Communicating with a Tree Control

Home |  Overview |  Sample

You'll use different methods for calling member functions in a CTreeCtrl object depending on how the object was created:

• If the tree control is in a dialog box, use a member variable of type CTreeCtrl that you create in the dialog box class.
  
  
• If the tree control is a child window, use the CTreeCtrl object (or pointer) you used to construct the object.
  
  
• If you're using a CTreeView object, use the function CTreeView::GetTreeCtrl to get a reference to the tree control. You can initialize another reference with this value or assign the address of the reference to a CTreeCtrl pointer.
