Hi,
So I now thankfully have a simple wxPython script that creates a frame,
etc... Now I want it to act like a well-behaved CE application.
Ultimately, I'd like to post it to the wiki (at least as a hack). Hope the
formatting in this email comes through alright! Any help is greatly
appreciated.
From what I've learned recently, I want the script to:
1. start up the program without a shell, [see "\nopcceshell" registry
arg]
2. and a simple tap on a unique icon for the program from the Start >
Programs menu, Task bar, or File Explorer, etc. [make a shortcut in
"\Windows\Start Menu\Programs"]
3. be minimized by the Smart Close button [no problem here]
4. then be uniquely iconized to the Start/Task Menu [sort of
accomplished by #2]
5. and finally be brought forward again (maximized) when either the
user again clicks on the Task menu (or any other shortcut to the script)
[use win32gui.SetForegroundWindow(hwnd)]
6. (for now, trying to keep it simple, I'm not going to worry about
the hibernation, memory events that could cause spurious problems)
[wxEVT_ACTIVATE, etc.]
I'm attaching the following script which almost accomplishes (5). How to
accomplish (1-4) can be pieced together elsewhere. The main problem the
script now has are:
- if "\nopcceshell" is used, the busy clock persists [previous post
but in example] but the running script is brought forward as expected.
- if the pcceshell is used, and one calls
[_pcceshell_support.Busy(0)], then the call on line 31, [frame_class =
win32gui.GetClassName(frame.GetHandle())], returns the PythonCE shell
and not the frame of the script.
Best regards,
Matt

Regarding new info I have about solving this problem,
I'm thinking I either need to implement a WindowProc function that
processes messages sent to the window,
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winui/winui/windowsuserinterface/windowing/windowprocedures/windowprocedurereference/windowprocedurefunctions/windowproc.asp
or, hope that the WS_NONAVDONEBUTTON gets supported by wx and then ported
to the PPC (or learn to compile, etc. myself),
