Date: Sun, 22 Mar 2009 12:52:29 +0000 From: Luke Benstead Subject: OpenGL 3.0 Context Creation I've attached a patch which implements OpenGL 3.x context creation on the latest SVN. I've added two options to SDL_GL_SetAttribute, these are SDL_GL_CONTEXT_MAJOR_VERSION and SDL_GL_CONTEXT_MINOR_VERSION. These default to 2 and 1 respectively. If the major version is less than 3 then the current context creation method is used, otherwise the appropriate new context creation function is called (depending on the platform). Sample code: if (SDL_Init(SDL_INIT_VIDEO) != 0) { printf("Unable to initialize SDL: %s\n", SDL_GetError()); return 1; } SDL_GL_SetAttribute(SDL_GL_CONTEXT_MAJOR_VERSION, 3); //Without these 2 lines, SDL will create a GL 2.x context SDL_GL_SetAttribute(SDL_GL_CONTEXT_MINOR_VERSION, 0); SDL_GL_SetAttribute(SDL_GL_DOUBLEBUFFER, 1); SDL_Surface* screen = SDL_SetVideoMode( 640, 480, 16, SDL_OPENGL | SDL_FULLSCREEN ); I've implemented context creation on both Win32 and X and run basic tests on both. This patch doesn't provide access to all the options allowed by the new context creation (e.g. shared contexts, forward compatible contexts) but they can be added pretty easily.

SDL_PushEvent \- Pushes an event onto the event queue
.SH "SYNOPSIS"
.PP
\fB#include "SDL\&.h"
.sp
\fBint \fBSDL_PushEvent\fP\fR(\fBSDL_Event *event\fR);
.SH "DESCRIPTION"
.PP
The event queue can actually be used as a two way communication channel\&. Not only can events be read from the queue, but the user can also push their own events onto it\&. \fBevent\fR is a pointer to the event structure you wish to push onto the queue\&.

\fBNote:  
.PP
Pushing device input events onto the queue doesn\&'t modify the state of the device within SDL\&.
.RE
.SH "RETURN VALUE"
.PP
Returns \fB0\fR on success or \fB-1\fR if the event couldn\&'t be pushed\&.
.SH "EXAMPLES"
