Python Gtk+ development in Linux using Eclipse + PyDev, Unresolved import: Gtk

Question

I just tried to write my first Gtk+ program using python in linux mint with Eclipse + PyDev, but I met this error in PyDev, Unresolved import: Gtk

program source code: http://python-gtk-3-tutorial.readthedocs.org/en/latest/introduction.html

from gi.repository import Gtk

win = Gtk.Window()
win.connect("delete-event", Gtk.main_quit)
win.show_all()
Gtk.main()

error shown as below:

Program can run. I checked PYTHONPATH in PyDev, I think it's right. enter image description here

How can I fix this problem?

By the way, could you give some advice about nice free IDE for Python & Gtk+ development in Linux?

@jadkik94 Yes, it can run in terminal by python command too. — Gino, Feb 14 '13 at 16:03
From the command line, after importing `Gtk` see what `Gtk.__path__` is and if it's in Pydev's PYTHONPATH. — jadkik94, Feb 14 '13 at 16:26
@jadkik94 Gtk.__path__ is /usr/lib/girepository-1.0/Gtk-3.0.typelib I have alread add /usr/lib/girepository-1.0 into PYTHONPATH, but not fix this problem. — Gino, Feb 14 '13 at 16:31

Go to Window->Preferences and add "gi" to "Forced Builtins" (see screenshots).
You should try Glade for GTK3 gui design (see screenshot).
See final result screenshot.
You could also use Sublime Text 3.

this should be the accepted answer, as it actually solves the issue and add code completion. – gcscaglia Oct 06 '15 at 13:39

same issue: https://stackoverflow.com/a/11418828/1040891

In Gtk+ 3 Python bindings to binary modules are generated dynamically using *.typelib databases. The dynamic importer for accessing all the modules is located in gi.repository. PyCharm cannot detect these modules using its code insight, because they require special handling.

Note: IPython can detect and handle these modules

Problem is explained, but not solved: what "special handling" the `gi.repository` modules need to remove the false error mark and enable so autompletion? – MestreLion Nov 07 '13 at 11:10

You must use Python 3.x.

Eclipse->Windows->Preferences->PyDev->Python Interpreter*->Advanced Auto-Config->/usr/share/python3.3**->Ok->Apply->Ok

*If using Python, instead of Jython or IronPython

**If Python 3.3 installed, otherwise try python3, but I've not tested.
