Hello,
I would need to execute some code when an instance of a widget is created and destructed.
For creation I mean when a widget is dragged in a sidebar in the Widget admin page.
For destruction I mean when the widget is deleted form the same sidebar.
I was not able to find any suitable action hooks, so I was wandering if it is something that should be added or if I am approaching the problem in a wrong way.
If needed I can provide more details, thanks in advance.
What exactly are you trying to fire and why?

First of all, I am subclassing the WP_Widget class.
The widget must support multiple instances.
Each instance needs to store(for caching purposes) some data in a subdirectory like this: <plugindir>/cache/instance-<n>.
So, I need to create and remove this directories and I was thinking that the most natural event would be when the user drag a new widget instance on the sidebar and when he clicks the delete link.
I understand that i could create the subfolder in the overriden WP_Widget::update() method but it is not elegant (nor efficient).
And what about the directory removal? How to catch this event?
I hope I've been clear, sorry for my english.
