How to lock a widget height and width?

Question

I want to lock a widget height and width but the UI for that seems to no be working. What am I doing incorrectly?

I tried this lock in the image and it doesnt seem like its doing anything:

Or is it possible to get the height and width programmatically? Any help will be greatly appreciated.

It works as expected for me.  It preserves the aspect ratio of the image in the image widget, for example.  The Height changes to Auto, and the Height is automatically updated when I change the Width.  Were you wanting it to have a different effect when you locked it?
