Display Behavior Grammar

A set of verbs to manipulate the display of an attribute.

Usage

hide(config, item = get_context(), ...)

display(config, item = get_context(), ...)

hidden(config, item = get_context())

displayed(config, item = get_context())

Arguments

config

the config list.

item

the name (id) of the item group.

...

the name of the attribute(s) to manipulate.

Value

a list (setters) or a character vector (getters).

Details

hide() and display() are setter functions to tune attribute's behavior. hidden() and displayed() are getter functions to quickly access the attributes to hide or display in the item table.

When item is set in the parent frame, then the attribute can be skipped in the function call.
