I'm creating a Java GUI using Swing with Eclipse and Window Builder Pro. I'm using JButtons
and JToggleButtons
. I want to change toggle button's state from another button.
For example, when I click the clear grid, all the toggle buttons will be 'not selected'.
How can I do this? What are the methods that I have to use for toggle buttons and buttons?
toggleButton. setTextOn(textOn); // Sets the text for when the button is in the checked state. To set the text using xml, use the following: android:textOff="The text for the button when it is not checked." android:textOn="The text for the button when it is checked."
We can do that by using the HTML label tag and HTML input type = checkbox. HTML code: The HTML code is used to create a structure of toggle switch. Since it does not contain CSS so it is just a simple structure.
The ToggleButton widget acts like a checkbox. When you touch or click it, the state toggles between 'normal' and 'down' (as opposed to a Button that is only 'down' as long as it is pressed). Only one of the buttons can be 'down'/checked at the same time.
toggleButton.setSelected(boolean b)
import java.awt.BorderLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.AbstractButton;
import javax.swing.JFrame;
import javax.swing.JToggleButton;
public class JToggleButtonAction {
public static void main(String args[]) {
JFrame frame = new JFrame("Selecting Toggle");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JToggleButton toggleButton = new JToggleButton("Toggle Button");
final JToggleButton toggleButton1 = new JToggleButton("Another Toggle Button");
ActionListener actionListener = new ActionListener() {
@Override
public void actionPerformed(ActionEvent actionEvent) {
AbstractButton abstractButton = (AbstractButton) actionEvent.getSource();
boolean selected = abstractButton.getModel().isSelected();
System.out.println("Action - selected=" + selected + "\n");
toggleButton1.setSelected(selected);
}
};
toggleButton.addActionListener(actionListener);
frame.add(toggleButton, BorderLayout.NORTH);
frame.add(toggleButton1, BorderLayout.SOUTH);
frame.pack();
frame.setVisible(true);
}
}
Add actionListener to your JButton and in actionPerformed(ActionEvent) method change the state of all JToggleButtons. Make sure all your JToggleButton is accessible in this method. A simple example will be..
JFrame frame = new JFrame("Panel image demo");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setSize(400, 400);
frame.setLayout(new FlowLayout());
final JToggleButton[] button = new JToggleButton[10];
for (int i = 0; i < button.length; i++) {
button[i] = new JToggleButton("Toggle Us");
frame.add(button[i]);
}
JButton jButton = new JButton("Toggle that button");
jButton.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
for (JToggleButton jToggleButton : button) {
jToggleButton.setSelected(!jToggleButton.isSelected()); // <-- this will change the state of toggle button
}
}
});
frame.add(jButton);
frame.setVisible(true);
