Overview

This Transition creates a fade effect animation that spans its duration. This is done by updating the opacity variable of the node at regular interval.

It starts from the fromValue if provided else uses the node's opacity value.

It stops at the toValue value if provided else it will use start value plus byValue.

The toValue takes precedence if both toValue and byValue are specified.

Code Segment Example:


import javafx.scene.shape.*;
import javafx.animation.transition.*;

...

    var node = Rectangle {
        x: 100 y: 40
        height: 100 width:  100
        arcHeight: 50 arcWidth: 50
        fill: Color.VIOLET
    }

    var fadeTransition = FadeTransition {
        duration: 3s node: node 
        fromValue: 1.0 toValue: 0.3
        repeatCount:4 autoReverse: true
    }
    fadeTransition.play();

Variable Summary

accessnametypeCan ReadCan InitCan WriteDefault Valuedescription
publicbyValueNumberTransition.UNDEFINED

Specifies the incremented stop opacity value, from the start, of this Transition.

publicfromValueNumberTransition.UNDEFINED

Specifies the start opacity value for this Transition.

publictoValueNumberTransition.UNDEFINED

Specifies the stop opacity value for this Transition.

Inherited Variables

javafx.animation.transition.Transition

accessnametypeCan ReadCan InitCan WriteDefault Valuedescription
publicactionfunction():Voidnull

The action to be executed at the end of this duration.

publicautoReverseBooleanfalse

Defines whether this Transition reverses direction on alternating cycles.

Defines whether this Transition reverses direction on alternating cycles. If true, the transition will proceed forward on the first cycle, then reverses on the second cycle, and so on. The default value is false, indicating that the transition will loop such that each cycle proceeds forward from the initial KeyFrame.

false

Profile: common

 
public-readcurrentRateNumber

Defines the current direction/rate at which the transition is being played.

Defines the current direction/rate at which the transition is being played. Rate 1.0 is normal play, and -1.0 is backwards.

Profile: common

 
publicdurationDuration0

The length of this Transition, in milliseconds.

The length of this Transition, in milliseconds. This may only be changed prior to starting the transition or after the transition has ended.

0

Profile: common

 
publicinterpolateInterpolatorEASEBOTH

Controls the timing for acceleration and deceleration at each transition cycle.

Controls the timing for acceleration and deceleration at each transition cycle. This may only be changed prior to starting the transition or after the transition has ended. Default interpolator is set to Interpolator#EASEBOTH.

EASEBOTH

Profile: common

 
publicnodeNodenull

The target node of this Transition.

protectedparentTransitionsubclasssubclasssubclassnull

The parent of this Transition.

The parent of this Transition. If this transition has not been added to another transition, such as ParallelTransition and SequentialTransition, then parent will be null.

null

Profile: common

 
public-readpausedBoolean

Read-only var that indicates whether this Transition is currently paused.

Read-only var that indicates whether this Transition is currently paused.

This value is initially false. It will become true after pause() has been called on a running transition, and then becomes false again after an explicit call to play(), playFromStart() or stop().

Note that running will remain true even when paused==true.

Profile: common

 
publicrateNumber1.0

Defines the direction/rate at which the transition is being played.

Defines the direction/rate at which the transition is being played. Rate 1.0 is normal play, and -1.0 is backwards.

1.0

Profile: common

 
publicrepeatCountNumber1.0

Defines the number of cycles in this transition.

Defines the number of cycles in this transition. The repeatCount may be INDEFINITE for transition that repeat indefinitely, but must otherwise be >= 0. The default value is 1.

1.0

Profile: common

 
public-readrunningBoolean

Read-only var that indicates whether this Transition is currently running.

Read-only var that indicates whether this Transition is currently running.

This value is initially false. It will become true after start() has been called, and then becomes false again after the transition ends naturally, or after an explicit call to stop().

Note that running will remain true even when paused==true.

Profile: common

 
publictimeDuration0

Defines the reference elapsed time offset within the Timeline.

Defines the reference elapsed time offset within the Timeline. If timeline is running, it jumps to this time position immediately. If not running, then it will set the current time position to this value and start from here next time play() is called.

0

protectedtimelineTimelinesubclasssubclasssubclass

An internal Timeline that get created at the creation of this Transition.

An internal Timeline that get created at the creation of this Transition. It is used to control to the transition operations, such as play() and pause().

Profile: common

 
protectedtimelineDirtyBooleansubclasssubclasssubclasstrue

A Boolean value to indicate, to the subclass, its internal timeline need to be rebuilt.

A Boolean value to indicate, to the subclass, its internal timeline need to be rebuilt. It is the subclass responsibility to set this value to false once the timeline is rebuilt.

true

Profile: common

 
protectedUNDEFINEDNumbersubclass

A Number value which do not map to a valid value for use in animation of node.

A Number value which do not map to a valid value for use in animation of node. This value is used to indicate a Number variable is not initialized or manipulated by a user program.
