Summary

Specifies a menu that is used as the items of the tree view.

Pascal

 propertyMenu: TMenu;

Description

Assign a TMenu (or a descendant, like TMainMenu or TPopupMenu) to the Menu property of the control to make the tree view use the menu's items for its structure.
When a menu is assigned, clicking a node in the tree view has the same effect as clicking the menu item itself (see MenuDblClick for details).
Only menu items with valid captions (all captions except '-' and ) are added to the tree view.

About

Notes

TJvTreeView replaces the OnChange event of the assigned TMenu to be notified about changes in the menu's structure. The original OnChange vent is called automatically (if assigned). If you need to replace the menu's OnChange event at run-time, you should first set Menu to nil, replace the OnChange event and reset the Menu property to its previous value.
Failing to do so can cause errors and even Access Violation exceptions in your program.
