[vtk-developers] Overriding MouseButtonPressEvent in vtkChartXY

[Brad Hollister]

Hi,

I'd like to override the mouse handler for vtkChartXY in Python. 
However, when I do this, the overriden function is not called. I have 
the following:

from vtk import vtkChartXY, vtkContextMouseEvent

class dbsTransFuncChart(vtkChartXY):
     def __init__(self, parent =  None):
         vtkChartXY.__init__(self)
         self.par = parent

     def MouseButtonPressEvent(self, *args, **kwargs):
         self.par.updateRenderQVTKWin()
         return vtkChartXY.MouseButtonPressEvent(self, *args, 
**kwargs)
   

Is there a way to do this properly?

Regards,
Brad
