显示Lis中空白行的PyGTK TreeView

Question

我试图在树状视图中显示数据库中的几行，但我得到的只是一些虚拟行，如下图所示。在

class SettingsDialog(gtk.Dialog):
    def __init__(self):
        gtk.Dialog.__init__(self, "Server Settings", self, gtk.DIALOG_MODAL | gtk.DIALOG_DESTROY_WITH_PARENT)

        # Instantiate ServerManager
        self.server_manager = ServerManager()

        # Create TreeStore for Server list
        self.liststore = gtk.ListStore(str, str)
        self.treeview = gtk.TreeView(self.liststore)

        # Create TreeViewColumns to display data
        cell = gtk.CellRendererText()
        col = gtk.TreeViewColumn("Name")
        col.pack_start(cell, True)
        self.treeview.append_column(col)

        cell = gtk.CellRendererText()
        col = gtk.TreeViewColumn("URL")
        col.pack_start(cell, True)
        self.treeview.append_column(col)

        self.vbox.pack_start(self.treeview)

        self.resize(500,350)
        self.set_position(gtk.WIN_POS_CENTER)
        self.show_all()

        self.load_server_list()


    def load_server_list(self):
        self.liststore.clear()
        servers = self.server_manager.list()
        for name, url in servers.iteritems():
                self.liststore.append([name, url])
        self.show_all()

从self.server_manager.list()返回的数据是有效的，完全添加到列表存储中。CellRenderers似乎有问题，但我找不到错误。在

必须在列上设置属性映射。例如，cellrenderer的文本属性值将显示在treeview单元格中。它取自数据模型上的值（self.liststore）。从中获取值的模型上的列号在属性映射中指定。在

## Take value for *text* attribute of the cell renderer from the model's 3rd column
col = gtk.TreeViewColumn(title, cellrenderer, text=2)
