You can see example in test/dblbuffer.cpp
Use PG_Application.PumpIntoEventQueue(&event) to pump events into your
gui.

while (!done) { 
  /* Check for events */    
  ++frames;
  while ( SDL_PollEvent(&event) ) {
   app.PumpIntoEventQueue(&event);
  }

........

 PG_Widget::BulkBlit();

}

PG_Widget::BulkBlit is a static method, which blits all widgets and
draws cursor.
And do not forget to "SDL_Update" the screen!
