       while(gtk_events_pending()) gtk_main_iteration();

As you will see, the black rectangle will vanish if you move another
window ontop of yours and away again.

This is because a widget has to be redrawn, whenever it is newly
exposed. There is a event that tells you that the widget has been
exposed: GdkEventExpose

Take a look at the tutorial and/or example scribble_simple. You will get
the idea very soon, i think.
