From: Rob
Subject: [SDL] SDL pre-release
OpenGL fails on the zipped pre-release source accessible from
http://www.libsdl.org/svn.php.
Appears to be following lines in sdl_wing.c (lines 341-345):
wglext = (const char *)this->glGetString(GL_EXTENSIONS);
if ( !SDL_strstr(wglext, "WGL_EXT_swap_control") ) {
this->gl_data->wglSwapIntervalEXT = NULL;
this->gl_data->wglGetSwapIntervalEXT = NULL;
}
glGetString is a null pointer, as are other gl function pointers, so call
fails. Never looked at sdl source before, so no further than that as yet.

| 18 \fBSDL_QuitEvent\fR is a member of the \fI\fBSDL_Event\fR\fR union and is used whan an event of type \fBSDL_QUIT\fP is reported\&. | |
| 19 .PP | |
| 20 As can be seen, the SDL_QuitEvent structure serves no useful purpose\&. The event itself, on the other hand, is very important\&. If you filter out or ignore a quit event then it is impossible for the user to close the window\&. On the other hand, if you do accept a quit event then the application window will be closed, and screen updates will still report success event though the application will no longer be visible\&. | |
