Description Vincent Vansuyt 2006-09-02 16:42:22 UTC 
Hello,

Sorry for my english, I'm french. I hope you will understand what I mean...

I use SDL 1.2.9 with OpenGL and a Windows 2000 pro PC.

I test the mouse position with the followings intructions :
SDL_Event event;
SDL_PollEvent(&event)
int x = event.motion.x;
int y = event.motion.y;

In 800x600 resolution, full srceen :
the top-left mouse position is in 0,0 -> OK
the bottom-right mouse position is 799,599 -> OK

In 800x600 resolution, windowed :
the top-left mouse position is in 0,0 -> OK
the bottom-right mouse position is 799,599 -> OK

In 1024x768 resolution, full screen :
the top-left mouse position is in 0,0 -> OK
the bottom-right mouse position is 1023,767 -> OK

In 1024x768 resolution, windowed :
the top-left mouse position is in 0,0 -> OK
the bottom-right mouse position is 1023,754 ->>>> NOK !!! It must be 767 in y !!

In 1280x960 resolution, full screen :
the top-left mouse position is in 0,0 -> OK
the bottom-right mouse position is 1279,959 -> OK

In 1280x960 resolution, windowed :
the top-left mouse position is in 0,0 -> OK
the bottom-right mouse position is 1279,959 -> OK

The problem come probably from the window size and the header bar size...
If the 1024x768 windowed works like the 800x600 or the 1280x960 windowed, it will be perfect...

Thanks.

I think this is probably fixed in SDL 1.2.11, can you retest?
Comment 2 Vincent Vansuyt 2006-09-24 04:19:25 UTC 
You THINK this is PROBALY... ?!!

I know now why it is so much bug in SDL : You don't do any test after coding !!!

Personnaly I have no time to install the 1.2.11 version. And I can't, the devPack 1.2.11 doesn't work with devCpp... 

Sorry.
Comment 3 Sam Lantinga 2006-09-24 12:21:32 UTC 
I can't reproduce it in 1.2.11, and I fixed several bugs with mouse position on Windows for 1.2.11, specifically relating to the window size and accounting for menu bars.  I don't maintain the devcpp packages, so if you don't have time to build it yourself you may be out of luck.
Comment 4 Ryan C. Gordon 2006-11-12 21:41:29 UTC 
Without further comment, I'm flagging this bug as fixed. If you are unsatisfied with SDL, you may return it for a full refund.
