Remarks
The SelectionContainer class provides a unified interface for accessing a set of selected objects. It implements all of the methods defined by the ISelectionContainer interface, and adds a new method, ActivateObjects, that enables an object to respond when selected.
Typically, the contents of the selection container are modified by an external object calling SelectObjects(UInt32, array<Object[], UInt32), which triggers a SelectedObjectsChanged event (and can also call the ActivateObjects method, if it is implemented.) The contents of the selection container can also be examined or changed by accessing the SelectedObjects or SelectableObjects methods.
When changes occur that affect the Properties window, the VSPackage must alert the environment by calling the OnSelectChange method with the SelectionContainer object that reflects the current selection context. The environment then makes calls to the SelectionContainer methods to retrieve one or more IDispatch objects, which provide access to the data needed to update the Properties window.
The SelectionContainer class also simplifies some interoperability issues with the ISelectionContainer interfaces. Different versions of Visual Studio implement different versions of ISelectionContainer, and SelectionContainer provides seamless interoperability with the different implementations.
Notes to Implementers
A selection container is the mechanism used by windows to push information to the Properties window. A VSPackage should include a SelectionContainer object for each object (typically a window) that contains selectable objects with related properties to be displayed in the Properties window.
