Plugin help for QML > .PY communication

[Hurde 0]

Hey everyone,

 

I thought i'll go on an adventure and create my own plugin.

 

whilst stumbling through the examples and pretty much no documentation, I came upon an example whereof I don't know how it's mechanics work.

 

i found the following from https://github.com/fieldOfView/Cura-MeasureTool

 

// MeasureTool.qml

property var pointA: UM.ActiveTool.properties.getValue("PointA")

#MeasureTool.py

self.setExposedProperties("PointA", "PointB", "Distance", "ActivePoint", "FromLocked", "SnapVerticesSupported", "SnapVertices")

 

somehow this is linked together.  But I can't seem to find out how.

 

Could someone explain how it works?

 

In the end. All i want to do is to pass a Bool from .QML to the .py
