Class jclass.chart.EventTrigger 

java.lang.Object
   |
   +----jclass.chart.EventTrigger
public class EventTrigger
extends Object
implements JCSerializable
EventTrigger is responsible for defining a mapping from a user event to a Chart action. For example, EventTrigger can be used to map from a Shift+Left-mouse-button set of events to the rotate action. Note that by default all event triggers are mouse down-drag-up events (which occurs as a single sequence of mouse events). All that can vary are the modifiers.

Properties

Name Method
Modifiers The Modifiers property specifies the modifier keys that are pressed during mouse down-drag-up that trigger the action. It is a bit field made up of a mixture of Event.ALT_MASK, Event.CTRL_MASK, Event.META_MASK and Event_SHIFT_MASK. Using the middle mouse button for a trigger is accomplished by specifying a modifier of Event.ALT_MASK. Using the right mouse button for a trigger is accomplished by specifying a modifier of Event.META_MASK.
Action The Action property determines what action will be performed when the specified AWT event occurs. One of EventTrigger.ROTATE, EventTrigger.EDIT, EventTrigger.ZOOM, EventTrigger.TRANSLATE, EventTrigger.PICK or EventTrigger.DEPTH.

Constructors

o EventTrigger 
  public EventTrigger(int mod,
                      int act)
A public constructor that creates a mapping from a series of modifiers to a Chart action.

Parameters:
mod - bitfield of modifiers from Event. Can include Event.SHIFT_MASK, Event.CTRL_MASK, Event.META_MASK and Event.ALT_MASK.
act - action enum, one of ROTATE, ZOOM, TRANSLATE, EDIT, PICK, or DEPTH.

Methods

o getModifiers 
  public int getModifiers()
Gets the value of the Modifiers property for this EventTrigger instance. The modifiers property specifies the modifier keys that are pressed during mouse down-drag-up that trigger the action.

Returns:
bit fields set using Event.ALT_MASK, Event.CTRL_MASK, Event.META_MASK and Event.SHIFT_MASK
o setModifiers 
  public synchronized void setModifiers(int mod)
Sets the value of the modifiers property for this EventTrigger instance. The modifiers property specifies the modifier keys that are pressed during mouse down-drag-up that trigger the action. A modifier of Event.ALT_MASK can be used to specify the use of the middle mouse button for the trigger. A modifier of Event.META_MASK can be used to specify the use of the right mouse button for the trigger.

Parameters:
mod - bit fields set using Event.ALT_MASK, Event.CTRL_MASK, Event.META_MASK and Event.SHIFT_MASK
Throws: IllegalArgumentException
If the modifier is not either 0, Event.SHIFT_MASK, Event.ALT_MASK, Event.META_MASK or Event.CTRL_MASK
o getAction 
  public int getAction()
Gets the value of the Action property for this EventTrigger instance. The Action property determines what action will be performed when the specified AWT event occurs. One of ROTATE, ZOOM TRANSLATE, EDIT, PICK or DEPTH.

Returns:
Enum specifying chart action
o setAction 
  public synchronized void setAction(int act)
Sets the value of the action property for this EventTrigger instance. The action property determines what action will be performed when the specified AWT event occurs. One of ROTATE, EDIT, ZOOM TRANSLATE, PICK or DEPTH.

Parameters:
act - Enum specifying chart action
Throws: IllegalArgumentException
If the action is not one of ROTATE, ZOOM, TRANSLATE, EDIT, PICK or DEPTH.
