guint get_group0_keyval (GdkEventKey *event)
gint gobble_key_events (guint keyval, gint mask)
 Gobbles next key events on the queue with the same keyval and mask. Returns the number of events consumed.
gint gobble_motion_events (gint mask)
 Gobbles next motion notify events on the queue with the same mask. Returns the number of events consumed.

void sp_event_context_snap_delay_handler (SPEventContext *ec, gpointer const dse_item, gpointer const dse_item2, GdkEventMotion *event, DelayedSnapEvent::DelayedSnapEventOrigin origin)
 Analyses the current event, calculates the mouse speed, turns snapping off (temporarily) if the mouse speed is above a threshold, and stores the current event such that it can be re-triggered when needed (re-triggering is controlled by a watchdog timer)
gboolean sp_event_context_snap_watchdog_callback (gpointer data)
 When the snap delay watchdog timer barks, this method will be called and will re-inject the last motion event in an appropriate place, with snapping being turned on again.

Detailed Description

SPEventContext: base class for event processors

This is per desktop object, which (its derivatives) implements different actions bound to mouse events.
