Re: [gtk-list] GdkGC!

[Hugo Varotto <hvarotto cs pitt edu>]

Hi Jesus,


To get the dimensions of the drawing area:

get a pointer to the desired drawing area

GtkWidget               *drawingarea;
drawingarea = get_widget (window1, "my_drawingarea");

and then refer to 

drawingarea->allocation.width
drawingarea->allocation.height


I'll look for some examples of how to allocate a color
