Event handler for all commands

[weissgeorg33]

I am trying to use Python script and attach an event handler to all Fusion commands, which would count invoked commands in my Fusion session. Is it possible to use this event? What will be the "command_var"?

onActivate = MyActivateHandler()
command_var.activate.add(onActivate)
handlers.append(onActivate)

Hi @weissgeorg33 -san.

I understand that you want to count all commands invoked.

In Fusion360, the command is called for almost every operation.
Therefore, the “UserInterface.commandStarting” event is fired.

The event handler receives “ApplicationCommandEventArgs” as an argument.

The ApplicationCommandEventArgs object has a commandId property.

In other words, it can tell what command was invoked.

By creating a dictionary with CommandID as a key and counting it, you can keep track of what commands the user has used and how many times.
