HHT_ONDIVIDER

The point is on the divider between two header items.

HHT_ONDIVOPEN

The point is on the divider of an item that has a width of zero. Dragging the divider reveals the item instead of resizing the item to the left of the divider.

The point is inside the bounding rectangle of the header control.

HHT_TOLEFT

The point is to the left of the bounding rectangle of the header control.
