public final class FadeTransition extends Transition
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.*;
...
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();

protected void interpolate(double frac)
interpolate()
has to be provided by implementations of
Transition
. While a Transition
is running, this method is
called in every frame.
The parameter defines the current position with the animation. At the
start, the fraction will be 0.0
and at the end it will be
1.0
. How the parameter increases, depends on the
interpolator
, e.g. if the
interpolator
is Interpolator.LINEAR
, the fraction will
increase linear.
This method must not be called by the user directly.interpolate
