[QGIS-Developer] Creating & loading Qt6 resource files for python plugins

[Etienne Trimaille]

Hi,

Quite a few developers, like me as well, are not using resource files
anymore. It's more simple, no need to compile resource files etc. It's just
my opinion.

You can just use pathlib, for instance :

   - Define a variable at the root of your plugin :

DIR_PLUGIN_ROOT = Path(__file__).parent

Then call it when you want with an icon :
QIcon(str(DIR_PLUGIN_ROOT / "resources/icons/logo.svg"))

Regards,
