Functions

Name	Description
ArkUI_KeyEventType OH_ArkUI_KeyEvent_GetType (const ArkUI_UIInputEvent *event)	Obtains the type of a key event.
int32_t OH_ArkUI_KeyEvent_GetKeyCode (const ArkUI_UIInputEvent *event)	Obtains the key code from a key event.
const char * OH_ArkUI_KeyEvent_GetKeyText (const ArkUI_UIInputEvent *event)	Obtains the key value from a key event.
ArkUI_KeySourceType OH_ArkUI_KeyEvent_GetKeySource (const ArkUI_UIInputEvent *event)	Obtains the type of input device that triggers a key event.
void OH_ArkUI_KeyEvent_StopPropagation (const ArkUI_UIInputEvent *event, bool stopPropagation)	Stops a key event from bubbling upwards or downwards.
ArkUI_KeyIntension OH_ArkUI_KeyEvent_GetKeyIntensionCode (const ArkUI_UIInputEvent *event)	Obtains the intention code associated with a key event.
uint32_t OH_ArkUI_KeyEvent_GetUnicode (const ArkUI_UIInputEvent *event)	Obtains the Unicode value of a key event. Non-space basic Latin characters in the 0x0021-0x007E range are supported. Characters with a value of 0 are not supported. In the case of key combination, this API returns the Unicode value of the key corresponding to the key event.
void OH_ArkUI_KeyEvent_SetConsumed (const ArkUI_UIInputEvent *event, bool isConsumed)	Sets whether a key event is consumed in the key event callback.
void OH_ArkUI_KeyEvent_Dispatch (ArkUI_NodeHandle node, const ArkUI_UIInputEvent event)	Dispatches a key event to a specific node.
