Detailed Description

Compability class.

This class provides a compability function for asyncronous updating of a QWidget. As QWidget::update() has shown to be not as threadsafe as expected, the new updateFromOtherThread function fixes this problem.

updateFromOtherThread used QApplication::postEvent, to post a UserType QEvent to this object, which is caught in the overloaded event() function
