Welcome to the NeXus Constructor wiki!

The Nexus Constructor uses a Qt-QML UI through the 'Qt for Python' (aka 'PySide2') bindings. It is an official set of bindings produced by Qt.

This wiki consists of three main sections:

• Developer Notes - a resource that aims to compile and explain noteworthy features (or quirks) of the program so that developers know what they're working with. Consult this to get a general view of the program.
• QML Guide - a guide/tips and tricks resource for "pure" QML. Consult this if you are trying to do something that is purely concerned with the views and has no interaction with Python.
• Qt for Python Guide - a tutorial/tips and tricks resource for using QML with Python. Consult this if the issue you are addressing with involves (or might be benefited by) the views communicating with Python.
