\section{wxMSW port}\label{wxmswport}
wxMSW is a port of wxWidgets for the Windows platforms
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{General issues for wxWinCE programming}
See the "Life!" example (demos/life) for an example of
an application that has been tailored for PocketPC and Smartphone use.
+{\bf Note:} don't forget to have this line in your .rc file, as for
+desktop Windows applications:
+
+\begin{verbatim}
+#include "wx/msw/wx.rc"
+\end{verbatim}
+
\subsubsection{Testing for WinCE SDKs}
Use these preprocessor symbols to test for the different types of device or SDK:
\subsubsection{Window sizing in wxWinCE}
-When creating frames and dialogs, create them with wxDefaultPosition and
-wxDefaultSize, which will tell WinCE to create them full-screen.
-
-Don't call Fit() and Centre(), so the content sizes to
-the window rather than fitting the window to the content. (We really need a single API call
-that will do the right thing on each platform.)
+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).
-However, if the input panel (SIP) is shown, windows do not yet resize accordingly. This will
-be implemented soon.
+When input panel (SIP) is shown, top level windows (frames and dialogs) resize
+accordingly (see \helpref{wxTopLevelWindow::HandleSettingChange}{wxtoplevelwindowhandlesettingchange}).
+
+\subsubsection{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{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{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 \helpref{wxWindow::RegisterHotKey}{wxwindowregisterhotkey},
+and unregister the button when you're done with it. For example:
+
+\begin{verbatim}
+ win->RegisterHotKey(0, wxMOD_WIN, WXK_SPECIAL1);
+ win->UnregisterHotKey(0);
+\end{verbatim}
+
+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{Dialogs in wxWinCE}
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
+a wxID\_OK event by default. If you wish to change this, call \helpref{wxDialog::SetAffirmativeId}{wxdialogsetaffirmativeid}
+with the required identifier to be used. Or, override \helpref{wxDialog::DoOK}{wxdialogdook} (return false to
have wxWidgets simply call Close to dismiss the dialog).
Smartphone dialogs do {\it 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:
+using one of the two menu buttons. You need to assign these using \helpref{wxTopLevelWindow::SetLeftMenu}{wxtoplevelwindowsetleftmenu}
+and \helpref{wxTopLevelWindow::SetRightMenu}{wxtoplevelwindowsetrightmenu}, for example:
\begin{verbatim}
#ifdef __SMARTPHONE__
#endif
\end{verbatim}
-For implementing property sheets (flat tabs), use a wxNotebook with wxNB_FLAT|wxNB_BOTTOM
+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 \helpref{wxPropertySheetDialog}{wxpropertysheetdialog} is
\wxheading{Menubars and toolbars in PocketPC}
On PocketPC, a frame must always have a menubar, even if it's empty.
-An empty menubar is automatically provided for dialogs, to hide
+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,
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.
-\item Deleting and adding tools to wxToolMenuBar is not supported.
+\item Deleting and adding tools to wxToolMenuBar after Realize is called is not supported.
+\item 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).
+\item Adding controls to wxToolMenuBar is not supported. However, wxToolBar supports
+controls.
\end{itemize}
+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.
+
\wxheading{Menubars and toolbars in Smartphone}
On Smartphone, there are only two menu buttons, so a menubar is simulated
defines this accelerator by default and if your application handles
wxID\_EXIT, it will do the right thing.
+\subsubsection{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{Control differences on wxWinCE}
+These controls and styles are specific to wxWinCE:
+
+\itemsep=0pt
+\begin{itemize}
+\item {\bf wxTextCtrl} The wxTE\_CAPITALIZE style causes a CAPEDIT control to
+be created, which capitalizes the first letter.
+\end{itemize}
+
These controls are missing from wxWinCE:
\itemsep=0pt
\begin{itemize}
-\item {\bf wxCheckListBox} This can be implemented using a wxListCtrl in report mode
-with checked/unchecked images.
+\item {\bf MDI classes} MDI is not supported under Windows CE.
+\item {\bf wxMiniFrame} Not supported under Windows CE.
\end{itemize}
-This section is currently incomplete.
