- * generateMouseEvent:
+ * SPI_generateMouseEvent:
* @x: a #long indicating the screen x coordinate of the mouse event.
* @y: a #long indicating the screen y coordinate of the mouse event.
* @name: a string indicating which mouse event to be synthesized
- * (e.g. "button1", "button2", "mousemove").
+ * (e.g. "b1p", "b1c", "b2r", "rel", "abs").
*
* Synthesize a mouse event at a specific screen coordinate.
- * Not Yet Implemented.
+ * Most AT clients should use the #AccessibleAction interface when
+ * tempted to generate mouse events, rather than this method.
+ * Event names: b1p = button 1 press; b2r = button 2 release;
+ * b3c = button 3 click; b2d = button 2 double-click;
+ * abs = absolute motion; rel = relative motion.
*
+ * Returns: #TRUE if successful, otherwise #FALSE.
