* In its current form QToolTip is not extensible. So this is an attempt to provide a more
|
|
* flexible and customizable tooltip mechanism for Creator. Part of the code here is duplicated
|
|
* 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.
