Recently we undertook to standardize the redRCore Qt widget API. This is the API that is in the base package.
No elements of the API were removed, standard elements were pushed to be handled by the core widgetState container, which is the universal container for all redR core metawidgets.
All widgets accept the following as key word arguments;
widget - parent widget into which the widget controlArea will be placed.
label - most widgets accept and will display a label, possibly required, and possibly controlled using displayLabel
