MaxCustomControls::MaxTreeListHandler Class Reference

---

Detailed Description

Overrides a lot of the DevExpress standard behaviour with custom behaviour.

The DevExpress.TreeList class allows the client to supply its own handling class to override the behaviour in specific situations. We take advantage of this fact. The DevExpress TreeListHandler handles mouse operations for the TreeList using a set of TreeListState classes. This MaxTreeListHandler overrides TreeListHandler to supply custom states adjusting interaction to our specifications.
