Module feature 

Names of IR features a target lists in TargetDescriptor::features.

Constants

ACCORDION_LAYOUT

Accordion: columns of which one is open at a time.

ADAPTIVE_IMAGES

BOUND_SHORTCUTS

Shortcuts that follow state, such as shortcut: app.keys.open and Shortcut(key: app.keys.back): the runtime reads the text each time it changes; without it a shortcut is a literal.

DELAYED_APPEAR

An entrance after a delay, including the first mounted frame.

DIALOG_WINDOWS

Window(role: dialog) shown modally over the primary window; without it a dialog is a window of its own.

MENU_BAR
