Hello, I'm attempting to implement an action based on sigMouseMoved, but have got seriously confused about how to access this signal.
*The Project* I am creating multi-panel plots inside a larger pyqt application. To do this, I have contained everything within a GraphicsView, which contains a central GraphicsLayout that contains the plots. I am using PlotItem to create plots, which I then add to the GraphicsLayout using addItem. This is all working fine, and I end up with two plots displayed - let's call them Plot1 and Plot2. Now, I want to display the cursor position in a label, so I created a label and a mouseMoved function to update the label text. *The problem: I can't work out how to connect sigMouseMoved to my mouseMoved function.* Following the documentation and examples, I tried setting up a SignalProxy: SignalProxy(Plot1.scene().sigMouseMoved, rateLimit=60, slot=mouseMoved) When I try to run this, I get an AttributeError telling me that 'NoneType' object has no attribute 'sigMouseMoved'. I can't work out why calling scene() on my plots returns None! The only difference I can see from the examples is that I'm manually creating 'PlotItem' rather than pyqtgraph.plot to create my plots... but as far as I can tell the .plot function is just a wrapper for creating a PlotItem. Any help/pointers would be greatly appreciated... this is driving me mad! Thanks, Oscar. -- You received this message because you are subscribed to the Google Groups "pyqtgraph" group.
