#include <tickit.h>

typedef int TickitWindowEventFn(TickitWindow *win, TickitEventFlags flags,

DESCRIPTION¶

tickit_window_bind_event() adds a new event handler to the list of handlers stored by the window, 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 window 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_window_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_window_bind_event() returns an identifier integer. tickit_window_unbind_event_id() returns no value.
