Review request for KDE Frameworks, Christoph Feck and Aurélien Gâteau.


Repository: kwidgetsaddons


Description
-------

Hi, I've found that if you call animatedShow() immediatly after animatedHide(), without waiting for the hide animation to finish first, the hide animation goes on and, in the end, the message widget becomes hidden.

The attached patch adds checks in animatedShow and animatedHide so that, if an opposite animation is currently running, they just reverse it.

Testing
-------

I've added buttons to invoke animatedShow and animatedHide in tests/kmessagewidget.cpp and used them to test the behavior.

I've also added an autotest that checks the final height and isVisible() value, both after single animatedShow/animatedHide calls and after animatedShow+animatedHide and animatedHide+animatedShow.


Thanks,

Fabio D'Urso
