Module: Teek::UI::TabValidator Private

Defined in:
lib/teek/ui/tab_validator.rb

Overview

This module is part of a private API. You should avoid using this module if possible, as it may be removed or be changed in the future.

A tab's own contract: it must be declared directly inside a ui.tabs. Only reachable via direct Node/Document manipulation, since WidgetDSL#tab already refuses to run outside a ui.tabs block - the same defense-in-depth GridValidator.check_stray_cell does for grid. Composed into WidgetValidators via :tab's own WidgetType#validator (see widget_types/tab.rb).
