This is an example add-on for Orange3. Add-on can extend Orange either in scripting or GUI part, or in both. We here focus on the GUI part and implement a simple (empty) widget, register it with Orange and add a new workflow with this widget to example tutorials.
To install the add-on, run
python setup.py install
To register this add-on with Orange, but keep the code in the development directory (do not copy it to Python's site-packages directory), run
python setup.py develop
After the installation, the widget from this add-on is registered with Orange. To run Orange from the terminal, use
python -m Orange.canvas
The new widget appears in the toolbox bar under the section Example.
