Create a Clock Attribute Like Measure Menu

When designing a Python Add-on, how do I create a click-through property like the Measure menu option, as shown in the following figure?

In addition to the help files, do we have a more detailed and richer tutorial on Add-on?

With Python you can add properties to a command that are supported and those are mostly the same as for a component e.g. VC_STRING (str) , VC_BOOLEAN (bool), VC_INTEGER (int) etc.

Only the properties of a command are shown in the action panel which in turn means that the drop-down (expandable) sections are not supported nor the radio buttons.

It should be possible with .NET only.

P.S And please use the correct section of the forum. This post is related to Python and therefore moved here.

 

Ok, thank you.
