UB1ActionKeyWidget

Overview

• Widget that automatically displays the key icon bound by an InputAction's MappingName. Auto-switches by keyboard/gamepad input type, auto-detects Chord Actions (combo keys) and shows modifiers, and auto-refreshes when key customization changes. Example: SetActionByMappingName("ToggleMapAction") -> keyboard mode: [M] -> gamepad mode: [Y] + [X] (Chord Action auto-detected).

Function	Parameters	Returns	Description
HasValidKey	-	boolean	Checks whether the currently displayed key is valid.
RefreshKeyDisplay	-	-	Manual refresh.
SetActionByMappingName	InMappingName: string	-	Sets the action by MappingName. Auto-looks up that MappingName's key and Chord Action (modifier) from the IMC.
SetDirectKey	InKey: FKey, InModifier: EB1KeyboardModifierType	-	Displays the icon by specifying an FKey directly (shown directly without an Action lookup). Switches bUseMappingName to false and shows that key's icon. Specifying a modifier shows a combo key (e.g. [Ctrl] + [R]).
