Read the views

Each open view: its name (what actions name it by), its title, the representation it shows, what it is coloured by, its filters and camera; the layout; the highlight pages with their groups.

Usage

cellucid_views_state(viewer)

Arguments

viewer

A viewer cellucid_view() or cellucid_serve() returned.

Value

A cellucid_action_request, at once and invisibly: the action is sent now, or when the viewer's channel opens. cellucid_action_result(request) returns what it read: a list of active (The name of the view the controls act on ("View N")), cameras_locked, highlights, layout, views. Cells in it are original positions (0-based rows of the dataset's obs).

Details

The viewer's action views.state (Views). It reads, and changes nothing: it makes no step of the history.

cellucid_act() sends any action by its type, and cellucid_action_result() collects its answer.
