Choose the theme

cellucid_layout_theme_set.Rd

Show the app light or dark.

Usage

cellucid_layout_theme_set(viewer, theme)

Arguments

viewer

A viewer cellucid_view() or cellucid_serve() returned.

theme

One of "light", "dark". Required.

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 its outcome (what it did, as names, counts and ids), or NULL when it had nothing to report; request$step is the history step it made.

Details

The viewer's action layout.theme.set (Layout). It changes the viewer's layout: one step of the viewer's history, labelled as R's, undone like any other. The state it can change: layout.

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

Examples

if (interactive() && requireNamespace("SeuratObject", quietly = TRUE)) {
  data("pbmc_small", package = "SeuratObject")
  viewer <- cellucid_view(SeuratObject::UpdateSeuratObject(pbmc_small))
  request <- cellucid_layout_theme_set(viewer, theme = "light")
  print(request)
  # cellucid_action_result(request) waits for its outcome.
  cellucid_stop(viewer)
}
