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.*;
...
Rectangle rect = new Rectangle (100, 40, 100, 100);
rect.setArcHeight(50);
rect.setArcWidth(50);
rect.setFill(Color.VIOLET);
FadeTransition ft = new FadeTransition(Duration.millis(3000), rect);
ft.setFromValue(1.0);
ft.setToValue(0.3);
ft.setCycleCount(4);
ft.setAutoReverse(true);
ft.play();

node
The target node of thisTransition
.It is not possible to change the target
node
of a runningFadeTransition
. If the value ofnode
is changed for a runningFadeTransition
, the animation has to be stopped and started again to pick up the new value.- See Also:
-
duration
The duration of thisFadeTransition
.It is not possible to change the
duration

. If the value ofduration

duration
is a millisecond, the granularity depends on the underlying operating system and will in general be larger. For example animations on desktop systems usually run with a maximum of 60fps which gives a granularity of ~17 ms. Setting duration to value lower thanDuration.ZERO
will result inIllegalArgumentException

interpolate
protected void interpolate(double frac) The methodinterpolate()
has to be provided by implementations ofTransition
. While aTransition
is running, this method is called in every frame. The parameter defines the current position with the animation. At the start, the fraction will be0.0
and at the end it will be1.0
. How the parameter increases, depends on theinterpolator
, e.g. if theinterpolator
isInterpolator.LINEAR
, the fraction will increase linear. This method must not be called by the user directly.- Specified by:
interpolate
in classTransition
- Parameters:
frac
- The relative position
