+and toolbar. However, there are some restrictions:
+
+\itemsep=0pt
+\begin{itemize}
+\item 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.
+\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,

+\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, and a wxFileDialog
+replacement will need to be written.

 \item {\bf Font dialog.} The generic font dialog is currently used, which

 \item {\bf Sizer speed.} Particularly for dialogs containing notebooks,

 \item {\bf Notification boxes.} The balloon-like notification messages, and their
 icons, should be implemented. This will be quite straightforward.

 the SIP programmatically, with SHSipPreference. See also the {\it Input Dialogs} topic in

 \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 Data storage.} Methods for saving data on Smartphone need to be supported and documented.
 \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
