Once a class of mouse events have been made visible in a window, calling the wgetch function on that window may return KEY_MOUSE as an indicator that a mouse event has been queued. To read the event data and pop the event off the queue, call getmouse. This function will return OK if a mouse event is actually visible in the given window, ERR otherwise. When getmouse returns OK, the data deposited as y and x in the event structure coordinates will be screen-relative character-cell coordinates. The returned state mask will have exactly one bit set to indicate the event type.
The ungetmouse function behaves analogously to ungetch. It pushes a KEY_MOUSE event onto the input queue, and associates 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 otherwise. 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 coordinates from stdscr-relative coordinates to screen-relative coordinates or vice versa. Please remember, that stdscr-relative coordinates are not always identical to screen-relative coordinates due to the mechanism to reserve lines on top or bottom of the screen for other purposes (ripoff() call, see also slk_... functions). 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 screen-relative coordinates and returned through the pointers. If the conversion 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 screen-relative coordinates. They are converted to stdscr-relative coordinates if the window win encloses this point. In this case the function returns TRUE. If one of the parameters is NULL or the point is not inside the window, FALSE is returned. Please notice, that the referenced coordinates are only replaced by the converted coordinates if the transformation was successful.
The mouseinterval function sets the maximum time (in thousands of a second) that can elapse between press and release events for them to be recognized as a click. Use mouseinterval(-1) to disable click resolution. This function returns the previous interval value. The default is one sixth of a second.
Note that mouse events will be ignored when input is in cooked mode, and will cause an error beep when cooked mode is being simulated in a window by a function such as getstr that expects a linefeed for input-loop termination.
