ufe.SelectionChanged() usage to track selected USD prims

[riga_rig]

Hi!

I use "SelectionChanged" event callback to add items to PySide ComboBox.

It works quite good for native Maya objects, but unfortunately doesn't work for USD prims.

What is a proper way to create something like SelectionChanged callback for USD primitives? Is ufe.SelectionChanged() class could work for this?

Regards,

Oleg Solovjov

There is also a "UFESelectionChanged" event that you can use in
scriptJob's. Have you tried that?

I spend some time with Autodesk UFE documentation and found that SelectionChanged is a subclass from Notification class.

It should work as a subscriber in Observer design pattern. There is also ufe.Observer class and ufe.ObserverSelection classes.

Could anybody point me to documentation or example snippet, 

how I should configure those classes to implement SelectionChanged event for USD prims in Maya?

Thank you Tim!

I just read all scriptJob command documentation and can't believe I overlooked it.

I would test it right now.

It works as needed with scriptJob and with OpenMaya.EventMessage! Thank you Tim once more!
