Source 
pub unsafe extern "C" fn OH_ArkUI_PointerEvent_SetStopPropagation(
    event: *const ArkUI_UIInputEvent,
    stopPropagation: bool,
) -> i32
Available on crate feature api-12 only.
Expand description

Sets whether to stop event propagation. This API only applies to scenarios raw input events are received, such as when [NODE_ON_TOUCH] is used for touch event handling. It cannot be used with ArkUI_UIInputEvent objects obtained from gesture events through [OH_ArkUI_GestureEvent_GetRawInputEvent].

§Arguments

  • event - Pointer to the current UI input event.

  • stopPropagation - Whether to stop event propagation.

§Returns

  • Returns the status code of the execution. If 0 is returned, the setting is successful. If 401 is returned, the execution fails. The possible cause of the failure is that the event parameter is abnormal, such as a null pointer.
