Time Limit for MSG_DESCRIPTION_CHECKUPDATE

Hello PluginCafe!

I need to apply SetDirty() function only after finishing the manipulation process of the desired parameter.

Something like this is implemented in the material preview.
The update takes place only after ~0.5 seconds after finishing the manipulation.

So, I tried to check updates via MSG_DESCRIPTION_CHECKUPDATE and calculate the time by utilizing timeit module

'''

        start = timeit.default_timer() #Start Timer

        if type == c4d.MSG_DESCRIPTION_CHECKUPDATE: 

            if data["descid"][0].id == TEST_SLIDER: #Check if TEST_SLIDERis updated
                
                end = timeit.default_timer() #End Timer
                    if end - start > 1: #Do something if time took more than 1 sec
                        self.bmp.SetDirty()
                        node.SetDirty(c4d.DIRTYFLAGS_DATA)

But unfortunately, I can't find the solution in the documentation.

What am I doing wrong and how to do this properly?

Hello,

you could react to the message MSG_DESCRIPTION_USERINTERACTION_END which is sent after the user stopped interacting with the parameter in the Attribute Manager.

You find a list of related messages in the NodeData::Message() Manual.

Is this feature available for Python?

Nice it works with python but how to check only one parameter instead of everything?

something like this

        if type == c4d.MSG_DESCRIPTION_USERINTERACTION_END:
            if data["descid"][0].id == TEST_SLIDER: 
                print "Finished"

Hello,

the message MSG_DESCRIPTION_USERINTERACTION_END has no data. You could store the old value of the parameter in question and check if that value has changed.
