Detailed Description

Animates changes fading the new UI over the old look.

This widget will put itself above the widget that will change and show a fading transition from the old to the new UI. It will delete itself after the animation is finished. Example:

KFadeWidgetEffect *animation = new KFadeWidgetEffect(widgetThatWillChange);
// do changes on widgetThatWillChange
// ...
animation->start();

Note

The widget that changes needs to have a parent widget. KFadeWidgetEffect does not work for toplevel widgets (windows).
