Obtains the motion history for a device; given a starting and ending timestamp, return all events in the motion history for the device in the given range of time.
Some windowing systems do not support motion history, in which case, false
will be returned. (This is not distinguishable from the case where motion history is supported and no events were found.)
- Parameters:
-
window | The window with respect to which which the event coordinates will be reported. |
start | Starting timestamp for range of events to return. |
stop | Ending timestamp for the range of events to return. |
events | Location to store a newly-allocated array of Gdk::TimeCoord, or 0 . |
n_events | Location to store the length of events, or 0 . |
- Returns:
true
if the windowing system supports motion history and at least one event was found.
