Balloon-help or callout window

[Darryl Luff <darryl snakegully nu>]

Hi all,

I'm after a GTK widget that gives a 'balloon help' type display with a 
pointer that links to another widget. Like a comic talk bubble. I've 
found some discussions but no code.

Does anyone know of a widget available that does this, or an app that 
uses one?

Or if I need to do it myself, would I have to make a shaped window that 
included the space for the pointer, or is there a way to draw on the 
screen outside widgets?


Thanks a lot for any pointers.