+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
+wxSIMPLE\_BORDER instead of wxSUNKEN\_BORDER. 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{Online help in wxWinCE}
You can use the help controller wxWinceHelpController which controls
simple {\tt .htm} files, usually installed in the Windows directory.
+See the Windows CE reference for how to format the HTML files.
+
+\subsubsection{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.
+

+
+You may also check out {\tt demos/life/setup/wince} which contains
+scripts to create a PocketPC installation for ARM-based
+devices. In particular, {\tt build.bat} builds the distribution and
+copies it to a directory called {\tt Deliver}.
+
+\subsubsection{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
+{\tt wx/generic/filedlgg.h}.
+
+\subsubsection{Embedded Visual C++ Issues}
+
+\wxheading{Run-time type information}
+
+If you wish to use runtime type information (RTTI) with eVC++ 4, you need to download
+an extra library, {\tt ccrtrtti.lib}, and link with it. At the time of
+writing you can get it from here:
+
+\begin{verbatim}
+http://support.microsoft.com/kb/830482/en-us
+\end{verbatim}
+
+Otherwise you will get linker errors similar to this:
+
+\begin{verbatim}
+wxwince26d.lib(control.obj) : error LNK2001: unresolved external symbol "const type_info::`vftable'" (??_7type_info@@6B@)
+\end{verbatim}
+
+\wxheading{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.
+
+\wxheading{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 ..$\backslash$..$\backslash$lib to
+each library path. For example: {\tt ..$\backslash$\$(PlatformName)$\backslash$\$(ConfigurationName)$\backslash$wx\_mono.lib}.
+
+Then, for a sample you want to compile, edit the configuration properties
+and make sure {\tt ..$\backslash$..$\backslash$lib$\backslash$\$(PlatformName)$\backslash$\$(ConfigurationName)} is in the Linker/General/Additional
+Library Directories property. Also change the Linker/Input/Additional Dependencies
+property to something like {\tt coredll.lib wx\_mono.lib wx\_wxjpeg.lib wx\_wxpng.lib wx\_wxzlib.lib wx\_wxexpat.lib commctrl.lib winsock.lib wininet.lib}\rtfsp
+(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{Remaining issues}
\itemsep=0pt
\begin{itemize}
-\item {\bf Font dialog.} The generic font dialog is currently used, which
-needs to be simplified (and speeded up).
+\item {\bf 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.
\item {\bf Sizer speed.} Particularly for dialogs containing notebooks,
layout seems slow. Some analysis is required.
\item {\bf Notification boxes.} The balloon-like notification messages, and their
icons, should be implemented. This will be quite straightforward.
-\item {\bf WM\_SETTINGCHANGE.} This message needs to be handled by calling SHHandleWMSettingChange.
-\item {\bf WM\_ACTIVATE.} This message needs to be handled by calling SHHandleWMActivate.
-\item {\bf WM\_HIBERNATE.} We need to handle this message.
\item {\bf 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 {\it Input Dialogs} topic in
the {\it Programming Windows CE} guide for more on this, and how to have dialogs
-show the SIP automatically using the WC_SIPREF control.
-\item {\bf Drawing.} The "Life!" demo shows some droppings being left on the window,
-indicating that drawing works a bit differently between desktop and mobile versions of
-Win32.
+show the SIP automatically using the WC\_SIPREF control.
\item {\bf 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.
\item {\bf wxStaticLine.} Lines don't show up, and the documentation suggests that
missing styles are implemented with WM\_PAINT.
-\item {\bf wxCheckListBox.} This class needs to be implemented in terms of a wxListCtrl
-in report mode, using icons for checkbox states. This is necessary because owner-draw listboxes
-are not supported on Windows CE.
+\item {\bf 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.
+\item {\bf 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.)
+\item {\bf 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.
\item {\bf 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.
\item {\bf 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.
+\item {\bf 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.
\item {\bf Home screen plugins.} Figure out how to make home screen plugins for use with wxWidgets
applications (see {\tt 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 specified location.
\item {\bf Further abstraction.} We should be able to abstract away more of the differences
between desktop and mobile applications, in particular for sizer layout.
+\item {\bf 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.
