Pop-up window in Java Swing

问题

Can someone suggest me how to implement a pop-up window in Java Swing. I want the pop-up window to be a modal window (user cannot return to the main window when the pop-up is open).

I tried doing it using JDialog but it allows only one widget for user input to be in it whereas I need multiple widgets. I may be wrong here but this is what I was able to do.

Appreciate your help.

回答1:

Use a JDialog. There is no restiction on what you can add, you can add whatever you want to a JDialog (exactly the same as when using a JFrame)

回答2:

1. Layout your widgets in a JPanel.

2. Use JOptionPane.showConfirmDialog with your panel as the message (with, for example, optionType JOptionPane.OK_CANCEL_OPTION).

3. Read user input from your panel's state when appropriate (for example, the call returns JOptionPane.OK_OPTION rather than JOptionPane.CANCEL_OPTION).
