Enum CompositionHostEvent 

pub enum CompositionHostEvent {
    Ready {
        compositor: IUnknown,
        width: f64,
        height: f64,
        scale: f64,
    },
    Metrics {
        width: f64,
        height: f64,
        scale: f64,
    },
}

Layout and compositor events from a composition host.

Width and height are in device-independent pixels (DIPs). Scale converts DIPs to pixels.

Variants

Ready

Provides the application-safe compositor capability for a newly bound host.

Fields
