joptionpane

I have a button on a JFrame that when clicked I want a dialog box to popup with multiple text areas for user input. I have been looking all around to try to figure out how to do this but I keep on getting more confused. Can anyone help? If you don't need much in the way of custom behavior, JOptionPane is a good time saver. It takes care of the placement and localization of OK / Cancel options, and is a quick-and-dirty way to show a custom dialog without needing to define your own classes. Most of the time the "message" parameter in JOptionPane is a String, but you can pass in a JComponent or

I have this Runnable window: EventQueue.invokeLater(new Runnable(){ @Override public void run() { op = new JOptionPane("Breaktime",JOptionPane.WARNING_MESSAGE); dialog = op.createDialog("Break"); dialog.setAlwaysOnTop(true); dialog.setModal(true); dialog.setDefaultCloseOperation(JDialog.DISPOSE_ON_CLOSE); dialog.setVisible(true); } }); Is it possible that I can have a timer here to close this within 1 or 2 minutes instead of clicking the OK button? Yes, the trick would be to get the Timer started before you call setVisible ... public class AutoClose02 { public static void main(String[] args) {

Please can someone tell me if there is a convenient way of prevent JOptionPane from closing upon clicking OK unless the conditions for user input fields are met? Or do I have no choice but to use JFrame ? My validation logic so far. Doesn't seem to work because the buttons are one-time clickable to some reason... final JDialog dialog3 = new JDialog(OmniGUI.getFrame(), "Create new Node - id:" + newNodeID); dialog3.setContentPane(theOPane); dialog3.setDefaultCloseOperation(JDialog.DO_NOTHING_ON_CLOSE); theOPane.addPropertyChangeListener(new PropertyChangeListener(){ public void propertyChange

Can someone explain to me why I lost the selection (set by setSelected() ) for JCheckBox when I put the JOptionPane into the ItemListener ? Is this a bug ? It is curious, that if this process is delayed with invokeLater() , setSelected() works correctly as I expected. from SSCCE import javax.swing.*; import java.awt.*; import java.awt.event.*; public class ComponentEventDemo extends JPanel implements ComponentListener, ItemListener { private static final long serialVersionUID = 1L; private JFrame frame; private JTextArea display; private String newline = "\n"; private JTextField field1; public
