cliNode = slicer.cli.run() returns a vtkMRMLCommandLineModuleNode that can asynchronously call a CLI module.
It is shown here that one can use the
cliNode.AddObserver() callback for when the “cliNode is modified”.
I was unable to find any documentation on what this means exactly? When I print the output of the callback I get a lot of events. But the only unique
caller.GetStatus():caller.GetStatusString() values are “2:Running” or “32:Completed”. So why is the callback called so many times if the modification of the CLI module takes place only twice.
This is not a blocker to my work and I was just curious since I was unable to find documentation around it.
