Q: drawing with cairo over a GtkBox not using GtkDrawingArea I program my application in C using GTK+3 and cairo.
is there a way to draw a line on top of a Vertical GtkBox ?
the thing is that I need to mark an area with a line. the area is a row of a vertical GtkBox, which is not a GtkDrawingArea.
is that possible?
any information regarding the issue would be greatly appreciated.

A: I'm using glade in order to create the Gtk Vertical Box.
I connected a callback to the draw signal and I marked 'After' in glade which actually calls my callback after the basic drawing. which allows me to draw on top of the elements inside it.
as simple as that ;)
