没有Gtk.main()，GTK3中的python解释器中不会显示窗口 [英] Window doesn't show in python interpreter in GTK3 without Gtk.main()

问题描述

在GTK2中，我喜欢即时"在解释器(ipython或纯python)中构建gui，并实时观察到这样的变化:

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:

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

这将导致显示一个我可以向其添加对象的窗口.

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

我之所以改用Gtk3，部分是因为这是未来，部分是因为我有时会使用Glade，而现在的Glade只是Gtk3.使用GTK3进行相同操作时，不显示窗口:

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:

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

A，最后一行之后没有窗口.直到:

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

>>> Gtk.main()

我什至尝试:

>>> win.show_now()

什么都没做.

有什么想法如何在GTK3中实时构建?

Any ideas how to build in real time in GTK3?

谢谢

推荐答案

我尝试使用以下一种方法处理未决事件:

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

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

，它看起来具有相同的行为.它不是很方便，但是您仍然可以在解释器中做一些工作.

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

或者，如果您正在开发Gtk应用程序，则pdb.set_trace仍然可以正常工作，并且如果需要的话，还可以让您调试回调.

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.
