TreeView_SetHot macro (commctrl.h)
[Intended for internal use; not recommended for use in applications. This macro may not be supported in future versions of Windows.]
Sets the hot item for a tree-view control. You can use this macro or send the TVM_SETHOT message explicitly.
void TreeView_SetHot( hwnd, hitem );
Handle to the tree-view control.
Handle to the new hot item. If this value is NULL, the tree-view control will be set to have no hot item.
The hot item is the item that the mouse is hovering over. The TVM_SETHOT message sent by this macro makes an item look like it is the hot item even if the mouse is not hovering over it.
If it succeeds, the TVM_SETHOT message causes the hot item to be redrawn.
The TVM_SETHOT message is ignored if hitem is NULL and the tree-view control is tracking the mouse.
