Java Swing Standard dialog box implementation

This article describes the implementation of the Swing Standard dialog box, you need friends can refer to the copy code code as follows:

package test001;


import java.awt.event.ActionEvent;


import Java.awt.event.ActionListener;


import Javax.swing.JButton;


import Javax.swing.JFrame;


import Javax.swing.JOptionPane;


import Javax.swing.JToolBar;


public class Testjoptionpane implements actionlistener{


private JFrame JF = new JFrame ("Standard dialog Box test");


/**


* @param args


*/


public static void Main (string[] args) {


//TODO auto-generated method stub


new Testjoptionpane (). Createui ();


}


public void Createui () {


JToolBar JTB = new JToolBar ();


string[] s = {"Error", "Exit Confirmation 1", "Exit Confirmation 2", "Warning", "Input", "select"};


int size = s.length;


jbutton[] button = new Jbutton[size];


for (int i = 0; i < size; i++) {


Button[i] = new JButton (s[i));


Button[i].addactionlistener (this);


Jtb.add (Button[i]);


}


Jf.add (JTB, "North");


jf.setsize (350, 150);


jf.setlocation (400, 200);


jf.setdefaultcloseoperation (jframe.exit_on_close);


jf.setvisible (TRUE);


}


@Override


public void actionperformed (ActionEvent e) {


//TODO auto-generated method stub


String s = E.getactioncommand ();


if (s.equals ("error")) {


Joptionpane.showmessagedialog (NULL, "error message to display---",


"false hint", joptionpane.error_message);


}


Else if (s.equals ("Exit confirmation 1")) {


int result = Joptionpane.showconfirmdialog (null,


"Do you want to save the program before launch?" ");


if (result = = joptionpane.yes_option) {


System.out.println ("Save Program---");


system.exit (0);


}


else if (result = = joptionpane.no_option) {


system.exit (0);


}


}


Else if (s.equals ("Exit confirmation 2")) {


int result = Joptionpane.showconfirmdialog (null, "Do you want to save the program before exiting?) ");


if (result = = joptionpane.yes_option) {


System.out.println ("Save Program---");


system.exit (0);


}


else if (result = = joptionpane.no_option) {


system.exit (0);


}


}


Else if (s.equals ("Warning")) {


object[] options = {"Continue", "undo"};

}


}


Else if (s.equals ("input")) {

if (name!= null) {


System.out.println ("Name:" + name);


}


}


Else if (s.equals ("select")) {


object[] possiblevalues = {"Sport", "politics", "economy", "culture"};

"Choose One", "Input", joptionpane.information_message, NULL,


PossibleValues, possiblevalues[0]);


String choose = (string) SelectedValue;


if (choose!= null) {


System.out.println ("you choose:" + choose);


}


}


}
