Add preferences to be used in the KNIME 'Preferences' menu (like Marvin, R, ...) ?


I need to let user choose a specific path to run my node correctly and I think that preferences is the best way to do that. But where can I find the procedure to create these preferences for my node and to read it from my node ?


See e.g.

Or have a look at the source code of e.g. the CDK plugin (from the community contributions), which has its own preference page.
