To align multiple buttons with different height in Java, try the following example, Here, we have set 5 buttons with GridBagConstraints −GridBagConstraints constraints = new GridBagConstraints(); constraints.insets = new Insets(5, 5, 5, 5); constraints.anchor = GridBagConstraints.WEST;In addition, to set different height for different buttons, we have used −component. getPreferredSize().heightThe following is an example to align multiple buttons with different height −Examplepackage my; import java.awt.Dimension; import java.awt.GridBagConstraints; import java.awt.GridBagLayout; import java.awt.Insets; import javax.swing.JButton; import javax.swing.JFrame; import javax.swing.JPanel; public class SwingDemo {    public static void main(String[] args) {       final JFrame frame = new JFrame(SwingDemo.class.getSimpleName());       frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);       JPanel panel = new JPanel(new GridBagLayout());       GridBagConstraints constraints = new GridBagConstraints();       constraints.insets = new Insets(5,  5,  5,  5);       constraints.anchor = GridBagConstraints.WEST;     ...

To set arrow buttons in a frame, let us first create a frame −JFrame frame = new JFrame();Now, set the layout for the frame wherein all the arrow buttons would be displayed −frame.setLayout(new GridLayout(0, 5));Set the arrow buttons for all the locations −frame.add(new BasicArrowButton(BasicArrowButton.EAST)); frame.add(new BasicArrowButton(BasicArrowButton.NORTH)); frame.add(new BasicArrowButton(BasicArrowButton.SOUTH)); frame.add(new BasicArrowButton(BasicArrowButton.WEST));The following is an example to set all the arrow buttons in a frame −Examplepackage my; import java.awt.GridLayout; import javax.swing.Box; import javax.swing.Icon; import javax.swing.ImageIcon; import javax.swing.JButton; import javax.swing.JFrame; import javax.swing.plaf.basic.BasicArrowButton; public class SwingDemo {    public static void main(String[] args) {       JButton button1 = new JButton("One");     ...

To add icon to a button, use the Icon class, which will allow you to add an image to the button.We are creating a button wherein we are adding an icon with Icon class −Icon icon = new ImageIcon("E:\editicon.PNG"); JButton button7 = new JButton(icon);Above, we have set icon for button 7.The following is an example to add icon to JButton−Examplepackage my; import javax.swing.Box; import javax.swing.Icon; import javax.swing.ImageIcon; import javax.swing.JButton; import javax.swing.JFrame; public class SwingDemo {    public static void main(String[] args) {       JButton button1 = new JButton("One");       JButton button2 = new JButton("Two");     ...

To allow multiple selection of nodes not necessarily contiguous, set the selection mode for tree to be DISCONTIGUOUS_TREE_SELECTION −tree.getSelectionModel().setSelectionMode(TreeSelectionModel.DISCONTIGUOUS_TREE_SELECTION);The following is an example to allow multiple selection of nodes, which are not necessarily contigous −Examplepackage my; import javax.swing.JFrame; import javax.swing.JTree; import javax.swing.tree.DefaultMutableTreeNode; import javax.swing.tree.TreeSelectionModel; public class SwingDemo {    public static void main(String[] args) throws Exception {       JFrame frame = new JFrame("Demo");       DefaultMutableTreeNode node = new DefaultMutableTreeNode("Products");       DefaultMutableTreeNode node1 = new DefaultMutableTreeNode("Clothing");       DefaultMutableTreeNode node2 = new DefaultMutableTreeNode("Electronics");       DefaultMutableTreeNode node3 = new DefaultMutableTreeNode("Home Decor");       DefaultMutableTreeNode node4 = new DefaultMutableTreeNode("Furniture");       node.add(node1);       node.add(node2);       node.add(node3);       node.add(node4);       DefaultMutableTreeNode one = new DefaultMutableTreeNode("Shirt");       DefaultMutableTreeNode two = new DefaultMutableTreeNode("Trousers");       DefaultMutableTreeNode three = new DefaultMutableTreeNode("Jeans");       DefaultMutableTreeNode four = new DefaultMutableTreeNode("Mobiles");   ...

Let us first create a demo table −JTable table = new JTable(tableModel);Now, add a column to it −tableModel.addColumn("Languages");Add some rows to the table using insertRow() method −tableModel.insertRow(0, new Object[] { "CSS" }); tableModel.insertRow(0, new Object[] { "HTML5" }); tableModel.insertRow(0, new Object[] { "JavaScript" }); tableModel.insertRow(0, new Object[] { "jQuery" }); tableModel.insertRow(0, new Object[] { "AngularJS" });The following is an example to add a row to a table with DefaultTableModel −Examplepackage my; import javax.swing.JFrame; import javax.swing.JScrollPane; import javax.swing.JTable; import javax.swing.table.DefaultTableModel; public class SwingDemo {    public static void main(String[] argv) throws Exception {       DefaultTableModel tableModel = new DefaultTableModel(); ...

To disable only the horizontal scrollbar in Java, use the JScrollPane.HORIZONTAL_SCROLLBAR_NEVER. Let’s say you created a Box with some button components. Now, create a JScrollPane −JScrollPane scrollPane = new JScrollPane();Set the Viewport view as Box −scrollPane.setViewportView(box);Now, disable the horizontal scrollbar −scrollPane.setHorizontalScrollBarPolicy(JScrollPane.HORIZONTAL_SCROLLBAR_NEVER);The following is an example to disable only the horizontal scrollbar −Examplepackage my; import java.awt.BorderLayout; import java.awt.Dimension; import javax.swing.Box; import javax.swing.JButton; import javax.swing.JFrame; import javax.swing.JScrollPane; public class SwingDemo {    public static void main(String args[]) {       JFrame frame = new JFrame("Demo");       frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);       JButton button1 = new JButton("Tutorials");       JButton ...

Box is lightweight container that uses a BoxLayout object as its layout manager. To display components from left to right, use Box createHorizontalBox() method.Let us first create some button components −JButton button1 = new JButton("One"); JButton button2 = new JButton("Two"); JButton button3 = new JButton("Three"); JButton button4 = new JButton("Four"); JButton button5 = new JButton("Five"); JButton button6 = new JButton("Six");Now, crate a Box and align all the buttons from left to right −Box box = Box.createHorizontalBox(); box.add(button1); box.add(button2); box.add(button3); box.add(button4); box.add(button5); box.add(button6);The following is an example to create a Box to display components from left to right −Examplepackage my; import ...

Use the getPreviousNode() method to get the previous node of this node in Java. Here, we are displaying the previous node of child node “eight” −System.out.println("Get Previous Node = "+eight.getPreviousNode());The following is an example to get the previous node from a JTree −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 = new JFrame("Demo");       DefaultMutableTreeNode node = new DefaultMutableTreeNode("Products");       DefaultMutableTreeNode node1 = new DefaultMutableTreeNode("Clothing (Product1 - P66778)");       DefaultMutableTreeNode node2 = new DefaultMutableTreeNode("Accessories (Product2 - ...

To disable auto resizing, you need to use the setAutoResizeMode() method. After that, set the table to AUTO_RESIZE_OFF.Let’s say the following is our table −String[][] rec = {    { "1", "Virat", "840" },    { "2", "David", "835" },    { "3", "Shikhar", "656" },    { "4", "Steve", "530" },    { "5", "Kane", "515" },    { "6", "Eion", "509" },    { "7", "AB de Villiers", "498" },    { "8", "Quinton", "470" },    { "9", "Glenn", "410" },    { "10", "Tom", "360" },    { "11", "Johnny", "320" },    { "12", "Shreyas", ...
