jdialog

问题 I have a JDialog window. I need to make it modal, but the parent is not Java window, but native Windows OS window. Is it possible? 回答1: No, you can't. You cannot even achieve reference not only to native windows but even to windows created by java application running in other JVM. But you can create dummy window (Window, not Frame or JFrame), set its size as 0 and use it as an parent to any dialog. I do not know what is your concrete problem but sometimes the way I mentioned may help. 来源：

问题 So I'm trying to make a simple dialog where the user can input some information...

问题 I am creating a dialog for showing a progress of files' copying. What I want to do is to completely remove dialog's icon image. I created such kind of dialogs before providing an application's instance of FrameView as an argument for JDialog 's constructor like this: public class MyAppView extends FrameView { // ... @Action public void showOptionsDialog() { // Creating modal options' dialog JDialog optionsDialog = new JDialog(this, true); // ... } } So, as I can see, I need a parent component

问题 How does one create a custom modal JDialog that can be used as an internal dialog? For use in FullscreenExclusiveMode.

问题 I create two dialogs: DialogA: setVisible(true) called only once. DialogB: setVisible(true) and setAlwaysOnTop(true) called every 1,5 sec Windows: Each call to dialogB.setAlwaysOnTop(true) brings dialogA AND dialogB to the front. OSX: Each call to dialogB.setAlwaysOnTop(true) brings only dialogB to the front. (Expected Behaviour) Test Case (Windows): 1 I start the application from my IDE. 2 I see DialogA. 3 I click in the IDE and DialogA disappears. 4 After one second DialogA and DialogB will

问题 I am using the following code to fade-in a JDialog with a javax.swing.Timer : float i = 0.0F; final Timer timer = new Timer(50, null); timer.addActionListener(new ActionListener() { @Override public void actionPerformed(ActionEvent e) { if (i == 0.8F){ timer.stop(); } i = i + 0.1F; setOpacity(i); } }); timer.start(); The Dialog is nicely faded-in with the desired effect but at last, an IllegalArgumentException Occurs saying that: The value of opacity should be in the range [0.0f .. 1.0f] But

问题 I have an application with an abstract class that extends JDialog . The class as an abstract void onClose() , and, in the class's constructor, the following code is added: addWindowListener(new WindowAdapter() { @Override public void windowClosed(WindowEvent e) { onClose(); } } The event is fired when expected, but then a strange thing happens. When a concrete extension of this class has code to create a new JDialog in the onClose() method, and this JDialog 's defaultCloseOperation is JDialog

问题 is there a way to make the dialog from ProgressMonitor modal? EDIT: The ProgressMonitor class in JAVA API will bring a dialog which is on the top but not Modal. User still has access to the background GUI.

As an implementation detail

问题 I have a question regarding the border around an undecorated JDialog using the Metal L&F . Look at this picture to see the border that is on this window: I'm trying to figure out how to either get rid of or change the color of the blue border around the very outside of the JDialog .

Thanks! 回答1: You need to change the Border
