NetBeans IDE 7.2 provides a significantly improved performance and coding experience, with new static code analysis capabilities in the Java Editor and smarter project scanning. Other notable features include integration with JavaFX Scene Builder; support for multiple PHP frameworks; updated Groovy support; and enhancements for Java EE, Maven, C/C++ and the NetBeans Platform.

JavaFX TreeView with icon

Example of JavaFX TreeView with icon:

package javafxtest;

import javafx.application.Application;
import javafx.scene.Node;
import javafx.scene.Scene;
import javafx.scene.control.TreeItem;
import javafx.scene.control.TreeView;
import javafx.scene.image.Image;
import javafx.scene.image.ImageView;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;

/**

 */
public class JavaFXtestUI extends Application {
    
    Image nodeImage = new Image(
            getClass().getResourceAsStream("duke_16x16.png"));

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        launch(args);
    }
    
    @Override
    public void start(Stage primaryStage) {
        
        TreeItem<String> treeItemRoot = new TreeItem<> ("Root");
        
        TreeItem<String> nodeItemA = new TreeItem<>("Item A");
        TreeItem<String> nodeItemB = new TreeItem<>("Item B");
        TreeItem<String> nodeItemC = new TreeItem<>("Item C");
        treeItemRoot.getChildren().addAll(nodeItemA, nodeItemB, nodeItemC);
        
        TreeItem<String> nodeItemA1 = new TreeItem<>("Item A1", 
                new ImageView(nodeImage));
        TreeItem<String> nodeItemA2 = new TreeItem<>("Item A2", 
                new ImageView(nodeImage));
        TreeItem<String> nodeItemA3 = new TreeItem<>("Item A3", 
                new ImageView(nodeImage));
        
        nodeItemA.getChildren().addAll(nodeItemA1, nodeItemA2, nodeItemA3);
        
        TreeView<String> treeView = new TreeView<>(treeItemRoot);
        StackPane root = new StackPane();
        root.getChildren().add(treeView);
        
        Scene scene = new Scene(root, 300, 250);
        
        primaryStage.setTitle("java-buddy.blogspot.com");
        primaryStage.setScene(scene);
        primaryStage.show();
    }
}

Simple JavaFX TreeView example

JavaFX provide TreeView control, a view on to a tree root (of type TreeItem). By using a TreeView, it is possible to drill down into the children of a TreeItem, recursively until a TreeItem has no children (that is, it is a leaf node in the tree).

package javafxtest;

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.TreeItem;
import javafx.scene.control.TreeView;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;

/**
 *
 * @web http://java-buddy.blogspot.com/
 */
public class JavaFXtestUI extends Application {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        launch(args);
    }
    
    @Override
    public void start(Stage primaryStage) {
        
        TreeItem<String> treeItemRoot = new TreeItem<> ("Root");
        
        TreeItem<String> nodeItemA = new TreeItem<>("Item A");
        TreeItem<String> nodeItemB = new TreeItem<>("Item B");
        TreeItem<String> nodeItemC = new TreeItem<>("Item C");
        treeItemRoot.getChildren().addAll(nodeItemA, nodeItemB, nodeItemC);
        
        TreeItem<String> nodeItemA1 = new TreeItem<>("Item A1");
        TreeItem<String> nodeItemA2 = new TreeItem<>("Item A2");
        TreeItem<String> nodeItemA3 = new TreeItem<>("Item A3");
        nodeItemA.getChildren().addAll(nodeItemA1, nodeItemA2, nodeItemA3);
        
        TreeView<String> treeView = new TreeView<>(treeItemRoot);
        StackPane root = new StackPane();
        root.getChildren().add(treeView);
        
        Scene scene = new Scene(root, 300, 250);
        
        primaryStage.setTitle("java-buddy.blogspot.com");
        primaryStage.setScene(scene);
        primaryStage.show();
    }
}
