returns the widget or gadget that contains the pointer when BSelect
is released or a key is released.

the modal interaction. That is, the widget within which the
interaction must occur, usually a top level shell.
cursor Specifies the cursor to be used for the pointer during the
interaction. This is a standard X cursor name.
confine_to
Specifies whether or not the cursor should be confined to
widget.
event_return
Returns the ButtonRelease or KeyRelease event that causes the
function to return.
RETURN VALUE
Returns the widget or gadget that contains the pointer when BSelect
is released or a key is released. If no widget or gadget contains
the pointer, the function returns NULL.
