/**
|
|
* Common base class for top-level items (a.k.a. "parts") in the template editor sidebar. Subclasses
|
|
* should exist for all subclasses of {@see ve.dm.MWTransclusionPartModel}:
|
|
* - {@see ve.dm.MWTemplateModel}
|
|
* - {@see ve.dm.MWTemplatePlaceholderModel}
|
|
* - {@see ve.dm.MWTransclusionContentModel}
|
|
*
|
|
* This is inspired by and meant to replace {@see OO.ui.DecoratedOptionWidget} in the context of the
|
|
* template dialog. Also see {@see OO.ui.ButtonWidget} for inspiration.
