python gtk填充TreeView中的ListStore

Question

嘿，我是新来的，有个问题我正在尝试创建一个带有ListStore的TreeView。ListStore应该从另一个类获得一个列表，但我似乎无法填充我的ListStore。

这是代码

TreeView和ListStore：labelDB=gtk。标签（"数据库"）

    self.storeDB = gtk.ListStore(str, str, int, str)
    rentexDB = gtk.CellRendererText()
    colDB1 = gtk.TreeViewColumn('Name', rentexDB)
    colDB2 = gtk.TreeViewColumn('URL', rentexDB)
    colDB3 = gtk.TreeViewColumn('Bitrate', rentexDB)
    colDB4 = gtk.TreeViewColumn('Format', rentexDB)
    self.fillStore()
    pageDB = gtk.TreeView(model=self.storeDB)
    pageDB.append_column(colDB1)
    pageDB.append_column(colDB2)
    pageDB.append_column(colDB3)
    pageDB.append_column(colDB4)
    showData.append_page(pageDB, labelDB)

和fillStore:

def fillStore(self):
    dataInStore = self.record.useDB()
    if dataInStore is not None:
        self.storeDB.clear()
        for row in dataInStore:
            #print row
            self.storeDB.append(row)
    return self.storeDB

当我打印行的时，我可以看到要存储在ListStore中的列表但是ListStore总是空的

我希望有人能帮助我，请

下面是一个演示应用程序：

#!/usr/bin/env python3
from gi.repository import Gtk

class Demo:
    def __init__(self):
        self.window = Gtk.Window()
        self.window.set_default_size(640, 480)
        self.window.connect('delete-event', self.on_app_exit)
        scrolledwindow = Gtk.ScrolledWindow()
        self.window.add(scrolledwindow)
        self.liststore = Gtk.ListStore(str, str, int, str)
        # You need to use self.fillStore() instead.
        self.liststore.append(['Debian', 'i386', 0, 'ok'])
        self.liststore.append(['Fedora', 'amd64', 1, 'ok'])
        self.liststore.append(['Ubuntu', 'i386', 2, 'ok'])
        treeview = Gtk.TreeView(model=self.liststore)
        scrolledwindow.add(treeview)
        names = ('Name', 'URL', 'Bitrate', 'Format')
        for i in range(4):
            renderer_text = Gtk.CellRendererText()
            column = Gtk.TreeViewColumn(names[i], renderer_text, text=i)
            treeview.append_column(column)
    def fillStore(self):
        pass
    def run(self):
        self.window.show_all()
        Gtk.main()
    def on_app_exit(self, widget, event=None):
        Gtk.main_quit()

if __name__ == '__main__':
    demo = Demo()
    demo.run()
