ROI handle size

[Peter Ercius]

The ROI (and all sub classes) have a hard coded handleSize attribute set to 5 (pixels?). See here.

This is very small for large monitors and large images. I have not found a way to change this without class inheritance and overwriting the addHandle() function.

Is there a way to simply set the handleSize and then redraw the ROI?

Hey Peter,

Yeah, that is often pretty small.You can update the existing handles with:

for handle in roi.getHandles():
    handle.radius = 10
    handle.buildPath()

    handle.update()

That is exactly what I was looking for. Thanks for the quick response!
