While porting a plugin to QGIS3 I decided to also move all it’s threading infrastructure to QgsTasks. Here three possible variants to implement this.the first uses the static method QgsTask.fromFunction and is simpler to use. A great quick solution. If you want need control you can look at the second solution that subclasses QgsTask. In this solution I also show how to create subtasks with interdependencies. The third variant, illustrates how to run a processing Read more…

How to filter features in QGIS using the graphical processing modeler

This article describes a new algorithm for the processing modeler called feature filter algorithm. If you are already familiar with ETL concepts and the graphical modeler, you can directly jump to the section the feature filter algorithm. Building workflows for repetitive tasks When building workflows for simple or complex geodata infrastructures, one of the most common tasks one encounters is to extract some of the features and copy them to another destination. Sometimes they need Read more…
