[vtkusers] Interacting with visualisation pipeline execution - MessageBox

[John Platt]

Hi users,

 

In my naivety, I displayed a MessageBox during the Execute() method of a
filter I was modifying. As the MessageBox is dragged, the render window
receives paint messages and presumably responds by trying to execute the
pipeline. I thought the pipeline execution would be blocked by the
MessageBox however the window still repaired. Can anybody explain? (I
did get a generous helping of error messages!)

 

Is there a way to interact with the pipeline execution in such away, for
example, continue/abort?

 

Many thanks

 

John.
