使用Eclipse的GridBagLayout中的AlertBox

Question

我希望在Eclipse中使用gridbaglayout单击“提交”按钮时，显示诸如警报框之类的消息。

我已经完成了网格窗格的工作，这是完美的。我不确定在gridbaglayout中可以将哪种类型的消息视为警报消息。

    button.addActionListener {
        public void actionPerformed(ActionEvent e) {

            if(nameField.getText().isEmpty()) {
                showAlert(Alert.AlertType.ERROR, grid.getScene().getWindow(), "Form Error!", "Please enter your name");
                return;
            }
            if(emailField.getText().isEmpty()) {
                showAlert(Alert.AlertType.ERROR, grid.getScene().getWindow(), "Form Error!", "Please enter your email id");
                return;
            }
            if(detailedField.getText().isEmpty()) {
                showAlert(Alert.AlertType.ERROR, grid.getScene().getWindow(), "Form Error!", "Please enter a password");
                return;
            }


            showAlert(Alert.AlertType.CONFIRMATION, grid.getScene().getWindow(), "Save  Successful!","Congratulations!!!    " + nameField.getText() + "\n" +"   File has Submitted Successfully!!");

            showAlert(Alert.AlertType.CONFIRMATION, grid.getScene().getWindow(), "Save  Successful!","Congratulations!!!    " + nameField.getText() + "\n" + "   File has Email Successfully!!");

            showAlert(Alert.AlertType.CONFIRMATION, grid.getScene().getWindow(), "Save  Successful!","Congratulations!!!    " + nameField.getText() + "\n" + "   File has Print Successfully!!");

        }
    };
