[SDL] App icon sometimes not appearing on window titlebar

[Ken Rogoway]

I ran into something similar.  You need to make sure you call
SDL_WM_SetIcon() before you call SDL_SetVideoMode().

Subject: [SDL] App icon sometimes not appearing on window titlebar

I'm just wondering if anyone knows what could cause this.  It mostly seems
to happen in Windows, but I've occasionally seen it Linux as well.

I'm referring to the icon which appears in the top left of the window, which
lists operations that can be performed.  I assumed this icon was set with
SDL_WM_SetIcon.  Strange this is, sometimes the icon doesn't appear in the
taskbar for the window either, and sometimes it does.  I can't see a pattern
for why it's happening.  Here's the relevant code, which loads from an XPM
file:

  SDL_Surface *surface = SDL_CreateRGBSurfaceFrom(icon, 32, 32, 32,
                         32 * 4, 0xFF0000, 0x00FF00, 0x0000FF,
                         0xFF000000);
  SDL_WM_SetIcon(surface, (unsigned char *) mask);

Anybody have any advice?

Steve
