Review request for kdelibs.


Also scroll on TabWidget empty space.


KTabWidget implements tab switching as response to mouse wheel events. This makes applications like Rekonq, that use a KTabBar instead, do nothing when the wheel is scrolled.

The proposed patch moves the behaviour implementation from KTabWidget to
KTabBar, disables and disconnects the relevant signal in KTabBar/KTabWidget.

Note that QTabBar in Qt already implements this with a small difference: it
does not wrap around the extreme tabs. That is, it will not go from the last to
the first tab and viceversa.

This addresses bug 248962.

Rekonq works as expected.
KTabWidget users, such as Konqueror and Konsole work as well.
