Fields

dom_id: DomId

Unique identifier for the DOM

dynamic_css_overrides: BTreeMap<NodeId, FastHashMap<DomString, CssProperty>>

The style properties that should be overridden for this frame, cloned from the Css

tag_ids_to_hover_active_states: BTreeMap<TagId, (NodeId, HoverGroup)>

Stores all tags for nodes that need to activate on a :hover or :active event.

tab_index_tags: BTreeMap<TagId, (NodeId, TabIndex)>

Tags -> Focusable nodes

draggable_tags: BTreeMap<TagId, NodeId>

Tags -> Draggable nodes

tag_ids_to_node_ids: BTreeMap<TagId, NodeId>

Tag IDs -> Node IDs

node_ids_to_tag_ids: BTreeMap<NodeId, TagId>

Reverse of tag_ids_to_node_ids.

hover_callbacks: BTreeMap<NodeId, BTreeMap<HoverEventFilter, (Callback, RefAny)>>focus_callbacks: BTreeMap<NodeId, BTreeMap<FocusEventFilter, (Callback, RefAny)>>not_callbacks: BTreeMap<NodeId, BTreeMap<NotEventFilter, (Callback, RefAny)>>window_callbacks: BTreeMap<NodeId, BTreeMap<WindowEventFilter, (Callback, RefAny)>>

Implementations

impl UiState[src]

pub const fn get_dom(&self) -> &CompactDom[src]

impl UiState[src]

pub fn new(dom: Dom, parent_dom: Option<(DomId, NodeId)>) -> UiState[src]

The UiState contains all the tags (for hit-testing) as well as the mapping from Hit-testing tags to NodeIds (which are important for filtering input events and routing input events to the callbacks).

pub fn new_from_app_state<'a>(
    data: &RefAny,
    layout_info: LayoutInfo<'a>,
    parent_dom: Option<(DomId, NodeId)>,
    layout_callback: LayoutCallback
) -> UiState[src]

pub fn create_tags_for_hover_nodes(
    &mut self,
    hover_nodes: &BTreeMap<NodeId, HoverGroup>
)[src]

pub fn scan_for_iframe_callbacks(
    &self
) -> Vec<(NodeId, &(IFrameCallback, RefAny))>[src]

pub fn scan_for_gltexture_callbacks(
    &self
) -> Vec<(NodeId, &(GlCallback, RefAny))>[src]
