Fields

document_id: DocumentId

A "document" in WebRender usually corresponds to one tab (i.e. in Azuls case, the whole window).

pipeline_id: PipelineId

One "document" (tab) can have multiple "pipelines" (important for hit-testing).

A document can have multiple pipelines, for example in Firefox the tab / navigation bar, the actual browser window and the inspector are seperate pipelines, but contained in one document. In Azul, one pipeline = one document (this could be improved later on).

epoch: Epoch

The "epoch" is a frame counter, to remove outdated images, fonts and OpenGL textures when they're not in use anymore.

cached_display_list: CachedDisplayList

Current display list active in this window (useful for debugging)

layout_result: SolvedLayoutCache

Currently active, layouted rectangles

gl_texture_cache: GlTextureCache

Currently GL textures inside the active CachedDisplayList

scrolled_nodes: BTreeMap<DomId, ScrolledNodes>

Current scroll states of nodes (x and y position of where they are scrolled)

scroll_states: ScrollStates

States of scrolling animations, updated every frame

Implementations

impl WindowInternal[src]

pub fn get_current_scroll_states(
    &self,
    ui_states: &BTreeMap<DomId, UiState>
) -> BTreeMap<DomId, BTreeMap<NodeId, ScrollPosition>>[src]

Returns a copy of the current scroll states + scroll positions
