How do I set window titlebar icon and alt-tab icon in SDL2 / C++ / Visual Studio 2012 express program?

I have added a .rc file to my project with just the following: 

IDI_MAIN_ICON          ICON          "..\\..\\icon_artwork\\windows_icons\\project.ico"

The .ico file contains icons at 16x16, 32x32, 48x48 and 256x256 resolutions.

I see the icon in the taskbar and explorer (so there is no doubt the .ico is successfully embedded in the .exe), but I see the default Windows 7 application icon in the application's own title bar, and in alt-tab.

Is there a way to get the OS to see the embedded icon by itself in all cases, or do I need to write some application code for this? I notice that there is an SDL2 function

void SDL_SetWindowIcon(SDL_Window*  window, SDL_Surface* icon)

but that takes an SDL surface, not the embedded icon resource from the executable.

Any ideas gratefully received,
Tony

Solution

  • You should be able to get a SDL_Surface from a .png file using:

    SDL_Surface *IMG_Load(const char *file)

    then pass it to your SDL_SetWindowIcon(SDL_Window* window, SDL_Surface* icon) method. I don't think the IMG_Load(...) method takes .ico files, but a 32x32 .png version of your icon should work.
