Draw on a QTableWidget

[Corran]

I'm letting Qt call the event whenever it wants to. It seems to do it whenever a cell is selected or deselected and when it is moved. The function is definitely being called though.

I can even reproduce the problem in a minimal program where the only thing I do is create the custom table and try to draw in it's paintEvent function.

From http://doc.trolltech.com/4.1/qabstra...tml#paintEvent

void QAbstractScrollArea:aintEvent ( QPaintEvent * event ) [virtual protected]

This event handler can be reimplemented in a subclass to receive paint events (passed in event), for the viewport() widget.

Note: If you open a painter, make sure to open it on the viewport().

Reimplemented from QWidget.

See also QWidget:aintEvent().

Maybe this helps

That sorted it, thanks a lot. I'd only read the QWidget paintEvent documentation. It didn't occur to me that it would be subclassed halfway through the system like that.
