JavaFX

EXEMPLO 1: Botão de painel

package paineis;

import javafx.application.Application;

import javafx.scene.Scene;

import javafx.scene.control.Button;

import javafx.scene.layout.StackPane;

import javafx.stage.Stage;

/**

public class BotaoPainel extends Application{

    StackPane painel = new StackPane();

    @Override

    public void start(Stage stage) throws Exception {

        painel.getChildren().add(new Button("Clique aqui"));

        

        Scene scene = new Scene(painel, 200, 50);

        stage.setTitle("Botão dentro de um painel");

        stage.setScene(scene);

        stage.show();

    }

    public static void main(String[] args) {

        Application.launch(args);

    }

}

EXEMPLO 2: Circulo

package paineis;

import javafx.application.Application;

import javafx.scene.Scene;

import javafx.scene.layout.Pane;

import javafx.scene.paint.Color;

import javafx.scene.shape.Circle;

import javafx.stage.Stage;

/**

public class Circulo extends Application{

    @Override

    public void start(Stage stage){

        Circle circle = new Circle();

        circle.setCenterX(100);//cpordenada

        circle.setCenterY(100);//coordenada

        circle.setRadius(50);

        circle.setStroke(Color.BLACK);

        circle.setFill(Color.WHITE);

        

        Pane pane = new Pane();

        pane.getChildren().add(circle);

        

        Scene scene = new Scene(pane, 200, 200);

        stage.setTitle("Exibindo um circulo");

        stage.setScene(scene);

        stage.show();

        

    }

    public static void main(String[] args) {

        Application.launch(args);

    }

}

EXEMPLO 3: Circulo centralizado

package paineis;

import javafx.application.Application;

import javafx.scene.Scene;

import javafx.scene.layout.Pane;

import javafx.scene.paint.Color;

import javafx.scene.shape.Circle;

import javafx.stage.Stage;

/**

public class CirculoCentralizado extends Application{

    @Override

    

    public void start(Stage stage){

        Pane pane = new Pane();

        

        Circle circle = new Circle();

        circle.centerXProperty().bind(pane.widthProperty().divide(2));

        circle.centerYProperty().bind(pane.heightProperty().divide(2));

        circle.setRadius(50);

        circle.setStroke(Color.BLACK);

        circle.setFill(Color.WHITE);

        //circle.setFill(Color.RED);

        pane.getChildren().add(circle);

        

        Scene scene = new Scene(pane, 200, 200);

        stage.setTitle("Circulo Sempre Centralizado");

        stage.setScene(scene);

        stage.show();

    }

    public static void main(String[] args) {

        Application.launch(args);

    }

}

EXEMPLO 4: Interface com JavaFX

package paineis;

import javafx.application.Application;

import javafx.event.ActionEvent;

import javafx.event.EventHandler;

import javafx.scene.Scene;

import javafx.scene.control.Button;

import javafx.scene.layout.StackPane;

import javafx.stage.Stage;

/**

 *

 * @author HENRIQUE

 */

public class MinhaPrimeiraInterface extends Application {

    @Override

    public void start (Stage primaryStage){

        Button btn = new Button("Sou um Botão");

        Scene scene = new Scene(btn, 200, 250);

        primaryStage.setTitle("Minha Primeira Interface JavaFX");

        primaryStage.setScene(scene);

        primaryStage.show();

        

        Stage stage = new Stage();

        stage.setTitle("Nova janela");

        stage.setScene(new Scene(new Button("Mais um botão"),100, 100));

        stage.show();

    }

    

    public static void main(String[] args) {

        Application.launch(args);

    }

}

EXEMPLO 5: Interface dentro de uma interface

package paineis;

import javafx.application.Application;

import javafx.scene.Scene;

import javafx.scene.control.Button;

import javafx.scene.layout.BorderPane;

import javafx.scene.layout.FlowPane;

import javafx.stage.Stage;

/**

 * @author HENRIQUE

 */

public class PainelDentroDePainel extends Application{

    @Override

    public void start(Stage stage) {

        BorderPane painelPrincipal = new BorderPane();

        FlowPane painelSul = new FlowPane();

        

        painelSul.getChildren().add(new Button("Botão 1"));

        painelSul.getChildren().add(new Button("Botão 2"));

        painelPrincipal.setBottom(painelSul);

        

        Scene scene = new Scene(painelPrincipal, 400, 400);

        stage.setTitle("Painel dentro de um Painel");

        stage.setScene(scene);

        stage.show();

    }

    public static void main(String[] args) {

        Application.launch(args);

    }
