[Paraview-developers] Paraview error related to click event

[Prashant V]

Hello,

I have developed a source plugin which renders vtkMultiBlockDataSet. Recently, I noticed an issue while running Paraview in parallel mode.

While running Paraview in parallel, my source plugin renders vtkMultiBlockDataSet. Then I select 'Plot Data' filter and hit apply button. This splits Paraview screen and creates a new window to display plots. I select geometry and parameter(s) and plots are drawn in 'Plot Data' filter window. At this point, focus is on 'Plot Data' window. Now as I click on other Paraview screen window containing vtkMultiBlockDataSet, somehow my source plugin's RequestData() method is called.

This behavior is not observed in serial run of Paraview. Any pointer towards this strange behavior?

Also I am curious to know which function in Paraview is invoked when we click on Paraview screen to change focus?

Highly appreciate any help in this regard.

Thanks,
Prashant
