Fields

should_scroll_render: bool

Whether the UI should be rendered anyways due to a (programmatic or user input) scroll event

callbacks_update_screen: Update

Whether the callbacks say to rebuild the UI or not

modified_window_state: Option<WindowState>

WindowState that was (potentially) modified in the callbacks

words_changed: Option<BTreeMap<DomId, BTreeMap<NodeId, AzString>>>

If a word changed (often times the case with text input), we don’t need to relayout / rerender the whole screen. The result is passed to the relayout() function, which will only change the single node that was modified

images_changed: Option<BTreeMap<DomId, BTreeMap<NodeId, (ImageRef, UpdateImageType)>>>

A callback can “exchange” and image for a new one without requiring a new display list to be rebuilt. This is important for animated images, especially video.

image_masks_changed: Option<BTreeMap<DomId, BTreeMap<NodeId, ImageMask>>>

Same as images, clip masks can be changed in callbacks, often the case with vector animations

css_properties_changed: Option<BTreeMap<DomId, BTreeMap<NodeId, Vec<CssProperty>>>>

If the focus target changes in the callbacks, the function will automatically restyle the DOM and set the new focus target

nodes_scrolled_in_callbacks: Option<BTreeMap<DomId, BTreeMap<NodeHierarchyItemId, LogicalPosition>>>

If the callbacks have scrolled any nodes, the new scroll position will be stored here

update_focused_node: Option<Option<DomNodeId>>

Whether the focused node was changed from the callbacks

timers: Option<FastHashMap<TimerId, Timer>>

Timers that were added in the callbacks

threads: Option<FastHashMap<ThreadId, Thread>>

Tasks that were added in the callbacks

timers_removed: Option<FastBTreeSet<TimerId>>

Timers that were added in the callbacks

threads_removed: Option<FastBTreeSet<ThreadId>>

Tasks that were added in the callbacks

windows_created: Vec<WindowCreateOptions>

Windows that were created in the callbacks

cursor_changed: bool

Whether the cursor changed in the callbacks
