[vtkusers] Invoking a User Calback

[Andy Treisch]

Hello!

I have a problem Invoking a user callback command in my pipeline.

I initialize and start my pipeline in a thread with the usual stuff
ending up in

vtkCallback* callback = vtkCallback::New();
callback->SetCallback(updateFieldData);
vtkRenderWindowInteractor* iren = vtkRenderWindowInteractor::New();
iren->SetRenderWindow(renWin);
iren->AddObserver(vtkCommand::UserEvent+1, callback, 1.0);
iren->Initialize();
iren->Start();

The Callback function updateFieldData should be invoked when I send
vtkCommand::UserEvent+1 message to the Interactor. Now I try to

iren->InvokeEvent(vtkCommand::UserEvent+1)

in another function of my application, but that does not work. My
application never reaches the updateFieldData function although
the InvokeEvent line is executed.

How do I invoke my event?


Thanks in advance for your help,
