How do I link PyCharm to PyQt4?

I use PyCharm 2016.2.3 (32-bit), Python 2.7.12 (32-bit), PyQt4-4.11.4-gpl-Py2.7-Qt4.8.7-x32, Windows 7 Home Premium.

I would be grateful for the procedure to link PyCharm to PyQT4. I'm not a techie.

I linked to the Python interpreter using File > Settings > Project Interpreter, by simply pointing to "python.exe"

For PyQt4, I can see the folder in

C:\Python27\Lib\site-packages\PyQt4

But which file do I actually "point to"?

Thanks.

Solution

Here's how I solved this for Python 2.7.12 and Python 3.4.4:

File > Settings > Project > Project Interpreter > <Python version>

Double-click setup tools

In Search, type PyQt4

In left pane, don't select PyQT4. This will give the error

Could not find a version that satisfies the requirement PyQt4

Instead, select PyQt4_windows_whl. For me, this was successful.

Test in editor by typing:

from PyQt4 import QtGui

As soon as I typed

from P

PyQt4 appeared in the dropdown.

As soon as I typed

from PyQt4 import Q

QtGui appeared in the dropdown.

I'm no expert, so I don't know if these tests are conclusive.
