[Qt-interest] Catch QTabWidget change event before change

[Matthias Paul]

Hello David,

my fault.

It's a QTabWidget I currently use, not a QTabPane or QTabBar. I should not post too early in the morning :/

Still, the problem remains: I'd like to fetch the tab change event before the change takes place (and will be visible to the user).

Thank you,
Paule
