JToggleButton Example in Java for Beginners

This exhaustive example illustrates JToggleButton in Swing. This example covers all core methods of the javax.swing.JToggleButton class. The program looks lengthy but it's easy if you go through.

import javax.swing.*;

import java.awt.*;

import javax.swing.text.*;

class JToggleButtonExample extends JFrame

{

JToggleButton t1,t2,t3,t4,t5,t6,t7,t8;

ImageIcon i1,i2,i3,i4,i5,i6,i7;



    public JToggleButtonExample()

        createAndShowGUI();

        setTitle("JToggleButton Demo");

        setLayout(new FlowLayout());

        // Create some image icons

        i1=new ImageIcon("camera.png");

        // Created using

        // default constructor

        // Comes with no text, icon

        // and is not selected

        t1=new JToggleButton();

        // Second constructor

        // object

        t3=new JToggleButton(i1);

        

        // Fourth constructor

        // takes icon and boolean

        // representing whether the

        // toggle button should be

        // selected

        // This icon acts as every icon

        // i.e. it is the same on rollover,

        // selected and rollover selected

        t4=new JToggleButton(i2,true);

        

        // Fifth constructor

        // takes String text on toggle button

        t5=new JToggleButton("Toggle Button 5");

        

        // Sixth constructor

        // takes String text with boolean selected

        // JFrame is opened, because

        // t8 is selected by this time

        t8.setDisabledSelectedIcon(i6);

        

        // Now set disabled icon

        // The icon cannot be seen

        // because once after the

        // toggle button is disabled

        // selection cannot be changed

        // i.e. all the events are blocked

        // they are not generated

        t8.setDisabledIcon(i6);

        

        // Set icon text gap

        // The default gap between

        // icon and text is 4

        // TOP/BOTTOM/CENTER

        // This is with respect to the icon

        // SwingConstants.TOP=1;

        // SwingConstants.BOTTOM=3;

        // SwingConstants.CENTER=0;

        // Default value is 0 (CENTER)

        t7.setVerticalTextPosition(3);

        

        // Set horizontal text position

        // RIGHT/LEFT/CENTER/LEADING/TRAILING

        // TRALIING is the default

        t7.setHorizontalTextPosition(SwingConstants.CENTER);

        

        // When focus, border painted,

        // content area filled is set to false

        // then t7 looks pretty much like a desktop icon!

        t7.setFocusPainted(false);

        t7.setBorderPainted(false);

        t7.setContentAreaFilled(false);

        

        // Print whether t4 is selected
