From: Mike Gorchak <mike@malva.ua>
Subject: New QNX patches
- Added more error check to avoid SEGFAULTS;
- Fixed bug in update function for SDL_HWSURFACE. BTW: update is much
faster than before.
- Added checks for SDL_HWSURFACE flag, chosen bpp must be equal to
desktop bpp for SDL_HWSURFACE.
- Fixed overlay bug, no more SEGFAULTS.

Both the absolute (\fBx\fR and \fBy\fR) and relative (\fBxrel\fR and \fByrel\fR) coordinates are reported along with the current button states (\fBstate\fR)\&. The button state can be interpreted using the \fBSDL_BUTTON\fP macro (see \fI\fBSDL_GetMouseState\fP\fR)\&. .PP If the cursor is hidden (\fI\fBSDL_ShowCursor\fP(0)\fR) and the input is grabbed (\fI\fBSDL_WM_GrabInput\fP(SDL_GRAB_ON)\fR), then the mouse will give relative motion events even when the cursor reaches the edge fo the screen\&. This is currently only implemented on Windows and Linux/Unix-a-likes\&. .SH "SEE ALSO" .PP \fI\fBSDL_Event\fR\fR, \fI\fBSDL_MouseButtonEvent\fR\fR ...\" created by instant / docbook-to-man, Tue 11 Sep 2001, 22:59
