[Qgis-user] Changes in Python versions on QGIS 3.18
Hello, I am not sure this is the appropriate mailing list to send this, but here it goes. I have noticed that QGIS 3.18 for Windows has shipped with Python 3.9, after having updated to 3.8 just a couple of versions ago. As a plugin developer, it becomes very difficult to track things and make sure plugins are up-to-date in the face of changing Python versions, especially when the move is to a bleeding edge version such as 3.9 right now. What channels should I be plugged into to learn about these changes and offer input before they happen? Is there such a channel?

[Qgis-user] Saving Linestring layer to SQLite
Hi, I have been struggling for a few days now with importing Linestring layers into Spatialite. Every time I save the layers into a sqlite file, they are automatically converted to MultiLinestring, even though they are perfectly normal Linestring files in all other formats I tested (SHP and TAB). Has anybody come across this before?

[Qgis-user] Function deprecated
Hi,
I am writing a plugin to style a set of layers and I am getting a
message of deprecation on QGIS 2.14
I read the documentation but I was honestly not able to decipher it. Can
somebody give me a pointer on how the following *bold* lines of code would
change?
*symbolList = layer.rendererV2().symbols()*...
linkMeta = symLyrReg.instance().symbolLayerMetadata('SimpleMarker')
link = linkMeta.createSymbolLayer(linkStyle)
link.setDataDefinedProperty('angle', 'if ("Dirn" =1,90,270)')
*link.setDataDefinedProperty('size', 'if ("Dirn" = 1,1.8,if ("Dirn" =
3,1.8,0))')*
Thanks,
Pedro

[Qgis-user] Automatizing map making
Hi, I have been using QGIS for a few months now after almost a decade using Maptitude and TransCAD (from Caliper Corporation). Now that I already know how to get around pretty well with QGIS, I want to use it to production of series of maps (from a few dozens to hundreds at a time). My current problem is to make simple maps with graduated style and fixed classes for several different fields on the database. Looking at the PyQGIS documentation helped a bit, but I got several errors like NameError: name 'QtGui' is not defined and for many other names/libraries in the sample code I used, so I'm pretty sure that I have something missing that was not mentioned in the documentation or that I missed. Further, I'm interested in making maps with fields that are not in the database, so I need to make a join too (which is not mentioned anywhere in the documentation I saw). I would imagine that there is a way to open a project, change something (like the fields for the graduate rendenring), update the map composer and save the jpg, but I didn;t see anything like that... Did anybody face a situation like this? Any recomendations? Any sample code you could share? Thanks for the help, Pedro UC Irvine PS - Sorry for posting in two lists, but I really have no idea where to send this e-mail. ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user
