released. The function then returns the widget or gadget
that contains the pointer when BSelect is released or a key
is released.
widget Specifies the widget ID of a widget to use as the
basis of 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.
