\section{wxMSW port}\label{wxmswport}
wxMSW is a port of wxWidgets for the Windows platforms
For further information, please see the files in docs/msw
in the distribution.
+\subsection{Themed borders on Windows}\label{wxmswthemedborders}
+
+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 pass no border style.
+
+Note that in wxWidgets 2.9 and above, wxBORDER\_THEME is defined to be 0 and it is not necessary
+to pass the border style explicitly: wxWidgets will deduce the correct border style itself if there
+is none supplied. Because of the requirements of binary compatibility, this automatic border
+capability could not be put into wxWidgets 2.8 except for built-in, native controls. So in 2.8, the border
+must be specified for custom controls and windows.
+
+Since specifying wxBORDER\_THEME is defined as 0 and is the equivalent of abstaining on the
+border style decision, on non-Windows platforms a suitable border style will be chosen.
+This is not to be confused with specifying wxBORDER\_NONE, which says that there should
+definitely be {\it no} border.
+
+\wxheading{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.
+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{wxWinCE}\label{wxwince}
wxWinCE is the name given to wxMSW when compiled on Windows CE devices;
some simplifications, enhancements, and differences in
behaviour.
-For installation instructions, see docs/msw/wince in the
-distribution. The rest of this section documents issues you
+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}
win->UnregisterHotKey(0);
\end{verbatim}
-You may have to register the buttons in a wxEVT_ACTIVATE event handler
+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
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
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
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
+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{Online help in wxWinCE}
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, and a wxFileDialog
-replacement will need to be written.
+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
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.
\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 wxFileDialog.} A more flexible dialog needs to be written (probably using wxGenericFileDialog)
-that can access arbitrary locations.
+\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.
