'lo all...

I've only done a little programming with Perl/Tk, although I've been programming with perl for quite a while. Hence, I'm having a little trouble with the 'event-driven' thing.

The attached code does what it does... but instead of clicking the "Pop It!" button to bring up the popup window, I actually want the sequence of things to be more like:

- setup the main window

- click the "Pop It!" button and call 'AddItem'

- once in AddItem, I want the popup to be displayed, and to stay there whilst I do things in 'AddItem'. Once 'AddItem' is more-or-less done, the popup is removed (like when the button is pressed) and we're back in the main window.

The popup is like a 'status' window... but I'm not sure how to actually -do it-... It's simple enough to do things with a button action but this is where I get confused with the 'event-driven' thing.

I'd appreciate any pointers...

Thanks.
