When the hierarchy window has focus, any commands that you implement are sent to the hierarchy window instead of to the standard command-handling interface, IOleCommandTarget, which does not support hierarchies. IVsUIHierarchy is similar to IOleCommandTarget in terms of functionality, but also provides information about the item that is currently selected in the hierarchy, based on the value of VSITEMID.

Commands that you want to use from outside of the hierarchy window, such as adding a project item, should not be handled by the IVsUIHierarchy methods. Only use the IVsUIHierarchy interface to handle the following types of commands:

  • Commands that require the UI Hierarchy window to have focus.

  • Commands that act on a specific item within the hierarchy. (If ItemID equals VSITEMID_SELECTION, the command is applied to the selected item or items.)

Handle all other commands related to the active hierarchy with the IOleCommandTarget interface.

Tool tips in a UI hierarchy window are reserved to show the full caption of the node if the caption is being clipped by the current view (i.e. the window is too narrow to show the full caption). You can not provide custom tool tips for UI hierarchy windows.

Notes to Implementers

Implemented by VSPackage writers to handle commands such as Cut, Copy, Paste, Delete, and Rename sent to the hierarchy window.
