TreeView_Select macro (commctrl.h)

  • Article

Selects the specified tree-view item, scrolls the item into view, or redraws the item in the style used to indicate the target of a drag-and-drop operation. You can use this macro or the TreeView_SelectItem, TreeView_SelectSetFirstVisible, or TreeView_SelectDropTarget macros, or you can send the TVM_SELECTITEM message explicitly.

Syntax

void TreeView_Select(
   hwnd,
   hitem,
   code
);

Parameters

hwnd

Type: HWND

Handle to the tree-view control.

hitem

Type: HTREEITEM

Handle to an item. If the hitem parameter is NULL, the control is set to have no selected item.

code

Type: UINT

Action flag. This parameter can be one of the following values:

Value Meaning
TVGN_CARET
 Sets the selection to the given item. The control's parent window receives the TVN_SELCHANGING and TVN_SELCHANGED notification codes.
TVGN_DROPHILITE
 Redraws the given item in the style used to indicate the target of a drag-and-drop operation.
TVGN_FIRSTVISIBLE
 Ensures that the specified item is visible, and, if possible, displays it at the top of the control's window. Tree-view controls display as many items as will fit in the window. If the specified item is near the bottom of the control's hierarchy of items, it might not become the first visible item, depending on how many items fit in the window.

Return value

None

Remarks

If the specified item is the child of a collapsed parent item, the parent's list of child items is expanded to reveal the specified item. In this case, the parent window receives the TVN_ITEMEXPANDING and TVN_ITEMEXPANDED notification codes.
