How do I add items to a gtk.ComboBox created through glade at runtime?
提问by Bernard
I'm using Glade 3 to create a GtkBuilder file for a PyGTK app I'm working on. It's for managing bandwidth, so I have a gtk.ComboBox for selecting the network interface to track.
我正在使用 Glade 3 为我正在处理的 PyGTK 应用程序创建 GtkBuilder 文件。它用于管理带宽，所以我有一个 gtk.ComboBox 用于选择要跟踪的网络接口。
How do I add strings to the ComboBox at runtime? This is what I have so far:
如何在运行时向 ComboBox 添加字符串？这是我到目前为止：
self.tracked_interface = builder.get_object("tracked_interface")
self.iface_list_store = gtk.ListStore(gobject.TYPE_STRING)
self.iface_list_store.append(["hello, "])
self.iface_list_store.append(["world."])
self.tracked_interface.set_model(self.iface_list_store)
self.tracked_interface.set_active(0)
But the ComboBox remains empty. I tried RTFM'ing, but just came away more confused, if anything.
但是 ComboBox 仍然是空的。我尝试过 RTFM，但如果有的话，我会更加困惑。
Cheers.
干杯。

Hey, I actually get to answer my own question!
嘿，我实际上可以回答我自己的问题！
You have to add gtk.CellRendererText into there for it to actually render:
您必须将 gtk.CellRendererText 添加到其中才能实际呈现：
self.iface_list_store = gtk.ListStore(gobject.TYPE_STRING)
self.iface_list_store.append(["hello, "])
self.iface_list_store.append(["world."])
self.tracked_interface.set_model(self.iface_list_store)
self.tracked_interface.set_active(0)
# And here's the new stuff:
cell = gtk.CellRendererText()
self.tracked_interface.pack_start(cell, True)
self.tracked_interface.add_attribute(cell, "text", 0)
Retrieved from, of course, the PyGTK FAQ.
当然，从PyGTK FAQ 中检索。

Or you could just create and insert the combo box yourself using gtk.combo_box_new_text(). Then you'll be able to use gtk shortcuts to append, insert, prependand removetext.
或者您可以使用gtk.combo_box_new_text(). 然后您将能够使用 gtk 快捷方式来附加、插入、前置和删除文本。
combo = gtk.combo_box_new_text()
combo.append_text('hello')
combo.append_text('world')
combo.set_active(0)
box = builder.get_object('some-box')
box.pack_start(combo, False, False)
