JavaFX - Transizioni geometriche
Transizione in dissolvenza
Di seguito è riportato il programma che mostra Fade Transition in JavaFX. Salva questo codice in un file con il nomeFadeTransitionExample.java.
import javafx.animation.FadeTransition;
import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.paint.Color;
import javafx.scene.shape.Circle;
import javafx.stage.Stage;
import javafx.util.Duration;
public class FadeTransitionExample extends Application {
@Override
public void start(Stage stage) {
//Drawing a Circle
Circle circle = new Circle();
//Setting the position of the circle
circle.setCenterX(300.0f);
circle.setCenterY(135.0f);
//Setting the radius of the circle
circle.setRadius(100.0f);
//Setting the color of the circle
circle.setFill(Color.BROWN);
//Setting the stroke width of the circle
circle.setStrokeWidth(20);
//Creating the fade Transition
FadeTransition fadeTransition = new FadeTransition(Duration.millis(1000));
//Setting the node for Transition
fadeTransition.setNode(circle);
//Setting the property fromValue of the transition (opacity)
fadeTransition.setFromValue(1.0);
//Setting the property toValue of the transition (opacity)
fadeTransition.setToValue(0.3);
//Setting the cycle count for the transition
fadeTransition.setCycleCount(50);
//Setting auto reverse value to false
fadeTransition.setAutoReverse(false);
//Playing the animation
fadeTransition.play();
//Creating a Group object
Group root = new Group(circle);
//Creating a scene object
Scene scene = new Scene(root, 600, 300);
//Setting title to the Stage
stage.setTitle("Fade transition example");
//Adding scene to the stage
stage.setScene(scene);
//Displaying the contents of the stage
stage.show();
}
public static void main(String args[]){
launch(args);
}
}
Compilare ed eseguire il file java salvato dal prompt dei comandi utilizzando i seguenti comandi.
javac FadeTransitionExample.java
java FadeTransitionExample
All'esecuzione, il programma di cui sopra genera una finestra JavaFX come mostrato di seguito.
