Question

我使用Glade创建了custom GtkFileChooserDialog。 Modal属性已标记。我还有GtkFileChooserButton使用此GtkFileChooserDialog作为其对话框：

class ImgChooserBttWithCapture(Gtk.FileChooserButton):
    """
    The custom Gtk.FileChooserButton and Gtt.FileChooserDialog with a button for call capture app
    """

    def __init__(self, cap_app_path):
        self.builder = Gtk.Builder.new_from_file(
            UIS_PATH + 'images_chooser_dialog.xml')
        self.chooser_dialog = self.builder.get_object('icd_photo_chsrdialog')

        super().__init__(dialog=self.chooser_dialog)
        self.cap_app_path = cap_app_path
        self.set_title('Selecione uma imagem')
        self.set_halign(Gtk.Align.START)
        self.set_valign(Gtk.Align.FILL)
        self.set_hexpand(True)
        self.set_tooltip_text('Clique para escolher uma nova imagem')
        self.set_local_only(False)

        handlers = {'onCaptureButtonClicked': self._on_capture_button_clicked}

        self.builder.connect_signals(handlers)

    def _on_capture_button_clicked(self, button):

        try:
            subprocess.call([self.cap_app_path])
        except (subprocess.CalledProcessError, subprocess.TimeoutExpired, FileNotFoundError) as ex:

            self.builder.add_from_file(UIS_PATH + 'information_window.xml')
            msg_dialog = self.builder.get_object('iw_messagedialog')

            msg_dialog.set_title('Erro')
            msg_dialog.set_markup(
                '<span size="12000"><b>Não foi possível abrir o aplicativo</b></span>')

            msg_dialog.format_secondary_markup(
                'O aplicativo de captura não está disponível.\nVerifique o caminho para o aplicativo de caputura em configurações.\n' + '<span foreground="red"><u>' + str(ex) + '</u></span>')

            msg_dialog.set_property('message-type', Gtk.MessageType.ERROR)
            msg_dialog.set_transient_for(self.chooser_dialog)
            self.builder.get_object('iw_message_image').set_from_file(
                'views/uis/images/message_error.png')

            msg_dialog.run()
            msg_dialog.destroy()

但是，当我点击按钮时，对话框不是模态的，也就是说，我可以与其他窗口进行交互。

grabbing指针会为你工作吗？

class Demo {

    public static void main(String[] args) throws IOException {

        Person person = new Person(42);
        try {
            System.out.println(person.getMoney());
            person.addToShoppingBag(new Groceries(12));
            person.addToShoppingBag(new Groceries(20));
            person.addToShoppingBag(new Groceries(5));
            System.out.println(person.getMoney());
            System.out.println(person.getShoppingBag());
            person.getShoppingBag().add(new Groceries(1));
        } catch (UnsupportedOperationException e) {
            e.printStackTrace();
        }

        try {
            person.addToShoppingBag(new Groceries(66));
        } catch (IllegalStateException e) {
            e.printStackTrace();
        }
    }
}


class Person {

    private List<Groceries> shoppingBag = new ArrayList<>();
    private int money;

    public Person(int money) {
        this.money = money;
    }

    public List<Groceries> getShoppingBag() {
        List<Groceries> bag = ImmutableList.copyOf(shoppingBag);
        return bag;
    }

    public void addToShoppingBag(Groceries groceries) {

        if (0 > money - groceries.getPrice()) {
            throw new IllegalStateException("You have not enough money!");
        }

        shoppingBag.add(groceries);
        money -= groceries.getPrice();
    }

    private void addMoney(int amout) {
        money += amout;
    }

    public int getMoney() {
        return money;
    }
}

class Groceries {
    private int price;

    public Groceries(int price) {
        this.price = price;
    }

    public int getPrice() {
        return price;
    }

    @Override
    public String toString() {
        return "Groceries{" +
                "price=" + price +
                '}';
    }
}

GtkFileChooserDialog不作为模态
