Re: GtkImage size

[Barry Demchak <vendors tpsoft com>]

Uh huh ...

That's a pretty good idea. I'll follow up on it. Thanks!

As for how it could change, imagine that the container is a horizontal 
panel ... one of those things with the border that you can grab with a 
mouse and move left or right. So, the user could change that GtkImage 
dimension. Actually, that reminds me that not only do I need to know when 
the size has changed, but I also need to be able to veto it if it gets too 
small.

Still, you got me part way, I think ... thanks!

... anyone else??????
