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.

Implementations§

source§

impl OhosNdkWindowHandle

source

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());
}
