Re^4: Tk: Scaling canvas objects

That fix works for me too! Thanks! =D

Sorry, but I don't think I understand why this is necessary. Why didn't I have this problem when I had the whole thing running out of a single file?

Thanks,
Perldough

I'm not sure why it works in a monolithic script, but not in your modules. It must have something to do with how the Scrolled widget works, and your module's @ISA. This is not the only time you will encounter this with Scrolled Canveses or Text widgets. Most of the Scrolled widget's internals get passed on, but some don't. The most notable of these is using Balloons on Scrolled widgets.... you most often need to bind to the actual Subwidget, the Scrolled widget is finicky. By the way, if you are serious about zooming, rotating, and scaling on a Canvas, you should look at Tk::Zinc, it still works well even if it isn't being maintained.
