Hi Justus,
a workaround would be to set sensitive=0 on all the other child bases
of the widget_tab. This won't prevent you from tabbing to those tabs,
it just prevents you from doing anything once you get there. It's a
clumsy workaround, especially if you want to let the user know why
they're not allowed to do anything in the other tabs - maybe a tooltip
on desensitized buttons ('Finish work in Tab0 first!') would work. I
agree it makes both the code and the GUI messy.
One other thing you might think of is to create a new modal tlb whose
group_leader is the relevant child base of the widget_tab. I don't
really like the "2-GUI" effect this gives, but it would also work.
If there's a better way of doing it, I'd love to hear it!
Regards,
Chris
