TabControl in VW7.2

Hi all,
I'm trying to use a TabControl widget using subcanvas as showed in the
TabControl example, but I get lot of errors because it seem not possible
to use, as subcanvas, something a bit more complex than a Text widget or
similar.

In particular I'm not able to get a properly configured List widget menu
(I get a 'message not understood #menuAt:' because the builder of the
subapplication is nil when i try to open the app; I have also problems
nesting two TabControl (Text widgets disappear from the nested tabs....)

I tryed to figure out how to rebuild the subcanvas each time a tab is
selected (because I think the problem is related to the builder of the
subcanvas) but without success.

Any help would be very very appreciated

Thanks
Luc

I've had heavy problems with sub-builders and nested TabControls in VW and
ended up in writing my own UI extensions. Considering the price tag of VW,
it's a little too much work to get a state-of-the-art UI up and running.
However, there are some other nice features compensating for that. I hope
Pollock will change this.

I'm afraid my extensions won't help you much, because I'm using some
non-standard procedures (PluggableAdaptors in conjunction with simple
accessors to the ApplicationModel). If you like I could send you the classes
(though this will require you to do some heavy fiddling with your code).

at least I can stop scratching my head trying to find bugs in my classes.

It's not really a good new to hear because this will drive me to a
complete rewriting of the UI, but will find a solution.

BTW I'd like to see your classes, maybe I'll find some useful hints..

thanks
