<< There is a win32gui module, which exposes the Mobile windows API. >>
There should also be a win32api module and win32con module. I don't have
those in my installation, and haven't had luck finding them. win32con is
just a collection of constants, so the desktop version would be very, very
close with a few tweaks. And we can skip using win32api for a simple demo.
There's a bigger problem in that win32gui isn't working (or at least the
version I have). And it's also incomplete (even the desktop version is
missing some of the APIs).
Below is a sample that should create a window. You can run it on a desktop,
and it correctly creates the window. The print messages show up in the
console window confirming that the message pump is hooked in and getting the
WM_PAINT messages. Sadly, that's where I wanted to put code to put text on
the window, but DrawText() isn't implemented in win32gui.
Also the WM_DESTROY message happens, I manually issue a quit message, the
gui window closes, but the console window stays open. We never return from
the message pump.
Under CE, I see all those problems plus an issue that CE never paints the
window background. Also it leaves the hourglass cursor up. I do get a
window, and can drag it around by the title bar. I can even see that it is
getting Windows messages. But it's just not getting redrawn, so it's not
very useful yet.
