer creation instructions with a setup.exe for installing to PPC can be found at - http://www.pocketpcdn.com/articles/creatingsetup.html. - @li Microsoft instructions are at - http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnce30/html/appinstall30.asp?frame=true - @li Troubleshooting WinCE application installations: - http://support.microsoft.com/default.aspx?scid=KB;en-us;q181007 - - You may also check out demos/life/setup/wince which contains - scripts to create a PocketPC installation for ARM-based - devices. In particular, @c build.bat builds the distribution and - copies it to a directory called @c Deliver. - - @subsubsection page_port_wxmsw_wince_filedlg wxFileDialog in PocketPC - - Allowing the user to access files on memory cards, or on arbitrary - parts of the filesystem, is a pain; the standard file dialog only - shows folders under My Documents or folders on memory cards - (not the system or card root directory, for example). This is - a known problem for PocketPC developers. - - If you need a file dialog that allows access to all folders, - you can use wxGenericFileDialog instead. You will need to include - @c wx/generic/filedlgg.h. - - @subsubsection page_port_wxmsw_wince_evc Embedded Visual C++ Issues - - Run-time type information - - If you wish to use runtime type information (RTTI) with eVC++ 4, you need to download - an extra library, @c ccrtrtti.lib, and link with it. At the time of - writing you can get it from here: - - @verbatim - http://support.microsoft.com/kb/830482/en-us - @endverbatim - - Otherwise you will get linker errors similar to this: - - @verbatim - wxwince26d.lib(control.obj) : error LNK2001: unresolved external symbol "const type_info::`vftable'" (??_7type_info@@6B@) - @endverbatim - - Windows Mobile 5.0 emulator - - Note that there is no separate emulator configuration for Windows Mobile 5.0: the - emulator runs the ARM code directly. - - Visual Studio 2005 project files - - Unfortunately, Visual Studio 2005, required to build Windows Mobile 5.0 applications, - doesn't do a perfect job of converting the project files from eVC++ format. - - When you have converted the wxWidgets workspace, edit the configuration properties - for each configuration and in the Librarian, add a relative path ..\\..\\lib to - each library path. For example: - ..\\$(PlatformName)\\$(ConfigurationName)\\wx_mono.lib. - - Then, for a sample you want to compile, edit the configuration properties - and make sure - ..\\..\\lib\\$(PlatformName)\\$(ConfigurationName) - is in the Linker/General/Additional Library Directories property. - Also change the Linker/Input/Additional Dependencies property to something like - coredll.lib wx_mono.lib wx_wxjpeg.lib wx_wxpng.lib wx_wxzlib.lib wx_wxexpat.lib - commctrl.lib winsock.lib wininet.lib - (since the library names in the wxWidgets workspace were changed by VS 2005). - - Alternately, you could could edit all the names to be identical to the original eVC++ - names, but this will probably be more fiddly. - - @subsubsection page_port_wxmsw_wince_issues Remaining issues - - These are some of the remaining problems to be sorted out, and features - to be supported. - - @li Windows Mobile 5 issues. It is not possible to get the HMENU for - the command bar on Mobile 5, so the menubar functions need to be rewritten - to get the individual menus without use of a menubar handle. Also the - new Mobile 5 convention of using only two menus (and no bitmap buttons) needs to be - considered. - @li Sizer speed. Particularly for dialogs containing notebooks, - layout seems slow. Some analysis is required. - @li Notification boxes. The balloon-like notification messages, and their - icons, should be implemented. This will be quite straightforward. - @li SIP size. We need to be able to get the area taken up by the SIP (input panel), - and the remaining area, by calling SHSipInfo. We also may need to be able to show and hide - the SIP programmatically, with SHSipPreference. See also the Input Dialogs topic in - the Programming Windows CE guide for more on this, and how to have dialogs - show the SIP automatically using the WC_SIPREF control. - @li wxStaticBitmap. The About box in the "Life!" demo shows a bitmap that is - the correct size on the emulator, but too small on a VGA Pocket Loox device. - @li wxStaticLine. Lines don't show up, and the documentation suggests that - missing styles are implemented with WM_PAINT. - @li HTML control. PocketPC has its own HTML control which can be used for showing - local pages or navigating the web. We should create a version of wxHtmlWindow that uses this - control, or have a separately-named control (wxHtmlCtrl), with a syntax as close as possible - to wxHtmlWindow. - @li Tooltip control. PocketPC uses special TTBUTTON and TTSTATIC controls for adding - tooltips, with the tooltip separated from the label with a double tilde. We need to support - this using SetToolTip.