I am trying to do have two button in JFrame
, and I call the setBounds
method of them for setting the positions and size of them and also I passed null
to setLayout1 because I want to use
setBounds` method of component.
Now I want to do something with my code that whenever I resize the frame buttons decoration will change in a suitable form like below pictures:
I know it is possible to use create an object from JPanel
class and add buttons to it and at the end add created panel object to frame, but I am not allowed to it right now because of some reason (specified by professor).
Is there any way or do you have any suggestion?
My code is like this:
public class Responsive
{
public static void main(String[] args)
{
JFrame jFrame = new JFrame("Responsive JFrame");
jFrame.setLayout(null);
jFrame.setBounds(0,0,400,300);
JButton jButton1 = new JButton("button 1");
JButton jButton2 = new JButton("button 2");
jButton1.setBounds(50,50,100,100);
jButton2.setBounds(150,50,100,100);
jFrame.add(jButton1);
jFrame.add(jButton2);
jFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
jFrame.setVisible(true);
}
}
A FlowLayout
with no horizontal spacing, some vertical spacing and large borders could achieve that easily. A null
layout manager is never the answer to a 'responsive' robust GUI.
import java.awt.*;
import javax.swing.*;
import javax.swing.border.EmptyBorder;
public class ResponsiveGUI {
private JComponent ui = null;
ResponsiveGUI() {
initUI();
}
public void initUI() {
if (ui!=null) return;
ui = new JPanel(new FlowLayout(FlowLayout.CENTER, 0, 8));
ui.setBorder(new EmptyBorder(10,40,10,40));
for (int i=1; i<3; i++) {
ui.add(getBigButton(i));
}
}
public JComponent getUI() {
return ui;
}
private final JButton getBigButton(int number) {
JButton b = new JButton("Button " + number);
int pad = 20;
b.setMargin(new Insets(pad, pad, pad, pad));
return b;
}
public static void main(String[] args) {
Runnable r = new Runnable() {
@Override
public void run() {
try {
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
} catch (Exception useDefault) {
}
ResponsiveGUI o = new ResponsiveGUI();
JFrame f = new JFrame("Responsive GUI");
f.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
f.setLocationByPlatform(true);
f.setContentPane(o.getUI());
f.pack();
f.setVisible(true);
}
};
SwingUtilities.invokeLater(r);
}
}
