PyGtk: окно переполнения виджета

Question

Моя карта Champlain переполняет мое окно GtkWindow, как показано на прикрепленном скриншоте. Я не смог найти никого с подобной проблемой в Интернете.

Я сделал графический интерфейс в Glade и оставил одну пустую панель, чтобы я мог заполнить ее в коде GtkChamplain.Embed виджет для отображения карты. Он работал почти нормально, пока я не установил размер запроса Embed чтобы предотвратить проглатывание карты при изменении размеров окна.

Я не хотел, чтобы это случилось:

Конечно, я могу обойти это, установив ограничение на то, насколько маленькое окно может уменьшаться и насколько может увеличиваться левая сторона панели. Я бы предпочел сделать это соответствующим образом, установив Embedразмер запроса. Кто-нибудь знает, почему это происходит или как сделать это правильно?

Вот мой полный код.

# -*- coding: utf-8 -*-

import gi
gi.require_version('Champlain', '0.12')
gi.require_version('GtkChamplain', '0.12')
gi.require_version('GtkClutter', '1.0')
from gi.repository import GtkClutter, Clutter
GtkClutter.init([])  # Must be initialized before importing those:
from gi.repository import GObject, Gtk, Champlain, GtkChamplain, Pango

class UserInterface:

    def __init__(self):
        builder = Gtk.Builder()
        builder.add_from_file('zahori.glade')

        self.client_list = builder.get_object("client-list")
        self.main_window = builder.get_object("main-window")
        self.main_panel = builder.get_object("main-panel")
        self.client_treeview = builder.get_object("client-treeview")
        self.main_window = builder.get_object("main-window")
        self.status_label = builder.get_object("status-label")

        self.map_embed = GtkChamplain.Embed()
        self.map_embed.set_size_request(550, 300)
        self.main_panel.add(self.map_embed)

        self.main_window.connect("destroy", Gtk.main_quit)
        self.main_window.show_all()


UserInterface()
Gtk.main()

Answer 1

Я мог бы опубликовать это слишком рано. Я быстро нашел ответ, когда обнаружил child_set_property() метод GtkContainer,

Установив...

self.main_panel.add(self.map_embed)
self.main_panel.child_set_property(self.map_embed,"resize",False)
self.main_panel.child_set_property(self.map_embed,"shrink",False)

Мой интерфейс начал вести себя должным образом. Если не требуется иное, я сохраняю здесь свои вопросы и ответы на случай, если кто-то столкнется с подобной проблемой.
