Title: win.pushGLStates and win.popGLStates vs win.resetGLStates
Post by: Flaze07 on July 10, 2017, 06:09:58 am

hi so I checked these out because I want to draw with both sfgui and sfml
and with this code nothing is drawn

Code: [Select]

        win.pushGLStates();
        if (option == Option::rectangle)
        {
            win.draw(rect);
        }
        win.popGLStates();
       sfgui.Display(win)

but this one works

Code: [Select]

        win.resetGLStates();
        sfgui.Display(win);
        win.resetGLStates();
        if (option == Option::rectangle)
        {
            win.draw(rect);
        }

full code

The basic promise is simple: Keep the OpenGL state vs. starting fresh. If you're using `ressetGLSStates()`, you're always starting fresh, which is perfectly fine. It's just a different approach to the same problem.
