Hello Koen! Please let me describe my use case, below. But before I do, let me emphasize that this is just a learning experience for me, so let me make clear that my use case is not important, and is really just an exercise I picked pretty much at random.

Let's say that I have two WPushButtons, one on the left, and one on the right. The one on the left is labelled "Hello" and the one on the right, "Goodbye". I wish to animateHide both buttons, change the left text to "Goodbye" and the right text to "Hello", and then animateShow the two buttons. Roughly speaking, I wish to swap the two buttons with some animation eye candy. (Again, this is all just for fun.) When I try the above, the animations don't appear -- the text on the two buttons changes immediately. I will note that in this experiment the two WPushButtons are "inline" widgets. That is (referring to my other thread on animation) I have not called "button_->setInline (false);" Another detail: In one version of the experiment I did call "button_->setHiddenKeepsGeometry (true);" on both buttons so that the location of the one button wouldn't change when the other button was being hidden. This was an attempt to avoid having the changing location of a button confuse its animation. Any pointers -- for this unimportant practice project -- would be greatly appreciated. Thanks. K.
