Button.ch contains manifest constants for the ListBox:hitTest()
return value.
hitTest() is a method of the ListBox class that is used for
determining if the mouse cursor is within the region of the screen
that the list box occupies.
Note: When a scroll bar is present, its hitTest() method is
automatically called to determine if the mouse cursor is within its
region. If ScrollBar:hitTest() succeeds in determining that a "hit"
has been achieved, ListBox:hitTest() returns the appropriate scroll
bar hit test return code.
