Struct DocumentEmbedderControls 

pub(crate) struct DocumentEmbedderControls {
    window: Dom<Window>,
    user_interface_element_index: Cell<Epoch>,
    visible_elements: DomRefCell<FxHashMap<NoTrace<Epoch>, ControlElement>>,
}

Fields

window: Dom<Window>

The Window element for this [DocumentUserInterfaceElements].

user_interface_element_index: Cell<Epoch>

The id of the next user interface element that the Document requests that the embedder show. This is used to track user interface elements in the API.

visible_elements: DomRefCell<FxHashMap<NoTrace<Epoch>, ControlElement>>

A map of visible user interface elements.

Implementations

impl DocumentEmbedderControls

pub fn new(window: &Window) -> Self

pub(crate) fn next_control_id(&self) -> EmbedderControlId

Generate the next unused EmbedderControlId. This method is only needed for some older types of controls that are still being migrated, and it will eventually be removed.

pub(crate) fn show_embedder_control( &self, element: ControlElement, request: EmbedderControlRequest, ) -> EmbedderControlId

pub(crate) fn hide_embedder_control(&self, element: &Element)

pub(crate) fn handle_embedder_control_response( &self, id: EmbedderControlId, response: EmbedderControlResponse, can_gc: CanGc, )

Trait Implementations

impl MallocSizeOf for DocumentEmbedderControls

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.

impl Traceable for DocumentEmbedderControls

unsafe fn trace(&self, tracer: *mut JSTracer)

Trace self.
