Animating "any" widget?!?

**nupul** · 8th April 2006, 04:55

Qt4 is equipped with a powerful paint engine. Now can widgets like Buttons, Custom widgets and as well the whole widget window be animated??

eg:
1. Button rotating when clicked,
2. Widget's top level window shearing on minimization etc...

What are the limitations of Animations in Qt4?

Thanks.

You could adapt some ideas from Qt sources: src/gui/widgets/qeffects.*
There isn't rotation, but fading and scrolling, though. But after understanding the principles used in QEffects (which is a private class of Qt), it shouldn't be too hard to implement a rotating effect..

It's a private Qt class which is not intended to be used.

Check inside the installation package
qt-x11-*-src-4.1.2.tar.gz: qt-x11-*-src-4.1.2\src\gui\widgets
