Struct XComponent 

pub struct XComponent(/* private fields */);

Accept XComponent with env and exports

Example

#[module_exports]
pub fn init(exports: Object, env: Env) -> Result<()> {
    let xcomponent = XComponent::init(env, exports)?;

    Ok(())
}

Implementations

impl XComponent

pub fn init(env: Env, exports: Object<'_>) -> Result<Self>

pub fn id(&self) -> Result<String>

Get current xcomponent instance’s id

pub fn raw(&self) -> *mut OH_NativeXComponent

get raw point

pub fn set_frame_rate(&self, min: i32, max: i32, expected: i32) -> Result<()>

pub fn register_callback(&self) -> Result<()>

Register callbacks
For multi-mode, it will use hashmap to store all of your callbacks closure.
This may cause xcomponent being slower, if you want to avoid this.
You can disable feature with callbacks and use register_native_callback

pub unsafe fn register_native_callback( &self, callbacks: Box<OH_NativeXComponent_Callback>, ) -> Result<()>

Use ffi to register callbacks directly.

pub fn size(&self, window: WindowRaw) -> Result<XComponentSize>

Get current XComponent’s size info include width and height.

pub fn offset(&self, window: WindowRaw) -> Result<XComponentOffset>

Get the offset of the surface held by the current XComponent.

pub fn on_frame_callback( &self, cb: fn(XComponentRaw, u64, u64) -> Result<()>, ) -> Result<()>

pub fn on_surface_changed(&self, cb: fn(XComponentRaw, WindowRaw) -> Result<()>)

pub fn on_surface_created(&self, cb: fn(XComponentRaw, WindowRaw) -> Result<()>)

pub fn on_surface_destroyed( &self, cb: fn(XComponentRaw, WindowRaw) -> Result<()>, )

pub fn on_touch_event( &self, cb: fn(XComponentRaw, WindowRaw, TouchEventData) -> Result<()>, )
