Problem with transform of pointer
I have parent class and widget, and in class of this widget i write
@ RizekColorManager * rcm;
rcm = qobject_cast<RizekColorManager*>(parent());
There no some mistakes, but there are doesnt work, why?
Advance thanks for your help!
Are you sure that parent of your widget is RizekColorManager instance?
RizekColorManager has to derive or indirectly derive from QObject and must also have the Q_Object macro according to Qt Assistant.
For a widget, parent has to be a widget. The problem is probably that the parent widget is not actually the expected RizekColorManager.
Many thanks for your help, I did not consider object CentralWidget
