The IVsUIHierarchy type exposes the following members.

Methods

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