JOptionPane opening another JFrame
- by mike_hornbeck
So I'm continuing my fight with this : http://stackoverflow.com/questions/2923545/creating-java-dialogs/2926126 task. Now my JOptionPane opens new window with envelope overfiew, but I can't change size of this window. Also I wanted to have sender's data in upper left corner, and receiver's data in bottom right. How can I achieve that ?
There is also issue with OptionPane itself. After I click 'OK' it opens small window in the upper left corner of the screen. What is this and why it's appearing ?
My code:
import java.awt.*;
import java.awt.Font;
import javax.swing.*;
public class Main extends JFrame {
private static JTextField nameField = new JTextField(20);
private static JTextField surnameField = new JTextField();
private static JTextField addr1Field = new JTextField();
private static JTextField addr2Field = new JTextField();
private static JComboBox sizes = new JComboBox(new String[] { "small", "medium", "large", "extra-large" });
public Main(){
JPanel mainPanel = new JPanel();
mainPanel.setLayout(new BoxLayout(mainPanel, BoxLayout.Y_AXIS));
getContentPane().add(mainPanel);
JPanel addrPanel = new JPanel(new GridLayout(0, 1));
addrPanel.setBorder(BorderFactory.createTitledBorder("Receiver"));
addrPanel.add(new JLabel("Name"));
addrPanel.add(nameField);
addrPanel.add(new JLabel("Surname"));
addrPanel.add(surnameField);
addrPanel.add(new JLabel("Address 1"));
addrPanel.add(addr1Field);
addrPanel.add(new JLabel("Address 2"));
addrPanel.add(addr2Field);
mainPanel.add(addrPanel);
mainPanel.add(new JLabel(" "));
mainPanel.add(sizes);
String[] buttons = { "OK", "Cancel"};
int c = JOptionPane.showOptionDialog(
null,
mainPanel,
"My Panel",
JOptionPane.DEFAULT_OPTION,
JOptionPane.PLAIN_MESSAGE,
null,
buttons,
buttons[0]
);
if(c ==0){
new Envelope(nameField.getText(), surnameField.getText(), addr1Field.getText()
, addr2Field.getText(), sizes.getSelectedIndex());
}
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
pack();
setVisible(true);
}
public static void main(String[] args) {
new Main();
}
}
class Envelope extends JFrame {
private final int SMALL=0;
private final int MEDIUM=1;
private final int LARGE=2;
private final int XLARGE=3;
public Envelope(String n, String s, String a1, String a2, int i){
Container content = getContentPane();
JPanel mainPanel = new JPanel();
mainPanel.setLayout(new BoxLayout(mainPanel, BoxLayout.Y_AXIS));
mainPanel.add(new JLabel("John Doe"));
mainPanel.add(new JLabel("FooBar str 14"));
mainPanel.add(new JLabel("Newark, 45-99"));
JPanel dataPanel = new JPanel();
dataPanel.setFont(new Font("sansserif", Font.PLAIN, 32)); //set size from i
mainPanel.setLayout(new BoxLayout(mainPanel, BoxLayout.Y_AXIS));
mainPanel.setBackground(Color.ORANGE);
mainPanel.add(new JLabel("Mr "+n+" "+s));
mainPanel.add(new JLabel(a1));
mainPanel.add(new JLabel(a2));
content.setSize(450, 600);
content.setBackground(Color.ORANGE);
content.add(mainPanel, BorderLayout.NORTH);
content.add(dataPanel, BorderLayout.SOUTH);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
pack();
setVisible(true);
}
}
