Result of calling callbacks, containing all state changes

Fields

should_scroll_render: bool

Whether the UI should be rendered due to a scroll event

callbacks_update_screen: Update

Whether the callbacks say to rebuild the UI or not

modified_window_state: Option<FullWindowState>

FullWindowState that was (potentially) modified in the callbacks

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

Text changes that don’t require full relayout

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

Image changes (for animated images/video)

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

Clip mask changes (for vector animations)

image_callbacks_changed: Option<BTreeMap<DomId, FastBTreeSet<NodeId>>>

Image callback changes (for OpenGL texture updates)

css_properties_changed: Option<BTreeMap<DomId, BTreeMap<NodeId, CssPropertyVec>>>

CSS property changes from callbacks

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

Scroll position changes from callbacks

update_focused_node: FocusUpdateRequest

Focus change request from callback (if any)

timers: Option<FastHashMap<TimerId, Timer>>

Timers added in callbacks

threads: Option<FastHashMap<ThreadId, Thread>>

Threads added in callbacks

timers_removed: Option<FastBTreeSet<TimerId>>

Timers removed in callbacks

threads_removed: Option<FastBTreeSet<ThreadId>>

Threads removed in callbacks

windows_created: Vec<WindowCreateOptions>

Windows created in callbacks

menus_to_open: Vec<(Menu, Option<LogicalPosition>)>

Menus to open (context menus or dropdowns)

tooltips_to_show: Vec<(AzString, LogicalPosition)>

Tooltips to show

hide_tooltip: bool

Whether to hide the currently displayed tooltip

cursor_changed: bool

Whether the cursor changed

stop_propagation: bool

Whether stopPropagation() was called (prevents bubbling up in DOM-style event propagation)

prevent_default: bool

Whether preventDefault() was called (prevents default browser behavior)

hit_test_update_requested: Option<LogicalPosition>

Hit test update requested at this position (for Debug API) When set, the shell layer should perform a hit test update before the next event dispatch

queued_window_states: Vec<FullWindowState>

Queued window states to apply in sequence (for simulating clicks, etc.) The shell layer should apply these one at a time, processing events after each.

text_input_triggered: Vec<(DomNodeId, Vec<EventFilter>)>

Text input events triggered by CreateTextInput These need to be processed by the recursive event loop to invoke user callbacks Format: Vec<(DomNodeId, Vec)>
