Re: GtkImage size

[Barry Demchak <vendors tpsoft com>]

It's what you get back when you call gtk_hpaned_new. It's a container 
having  a left rectangle and a right rectangle and a moveable bar between 
them. So, my concern is the resizing of the rectangles as a result of what 
the user could do with the mouse.

See:
