Re: [pygame] BUG: Different events when I enable OpenGL
hi,
opengl uses a slighty different video and event driver. So that
explains the different behaviour.
probably have a better chance of it getting fixed if you report your
bug here: bugzilla.libsdl.org
I'm guessing that the stylus uses a different method of updating the
mouse position... and the opengl method of getting events is not
working.
Maybe a work around would be to use pygame.mouse.get_pos() ?

I am using pygame 1.9.1 with Python 2.6.2 on Windows 7.

pygame.display.quit()
pygame.display.init()
pygame.display.set_mode((320, 240) display_flag)
pygame.event.set_allowed(pygame.SYSWMEVENT)
pygame.display.set_caption('pymt')
hwnd = ctypes.windll.user32.FindWindowA(None, pymt)
ctypes.windll.user32.RegisterTouchWindow(hwnd, 0)

Re: [pygame] BUG: Different events when I enable OpenGL
I see, I'll let the libsdl folks know, and see what they think about
that. The get_mouse thing might work for teh stylus, but not for
multi-touch :(
Is there a way to inject code, or attach handlers to the actual
underlying system window (instead of teh SDL abstraction) from python?
SDL must handle the windows mesage somewhere, but I dont know if that
is accessible at all through python. i tried using win32 hooks, but I
cant inject python code (the code has to be in a dll). I dont really
want to change the code in C/C++, because it would require user to
compile a custom version.

Hey Thomas,
you may want to double check that the hwnd you are getting is the right
one - those windows funcs would execute without an exception if they had
some kind of error or problem.
Also, the normal way to get an hwnd in pygame is this:
hwnd = pygame.display.get_wm_info()['window']
So you might want to do a quick check to see if the value from the
FindWindowA func matched what get_wm_info gives you.
