Changes for version 1.10
- Bug reported via c.l.p.tk [Tk::JComboBox Question - http://groups.google.com/group/comp.lang.perl.tk/msg/2971450102b53533 textvariable option not working correctly: when set, a default value *does* appear in the JCombobox Entry, however once the Button is pressed, it does not appear selected (or scrolled to) within the Listbox. This occcurs when the Button is pushed once. If pressed again the item does show as selected.
- The problem: Because I wasn't a big fan of the option, I implemented it in an overly simplistic way, by delegating it to the Entry widget. This meant that it if the variable was assigned a value, then it would appear within the Entry widget, but the rest of the JComboBox code would not necessarily be aware of it. There was code that was "set" the value as selected when the Popup Listbox was closed, but not when it was triggered.
- The solution: I tried two different solutions, the one I decided to go with was what I probably should have done orginally which was tie the textvariable to JComboBox code, so that stores/fetches were tied to JComboBox methods, and there was some measure of consistancy in the implementation. For example, before if the JComboBox was in readonly mode, you could use -textvariable to set a value that didn't appear within the Listbox, which broke the basic model of the mode. I used Steve Lidie's Tie::Watch class to implement the fix.
- Docs and Test cases were updated to reflect the modifications, and I did some more proofreading on JComboBox.pod to remove typos and a few inaccuracies.
