[Java-gnome-developer] DrawingArea or Drawable

[Breizh M. S. <fra...@bm...>]

Hi Everybody !

I am trying to use a DrawingArea but I do not know how to. Is there any 
documentation about it somewhere ?
This the code I am trying

        int width,height;
        org.gnu.gdk.Window GdkWindow = drawingarea.getParentWindow();
        width = GdkWindow.getWidth();
        height = GdkWindow.getHeight();
        GdkWindow.drawLine(0,0,100,100);
       
        drawingarea.setBackgroundColor(StateType.ACTIVE,Color.BLACK);   
        drawingarea.show();
        window.showAll();

But there is nothing to display. What's wrong ?

Thanks
Fanch.
