explorer_ui(id)

explorer(input, output, session, .values, .root_node_r,
  .explorer_classes = list(),
  .addable_explorer_classes_r = shiny::reactive("__group__"),
  .visible_explorer_classes_r = shiny::reactive("__group__"),
  .display_header = TRUE, .label_list = label_explorer(),
  .state = list())

Arguments

id	The module's id.
input, output, session	Called by callModule.
.values	The .values list.
.root_node_r	A reactive returning an object of class ExplorerNode. This needs not necessarily to be the root node of an object of class ExplorerTree.
.explorer_classes	A list of objects of class ExplorerClass.
.addable_explorer_classes_r	A reactive returning a character vector containing the ids of explorer classes that are addable to the explorer.
.visible_explorer_classes_r	A reactive returning a character vector containing the ids of explorer classes that are displayed to the user. Group nodes are always displayed.
.display_header	If TRUE, the navigation header is displayed, otherwise it is not.
.label_list	A list created with label_explorer containing labels for all buttons used inside the explorer module.
.state	A list which is passed to every explorer class server function. Use this list to implement special behaviour of an explorer class dependent on conditions outside of the explorer.

contextmenued_node_r	An object of class ExplorerNode. This is the node, which has been last contextmenued.
