Currently (v2.10) we don't have a way to detect if a search has performed for a Tree View control through a Edit control (idcSearch) unless we try to check the tree for every frame.
Since the search won't be performed ASAP when we enter words in the Edit but few frames late, it also is impossible to detect even if we try to detect through onChar or some EH.
Possible values for it:
- Control - The tree control
- Search Control - The edit control
- Search word - The edit's text, the words for the performed search
