Layout em Java

EXEMPLO 1:

package visao;

import javafx.application.Application;

import javafx.geometry.Insets;

import javafx.scene.Scene;

import javafx.scene.layout.StackPane;

import javafx.scene.paint.Color;

import javafx.scene.shape.Rectangle;

import javafx.stage.Stage;

public class LayoutStackPane extends Application{

    @Override

    public void start(Stage primary){

        StackPane stackPane = new StackPane();

        stackPane.setPadding(new Insets(20));

        Rectangle r1 = new Rectangle(300, 300);

        r1.setFill(Color.RED);

        Rectangle r2 = new Rectangle(200, 200);

        r2.setFill(Color.BLUE);

        Rectangle r3 = new Rectangle(100, 100);

        r3.setFill(Color.AQUA);

        Rectangle r4 = new Rectangle(50, 50);

        r4.setFill(Color.BROWN);

        stackPane.getChildren().addAll(r1, r2, r3, r4);

        

        Scene cena = new Scene(stackPane);

        primary.setScene(cena);

        primary.setTitle("Gerenciador de Layout StackPane");

        primary.show();

    }

    public static void main(String[] args) {

        LayoutStackPane.launch(args);

    }

    

}

EXEMPLO 2:

package visao;

import javafx.application.Application;

import javafx.geometry.Insets;

import javafx.scene.Scene;

import javafx.scene.layout.VBox;

import javafx.scene.shape.Rectangle;

import javafx.stage.Stage;

public class LayoutVBox extends Application{

    @Override

    public void start(Stage primaryStage) throws Exception{

        

        VBox vbox = new VBox(10);

        vbox.setPadding(new Insets(20));

        Rectangle r1 = new Rectangle(50, 50);

        Rectangle r2 = new Rectangle(100, 100);

        Rectangle r3 = new Rectangle(25, 100);

        Rectangle r4 = new Rectangle(250, 50);

        VBox.setMargin(r1, new Insets(10, 10, 10, 10));

        vbox.getChildren().addAll(r1, r2, r3, r4);

        Scene cena = new Scene(vbox);

        primaryStage.setScene(cena);

        primaryStage.setTitle("Gerenciador de Layout VBox");

        primaryStage.show();

    }

    

    public static void main(String[] args) {

        LayoutVBox.launch(args);

    }   

}

EXEMPLO 3:

package visao;

import javafx.geometry.Insets;

import javafx.application.Application;

import javafx.scene.Scene;

import javafx.scene.layout.HBox;

import javafx.scene.shape.Rectangle;

import javafx.stage.Stage;

public class LayoutHBox extends Application{

    @Override

    public void start(Stage Henrique){

        HBox hbox = new HBox(15);

        hbox.setPadding(new Insets(20));

        Rectangle r1 = new Rectangle(100, 100);

        Rectangle r2 = new Rectangle(200, 200);

        Rectangle r3 = new Rectangle(50, 200);

        Rectangle r4 = new Rectangle(200, 50);

        HBox.setMargin(r1, new Insets(10, 10, 10, 10));

        hbox.getChildren().addAll(r1, r2, r3, r4);

        

        Scene cena = new Scene(hbox);

        Henrique.setScene(cena);

        Henrique.setTitle("Gerenciador de Layout HBox");

        Henrique.show();

    }

    

    public static void main(String[] args) {

        LayoutHBox.launch(args);

    }

}

EXEMPLO 4:

package visao;

import javafx.application.Application;

import javafx.geometry.Insets;

import javafx.geometry.Orientation;

import javafx.geometry.Pos;

import javafx.scene.Scene;

import javafx.scene.layout.FlowPane;

import javafx.scene.paint.Color;

import javafx.scene.shape.Rectangle;

import javafx.stage.Stage;

public class LayoutFlowPane extends Application{

    @Override

    public void start(Stage primaryKey){

        FlowPane flowPane = new FlowPane(Orientation.VERTICAL);//fluxo de distribuição

        flowPane.setAlignment(Pos.TOP_LEFT);

        flowPane.setPadding(new Insets(20));

        Rectangle r1 = new Rectangle(50, 50);//quadrado 1

        r1.setFill(Color.RED);

        Rectangle r2 = new Rectangle(150, 60);//retangulo vertical

        r2.setFill(Color.BLUE);

        Rectangle r3 = new Rectangle(250, 50);

        r3.setFill(Color.AQUA);

        Rectangle r4 = new Rectangle(250, 50);

        FlowPane.setMargin(r1, new Insets(10, 10, 10, 10));

        flowPane.getChildren().addAll(r1, r2, r3, r4);

        

        Scene cena = new Scene(flowPane);

        primaryKey.setScene(cena);

        primaryKey.setTitle("Gerenciador de Layout FlowPane");

        primaryKey.show();

    }

    public static void main(String[] args) {

        LayoutFlowPane.launch(args);

    }

}
