Some how-to's for a few Qt cool features

LabelPixmapAnimator

Some examples of how to animate some QPixMap objects. Examples shown here consist of rotating a simple png image contained within a QLabel. Principle can easily be extended to other features.

Note: To create an animation that only interract on basic properties of a widget (such as position or size), you may rather consider QPropertyAnimator class.

Available examples are:

1. Constant animation: Image rotates smoothly at constant speed.
2. Animation with predefined profile: Speed follows a predefined profile for speed. There are several profiles available in Qt.
3. Custom animation: Equation for animation computation is user-defined. Example shown here is a non linear movement.
