在python中,使用Gtk 3.0,我尝试使用笔记本获取Windows。在此笔记本中,有一些扩展器。每个扩展器将包含一个树视图。

经过一番搜索,我有这段代码:

import gi
gi.require_version('Gtk', '3.0')
from gi.repository import Gtk

class MyWindow(Gtk.Window):

    def __init__(self):
        Gtk.Window.__init__(self, title="Hello World")

        # Create liststore which will be contained within treeview
        # liststore has 3 rows and 3 columns
        self.store = Gtk.ListStore(str, str, float)
        self.store.append(["string1.1", "string1.2", 1.0])
        self.store.append(["string2.1", "string2.2", 2.0])
        self.store.append(["string3.1", "string3.2", 3.0])

        # Create treeview which will be contained within one expander
        # treeview has 3 columns and contain liststore
        self.tree = Gtk.TreeView(self.store)
        for i, column_title in enumerate(["col1", "col2", "col3"]):
            renderer = Gtk.CellRendererText()
            column = Gtk.TreeViewColumn(column_title, renderer, text=i)
            self.tree.append_column(column)

        # Addind a callback to selection_changed event of treeview
        select = self.tree.get_selection()
        select.connect("changed", self.on_tree_selection_changed)

        # Create expander which will be contained within one notebook page
        # Adding treeview inside expander
        self.page1 = Gtk.Expander()
        self.page1.set_border_width(10)
        self.page1.add(self.tree)

        # Create notebook and adding expander inside first page
        self.notebook = Gtk.Notebook()
        self.add(self.notebook)
        self.notebook.append_page(self.page1, Gtk.Label('Page1'))

        self.Window = Gtk.Window()
        self.Window.add(self.notebook)

        self.show_all()

    def on_tree_selection_changed(self, selection):
        model, treeiter = selection.get_selected()
        if treeiter != None:
          print("You selected", model[treeiter][0])

win = MyWindow()
win.connect("delete-event", Gtk.main_quit)
win.show_all()
Gtk.main()


我无法在扩展器中显示treeview。
但没有扩展器,则显示树视图。

我在Ubuntu 12.04上工作,并使用python ihm.py命令启动程序。

有人可以向我解释为什么它不起作用?

最佳答案

您要将笔记本添加到父级两次。删除线

self.Window.add(self.notebook)


这对我有用。很奇怪您没有收到关于此的错误消息。
