In this example we are going to see how to use Java JToggleButton Example
Java Code:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 | import java.awt.BorderLayout; import java.awt.Container; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.awt.event.ItemEvent; import java.awt.event.ItemListener; import javax.swing.AbstractButton; import javax.swing.ButtonModel; import javax.swing.JFrame; import javax.swing.JToggleButton; import javax.swing.event.ChangeEvent; import javax.swing.event.ChangeListener; public class Main { public static void main(String args[]) { String title = (args.length == 0 ? "Selecting Toggle" : args[0]); JFrame frame = new JFrame(title); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); JToggleButton toggleButton = new JToggleButton("Selected"); ActionListener actionListener = new ActionListener() { public void actionPerformed(ActionEvent actionEvent) { AbstractButton abstractButton = (AbstractButton) actionEvent.getSource(); boolean selected = abstractButton.getModel().isSelected(); System.out.println("Action - selected=" + selected + "\n"); } }; ChangeListener changeListener = new ChangeListener() { public void stateChanged(ChangeEvent changeEvent) { AbstractButton abstractButton = (AbstractButton) changeEvent.getSource(); ButtonModel buttonModel = abstractButton.getModel(); boolean armed = buttonModel.isArmed(); boolean pressed = buttonModel.isPressed(); boolean selected = buttonModel.isSelected(); System.out.println("Changed: " + armed + "/" + pressed + "/" + selected); } }; ItemListener itemListener = new ItemListener() { public void itemStateChanged(ItemEvent itemEvent) { int state = itemEvent.getStateChange(); if (state == ItemEvent.SELECTED) { System.out.println("Selected"); } else { System.out.println("Deselected"); } } }; // Attach Listeners toggleButton.addActionListener(actionListener); toggleButton.addChangeListener(changeListener); toggleButton.addItemListener(itemListener); Container contentPane = frame.getContentPane(); contentPane.add(toggleButton, BorderLayout.NORTH); JToggleButton toggleButton2 = new JToggleButton("Focused"); contentPane.add(toggleButton2, BorderLayout.CENTER); JToggleButton toggleButton3 = new JToggleButton("Not Selected"); contentPane.add(toggleButton3, BorderLayout.SOUTH); frame.setSize(300, 125); frame.setVisible(true); } } |
Output:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 | Changed: true/false/false Changed: true/true/false Changed: true/true/true Selected Changed: true/false/true Action - selected=true Changed: false/false/true Changed: true/false/true Changed: true/true/true Changed: true/true/false Deselected Changed: true/false/false Action - selected=false Changed: false/false/false |
