Command type in python

[carlopav]

I'd like to use the command manager addCommand() to produce a checkable toolbar button in python.
Is there any documentation to do it automagically passing some extra arguments to addCommand?

Edit: something like Std_TreeSyncView

AFAIK the Draft snap tools do what you look for and they are done in Python AFAIK.

The Draft toolbars are kinda "non standard"ncause they are added and controller directly by Draft wb.
I was asking myself if there Is an option to produce a checkable QtAction when adding a command, to reduce code duplication...
