Welcome,

Anyway there's a very nice event called "OnHint".
You can query mouse position with TMouse.CursorPos and
GetItemAt method of TreeVeiw checking to see if it's pointing to a
tree node.

Now, simply do a TextWidth on the canvas and compare with the
client width, adjusting for the origin - which can be taken I think in
some way.

You have all the elements then to show the hint.

Obviously, if Bruno has implemented all this directly inside the
treeview component, the better.
