Dialog Box Tutorial
Introduction:-
A Dialog window is an independent
subwindow meant to carry temporary notice apart from the main Swing Application
Window. Message dialog box is used to display
informative messages to the user.
To create simple, standard
dialogs, you have to use the JOptionPane class.
Here is the code that creates and shows
it:
JOptionPane.showMessageDialog(frame,
"Example of Dialog Window.");
Some Methods of JOptionPane class to create Dialog box:-
JOptionPane class is available in the
javax.swing.*; package. This class provide various types of message
dialog box as follows:
1. showMessageDialog()
Displays a modal dialog with one button,
which is labeled "OK" (or the localized equivalent). You can easily
specify the message, icon, and title that the dialog displays. Here are some
examples of using showMessageDialog:
1. Default title and icon:-It is used to
create an information-message dialog titled "Message”.
JOptionPane.showMessageDialog(frame,"method
1.");
2.Following method is used to create a
message dialog with given title and messageType.:-
static void showMessageDialog(Component
parentComponent, Object message, String title, int messageType);
2.ShowConfirmDialog():
And the last or third method is the showConfirmDialog() which asks the
user for confirmation (Yes/No) by displaying message. This method return a
numeric value either 0 or 1. If you click on the "Yes" button then
the method returns 1 otherwise 0.
Syntax:-
static int showConfirmDialog(Component
parentComponent, Object message)
3.ShowInputDialog():
It is used to show a question-message dialog requesting input from the
user parented to parentComponent.
Syntax:-
static String showInputDialog(Component
parentComponent, Object message)
//program to illustrate the use of Showmessage Dialog method
import javax.swing.*;
public class Message {
JFrame f;
Message(){
f=new JFrame();
JOptionPane.showMessageDialog(f,"This is the example of showMessageDialog.");
}
public static void main(String args[])
{
new Message();
}
}
Output:-
//program to illustrate the use of ShowConfirm Dialog method
import javax.swing.*;
public class Message {
JFrame f;
Message(){
f=new JFrame();
JOptionPane.showConfirmDialog(f,"This is the example of showConfirmDialog.");
}
public static void main(String args[])
{
new Message();
}
}
Output:-
//program to illustrate the use of showInputDialog method
import javax.swing.*;
public class inputdialog {
JFrame f;
inputdialog()
{
f=new JFrame();
String name=JOptionPane.showInputDialog(f,"Give any suggestion!");
}
public static void main(String[] args) {
new inputdialog();
}
}
Output :-
