Hi, ROI objects inherits from GraphicsObject which also inherits from QGraphicsObject (and all ROI objects in pyqtgraph such as rectangle and polyline for example inherits from ROI). You should be able to overwrite the appropriate class and reimplements the paint method to 'fill' to form. That should work, but there may have cleaner way to solve your problems. Other ideas?
