没有Gtk.main（）的窗口不会在GTK3中的python解释器中显示

In GTK2, I enjoyed building a gui in the interpreter (ipython or plain python) "on the fly" and seeing the changes in real time like this:

在GTK2中，我喜欢在“动态”中在解释器（ipython或plain python）中构建一个gui并实时看到这些变化：

>>> import gtk
>>> win = gtk.Window()
>>> win.connect('delete-event', gtk.main_quit)
10L
>>> win.show_all()

Which will result in showing a window to which I could add objects.

这将导致显示一个我可以添加对象的窗口。

I'm changing to Gtk3 in part because it is the future and in part because I sometimes use Glade which now is only Gtk3. In doing the same with GTK3 DOESN'T show the window:

我正在改为Gtk3部分是因为它是未来，部分是因为我有时使用Glade，现在只有Gtk3。在使用GTK3时也不会显示窗口：

>>> from gi.repository import Gtk
>>> win = Gtk.Window()
>>> win.connect('delete-event', Gtk.main_quit)
13L
>>> win.show_all()

Alas, no window after that last line. It won't show until:

唉，在最后一行之后没有窗口。它将在以下情况下显示：

>>> Gtk.main()

I even tried:

我甚至尝试过：

>>> win.show_now()

Which did nothing.

哪个什么都没做。

Any ideas how to build in real time in GTK3?

有关如何在GTK3中实时构建的想法吗？

Thanks,

谢谢，

I tried to process pending events with the following one-liner:

我尝试使用以下单行处理待处理事件：

>>> while Gtk.events_pending(): Gtk.main_iteration()

and it looks to have the same behaviour. It's not so convenient, but you can still do some work in the interpreter.

它看起来有相同的行为。它不是那么方便，但你仍然可以在翻译中做一些工作。

Alternatively, if you're developing a Gtk application, pdb.set_trace will still work and let you debug callbacks if that's what you're looking for.

或者，如果您正在开发Gtk应用程序，pdb.set_trace仍然可以工作，如果您正在寻找的话，可以调试回调。
