Struct CallbacksOfHitTest 

pub struct CallbacksOfHitTest {
    pub nodes_with_callbacks: BTreeMap<DomId, Vec<CallbackToCall>>,
}

Fields

nodes_with_callbacks: BTreeMap<DomId, Vec<CallbackToCall>>

A BTreeMap where each item is already filtered by the proper hit-testing type, meaning in order to get the proper callbacks, you simply have to iterate through all node IDs

Implementations

impl CallbacksOfHitTest

pub fn new( nodes_to_check: &NodesToCheck, events: &Events, layout_results: &[LayoutResult], ) -> Self

Determine which event / which callback(s) should be called and in which order

This function also updates / mutates the current window states focused_node as well as the window_state.previous_state

pub fn call( &mut self, previous_window_state: &Option<FullWindowState>, full_window_state: &FullWindowState, raw_window_handle: &RawWindowHandle, scroll_states: &BTreeMap<DomId, BTreeMap<NodeHierarchyItemId, ScrollPosition>>, gl_context: &OptionGlContextPtr, layout_results: &mut Vec<LayoutResult>, modifiable_scroll_states: &mut ScrollStates, image_cache: &mut ImageCache, system_fonts: &mut FcFontCache, system_callbacks: &ExternalSystemCallbacks, renderer_resources: &RendererResources, ) -> CallCallbacksResult

The actual function that calls the callbacks in their proper hierarchy and order
