You're confusing two completely different objects. A GtkDrawingArea is a widget class which is available for the development of widgets which need a window and a basic realize() function. A GdkDrawable is a base class for GdkWindow and GdkPixmap. You probably want to call gdk_pixmap_new() or something like that. > assertion 'drawable != NULL' failed... This means you're not really "sending it to some other function" properly. You're passing a NULL argument for the drawable, and it's failing. > Can anybody please let me know when this error comes and how to put the > pixmap into drawing area.... If you're just trying to display a pixmap, you should be using GtkPixmap (under 1.2) or GtkImage (under 2.0). For 1.2, the tutorial on www.gtk.org has details on how to use GtkPixmap.
