Expand description

@brief Registers the surface lifecycle and touch event callbacks.

@since 8 @version 1.0

Fields§

§OnSurfaceCreated: Option<unsafe extern "C" fn(component: *mut OH_NativeXComponent, window: *mut c_void)>

Called when the surface is created.

§OnSurfaceChanged: Option<unsafe extern "C" fn(component: *mut OH_NativeXComponent, window: *mut c_void)>

Called when the surface is changed.

§OnSurfaceDestroyed: Option<unsafe extern "C" fn(component: *mut OH_NativeXComponent, window: *mut c_void)>

Called when the surface is destroyed.

§DispatchTouchEvent: Option<unsafe extern "C" fn(component: *mut OH_NativeXComponent, window: *mut c_void)>

Called when a touch event is triggered.
