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.

[pygame] BUG: Different events when I enable OpenGL
If I enable OpenGL on my display, teh evebnt system starts behaving
differntly.
The following code prints all the events I am interrested in if i do
not
enable OpenGL. If I enable it however, events from the touchscreen
and stylus
are not reaching the event queue.
Note that this also happens for the simulated mouse events that
windows
generates for these input devices. When I dont enable OpenGL, and just
get the
normal mouse events (no fancy windows touchwindow, or using
pymt.SYWMEVENT),
everything is fine. If I enable OpenGL however, mouse events are not
generated
when I use touch or stylus (although they move/controll the system
mouse
cursor)
I am using pygame 1.9.1 with Python 2.6.2 on Windows 7.
import pygame
import ctypes
#if I uncomment this line, the window does not produce teh same events
#without it it works just fine!!
#display_flag = pygame.OPENGL
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)
while True:
for event in pygame.event.get():
if event.type == pygame.SYSWMEVENT:
print event
[pygame] Re: Multiple mice on windows
Hey Oscar! great work. this is a really cool feature and your code seem to work fine. I am having trouble however trying to integrate the code you had with pyglet. I know this is a pygame mailing list, and maybe you dont know anything about pyglet. but i am trying to add multi-mouse support to an application i have already written in pyglet. If I instantiate your rawinputreader. pyglet's main EventLoop throws an exception as soon as I move any of the mice. If you have any idea why this might be happpening I'd appreciate some input. Here is the traceback I am getting (I am just instantiating the rawinputreader and a pyglet window). If I dont instatiate the rawinputreader everything works fine. Traceback (most recent call last): File "C:\Documents and Settings\Thomas Hansen\workspace\multipoint \src\test.py", line 73, in rawEventLoop().run() File "C:\Python25\Lib\site-packages\pyglet\app\win32.py", line 67, in run _user32.DispatchMessageW(ctypes.byref(msg)) WindowsError: exception: priviledged instruction On Jun 12, 5:35 pm, "Oscar Lindberg" <[EMAIL PROTECTED]> wrote: > Hi, > > I just uploaded an early beta of something I've been fiddling around with on > Windows: > > http://pymultimouse.googlecode.com/files/pymultimouse0.1.zip > > If you download it and run the pygamedemo.py, you will see an empty screen. > When you start moving around all you mice connected to the computer, each > mouse gets a mouse pointer of its own. > > I would be happy if you guys could try it out and give me some feedback.
