遵循有關(guān)容器的官方教程。我有以下代碼import gigi.require_version('Gtk', '3.0')from gi.repository import Gtkclass MainWindow(Gtk.Window):    def __init__(self):        Gtk.Window.__init__(self, title="test")        grid = Gtk.Grid()        self.add(grid)        button1 = Gtk.Button(label="Button 1")        button2 = Gtk.Button(label="Button 2")        button3 = Gtk.Button(label="Button 3")        button4 = Gtk.Button(label="Button 4")        button5 = Gtk.Button(label="Button 5")        button6 = Gtk.Button(label="Button 6")        grid.add(button1)        grid.attach(button2, 1, 0, 2, 1)        grid.attach_next_to(button3, button1, Gtk.PositionType.BOTTOM, 1, 2)        grid.attach_next_to(button4, button3, Gtk.PositionType.RIGHT, 2, 1)        grid.attach(button5, 1, 2, 1, 1)        grid.attach_next_to(button6, button5, Gtk.PositionType.RIGHT, 1, 1)win = MainWindow()win.connect("destroy", Gtk.main_quit)win.show_all()Gtk.main()當(dāng)我運行它時一切都很好但是，如果我調(diào)整它的大小，網(wǎng)格將不會隨主窗口一起調(diào)整大小。任何指針如何使網(wǎng)格調(diào)整大小？
