Hook to TOC selection change event

[DavidLednik]

How do I hook to selection change event (or OnMouseDown) of ArcMap TOC from a custom plugin.
I have a plugin that has an extension and dockable window and I need to update the window with information every time you select a new layer in TOC. Is this even possible?

I don't think there's any way to listen for the actual event.  One solution would be to put a timer on your dockable window that would fire every second or so and get the selected item from the TOC contents view.

That's what I'm doing now 😉

I put together an example showing how to subclass the SysTreeView32 (TOC) and listening to selection change events:
