Class FocusTrigger

java.lang.Object
org.jdesktop.animation.timing.triggers.Trigger
org.jdesktop.animation.timing.triggers.FocusTrigger
All Implemented Interfaces:
FocusListener, EventListener
public class FocusTrigger extends Trigger implements FocusListener
FocusTrigger handles focus events and triggers an animation based on those events. For example, to have anim start when component receives an IN event, one might write the following: 
     FocusTrigger trigger = 
         FocusTrigger.addTrigger(component, anim, FocusTriggerEvent.IN);

  • Constructor Details

    • FocusTrigger

      public FocusTrigger(Animator animator, FocusTriggerEvent event)
      Creates a non-auto-reversing FocusTrigger, which should be added to a Component that will generate the focus events of interest.
      Parameters:
      animator - the Animator that will start when the event occurs
      event - the FocusTriggerEvent that will cause the action to fire

    • FocusTrigger

      public FocusTrigger(Animator animator, FocusTriggerEvent event, boolean autoReverse)
      Creates a FocusTrigger, which should be added to a Component that will generate the focus events of interest.
      Parameters:
      animator - the Animator that will start when the event occurs
      event - the FocusTriggerEvent that will cause the action to fire
      autoReverse - flag to determine whether the animator should stop and reverse based on opposite triggerEvents.

    • addTrigger

      public static FocusTrigger addTrigger(JComponent component, Animator animator, FocusTriggerEvent event)
      Creates a non-auto-reversing FocusTrigger and adds it as a FocusListener to the component.
      Parameters:
      component - component that will generate FocusEvents for this trigger
      animator - the Animator that will start when the event occurs
      event - the FocusTriggerEvent that will cause the action to fire
      Returns:
      FocusTrigger the resulting trigger

    • addTrigger

      public static FocusTrigger addTrigger(JComponent component, Animator animator, FocusTriggerEvent event, boolean autoReverse)
      Creates a FocusTrigger and adds it as a FocusListener to the component.
      Parameters:
      component - component that will generate FocusEvents for this trigger
      animator - the Animator that will start when the event occurs
      event - the FocusTriggerEvent that will cause the action to fire
      autoReverse - flag to determine whether the animator should stop and reverse based on opposite triggerEvents.
      Returns:
      FocusTrigger the resulting trigger

    • focusGained

      public void focusGained(FocusEvent e)
      Called by the object which added this trigger as a FocusListener. This method starts the animator if the trigger is waiting for a IN event.
      Specified by:
      focusGained in interface FocusListener

    • focusLost

      public void focusLost(FocusEvent e)
      Called by the object which added this trigger as a FocusListener. This method starts the animator if the trigger is waiting for a OUT event.
      Specified by:
      focusLost in interface FocusListener
