java - 如果单击 JDialog 之外则 JDialog 关闭

Question

我只想在单击 JDialog 之外时关闭 JDialog

import javax.swing.JDialog;
import javax.swing.JLabel;


public class DialogFenster extends JDialog {

    public DialogFenster(String pText, String pTitel)
    {
        JDialog meinJDialog = new JDialog();
        meinJDialog.setTitle(pTitel);
        meinJDialog.setBounds(800, 500, 300, 70);
        meinJDialog.setModal(true);
        meinJDialog.add(new JLabel(pText));
        meinJDialog.setVisible(true);
    }
}

Answer 1

您可以使用WindowListener来了解对话框是否失去焦点:

JDialog dialog = new JDialog(frame, false);//false for not modal
dialog.addWindowListener(new WindowAdapter() {
    public void windowDeactivated(WindowEvent e) {
        dialog.dispose();
    }
});
dialog.setVisible(true);

但它必须是非模式对话框。如果它是模态的，windowDeactivated将永远不会被调用。
