get_angle

Description:

[ CCode ( cname = "gdk_events_get_angle" ) ]
public bool get_angle (Event event2, out double angle)

Returns the relative angle from event1 to event2.

The relative angle is the angle between the X axis and the line through both events' positions. The rotation direction for positive angles is from the positive X axis towards the positive Y axis.

This assumes that both events have X/Y information. If not, this function returns false.

Parameters:

event2	second `GdkEvent`
angle	return location for the relative angle between both events
event1	first `GdkEvent`

Returns:

true if the angle could be calculated.
