[Qt-interest] Animation QPushButton size?

[Wilhelm]

Hi all,

I'm trying to animate the size of a QPushButton, which is part of a 
QGridLayout. The animation is part of QSignalTransition.

If I modify the "size" property from the initial size of the button, 
scale it down and at end scale it to the original size again,  I get an 
overlapping with other elements in the grid-layout at the end of the 
animation. The problem vanishes, if I call update() on the layout when 
the animation finishes.

But I think, this is not the right way!
Any hints to do such size-Animation inside layouts?
