I have a pixmap displayed in a gdk window. Now I'd like to superimpose a rectangle to give the user feedback on the area she has selected with a mouse drag -- a 'wire frame' rectangle that doesn't cover up the pixmap.
Set the GC to XOR with gdk_gc_set_function (gc, GDK_XOR) and draw a white or black line. Draw it again on the same position to make it disappear again. :) Roland -- R.F.
