NAME

       tickit_pen_bind_event, tickit_pen_unbind_event_id - add or remove event handlers

SYNOPSIS

       #include <tickit.h>

       typedef int TickitPenEventFn(TickitPen *tt, TickitEventFlags flags,
           void *info, void *user);

       int tickit_pen_bind_event(TickitPen *tt, TickitPenEvent ev,
           TickitBindFlags flags,
           TickitPenEventFn *fn, void *user);
       void tickit_pen_unbind_event_id(TickitPen *tt, int id);

DESCRIPTION

       tickit_pen_bind_event()  adds  a new event handler to the list of handlers stored by the pen, and returns
       an integer to identify this handler. This handler will be invoked for occurrences of the event  given  by
       the  ev  argument.  When  invoked, func will be passed the pen instance, a flags bitmask, a pointer to an
       event information structure whose type depends on the event, and the user data pointer it  was  installed
       with.

       tickit_pen_unbind_event_id()  removes  an event handler previously added, by the identifier returned when
       it was added, invoking it with the TICKIT_EV_UNBIND flag if it was installed with TICKIT_BIND_UNBIND.

RETURN VALUE

       tickit_pen_bind_event() returns an identifier integer. tickit_pen_unbind_event_id() returns no value.
