Pyside + QtMobility Location module on maemo SDK [solved]

ultimodruido

Hello everybody,
I'm using pyside to play around with the location module in the maemo SDK. unfortunately I don't get what I want. :)

I did install from extra-devel the following packages:
python-pyside 1.0.3-1maemo2
python-qtmobility 0.2.0-maemo11
libqtm-12-dev 1.2.0-0fn-frematle3

the problem occurs when in the program I try to create the QGeoServiceProvider in order to start the QGraphicsGeoMap.
@ def __init__my_map(self):
self.my_service_provider = Location.QGeoServiceProvider("nokia")
self.my_mapping_manager = self.my_service_provider.mappingManager()
self.my_mapview = Location.QGraphicsGeoMap (self.my_mapping_manager, self)
self.my_mapview.connectivityModeChanged(Location.QGraphicsGeoMap.HybridMode)@

Anyway this is the error message:
@self.my_service_provider = Location.QGeoServiceProvider("nokia")@

I did a @print dir(Location)@ and here is the result:
@['QGeoAreaMonitor', 'QGeoCoordinate', 'QGeoPositionInfo', 'QGeoPositionInfoSource', 'QGeoSatelliteInfo', 'QGeoSatelliteInfoSource', 'QNmeaPositionInfoSource', '_Cpp_Api', 'doc', 'file', 'name']@

it seems that pyside is not aware of everything that the location module knows... I'm sure I have QtMobility 1.2 because I could execute the QML mapviewer demo without any problem.
I've noticed that the pyside Qtmobility documentation refers to a version 0.2.2. Does everyone know if may be my problem is related to the fact that pyside is only at the vesion 0.2.0?
If "Yes" I think I have just to wait until the new version is released... if "no" is there a way to force pyside to connect to the qtmobility 1.2?

Thank you very much... have a nice weekend
Nicola

Could you report this on pyside bugzilla[1], we will check during the next week. Thanks

Hello Renato!
Thanks for your reply... I didn't have time yesterday to fill the bug. I will play again with python tomorrow afternoon and fill a detail bug with what I did discover (I did try more to solve the issue and discovered something else..)
I wasn't expecting to find a bug, I was more considering a wrong configuration from my side :)
Have a nice day

Hello
just for info, here is the bug report link
http://bugs.pyside.org/show_bug.cgi?id=917

I've just noticed that in the first post I missed actually the error message :) sorry, here it is:

@self.my_service_provider = Location.QGeoServiceProvider("nokia")
AttributeError: 'module' object has no attribute 'QGeoServiceProvider'@

And just for info here the error message that I receive while trying to load QtMobility 1.2 pugling within QDeclarativeView (instruction taken from "this link":http://www.developer.nokia.com/Community/Wiki/Latest_Qt_and_Qt_mobility_evaluation_on_Maemo

@class MainWindow(QtDeclarative.QDeclarativeView):

def __init__(self, parent=None):
    super(MainWindow, self).__init__(parent)
    self.setWindowTitle("test QML")
    self.engine().addImportPath('/opt/qtm12/imports')
    self.engine().addPluginPath('/opt/qtm12/plugins')
    self.setSource(QtCore.QUrl.fromLocalFile&#40;'qml/maemodrive/mapviewer.qml'&#41;)@

the error is while loading the modules:
@file:///home/maemo/MyDocs/Qt_stuff/maemodrive/qml/maemodrive/mapviewer.qml:2:2:
plugin cannot be loaded for module "QtMobility.location": Cannot load library

a detailed description is given into the bugreport.

Hi Renato,
I have a couple of question that maybe you can help me with:
I've been trying this also on the N900 available on the "remote device access" service from Nokia with the same result. The location module is reduced. Reading in the net I did discover that in N900 the QtMobility 1.2 is installed in parallel to the original given by nokia (1.0.2) That's why I guess pyside doesn't connect to the 1.2 version of qtmobility but to the official one.
In maemo forum they said that you need something like
@LD_LIBRARY_PATH=/opt/qtm12/lib yourexecutable@ to point to the new libraries. So my questions are:

Do you know a method there I can check the QtMobility version with pyside? Something like:
@print QtCore.qVersion()
print QtCore.version@
but that will return QtMobility instead of QtCore version?
In case it points to the official QtMobility release, is there a way to change this? Using
@LD_LIBRARY_PATH=/opt/qtm12/lib python2.5@ didn't work :(

Thanks a lot for your help
Nicola

Hi all,
I think I did find a partial solution.
the nokia N900 has QtMobility 1.0.2 officially installed with the PR1.3 update. Through the pachages libqtm-11-dev or libqtm-12-dev is it possible to install the QtMobility 1.1 or 1.2. These libraries are installed in parallel to the official one, that's why the official python-qtmobility package is linked to the 1.0.2 version.
In maemo extras-devel I found another package:
@python-qtmobility11@
these are the python libraries linked to the non official QtMobility 1.1 and as well can be installed in parallel to the official one. Infact the have been saved in:
@/opt/qtm11/lib/python2.5/site-packages/QtMobility/@
I did create a symbolic link to these libraries in the officialfolder in which python is looking for:

@cd /usr/lib/python2.5/site-packages/
ln -s /opt/qtm11/lib/python2.5/site-packages/QtMobility/ ./QtMobility11@
In these way I can access the QtMObility 1.1 from python:
@[sbox-FREMANTLE_X86: ~] > run-standalone.sh python2.5
Python 2.5.4 (r254:67916, May 17 2010, 21:11:14)
[GCC 4.2.1] on linux2
Type "help", "copyright", "credits" or "license" for more information.

from QtMobility11 import Location
print dir (Location)
['QGeoAddress', 'QGeoAreaMonitor', 'QGeoBoundingArea', 'QGeoBoundingBox',
'QGeoBoundingCircle', 'QGeoCoordinate', 'QGeoManeuver', 'QGeoMapCircleObject',
'QGeoMapData', 'QGeoMapGroupObject', 'QGeoMapObject', 'QGeoMapObjectInfo',
[...]
'QLandmarkRemoveRequest', 'QLandmarkSaveRequest', 'QLandmarkSortOrder',
'QLandmarkUnionFilter', 'QNmeaPositionInfoSource', '_Cpp_Api', 'doc', 'file', 'name']@

As you can see there is now access to all the Location classes from QtMobility 1.1
Hope this can help in case you encounter similar trouble, and hope somewhen also a package for the 1.2 version appears... unfortunately I'm not able to do it myself :)
