jdialog

I'm trying to display a JDialog in Windows. How do I show a JDialog (like JFrame ) on my Windows taskbar? A dialog itself cannot have a task bar entry, but you can construct a frame that does not have any visible effect and use it as a parent for the dialog. Then it will look like the dialog has a task bar entry. The following code shows you how to do it: class MyDialog extends JDialog { private static final List<Image> ICONS = Arrays.asList( new ImageIcon("icon_16.png").getImage(), new ImageIcon("icon_32.png").getImage(), new ImageIcon("icon_64.png").getImage()); MyDialog() { super(new

I have created a modal JDialog box with a custom drawing on it and a JButton. When I click the JButton, the JDialog box should close and a value should be returned. I have created a function in the parent JFrame called setModalPiece, which receives a value and sets it to a local JFrame variable. The problem is that this function is not visible from the JDialog box (even though the JDialog box has a reference to the parent JFrame). Two questions: 1) Is there a better way to return a value from a JDialog box to its parent JFrame? 2) Why can't the reference to the JFrame passed to the JDialog be

I know setVisible(false) , dispose() ,but they can't really close a JDialog. When I have the other thread stop, the thread of the JDialog still runs. And I can't use System.exit(0) ,because the other thread needs run for a while. Following the code, I finally resolve the problem by System.exit(0) at the end of the program. public class CsUpdateCtrl { /** * 升级service */ private CsUpdateService service; private CsUpdateCtrl() { this.service = (CsUpdateService) RmiUtil.getBean(RmiUtil.Service.csupdate); } private static final Logger log = Logger.getLogger(CsUpdateCtrl.class.getName()); public

I need to remove the maximize and minimize buttons from a JFrame . Please suggest how to do this. import java.awt.event.WindowAdapter; import java.awt.event.WindowEvent; import javax.swing.JDialog; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JPanel; public class Dlg extends JDialog { public Dlg(JFrame frame, String str) { super(frame, str); addWindowListener(new WindowAdapter() { public void windowClosing(WindowEvent evt) { System.exit(0); } }); } public static void main(String[] args) { try { Dlg frame = new Dlg(new JFrame(), "No min max buttons"); JPanel panel =

Does it make sense to use setVisible(false) on a dialog and reuse it later or is safer to call dispose() every time and to make a new JDialog. What about memory leaks with setVisible(false)? EDIT: My Question isn't so much about quitting the application. More about Dialogs that have the main frame as parent and are opened and closed during the application life time. E.g. let's say my applications has about 10 dialogs that display different data every time I open them. Should I reuse the instances and use setVisible() or should I make a new Dialog every time and dispose() them on closing. I

I have a dialog for a client-GUI that asks for the IP and Port of the server one wants to connect to. I have everything else, but how would I make it so that when the user clicks "OK" on my dialog box, that it runs something? Here's what I have so far: import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import javax.swing.JDialog; import javax.swing.JOptionPane; import javax.swing.JTextField; public class ClientDialog { JTextField ip = new JTextField(20); JTextField port = new JTextField(20); GUI gui = new GUI(); Client client = new Client(); JOptionPane optionPane; public
