Published Monday May 14th, 2018 | 7 Comments on QML and Qt for Python interaction
Posted in Qt for Python

Besides QtWidgets for desktop applications, Qt has another UI technology, QML. Today, I would like to show how QML interacts with Qt for Python, roughly based on the tutorial example declarative/extending/chapter3-bindings. First, let’s have a look at the typical boiler plate code for loading a .qml file. We instantiate a QGuiApplication and a QQuickView. We set […]
