Tooltip API?

[MattKincaid]

When you mouse over elements in the model, Revit displays a tool tip with info about the element.  Is there an API to modify the contents of this?  See image, attached.

If not, anyone found a good way to write your own?  Thanks!

I do not believe the Revit API offers any functionality in this area.

You can create your own tooltips beside Revit's, which is probably not very useful:

The other option would be to use the native Windows API or a .NET library to modify the Revit ones.

Kean Walmsley implemented something to translate tooltips:
