DisableCommand using IExternalApplication

1

Is it possible to disable a command similar to the SDK sample? I tried converting to python but not working. The command is still available. I’ve seen an example of IFamilyLoadOptions in python so wondered if it was possible w/this interface. Thanks


class Application(UI.IExternalApplication):

    #s_commandId = "ID_FILE_IMPORT"
    s_commandId = "ID_EDIT_DESIGNOPTIONS"
    
    # Implements the OnStartup event
    def OnStartup(self, application):
        
        # Lookup the desired command by name
        s_commandId = UI.RevitCommandId.LookupCommandId(self.s_commandId)
        
        # Confirm that the command can be overriden
        if not s_commandId.CanHaveBinding:
            self.ShowDialog("Error", "The target command " + self.s_commandId + " selected for disabling cannot be overridden")
            return UI.Result.Failed

        # Create a binding to override the command.
        # Note that you could also implement .CanExecute to override the accessibiliy of the command.
        # Doing so would allow the command to be grayed out permanently or selectively, however, 
        # no feedback would be available to the user about why the command is grayed out.
        try:
            commandBinding = application.CreateAddInCommandBinding(s_commandId)
            commandBinding.Executed += self.DisableEvent
        except:
            self.ShowDialog("Error", "This add-in is unable to disable the target command " + self.s_commandId + "; most likely another add-in has overridden this command.")

        return UI.Result.Succeeded
                            
    # Implements the OnShutdown event
    def OnShutdown(self, application):
        s_commandId = UI.RevitCommandId.LookupCommandId(self.s_commandId)

        # Remove the command binding on shutdown
        if s_commandId.HasBinding:
            application.RemoveAddInCommandBinding(s_commandId)
        return UI.Result.Succeeded

    # A command execution method which disables any command it is applied to (with a user-visible message).
    def DisableEvent(self, sender, args):
        self.ShowDialog("Disabled", "Use of this command has been disabled man.")

    # Show the user a message
    def ShowDialog(title, message):
        td = UI.TaskDialog(title)
        td.MainInstruction = message
        td.TitleAutoPrefix = False
        td.Show()

    #Do some action in a Transaction
TransactionManager.Instance.EnsureInTransaction(doc)

myApp = Application()
OUT = myApp

TransactionManager.Instance.TransactionTaskDone()
