GdkDrawingArea on GtkImage

Question

How can I impose GdkDrawingArea on the GtkImage for painting on an image, for example?

Answer 1

GtkDrawingArea and GtkImage are different classes, so you must choose one of them. You can still draw on GtkImage (and on any other widget), by connecting to expose_event signal.

You could also use plain GtkDrawingArea - displaying image is a matter of calling gdk_draw_pixbuf function.
