Multiple windows?
« on: October 15, 2007, 06:48:51 am »
How do you handle creating and running events for multiple windows?  Would your main loop simply have:

while(...) {
    while(window1.GetEvent(Event)) { }
    while(window2.GetEvent(Event)) { }

    window1.SetCurrent();
    window1.Display();

    window2.SetCurrent();
    window2.Display();
}

Is this correct?  How are different rendering contexts handled?  Is a different context created for each window?  Also, how would you handle window creation if you wanted the 2 windows to SHARE a context?

Your code should be correct.

Every SFML window has its own OpenGL context, and all these contexts are shared.

So each created window has access to the other's textures, buffers, ect...?
