Question

我正在尝试使用Python Gtk3调整窗口大小，但我需要扩展Notebook对象以填充主窗口。我怎么能让笔记本填满窗户的其余部分呢？

像这样：

这是我的代码：

#!/usr/bin/python
# coding=utf-8
import gi
gi.require_version('Gtk', '3.0')
from gi.repository import Gtk, Gdk


class SearchDialog(Gtk.Dialog):

  def __init__(self, parent):
      Gtk.Dialog.__init__(self, "Something", parent,
          Gtk.DialogFlags.MODAL, buttons=(
          Gtk.STOCK_NEW, Gtk.ResponseType.OK,
          Gtk.STOCK_CANCEL, Gtk.ResponseType.CANCEL))

      self.set_default_size(400, 600)

      box = self.get_content_area()

      label = Gtk.Label("Insert text you want to search for:")
      box.add(label)

#        self.entry = Gtk.Entry()
#        box.add(self.entry)

      self.main_area = Gtk.Stack()
      self.main_area.set_transition_type(Gtk.StackTransitionType.SLIDE_LEFT_RIGHT)

      self.main_area.set_transition_duration(1000)

      self.entry = Gtk.Entry()
      self.main_area.add_titled(self.entry, "entry_name", "Entry Url")

      self.labelS = Gtk.Label()
      self.label_txt = """<big><i> label here</i></big>"""
      self.labelS.set_markup(self.label_txt)
      self.labelS.set_line_wrap(True)
      self.main_area.add_titled(self.labelS, "label_name", "How Scan will Start")

      self.our_stackSwitcher = Gtk.StackSwitcher()
      self.our_stackSwitcher.set_stack(self.main_area)

      box.add(self.our_stackSwitcher)
      box.add(self.main_area)

      self.show_all()


class MyWindow(Gtk.Window):

    def __init__(self):
        Gtk.Window.__init__(self, title="Desktop app title")

        self.set_default_size(1000, 648)
        vbox = Gtk.Box(orientation=Gtk.Orientation.VERTICAL)
        self.add(vbox)

        vbox.add(Hbox1)

        vbox.add(Hbox2)
        Hbox3 = Gtk.Box(orientation=Gtk.Orientation.HORIZONTAL)
        vbox.add(Hbox3)

        vbox.add(Hbox4)
