Hi
I also experience some strange issues like that when i was starting to learn
and i found very
usefull to disable the doublebuffering of the drawing area to have more control
of what is
happening. Also, i would also suggest you to add a button and draw only when
the button
is clicked .. the drawing area takes time to setup itself ... i don't know when
the drawingArea
is really ready to draw.
So what i did was basically ...
public MainWindow (): base (Gtk.WindowType.Toplevel)
{
// Build the main GUI
Build ();
// disable the doublebuffer
// My drawing area is named canvas
this.canvas.DoubleBuffered = false;
}
Also, try this and also if this does not work, try to add a button and trigger
the drawing of the drawing area from the button press event so that you are
pretty sure that all GTK init is done.
regards,
Marcelo

Thank you for your replying.
Now I just have removed "GdkWindow.Clear();" from the code,
but the window still shows nothing...
