I receive an import error when trying to import QStringList from the QGIS Python console (or when loading a custom plugin).
from PyQt4.QtCore import QStringList
Traceback (most recent call last):
File "<input>", line 1, in <module>
ImportError: cannot import name QStringList
I receive no error when using the same import from an ipython console or executing a standalone python script.
Python 2.7.5+ [GCC 4.8.1]
Please advise
You can't import QStringList in QGIS 2.x because we are using SIP bindings v2 which auto converts the types to Python types.
If you are buildling at a standalone app you should import qgis.core before import PyQt4 because PyQt4 will set the sip API to V1 before QGIS can set it to v2.
Long story short:
Do this:
from qgis.core import *
from PyQt4.QtCore import *
Not this:
from PyQt4.QtCore import *
from qgis.core import *
Because:
QGIS sets the API version to 2 or else PyQt4 will set it to version 1. Once it's set it can't be changed.
Version 2 is heaps better so use that.
Since I wasn't doing much 'exoticism' with that QStringList I tried to subsitute with a simple python List With Success.
try:
from PyQt4.QtCore import QStringList
except ImportError:
QStringList = list
then
ql = QStringList()
l = Global.getPG_connection().tableList
for item in l:
ql.append(item)
#Pass the QStringList to the QInputDialog
table, ok = QInputDialog.getItem(self, "something", "somewhere", ql )
allow proper construction of my QInputDialog.
