Example
The following code example defines a variable, m_treeCtrl, that is used to access the current tree-view control. The code example also defines an unsigned integer and several HTREEITEM variables. One or more of these variables are used in the next example.
public:
// Variable to access tree control.
CTreeCtrl m_treeCtrl;
// Variable to access splitbutton control.
CSplitButton m_splitbutton;
// Accessibility identifier
UINT accIdUS;
// HTREEITEMs
HTREEITEM hCountry;
HTREEITEM hPA;
HTREEITEM hWA;
The following code example retrieves a handle to the last unexpanded tree-view node item, and then draws a 3D rectangle around that item. In an earlier section of the code example, which is not shown, we created a tree-view that consists of a root country/region node for the United States, subnodes for the states of Pennsylvania and Washington, and tree items for cities in those states.
CRect rect;
HTREEITEM hLast = m_treeCtrl.GetLastVisibleItem();
m_treeCtrl.GetItemPartRect( hLast, TVGIPR_BUTTON, &rect );
m_treeCtrl.GetDC()->Draw3dRect( &rect, RGB(255, 0, 0), RGB(0, 0, 255));