(Unfortunately it does not seem possible to dynamically remove the tooltip, - so an extra style may be required.) - @li Focus. In the wxPropertySheetDialog demo on Smartphone, it's not possible to navigate - between controls. The focus handling in wxWidgets needs investigation. See in particular - src/common/containr.cpp, and note that the default OnActivate handler in src/msw/toplevel.cpp - sets the focus to the first child of the dialog. - @li OK button. We should allow the OK button on a dialog to be optional, perhaps - by using wxCLOSE_BOX to indicate when the OK button should be displayed. - @li Dynamic adaptation. We should probably be using run-time tests more - than preprocessor tests, so that the same WinCE application can run on different - versions of the operating system. - @li Modeless dialogs. When a modeless dialog is hidden with the OK button, it doesn't restore the - frame's menubar. See for example the find dialog in the dialogs sample. However, the menubar is restored - if pressing Cancel (the window is closed). This reflects the fact that modeless dialogs are - not very useful on Windows CE; however, we could perhaps destroy/restore a modeless dialog's menubar - on deactivation and activation. - @li Home screen plugins. Figure out how to make home screen plugins for use with wxWidgets - applications (see http://www.codeproject.com/ce/CTodayWindow.asp for inspiration). - Although we can't use wxWidgets to create the plugin (too large), we could perhaps write - a generic plugin that takes registry information from a given application, with - options to display information in a particular way using icons and text from - a specified location. - @li Further abstraction. We should be able to abstract away more of the differences - between desktop and mobile applications, in particular for sizer layout. - @li Dialog captions. The blue, bold captions on dialogs - with optional help button - - should be catered for, either by hard-wiring the capability into all dialogs and panels, - or by providing a standard component and sizer. - - - @section page_port_nativedocs Documentation for the native toolkits - - It's sometimes useful to interface directly with the underlying toolkit - used by wxWidgets to e.g. use toolkit-specific features. - In such case (or when you want to e.g. write a port-specific patch) it can be - necessary to use the underlying toolkit API directly: - - @li wxMSW port uses win32 API: see MSDN docs at http://msdn2.microsoft.com/en-us/library/ms649779.aspx - @li wxGTK port uses GTK+: see GTK+ 2.x docs at http://developer.gnome.org/doc/API/2.0/gtk/index.html +/** + +@page page_port Platform Details + +wxWidgets defines a common API across platforms, but uses the native graphical +user interface (GUI) on each platform, so your program will take on the native +look and feel that users are familiar with.

MGL itself runs on a variety of platforms +including DOS, Linux hardware (similar to the Linux framebuffer) +and various graphics systems such as Win32, X11 and OS/2. +Note that currently MGL for Linux runs only on x86-based systems. + +You will MGL 5.0 or higher which is available from + +http://www.scitechsoft.com/products/product_download.html + +In order to configure wxWidgets to compile wxMGL you will +need to type: + +@verbatim configure --with-mgl --with-universal @endverbatim + +Under DOS, wxMGL uses a dmake based make system. + +For further information, please see the files in docs/mgl +in the distribution. + + + +@section page_port_wxos2 wxOS2 + +wxOS2 is a port of wxWidgets for the IBM OS/2 Warp3 and Warp4 platforms. +This port is currently under construction and in beta phase. + + + +@section page_port_wxx11 wxX11 + +@htmlonly + +@endhtmlonly + +wxX11 is a port of wxWidgets using X11 (The X Window System) +as the underlying graphics backend. wxX11 draws its widgets +using the wxUniversal widget set which is now part of wxWidgets. +wxX11 is well-suited for a number of special applications such +as those running on systems with few resources (PDAs) or for +applications which need to use a special themed look. + +In order to configure wxWidgets to compile wxX11 you will +need to type: + +@verbatim configure --with-x11 --with-universal @endverbatim + +For further information, please see the files in docs/x11 +in the distribution. There