* from QToolTip. This includes a private Qt header and the non-exported class QTipLabel, which
* here serves as a base tip class. Please notice that Qt relies on this particular class name in
* order to correctly apply the native styles for tooltips. Therefore the QTipLabel name should
* not be changed.
