Hooks for Properties Panel Edits?

Revit API

I was looking at the anatomy of hooks

to see if there is one for when a user clicks in a field like Comments, it would trigger something

I’m trying to explore if I can make a pop up text editor when users click in text parameter fields so that we can see all the text in a nice wrapped window.

The 2026 Revit API provides access to these events:

UI Application Events

Application Class Events

Controlled Application Events

No event specific to the property panel per se.
But in itself, this is a Transaction, The Document is Changed, so you could piggy back on the DocumentChanged event for example:

The idling event is another option, but may overload Revit
