Loading QPA plugin from Python

[A Former User]

Hello,

does anybody know how to load a QPA plugin from inside Python?

I couldn't find any documentation for this, only how to load the plugin with qml ... -plugin ... directly, googling this problem only yields searches regarding errors.

I've already tried the QPluginLoader, which didn't work:

engine = QQmlApplicationEngine()
engine.rootContext().setContextProperty("synthesizer", synthesizer)
engine.load(Path(__file__).resolve().parent / "main.qml")
tuio = QPluginLoader("TuioTouch") # <- this is the name of the plugin, don't know what else to put here
tuio.load() # -> doesn't load the plugin :(

and then tried to load the plugin via environment variable from inside Python, which didn't work either.

There really should be an easy way to get this working, no?

Update: setting the environment variable from outside Python works! But still, is there no more comfortable way to set this programmatically?

I don't know about the whole area, but you can set an environment variable as the first statement in a Python program if that is what you need for the later code?
