[Qgis-developer] various problems during a course
Hi all. Today, during a course, I spotted several problems: - the plugin Elevation does not take into account the proxy setting, so it does not work (known problem[0]) and it locks QGIS, forcing a restart; I suggest to fix it or, if impossible, to deprecate it - opening a - the plugin CSW client does not connect (I'm behind a proxy, do not know what's going wrong) with error: Error connecting to server geocat.ch: [same for others] urlopen error timed out - the tile scale apparently does not work - invert color map (in raster properties) option seem bugged: the flag is unchecked when closing the window - Rasterlite layers, e.g. http://download.gfoss.it/TrueMarble/TrueMarble-2km.sqlite are extremely slow to open (I remember a while ago they were surprisingly fast); I noticed it uses only one CPU out of four, BTW Feedback welcome.

[Qgis-developer] WPS plugin not connecting (proxy?)
Hi all. I set up the proxy in qgis, and everything is working, except for the Elevation plugin (as I already wrote) and WPS plugin: do they both use another method for accessing the web, bypassing the proxy setting? All the best. -- http://faunalia.it/pc ___ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer
Re: [Qgis-developer] Load SQLite table into QGIS
I was able to create the spatialite geometry/geometryless tables outside QGIS
and now what I would want is to be able to insert data in C++ into tables with
and without geometry.
Any ideas?

Hi,
I know how to Load a spatiaLite spatial table into
QGIS,
but I can't find how to load a non spatial table (ie
simple SQLite table).
I've read the pyqgis cookbook, and QGs API, but didn't
find any answer.
This should work:
vlayer = QgsVectorLayer('dbname=/data/gis/test.sqlite
table=mytable', 'mytable', 'spatialite')

Re: [Qgis-developer] WPS plugin not connecting (proxy?)
Hi Paolo, I remember having some difficulties too with proxy settings and the WPS plugin. I did not look at the code, but the WPS plugin honors the http_proxy env var setting. Also, I'm wondering whether it should always honor the QGis proxy settings (nor the http_proxy env var) : for my use case, I'm trying to reach a WPS server inside my LAN, while I need proxy settings to access the web (plugin installation, etc...). Maybe each server configured in the plugin should have an associated local/remote boolean setting. Strange as it can be, for my LAN case, the GetCapabilities and DescribeProcess calls works, but http_proxy must be correctly unset only for ExecuteProcess request to work correctly.

Re: [Qgis-developer] WPS plugin not connecting (proxy?)
Hi Paolo Yes you are right. The WPS-Client isnt able to connect through proxy.

All the best. Elevation uses the python httplib, which requires you to first set up a connection to the proxy and then do a query with the full http://blah/blah URL, instead of setting up a connection to the web server and then getting just the path. A change to Elevation.py to use urllib (which is imported, but not used) works for me - but I'm not sure if its getting my proxy settings from Qgis's settings or from my shell's proxy settings. Either way, it works: Around Line 85: url = http://maps.google.com/maps/api/elevation/json?locations=; + str(pt[1])+,+str(pt[0])+sensor=false u = urllib.urlopen(url) jsonresult = u.read() urllib2 might be another possible option. I've CC'd Steffen, the elevation plugin author in on this. Barry ___ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer

A better approach would be to use Qt classes for network I/O (i.e. QNetworkRequest and friends) together with QgsNetworkAccessManager that knows qgis proxy settings - then the plugin does not have to worry about proxies. Additionally those Qt classes provide a convenient interface using signals and slots.

I also wanted to know if it was possible to string the sql commands to

[Qgis-developer] Installed Qgis on Ubuntu - what do I do next?
Hi, I installed the qgis Server and apache (ubuntu 11.04) and now I don't know how to start the qgis webserver.

What should I do as first steps after installing? if working correctly, the address http://localhost/cgi-bin/qgis_mapserv.fcgi should return ServiceExceptionReport version=1.3.0ServiceException code=OperationNotSupportedPlease check the value of the REQUEST parameter/ServiceException/ServiceExceptionReport Then just create a project in QGIS (use absolute paths) and in the project properties configure the parameters in the WMS server tab. Create a folder in /usr/lib/cgi-bin/ and copy into it your QGIS project and a copy of qgis_mapserv.fcgi your server address will be http://localhost/cgi-bin/myprojectfolder/qgis_mapserv.fcgi cheers -- Giovanni -- ___ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer
