New thread to handle paintEvent

[bitChanger]

I have a Qt GUI that contains a widget that plots data. The plots are being update and repainted so often that the main GUI thread is sluggish. Can I get a new QThread to handle the paintEvent of a QWidget?

Perhaps you could draw less? Did you try tweaking the widget attributes?

Unfortunately not, but you can draw on a QImage.
