[Qgis-user] Convert QML style files

Hello, I have few shapefiles that have QML style files. The symbology of shapefiles works perfectly fine within QGIS. However, when I add these shapefiles to ArcGIS online map, the symbology does not get translated. Is there a way to convert the QML style symbology to ESRI compatible style?

Re: [Qgis-user] processAlgorithm vs processFeature?

If your algorithm works on each feature independently, processFeature() is preferred. If you need to work with layers, you need to use processAlgorithm(). I demonstrate this with an example at https://spatialthoughts.com/2019/04/05/geodesic-buffers-in-qgis/ On Mon, 23 Aug 2021 at 10:25 PM, C

Re: [Qgis-user] Labels

Sure. Use the Expression builder. You get to it by press the ∑ button to the righ of the value drop down list. Then enter the fields in double quotes concatenated with +, for example: "Town" + "Date" If you need a space or other text, enclose it in single quotes. For example: "Town" + '

Thanks Nyall, I figured it was that because I could place the string “Length” in a column. I thought it would work in the field calculator with something like ‘“‘ || @thelenghtstring || ‘“‘ but obviously, it does not. Thank ps for the precision. Nicolas Cadieux https://gitlab.com/njacadieux

I am a bit late, and Charles already provided a working solution, but don't forget the extremely useful function eval. The function as is will compare fieldname to fieldname (returning true) and then try to concatenate the string '2' to it... @NamelengthField != @NamelengthField || '2' Try

[Qgis-user] processAlgorithm vs processFeature?

I discovered that it looks like there is another way to deal with processing algorithms. Rather than use processAlgorithm it looks like I can use prepareAlgorithm & processFeature. I have always used processAlgorithm and then iterated through the features. Is processFeature just as quick as using

You could use a geometry generator symbol style. Not sure of the best expression for it but even something like if("fid"=1,buffer(collect($geometry),0),0) should work On Mon, 23 Aug 2021, 16:25 Dario C, wrote: > Hi, > I have road layer with several pieces of geometry. > is there any way to

In the project properties you can configure your default styles for the various geometry and data types using style definitions from the style manager. These styles are stored in the symbology-style.db which is specific to each user profile. You can then save your configured project into the user
