[Qt-interest] painting on a widget

[Darryl Hunter]

Hi all,

 

I have a widget that has several layouts / widgets displayed on it.  All is
good.

 

Under a certain circumstance I want to draw a circle on the widget on top of
everything else.  So in my widgets paintEvent() method I do:

QPainter painter

painter.begin (this);

helper->paint (&painter, event);

painter.end

 

Within my Helper::paint() method, I do:

painter->drawEllipse (.).

 

However it draws this ellipse behind the other components of the widget.  I
want it to be in front of.

 

With the Graphics Scene there is a Z value which would take care of this.
How do I do this with the normal painter?

 

Thanks.

 

Darryl
