are not 5 elements long. (EVENT_HEAD): Work correctly on all sorts of events, not just events with parameters. (EVENT_WINDOW, EVENT_BUFFER_POSN, EVENT_SCROLLBAR_BUTTON, EVENT_WINDOW_POSN, EVENT_TIMESTAMP): These aren't useful anymore; this information may appear twice in an event. These are replaced by the POSN_ accessors, which are meant to be composed with the EVENT_START and EVENT_END accessors. (EVENT_START, EVENT_END): Two new accessors, to get at the starting and ending position of an event. (POSN_WINDOW, POSN_BUFFER_POSN, PONS_SCROLLBAR_BUTTON, POSN_WINDOW_POSN, POSN_TIMESTAMP): New macros, to futher diasassemble the values returned by EVENT_START and EVENT_END. * keyboard.h (Qevent_unmodified): Extern declaration replaced by... (Qevent_symbol_elements): This. (EVENT_HEAD_UNMODIFIED): Use the Qevent_symbol_elements property, rather than the Qevent_unmodified property.
