Hi,
I don't totally understand all of the pyqtgraph GraphicsScene
modifications, but you're right that the usual things you'd do for a
QGraphicsScene don't seem to work.
Here's a crude way to disable mouse interactions, by live patching the
legend mouse handler methods. I'm 99% sure this isn't the best way to do
it, but it works.
# Crude patch of the legend mouse methods
import types
def nullifyEvent(self, ev):
return None
self.legend.hoverEvent = types.MethodType(nullifyEvent, self.legend)
self.legend.mouseDragEvent = types.MethodType(nullifyEvent, self.legend)