is also a page on the use of +wxWidgets for embedded applications on the wxWidgets web site. + + + + + +@section page_port_wxmsw wxMSW + +@htmlonly + +@endhtmlonly + +wxMSW is a port of wxWidgets for the Windows platforms +including Windows 95, 98, ME, 2000, NT, XP in ANSI and +Unicode mode (for Windows 95 through the MSLU extension +library). wxMSW ensures native look and feel for XP +as well when using wxWidgets version 2.3.3 or higher. +wxMSW can be compile with a great variety of compilers +including MS VC++, Borland 5.5, MinGW32, Cygwin and +Watcom as well as cross-compilation with a Linux hosted +MinGW32 tool chain. + +For further information, please see the files in docs/msw +in the distribution. + +@subsection page_port_wxmsw_themedborders Themed borders on Windows + +Starting with wxWidgets 2.8.5, you can specify the @c wxBORDER_THEME style to have wxWidgets +use a themed border. Using the default XP theme, this is a thin 1-pixel blue border, +with an extra 1-pixel border in the window client background colour (usually white) to +separate the client area's scrollbars from the border. + +If you don't specify a border style for a wxTextCtrl in rich edit mode, wxWidgets now gives +the control themed borders automatically, where previously they would take the Windows 95-style +sunken border. Other native controls such as wxTextCtrl in non-rich edit mode, and wxComboBox, +already paint themed borders where appropriate. To use themed borders on other windows, such +as wxPanel, pass the @c wxBORDER_THEME style, or (apart from wxPanel) pass no border style. + +In general, specifying @c wxBORDER_THEME will cause a border of some kind to be used, chosen by the platform +and control class. To leave the border decision entirely to wxWidgets, pass @c wxBORDER_DEFAULT. +This is not to be confused with specifying @c wxBORDER_NONE, which says that there should +definitely be @e no border. + +@subsubsection page_port_wxmsw_themedborders_details More detail on border implementation + +The way that wxMSW decides whether to apply a themed border is as follows. +The theming code calls wxWindow::GetBorder() to obtain a border. If no border style has been +passed to the window constructor, GetBorder() calls GetDefaultBorder() for this window. +If wxBORDER_THEME was passed to the window constructor, GetBorder() calls GetDefaultBorderForControl(). + +The implementation of wxWindow::GetDefaultBorder() on wxMSW calls wxWindow::CanApplyThemeBorder() +which is a virtual function that tells wxWidgets whether a control can have a theme +applied explicitly (some native controls already paint a theme in which case we should not +apply it ourselves). Note that wxPanel is an exception to this rule because in many cases +we wish to create a window with no border (for example, notebook pages). So wxPanel +overrides GetDefaultBorder() in order to call the generic wxWindowBase::GetDefaultBorder(), +returning wxBORDER_NONE. + +@subsection page_port_wxmsw_wince wxWinCE + +wxWinCE is the name given to wxMSW when compiled on Windows CE devices; +most of wxMSW is common to Win32 and Windows CE but there are +some simplifications, enhancements, and differences in +behaviour. + +For building instructions, see docs/msw/wince in the +distribution, also the section about Visual Studio 2005 project +files below. The rest of this section documents issues you +need to be aware of when programming for Windows CE devices. + +@subsubsection page_port_wxmsw_wince_ General issues for wxWinCE programming + +Mobile applications generally have fewer features and +simpler user interfaces. Simply omit whole sizers, static +lines and controls in your dialogs, and use comboboxes instead +of listboxes where appropriate. You also need to reduce +the amount of spacing used by sizers, for which you can +use a macro such as this: + +@code +#if defined(__WXWINCE__) + #define wxLARGESMALL(large,small) small +#else + #define wxLARGESMALL(large,small) large +#endif + +// Usage +topsizer->Add( CreateTextSizer( message ), 0, wxALL, wxLARGESMALL(10,0) ); +@endcode + +There is only ever one instance of a Windows CE application running, +and wxWidgets will take care of showing the current instance and +shutting down the second instance if necessary. + +You can test the return value of wxSystemSettings::GetScreenType() +for a qualitative assessment of what kind of display is available, +or use wxGetDisplaySize() if you need more information. + +You can also use wxGetOsVersion to test for a version of Windows CE at +run-time (see the next section). However, because different builds +are currently required to target different