ActionBar

Action Bar: what it does​

A global footer that shows the current screen’s actions
(e.g., Back). It’s owned by CUI_BaseStack.

  • Lives inside CUI_BaseStack and auto-updates to show actions (e.g., Back, Apply, Confirm) from the topmost active widget.
  • Works for any menu you push as long as your screen doesn’t cover the bar visually.
  • Priority (typical): Modal > Overlay > Base — the topmost active stack feeds the bar.
  • Rule: Any screen you push can drive the bar if it doesn’t cover it

Do not RemoveFromParent for stack-managed screens.
Use Deactivate or Pop so actions unbind cleanly.

What it does​

  • Renders a row of action Buttons (icon + label).
  • Auto-updates to reflect the topmost active widget.
  • Swaps glyphs/labels when the input device changes
  • Input Data is set in Project Settings > Game > Common Input Settings > Input > Input Data
  • keyboard/gamepad see Content/KSynTemplate/UI/Input/InputDate_KSyn_Default

How actions get into the bar​

Each screen is a CommonActivatableWidget that registers actions when active:

  1. Set Is Back Handler to True
  2. Set Is Back Action Displayed in Action Bar to True
  3. Set Display in Action Bar to True
