Dear Developers,
I like to use a GPKG to store and visualize statistical information on
files in a remote sensing data cube. The GPKG contains three layers:
1. ard_data - a table with all kinds of information but without geometries
2. ard_tiles - a table with polygon geometries.
3. ard_data_by
Hi Gerald,
you may use "from importlib import reload" to reload the packages that
have been changed.

Dear Lars,
this looks like your plugin's __init__.py (that one that contains the
"def classFactory(iface)") want's to import the LIFA_ejdexplorer before
it's location is added to the PYTHONPATH
You may need something like:
sys.path.append('folder to LIFA_ejdexplorer')
before the classFactor

Hi Luke,
to my experience the "RuntimeError: wrapped C/C++ object of type

has been deleted by a parent class.
This is often a QgsMapLayerStore, for example the
QgsProject.instance().mapLayerStore(), from which a layer gets

Dear all,
it seems that QGIS has big problems to load rasters with a higher number
of bands. De facto users cannot visualize data from hyperspectral
satellites like EnMAP, DESIS or the CHIME in a responsive way.
In my case I tried to load an AVIRIS-NG image (425 bands x 1673 height x

Hi Luke,
it looks like your QGISenv.bat does not add the QGIS internal plugin
folder to the PYTHONPATH.
You may use something like:
set PYTHONPATH=^

%OSGEO4W_ROOT%\apps\%QGIS_ENV%\python\plugins;^
%PYTHONPATH%
where OSGEO4W_ROOT is the path to where yo
Hi Michael,
call "import processing" before "import qgis.processing"
Calling "import processing" will monkey-patch the request "run(...)" to
qgis.processing.
This is automatically done when starting the Desktop QGIS.

what is mean is something like:

Hi Raymond,
you need to ensure that your provider saves a python reference on your
TestAlgorithm2() (which you probably already do).
After its set of algorithms has changed (i.e. refresh, addAlgorithm(s)
etc.) it needs to emit the algorithmsLoaded signal.

Hi Aron,
with the EnMAP-Box plugin we are confronted with missing PIP packages
quite often. Therefore we implemented a "PIP Package Installer"

Dear Developers,
to implement a QgsExpressionFunction I like to access the "layer" from a
QgsExpressionContext "context".
Using the C++ API this can be done with the QgsExpressionUtils:

context->variable( QStringLiteral( "layer" ) ), p
