Making a JDialog always on top of application

Question

I'm making a program that requires this jdialog box to always be focused and on top, ie: make the ding sound when i click on the parent window. here's what i have so far:

JDialog dialog = new JDialog();
//      dialog.setAlwaysOnTop(true);
        dialog.setSize(400, 220);
        dialog.setLocationRelativeTo(relativeTo); //relativeTo is the name of parent frame
        dialog.setVisible(true);
//      dialog.setModalityType(Dialog.ModalityType.APPLICATION_MODAL);
//      dialog.setModal(true);

(the commented things are those i have tried unsuccessfully...)

how would i make this dialog box ontop of the parent window? any help would be great! thanks

您需要设置对话框的所有者并将对话框设置为模态：

JDialog dialog = new JDialog(parentFrame, true); // owner, modal