kinds of device, these +values are hard-wired according to the build, and you cannot +dynamically adapt the same executable for different major Windows CE +platforms. This would require a different approach to the way +wxWidgets adapts its behaviour (such as for menubars) to suit the +style of device. + +See the "Life!" example (demos/life) for an example of +an application that has been tailored for PocketPC and Smartphone use. + +@note don't forget to have this line in your .rc file, as for + desktop Windows applications: + +@verbatim #include "wx/msw/wx.rc" @endverbatim + +@subsubsection page_port_wxmsw_wince_sdk Testing for WinCE SDKs + +Use these preprocessor symbols to test for the different types of device or SDK: + +@li @b __SMARTPHONE__ Generic mobile devices with phone buttons and a small display +@li @b __PDA__ Generic mobile devices with no phone +@li @b __HANDHELDPC__ Generic mobile device with a keyboard +@li @b __WXWINCE__ Microsoft-powered Windows CE devices, whether PocketPC, Smartphone or Standard SDK +@li @b WIN32_PLATFORM_WFSP Microsoft-powered smartphone +@li @b __POCKETPC__ Microsoft-powered PocketPC devices with touch-screen +@li @b __WINCE_STANDARDSDK__ Microsoft-powered Windows CE devices, for generic Windows CE applications +@li @b __WINCE_NET__ Microsoft-powered Windows CE .NET devices (_WIN32_WCE is 400 or greater) + +wxGetOsVersion will return these values: + +@li @b wxWINDOWS_POCKETPC The application is running under PocketPC. +@li @b wxWINDOWS_SMARTPHONE The application is running under Smartphone. +@li @b wxWINDOWS_CE The application is running under Windows CE (built with the Standard SDK). + + +@subsubsection page_port_wxmsw_wince_sizing Window sizing in wxWinCE + +Top level windows (dialogs, frames) are created always full-screen. Fit() of sizers will not rescale top +level windows but instead will scale window content. + +If the screen orientation changes, the windows will automatically be resized +so no further action needs to be taken (unless you want to change the layout +according to the orientation, which you could detect in idle time, for example). +When input panel (SIP) is shown, top level windows (frames and dialogs) resize +accordingly (see wxTopLevelWindow::HandleSettingChange()). + +@subsubsection page_port_wxmsw_wince_toplevel Closing top-level windows in wxWinCE + +You won't get a wxCloseEvent when the user clicks on the X in the titlebar +on Smartphone and PocketPC; the window is simply hidden instead. However the system may send the +event to force the application to close down. + +@subsubsection page_port_wxmsw_wince_hibernation Hibernation in wxWinCE + +Smartphone and PocketPC will send a @c wxEVT_HIBERNATE to the application object in low +memory conditions. Your application should release memory and close dialogs, +and wake up again when the next @c wxEVT_ACTIVATE or @c wxEVT_ACTIVATE_APP message is received. +(@c wxEVT_ACTIVATE_APP is generated whenever a @c wxEVT_ACTIVATE event is received +in Smartphone and PocketPC, since these platforms do not support @c WM_ACTIVATEAPP.) + +@subsubsection page_port_wxmsw_wince_hwbutt Hardware buttons in wxWinCE + +Special hardware buttons are sent to a window via the @c wxEVT_HOTKEY event +under Smartphone and PocketPC. You should first register each required button with +wxWindow::RegisterHotKey(), and unregister the button when you're done with it. For example: + +@code +win->RegisterHotKey(0, wxMOD_WIN, WXK_SPECIAL1); +win->UnregisterHotKey(0); +@endcode + +You may have to register the buttons in a @c wxEVT_ACTIVATE event handler +since other applications will grab the buttons. + +There is currently no method of finding out the names of the special +buttons or how many there are. + +@subsubsection page_port_wxmsw_wince_dialogs Dialogs in wxWinCE + +PocketPC dialogs have an OK button on the caption, and so you should generally +not repeat an OK button on the dialog. You can add a Cancel button if necessary, but some dialogs +simply don't offer you the choice (the guidelines recommend you offer an Undo facility +to make up for it). When the user clicks on the OK button, your dialog will receive +a @c wxID_OK event by default. If you wish to change this, call wxDialog::SetAffirmativeId() +with the required identifier to be used. Or, override wxDialog::DoOK() (return @false to +have wxWidgets simply call Close to dismiss the dialog). + +Smartphone dialogs do @e not have an OK button on the caption, and are closed +using one of the two menu buttons. You need to assign these using wxTopLevelWindow::SetLeftMenu +and wxTopLevelWindow::SetRightMenu(), for example: + +@code +#ifdef __SMARTPHONE__ + SetLeftMenu(wxID_OK); + SetRightMenu(wxID_CANCEL, _("Cancel")); +#elif defined(__POCKETPC__) + // No OK/Cancel buttons on PocketPC, OK on caption will close +#else + topsizer->Add( CreateButtonSizer( wxOK|wxCANCEL ), 0, wxEXPAND | wxALL, 10 ); +#endif +@endcode + +For implementing property sheets (flat tabs), use a wxNotebook with @c wxNB_FLAT|wxNB_BOTTOM +and have the notebook left, top and right sides overlap the dialog by about 3 pixels +to eliminate spurious borders. You can do this by using a negative spacing in your +sizer Add() call. The cross-platform property sheet dialog wxPropertySheetDialog is +provided, to show settings in the correct style on PocketPC and on other platforms. + +Notifications (bubble HTML text with optional buttons and links) will also be +implemented in the future for PocketPC. + +Modeless dialogs probably don't make sense for PocketPC and Smartphone, since +frames and dialogs are normally full-screen, and a modeless dialog is normally +intended to co-exist with the main application frame. + +@subsubsection page_port_wxmsw_wince_ppc Menubars and toolbars in PocketPC + +On PocketPC, a frame must always have a menubar, even if it's empty. +An empty menubar/toolbar is automatically provided for dialogs, to hide +any existing menubar for the duration of the dialog. + +Menubars and toolbars are implemented using a combined control, +but you can use essentially the usual wxWidgets API; wxWidgets will combine the menubar +and toolbar. However, there are some restrictions: + +@li You must create the frame's primary toolbar with wxFrame::CreateToolBar(), +because this uses the special wxToolMenuBar class (derived from wxToolBar) +to implement the combined toolbar and menubar. Otherwise, you can create and manage toolbars +using the wxToolBar class as usual, for example to implement an optional +formatting toolbar above the menubar as Pocket Word does. But don't assign +a wxToolBar to a frame using SetToolBar - you should always use CreateToolBar +for the main frame toolbar. +@li Deleting and adding tools to wxToolMenuBar after Realize is called is not supported. +@li For speed, colours are not remapped to the system colours as they are +in wxMSW. Provide the tool bitmaps either with the correct system button background, +or with transparency (for example, using XPMs). +@li Adding controls to wxToolMenuBar is not supported. However, wxToolBar supports +controls. + +Unlike in all other ports, a wxDialog has a wxToolBar, automatically created +for you. You may either leave it blank, or access it with wxDialog::GetToolBar() +and add buttons, then calling wxToolBar::Realize(). You cannot set or recreate +the toolbar. + +@subsubsection page_port_wxmsw_wince_smart Menubars and toolbars in Smartphone + +On Smartphone, there are only two menu buttons, so a menubar is simulated +using a nested menu on the right menu button. Any toolbars are simply ignored on +Smartphone. + +@subsubsection page_port_wxmsw_wince_closing Closing windows in wxWinCE + +The guidelines state that applications should not have a Quit menu item, +since the user should not have to know whether an application is in memory +or not. The close button on a window does not call the window's +close handler; it simply hides the window. However, the guidelines say that +the Ctrl+Q accelerator can be used to quit the application, so wxWidgets +defines this accelerator by default and if your application handles +wxID_EXIT, it will do the right thing. + +@subsubsection page_port_wxmsw_wince_ctx Context menus in wxWinCE + +To enable context menus in PocketPC, you currently need to call wxWindow::EnableContextMenu(), +a wxWinCE-only function. Otherwise the context menu event (wxContextMenuEvent) will +never be sent. This API is subject to change. + +Context menus are not supported in Smartphone. + +@subsubsection page_port_wxmsw_wince_ctrl Control differences on wxWinCE + +These controls and styles are specific to wxWinCE: + +@li wxTextCtrl The @c wxTE_CAPITALIZE style causes a CAPEDIT control to +be created, which capitalizes the first letter. + +These controls are missing from wxWinCE: + +@li MDI classes MDI is not supported under Windows CE. +@li wxMiniFrame Not supported under Windows CE. + +Tooltips are not currently supported for controls, since on PocketPC controls with +tooltips are distinct controls, and it will be hard to add dynamic +tooltip support. + +Control borders on PocketPC and Smartphone should normally be specified with +@c wxBORDER_SIMPLE instead of @c wxBORDER_SUNKEN. Controls will usually adapt +appropriately by virtue of their