ArrowHandleCap() public static method

Draw an arrow like those used by the move tool.

public static ArrowHandleCap ( int controlID, Vector3 position, Quaternion rotation, float size, EventType eventType ) : void
controlID int The control ID for the handle.
position Vector3 The world-space position of the handle's start point.
rotation UnityEngine.Quaternion The rotation of the handle.
size float The size of the handle in world-space units.
eventType EventType Event type for the handle to act upon. By design it handles EventType.Layout and EventType.Repaint events.
return void
