Python in #QGIS: Potenziale nutzen, Sicherheit wahren 💪

🖥️ Wo wird #Python-Code in QGIS gespeichert, wann ausgeführt – und welche Risiken bringt das mit sich?

Johannes Kröger & Isabelle Korsch geben gleich auf der #FOSSGIS2026 Antworten:
• Struktur: Plugins, Makros, Aktionen & Ausdrucksfunktionen
• Ladeverhalten & gezielte Steuerung
• Risiken & Best Practices für den Arbeitsalltag

QGIS DevTools — Déboguer et développer ses plugins plus efficacement
Le développement de plugins QGIS peut parfois être fastidieux : recharger le plugin, déboguer, inspecter l’interface, exécuter des scripts, etc.
C’est là que DevTools pour QGIS (NextGIS) entre en jeu — un ensemble d’outils conçus pour rendre le développement plus fluide, interactif, rapide et ergonomique.

For #PyQGIS raster masters:

use QgsRasterLayer.as_numpy() to get your raster layer as numpy array.

This was silently added in QGIS v3.40,
thus no one seems to know!

This week, I've been working on a Docker image which ships the migration script PyQt5 to PyQt6 made by @CabiecesJ and @florent001 to automatically check @QGIS plugins against Qt6. It's now usable locally as in a CI.

I've updated the relevant wiki: https://github.com/qgis/QGIS/wiki/Plugin-migration-to-be-compatible-with-Qt5-and-Qt6

Nicolas Godet l'a fait, lui.
Il a également configuré correctement #VSCode pour le développement de #PyQGIS. Oui, correctement, sans vilain script batch des 90s.

Il partage sa méthodologie gratuitement, bénévolement. Pour le bonheur d'intellisense.

We are promoting a new edition of our training "Introduction to #pyQGIS (Python for #QGIS) programming", that will take place next September as remote/synchronous sessions. Goal of the training is to introduce trainees to how to extend #QGIS capabilities by creating scripts and plugins/extensions with their own graphical interface. #NaturalGIS is a QGIS approved certifying organization https://changelog.qgis.org/en/qgis/certifyingorganisation/natural-gis-lda/ For further details follow https://www.naturalgis.pt/pyqgis_training.html

I'm very excited that the revision of my #unigis #salzburg module on automating #gis workflows with #qgis and #python is taking shape.

This will be the 3rd revision of the module. And all assignments will be #PyQGIS scripting/ programming challenges.

Fingers crossed that I'm doing a good enough job at guiding the students through what may be their first programming experience 🤞

Today's detective work: figuring out all the tiny details to create different layer styles in #PyQGIS:

1⃣ QgsSingleSymbolRenderer with data-defined properties
vs
2⃣ QgsGraduatedSymbolRenderer with QgsArrowSymbolLayer

I think data-defined properties will be my way to go
