To check whether a node is a root node or not, use the isRoot() method. This returns a boolean value. TRUE if the node is a root node, else FALSE is returned. For example, TRUE is returned since the following node is a root node −node.isRoot()Another example, FALSE is returned since the following node isn’t a root node −node2.isRoot()The following is an example to check whether a node is a root node or not −Examplepackage my; import javax.swing.JFrame; import javax.swing.JTree; import javax.swing.tree.DefaultMutableTreeNode; public class SwingDemo {    public static void main(String[] args) throws Exception {       JFrame frame ...

The matte border gives a “matte” look. Let’s say the following is our component −JLabel label; label = new JLabel("This has matte border!");Let us create a matte border with BorderFactory class. Here, we have given color YELLOW using the Color class −label.setBorder(BorderFactory.createMatteBorder(3, 5, 10, 5, Color.YELLOW));The following is an example to create a Matte-look border −Examplepackage my; import javax.swing.BorderFactory; import java.awt.Color; import java.awt.Font; import javax.swing.JFrame; import javax.swing.JLabel; public class SwingDemo {    public static void main(String[] args) throws Exception {       JFrame frame = new JFrame("Demo");       JLabel label;       label = new JLabel("This ...

The etched border gives an ‘etched’ look. Let’s say the following is our component −JLabel label; label = new JLabel("This has etched border with an 'etched' look!");Let us create an etched border with BorderFactory class −label.setBorder(BorderFactory.createEtchedBorder());The following is an example to create etched border for a component using BorderFactory class −Examplepackage my; import javax.swing.BorderFactory; import java.awt.Font; import javax.swing.JFrame; import javax.swing.JLabel; public class SwingDemo {    public static void main(String[] args) throws Exception {       JFrame frame = new JFrame("Demo");       JLabel label;       label = new JLabel("This has etched border with an 'etched' look!"); ...

To enable multiple selections in a JFileChooser dialog, use the setMultiSelectionEnabled() to be TRUE −JFileChooser file = new JFileChooser(); file.setMultiSelectionEnabled(true);The following is an example to enable multiple selections in a JFileChooser Dialog −Examplepackage my; import javax.swing.JFileChooser; public class SwingDemo {    public static void main(String[] args) {       JFileChooser file = new JFileChooser();       file.setMultiSelectionEnabled(true);       file.setFileSelectionMode(JFileChooser.FILES_AND_DIRECTORIES);       file.setFileHidingEnabled(false);       if (file.showOpenDialog(null) == JFileChooser.APPROVE_OPTION) {          java.io.File f = file.getSelectedFile();          System.err.println(f.getPath());       }    } }Output

The result FALSE for is FileHidingEnabled() means the hidden files are displayed in the FileChooser. The following will display FALSE since file isn’t hidden −JFileChooser file = new JFileChooser(); file.setMultiSelectionEnabled(false); file.setFileSelectionMode(JFileChooser.FILES_AND_DIRECTORIES); file.setFileHidingEnabled(false); boolean res = file.isFileHidingEnabled();Above, at first, we have displayed the file by setting hidden to be FALSE −file.setFileHidingEnabled(false);The following is an example −Examplepackage my; import javax.swing.JFileChooser; public class SwingDemo {    public static void main(String[] args) {       JFileChooser file = new JFileChooser();       file.setMultiSelectionEnabled(false);       file.setFileSelectionMode(JFileChooser.FILES_AND_DIRECTORIES);       file.setFileHidingEnabled(false);       boolean res = file.isFileHidingEnabled();       System.out.println("File are ...

In this article, you'll learn how to position the title of a border in a Java Swing application using the setTitlePosition() method. We'll position the title above the border's top line by utilizing the TitledBorder.ABOVE_TOP constant. This technique is useful for customizing the appearance of your Swing components. To set title position, use the setTitlePosition() method in Java. Let’s say we have to position the title above the border's top line. For that, use the constant ABOVE_TOP for the border − setTitlePosition(TitledBorder.ABOVE_TOP); Steps to set title position Following are the steps to set title position in Java − ... Read More

To set TitleBorder direction, you need to use the constants and set it for border. For example, for direction center −TitledBorder border = BorderFactory.createTitledBorder("Border"); border.setTitlePosition(TitledBorder.CENTER);Above, we have set the setTitlePosition() for the direction.The following is an example to set TitledBorder direction in Java −Examplepackage my; import java.awt.BorderLayout; import java.awt.Container; import javax.swing.BorderFactory; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.border.TitledBorder; public class SwingDemo {    public static void main(String args[]) {       JFrame frame = new JFrame("Demo");       frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);       TitledBorder border = BorderFactory.createTitledBorder("Border");       border.setTitlePosition(TitledBorder.CENTER);       TitledBorder border2 = new TitledBorder(   ...
