System.int SuspendSelectionList()

System.int SuspendSelectionList(); 

Return Value

To add objects to a selection list without preselecting the objects in the user interface:

1. Call ISelectionMgr::SuspendSelectionList to suspend the current selection list, preserving its contents and starting a new selection list.
2. Call ISelectionMgr::AddSelectionListObject or ISelectionMgr::AddSelectionListObjects to populate the new selection list.
3. Process the objects in the new selection list.
4. Call ISelectionMgr::ResumeSelectionList to reinstate the suspended selection list.

To programmatically preselect objects in the user interface and add them to a selection list, use IModelDocExtension::SelectByID2.

IModelDoc2::ClearSelection2 works like ISelectionMgr::SuspendSelectionList to clear the selection list. Unlike IModelDoc2::ClearSelection2, this method preserves the list for future reinstatement.
