Chapter 21: Tree and List Controls Visual C++ and MFC Fundamentals

After creating the view, you should initiale it. This is usually done in the

OnInitialUpdate() event of the view class. In order to take advantage of the features of

the list control, you should obtain a reference to the CTreeCtrl class that controls the tree

view. Once you have accessed that reference, you can do anything you would do with a

CTreeCtrl variable or pointer. Here is an example of creating a feww items of a tree

view:

void CExerciseView::OnInitialUpdate()

{

CTreeView::OnInitialUpdate();

CTreeCtrl& trCtrl = GetTreeCtrl();

HTREEITEM hItem;

hItem = trCtrl.InsertItem( "Cameroon", 0, 2 );

trCtrl.InsertItem( "Yaounde", 1, 3, hItem );

trCtrl.InsertItem( "Douala", 1, 3, hItem );

trCtrl.InsertItem( "Ebolowa", 1, 3, hItem );

hItem = trCtrl.InsertItem( "U.S.A.", 0, 2 );

trCtrl.InsertItem( "Washington, DC", 1, 3, hItem );

trCtrl.InsertItem( "New York", 1, 3, hItem );

hItem = trCtrl.InsertItem( "Germany", 0, 2 );

trCtrl.InsertItem( "Bonn", 1, 3, hItem );

trCtrl.InsertItem( "Francfort", 1, 3, hItem );

}
