The IVsUIHierarchy type exposes the following members.

Methods

	Name	Description
	AdviseHierarchyEvents	Allows clients to hook up for event notifications without making the hierarchy implement IConnectionPointContainer.
	Close	Closes and cleans up a hierarchy once the environment determines that it is no longer used.
	ExecCommand	Executes a command on a specific item within a UI hierarchy window, or on the hierarchy itself.
	GetCanonicalName	Used for workspace persistence, for example, for remembering window positions.
	GetGuidProperty	Identifies the "type" of a particular node.
	GetNestedHierarchy	Makes it possible for a node of a given hierarchy to be a shortcut to the middle of another hierarchy.
	GetProperty	Gets properties of a given node or of the hierarchy.
	GetSite	Gets the service provider from which to access the services.
	ParseCanonicalName	Returns the identifier of the hierarchy item, given its canonical name.
	QueryClose	Determines whether the given hierarchy can be closed.
	QueryStatusCommand	Queries the object for the command status.
	SetGuidProperty	Sets properties whose values are GUIDs.
	SetProperty	Sets properties of a specific node or of the hierarchy.
	SetSite	Sets the service provider from which to access the services.
	UnadviseHierarchyEvents	Disables client notification of hierarchy events without requiring that the hierarchy implement IConnectionPointContainer.
	Unused0	Unused. Return E_NOTIMPL.
	Unused1	Unused. Return E_NOTIMPL.
	Unused2	Unused. Return E_NOTIMPL.
	Unused3	Unused. Return E_NOTIMPL.
	Unused4	Unused. Return E_NOTIMPL.

Remarks

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.
