Expand description
Raw window handle for Ohos NDK.
Fields (Non-exhaustive)§
This struct is marked as non-exhaustive
Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional
Struct { .. }
syntax; cannot be matched against without a wildcard ..
; and struct update syntax will not work.native_window: NonNull<c_void>
Implementations§
source§impl OhosNdkWindowHandle
impl OhosNdkWindowHandle
sourcepub fn new(native_window: NonNull<c_void>) -> Self
pub fn new(native_window: NonNull<c_void>) -> Self
Create a new handle to an OHNativeWindow
on OpenHarmony.
The handle will typically be created from an XComponent
, consult the
native XComponent
Guidelines for more details.
§Example
/// Called When the `XComponent` is created.
///
/// See the [XComponent Guidelines](https://gitee.com/openharmony/docs/blob/OpenHarmony-4.0-Release/en/application-dev/napi/xcomponent-guidelines.md)
/// for more details
extern "C" fn on_surface_created_callback(component: *mut OH_NativeXComponent, window: *mut c_void) {
let handle = OhosNdkWindowHandle::new(NonNull::new(window).unwrap());
}
