Python GTK - 在小部件之间切换 - 在小部件中嵌入树或 window

Question

我有一个带有菜单栏和 3 个菜单项的 window。前两项应该允许用户在主 "window"（对于 java 我会说面板）和日志 "window" 之间切换。我习惯在 swing 中使用卡片布局 - java。但我想在 python gtk 中做同样的事情。

第二个问题是 - 我如何显示一棵树并在树旁边，比方说 4 个按钮。树的代码是 - http://www.pygtk.org/pygtk2tutorial/sec-CellRenderers.html#cellrendererfig

希望您能给我一些提示，告诉我如何处理上述问题：/

我的 window 目前看起来像这样：

目前我的代码是这样的：

import pygtk
pygtk.require("2.0")
import gtk, gobject

class PyApp(gtk.Window):

    def __init__(self):
        super(PyApp, self).__init__()

        self.set_title("Utilities Testing Tool")
        self.set_size_request(700, 500)
        self.modify_bg(gtk.STATE_NORMAL, gtk.gdk.Color(6400, 6400, 6440))
        self.set_position(gtk.WIN_POS_CENTER)

        mb = gtk.MenuBar()


        treem = gtk.MenuItem("Tree Window")
        treem.connect("button_press_event", self.open_tree_widget)
        logm = gtk.MenuItem("Log Window")
        logm.connect("button_press_event", self.open_log_widget)
        exit = gtk.MenuItem("Exit")
        exit.connect("button_press_event", gtk.main_quit)
        mb.append(treem)
        mb.append(logm)
        mb.append(exit)


        self.vbox = gtk.VBox(False, 2)
        self.vbox.pack_start(mb, False, False, 0)

        self.add(self.vbox)

        self.connect("destroy", gtk.main_quit)
        self.show_all()

    def open_tree_widget(self, arg0, arg1):
        print("tree")


    def open_log_widget(self,  arg0, arg1):
        print("log")

    def replace_widget(self, current, new):
        """
        Replace one widget with another.
        'current' has to be inside a container (e.g. gtk.VBox).
        """
        container = current.parent
        assert container # is "current" inside a container widget?

        # stolen from gazpacho code (widgets/base/base.py):
        props = {}
        for pspec in gtk.container_class_list_child_properties(container):
            props[pspec.name] = container.child_get_property(current, pspec.name)

        gtk.Container.remove(container, current)
        container.add(new)

        for name, value in props.items():
            container.child_set_property(new, name, value)    

PyApp()
gtk.main()

我同时阅读了 public pygtk 教程的某些部分，并编写了以下解决方案。

该解决方案包含由 class gtk.table 继承的两个 classes。

如果按下其中一个按钮来切换 window，则会调用方法 "replace_widget"。 "replace_widget" 获取两个参数，当前小部件和想要的小部件。请参见以下代码。我希望这个答案可以帮助一些遇到同样问题的人。感谢您的回答。
