onCopy event in hda

[sanostol]

how can I trigger a event, when a node gets copied?

thanks

There is no copy/paste event, which is lame, I RFE that a while ago, but you can workaround this with OnNameChanged event. Print the kwargs args and see the difference between duplicating a node and just renaming, it's a little bit tricky though. I don't have a code with me now.

ah, there is a difference, I will try, thanks a lot.

PS: a bunch of more events would be really cool

HI, I know this is an old thread,

could anyone shed some light on this?

I need to have my custom function track if the HDA has been duplicated?

What is the best practice.

 

Cheers

def is_copy_paste_event(kwargs):
    if not kwargs['node'].name().startswith('original') and not kwargs['old_name'].startswith('original'):
        original_node = kwargs['node'].parent().node('original0_of_%s' % kwargs['old_name'])
        return True if original_node else False

 

Use this in an OnNameChanged event handler

Thank you so much for this Alex.

 

been banging my head against the wall in a code hole. does not help when I am no Python wizard.

 

Cheers again