GetDefaultBorder() function, but if you +wish to specify a style explicitly you can use @c wxDEFAULT_CONTROL_BORDER +which will give a simple border on PocketPC and Smartphone, and the sunken border on +other platforms. + +@subsubsection page_port_wxmsw_wince_help Online help in wxWinCE + +You can use the help controller wxWinceHelpController which controls +simple @c .htm files, usually installed in the Windows directory. +See the Windows CE reference for how to format the HTML files. + +@subsubsection page_port_wxmsw_wince_install Installing your PocketPC and Smartphone applications + +To install your application, you need to build a CAB file using +the parameters defined in a special .inf file. The CabWiz program +in your SDK will compile the CAB file from the .inf file and +files that it specifies. + +For delivery, you can simply ask the user to copy the CAB file to the +device and execute the CAB file using File Explorer. Or, you can +write a program for the desktop PC that will find the ActiveSync +Application Manager and install the CAB file on the device, +which is obviously much easier for the user. + +Here are some links that may help. + +@li A setup builder that takes CABs and builds a setup program is at + http://www.eskimo.com/~scottlu/win/index.html. +@li Sample installation files can be found in + Windows CE Tools/wce420/POCKET PC 2003/Samples/Win32/AppInst. +@li An installer generator using wxPython can be found at + http://ppcquicksoft.iespana.es/ppcquicksoft/myinstall.html. +@li Miscellaneous Windows CE resources can be found at + http://www.orbworks.com/pcce/resources.html. +@li Installer creation instructions with a setup.exe for installing to PPC can be found at + http://www.pocketpcdn.com/articles/creatingsetup.html. +@li Microsoft instructions are at + http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnce30/html/appinstall30.asp?frame=true +@li Troubleshooting WinCE application installations: + http://support.microsoft.com/default.aspx?scid=KB;en-us;q181007 + +You may also check out demos/life/setup/wince which contains +scripts to create a PocketPC installation for ARM-based +devices. In particular, @c build.bat builds the distribution and +copies it to a directory called @c Deliver. + +@subsubsection page_port_wxmsw_wince_filedlg wxFileDialog in PocketPC + +Allowing the user to access files on memory cards, or on arbitrary +parts of the filesystem, is a pain; the standard file dialog only +shows folders under My Documents or folders on memory cards +(not the system or card root directory, for example). This is +a known problem for PocketPC developers. + +If you need a file dialog that allows access to all folders, +you can use wxGenericFileDialog instead. You will need to include +@c wx/generic/filedlgg.h. + +@subsubsection page_port_wxmsw_wince_evc Embedded Visual C++ Issues + +Run-time type information + +If you wish to use runtime type information (RTTI) with eVC++ 4, you need to download +an extra library, @c ccrtrtti.lib, and link with it. At the time of +writing you can get it from here: + +@verbatim +http://support.microsoft.com/kb/830482/en-us +@endverbatim + +Otherwise you will get linker errors similar to this: + +@verbatim +wxwince26d.lib(control.obj) : error LNK2001: unresolved external symbol "const type_info::`vftable'" (??_7type_info@@6B@) +@endverbatim + +Windows Mobile 5.0 emulator + +Note that there is no separate emulator configuration for Windows Mobile 5.0: the +emulator runs the ARM code directly. + +Visual Studio 2005 project files + +Unfortunately, Visual Studio 2005, required to build Windows Mobile 5.0 applications, +doesn't do a perfect job of converting the project files from eVC++ format. + +When you have converted the wxWidgets workspace, edit the configuration properties +for each configuration and in the Librarian, add a relative path ..\\..\\lib to +each library path. For example: +..\\$(PlatformName)\\$(ConfigurationName)\\wx_mono.lib. + +Then, for a sample you want to compile, edit the configuration properties +and make sure +..\\..