Hi, I'm not completely familiar with the working of the flowchart, but believe it is still based on GraphicsItem/GraphicsScene like the rest of pyqtgraph. The trick then is that it is all based off Qt's QGraphicsItem/QGraphicsScene etc. So, looking at http://www.pyqtgraph.org/documentation/_modules/pyqtgraph/GraphicsScene/GraphicsScene.html#GraphicsScene I think the event hit boxes come from calling the shape() method inherited from QGraphicsItem (https://doc.qt.io/qt-5/qgraphicsitem.html#shape), which by default just returns the bounding rectangle. So you could try looking at the examples in the Qt documents about how to return something different from the shape() method and override it in your custom Node/NodeGraphicsItem.
Hope that helps, Patrick On Thursday, 30 January 2020 10:08:25 UTC+10:30, Patrick Singh wrote: > > Hello there, > > I am currently working on introducing different kind of nodes to the > flowchart.
