Today I've finally written my first example with the Qt Animation Framework (Qt 4.6).
The animation framework aims to provide an easy way for creating animated and smooth GUI's. By animating Qt properties, the framework provides great freedom for animating widgets and other QObjects.
The examples is really simple, few lines of code. And the Qt Animation Framework does all the magic under the hood. Just assign the Start and the End Value for the specified property and the interpolator does the rest.
