[Ruzik]

Hi Ruzik, have you got Q_OBJECT in your QMainWindow or child of QDockWidget? If yes then you need to rewrite paintEvent. Try documentation, there was an example how to do it.

Class is the child of QDockWidget, please help me with rewrite:
I write in class:
protected:
void paintEvent ( QPaintEvent * event );
And in cpp file
void Search::paintEvent ( QPaintEvent * event )
{
this->repaint();
}
And an error of unhandled exception
Error on this line-> this->repaint();
I find information in assist, but i dont foind anythink
P.S. Thank you very much for your attention

Hi Ruzik, I am sorry for long response and here is the code for paintEvent:

@void Search::paintEvent(QPaintEvent *)
{
QStylePainter barPainter(this);
QStyleOption barOption;
barOption.initFrom(this);
barPainter.drawPrimitive(QStyle::PE_Widget, barOption);
}@

It should be done with all Widgets that have Q_OBJECT and you want to use stylesheet with them, it was somewhere in the documentation but this stylesheet section is really messy and I can't find it anymore. Hopefully it works.
