我試圖在Python 2.7中用扭曲來製作一個小型的GTK 3 irc客戶端。目前，我有一個非常基本的客戶端，可以成功連接到irc網絡並在主文本區域顯示一些內容。我目前正在努力實現多通道支持，但是在連接通道時填充包含通道的條目的GtkListBox似乎不起作用。無法將項目添加到我的Gtk.Window之外的GtkListBox
的Python代碼低於：

據我所知，添加到GtkListBox代碼將在窗口中工作，但不是在扭曲ircclient類。
任何幫助表示讚賞！
顯示的ListBoxItem中可以包含一個鏈接到'main_view.glade'某處的情況下？沒有它的例子不會運行。 – Glyph 2015-02-08 00:13:21
哦，當然是'server.glade'。 – Glyph 2015-02-08 00:13:50
這段代碼的一個主要問題是你正在執行'Gtk.main（）'作爲主循環，然後在回調中嘗試執行'reactor.run（）'。這最多可以創建一個嵌套的主循環，該循環由Gtk支持，但不是Twisted所支持的，並且會導致'dialog_response_cb'永久掛起。這可能會造成奇怪的行爲。 – Glyph 2015-02-08 00:18:56
