The ungetmouse function behaves analogously to ungetch.
It pushes a KEY_MOUSE event onto the input queue, and as-
sociates with that event the given state data and screen-
relative character-cell coordinates.

+
+
The wenclose function tests whether a given pair of
screen-relative character-cell coordinates is enclosed by
a given window, returning TRUE if it is and FALSE other-
wise. It is useful for determining what subset of the
screen windows enclose the location of a mouse event.

The wmouse_trafo function transforms a given pair of coor-
dinates from stdscr-relative coordinates to coordinates
- relative to the given window or vice versa. Please remem-

- tical to window-relative coordinates due to the mechanism
- to reserve lines on top or bottom of the screen for other
- purposes (see the ripoffline() and slk_init calls, for ex-
- ample). If the parameter to_screen is TRUE, the pointers
- pY, pX must reference the coordinates of a location inside
- the window win. They are converted to window-relative co-
- ordinates and returned through the pointers. If the con-
- version was successful, the function returns TRUE. If one
- of the parameters was NULL or the location is not inside
- the window, FALSE is returned. If to_screen is FALSE, the
- pointers pY, pX must reference window-relative coordi-
- nates. They are converted to stdscr-relative coordinates
- if the window win encloses this point. In this case the