\\lib\\$(PlatformName)\\$(ConfigurationName) +is in the Linker/General/Additional Library Directories property. +Also change the Linker/Input/Additional Dependencies property to something like +coredll.lib wx_mono.lib wx_wxjpeg.lib wx_wxpng.lib wx_wxzlib.lib wx_wxexpat.lib + commctrl.lib winsock.lib wininet.lib +(since the library names in the wxWidgets workspace were changed by VS 2005). + +Alternately, you could could edit all the names to be identical to the original eVC++ +names, but this will probably be more fiddly. + +@subsubsection page_port_wxmsw_wince_issues Remaining issues + +These are some of the remaining problems to be sorted out, and features +to be supported. + +@li Windows Mobile 5 issues. It is not possible to get the HMENU for +the command bar on Mobile 5, so the menubar functions need to be rewritten +to get the individual menus without use of a menubar handle. Also the +new Mobile 5 convention of using only two menus (and no bitmap buttons) needs to be +considered. +@li Sizer speed. Particularly for dialogs containing notebooks, +layout seems slow. Some analysis is required. +@li Notification boxes. The balloon-like notification messages, and their +icons, should be implemented. This will be quite straightforward. +@li SIP size. We need to be able to get the area taken up by the SIP (input panel), +and the remaining area, by calling SHSipInfo. We also may need to be able to show and hide +the SIP programmatically, with SHSipPreference. See also the Input Dialogs topic in +the Programming Windows CE guide for more on this, and how to have dialogs +show the SIP automatically using the @c WC_SIPREF control. +@li wxStaticBitmap. The About box in the "Life!" demo shows a bitmap that is +the correct size on the emulator, but too small on a VGA Pocket Loox device. +@li wxStaticLine. Lines don't show up, and the documentation suggests that +missing styles are implemented with @c WM_PAINT. +@li HTML control. PocketPC has its own HTML control which can be used for showing +local pages or navigating the web. We should create a version of wxHtmlWindow that uses this +control, or have a separately-named control (wxHtmlCtrl), with a syntax as close as possible +to wxHtmlWindow. +@li Tooltip control. PocketPC uses special TTBUTTON and TTSTATIC controls for adding +tooltips, with the tooltip separated from the label with a double tilde. We need to support +this using SetToolTip.(Unfortunately it does not seem possible to dynamically remove the tooltip, +so an extra style may be required.) +@li Focus. In the wxPropertySheetDialog demo on Smartphone, it's not possible to navigate +between controls. The focus handling in wxWidgets needs investigation. See in particular +src/common/containr.cpp, and note that the default OnActivate handler in src/msw/toplevel.cpp +sets the focus to the first child of the dialog. +@li OK button. We should allow the OK button on a dialog to be optional, perhaps +by using @c wxCLOSE_BOX to indicate when the OK button should be displayed. +@li Dynamic adaptation. We should probably be using run-time tests more +than preprocessor tests, so that the same WinCE application can run on different +versions of the operating system. +@li Modeless dialogs. When a modeless dialog is hidden with the OK button, it doesn't restore the +frame's menubar. See for example the find dialog in the dialogs sample. However, the menubar is restored +if pressing Cancel (the window is closed). This reflects the fact that modeless dialogs are +not very useful on Windows CE; however, we could perhaps destroy/restore a modeless dialog's menubar +on deactivation and activation. +@li Home screen plugins. Figure out how to make home screen plugins for use with wxWidgets +applications (see http://www.codeproject.com/ce/CTodayWindow.asp for inspiration). +Although we can't use wxWidgets to create the plugin (too large), we could perhaps write +a generic plugin that takes registry information from a given application, with +options to display information in a particular way using icons and text from +a specified location. +@li Further abstraction. We should be able to abstract away more of the differences +between desktop and mobile applications, in particular for sizer layout. +@li Dialog captions. The blue, bold captions on dialogs - with optional help button - +should be catered for, either by hard-wiring the capability into all dialogs and panels, +or by providing a standard component and sizer. + + +@section page_port_nativedocs Documentation for the native toolkits + +It's sometimes useful to interface directly with the underlying toolkit +used by wxWidgets to e.g. use toolkit-specific features. +In such case (or when you want to e.g. write a port-specific patch) it can be +necessary to use the underlying toolkit API directly: + +@li wxMSW port uses win32 API: see MSDN docs at http://msdn2.microsoft.com/en-us/library/ms649779.aspx +@li wxGTK port uses GTK+: see GTK+ 2.x docs at http://developer.gnome.org/doc/API/2.0/gtk/index.html +@li wxMac port uses the Carbon API: see Carbon docs at http://developer.apple.com/carbon +@li wxCocoa port uses the Cocoa API: see Cocoa docs at http://developer.apple.com/carbon */
