ViewRegistry handles the association between model and view
types in Atom. We call this association a View Provider. As in, for a given
model, this class can provide a view via ::getView, as long as the
model/view association was registered via ::addViewProvider
If you’re adding your own kind of pane item, a good strategy for all but the simplest items is to separate the model and the view. The model handles application logic and is the primary point of API interaction. The view just handles presentation.
Note: Models can be any object, but must implement a
if they are to be displayed in a Pane
View providers inform the workspace how your model objects should be presented in the DOM. A view provider must always return a DOM node, which makes HTML 5 custom elements an ideal tool for implementing views in Atom.
You can access the
ViewRegistry object via
workspaceElement = atom.views.getView(atom.workspace)
textEditor = atom.workspace.getActiveTextEditor() textEditorElement = atom.views.getView(textEditor)
pane = atom.workspace.getActivePane() paneElement = atom.views.getView(pane)
Add a provider that will be used to construct views in the workspace’s view layer based on model objects in its model layer.
Constructor Function for your model. If a constructor is given, the
Factory Function that is passed an instance of your model and must return a subclass of

Get the view associated with an object in the workspace.
If you’re just using the workspace, you shouldn’t need to access the view layer, but view layer access may be necessary if you want to perform DOM manipulation that isn’t supported via the model API.
The view associated with the object is resolved using the following sequence
HTMLElement? If true, return the object.
elementwith a value which is an instance of

jqueryproperty? If true, return the root DOM element (i.e.
If no associated view is returned by the sequence an error is thrown.
The object for which you want to retrieve a view. This can be a pane item, a pane, or the workspace itself.
Returns a DOM element.
