How to set the maximized bounds for a Frame in Java?
To set maximized bounds, use the setMaximizedBounds() method. Here, we will create a frame, which when maximized will form a shape −
JFrame frame = new JFrame("Login!");Above, we have created a frame and now we will use the Rectangle class to specify an area of coordinates −
Rectangle bounds = new Rectangle(50, 10, 100, 200); Now, set maximized bounds − frame.setMaximizedBounds(bounds);
The following is an example to set the maximized bounds for a frame −
Example
package my;
import java.awt.GridLayout;
import java.awt.Rectangle;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPasswordField;
import javax.swing.JTextField;
import javax.swing.SwingConstants;
public class SwingDemo {
public static void main(String[] args) throws Exception {
JFrame frame = new JFrame("Login!");
JLabel label1, label2, label3;
frame.setLayout(new GridLayout(2, 2));
label1 = new JLabel("DeptId", SwingConstants.CENTER);
label2 = new JLabel("SSN", SwingConstants.CENTER);
label3 = new JLabel("Password", SwingConstants.CENTER);
JTextField deptid = new JTextField(20);
JTextField ssn = new JTextField(20);
JPasswordField passwd = new JPasswordField();
passwd.setEchoChar('*');
frame.add(label1);
frame.add(label2);
frame.add(label3);
frame.add(deptid);
frame.add(ssn);
frame.add(passwd);
Rectangle bounds = new Rectangle(50, 10, 100, 200);
frame.setMaximizedBounds(bounds);
frame.setSize(550, 200);
frame.setVisible(true);
}
}Output
Now, maximize it and you can see the rectangle bounds set above −
