Заметки
Each tree control item is bounded by a graphics rectangle. Whenever a point in that rectangle is clicked, the item is said to be hit. This method returns the largest rectangle such that when a point in the rectangle is clicked, the item identified by the hItem parameter is hit.
This method sends the TVM_GETITEMPARTRECT message, which is described in the Windows SDK. For more information, see the TreeView_GetItemPartRect macro.
