[Ctk-developers] Setting name and description of ctkWorkflowWidgetStep

[Danielle Pace]

Hi Daniel,

Actually, I think you exposed something important here.

I'm assuming, from python, that you wrote something similar to:

- create step 1 (with no name/description)
- create step 2 (with no name/description)
- create workflow widget and add steps
- display workflow widget
- set name/description for steps 1 and 2
- expected to see workflow update, and it didn't

Is this correct?  I think we are missing some signals on ctkWorkflowStep
such as NameChanged(QString) and DescriptionChanged(QString) that the
ctkWorkflowGroupBox should be listening to.

Perhaps you could still post your snippet of python code that wasn't
working, so I can verify that it is an ordering of commands that we should
support?

Thanks,

Danielle
