Enum FlatlandDisplayRequest

pub enum FlatlandDisplayRequest {
    SetContent {
        token: ViewportCreationToken,
        child_view_watcher: ServerEnd<ChildViewWatcherMarker>,
        control_handle: FlatlandDisplayControlHandle,
    },
    SetDevicePixelRatio {
        device_pixel_ratio: VecF,
        control_handle: FlatlandDisplayControlHandle,
    },
}

This API connects to the singleton “primary display”, and allows a tree of Flatland content to be attached underneath. Only one FlatlandDisplay client connection is allowed at one time.

Variants

SetContent

Fields

token: ViewportCreationToken

child_view_watcher: ServerEnd<ChildViewWatcherMarker>

control_handle: FlatlandDisplayControlHandle

SetDevicePixelRatio

Sets the ratio of display’s physical pixels to device independent pixels that should be used for the tree of Flatland content that are attached to this display. See [LayoutInfo.device_pixel_ratio] for details.

The default value is (1.0, 1.0). The valid values are 1.0 and above.

Fields

device_pixel_ratio: VecF

control_handle: FlatlandDisplayControlHandle
