Creating a pop up box in Java

问题

I want to create a pop up box that is activated when I click a "Check" button. What it does is ask the user if they are sure about what they requested. If yes, it does the request. If no, it goes back to it's normal state.

I know what I said is a bit ambiguous but I want to create various types of pop up boxes.

So I was wondering is there a website that has generic pop up boxes with the code given?

I just need a simple code which I can expand on.

I think JOptionPane is what you want.

• showConfirmDialog: Asks a confirming question, like yes/no/cancel.
• showInputDialog: Prompt for some input.
• showMessageDialog: Tell the user about something that has happened.
• showOptionDialog: The Grand Unification of the above three.

A small example to get a Yes-No popup like you asked for would be:

if (JOptionPane.showConfirmDialog(null, "Are you sure about your request?", "Request", 
    JOptionPane.YES_NO_OPTION, JOptionPane.QUESTION_MESSAGE)
    == JOptionPane.YES_OPTION)
{
 //Do the request
}
else
{
 //Go back to normal
}

This solution, however, only works if you are using Swing.

You shoudl check JDialog to create your custom message dialogs or you can use standard message dialogs in JOptionPane.
