Struct DockingContext 

pub struct DockingContext { /* private fields */ }

Registry of DockTabs containers for efficient lookup during drag operations.

Caches the locations and metadata of all DockTabs widgets in the tree so that cross-container drop target detection does not need a full tree traversal on every mouse move.

Implementations

impl DockingContext

pub fn new() -> Self

Create a new empty docking context.

pub fn style(&self) -> &DockingStyle

Get a reference to the docking style.

pub fn style_mut(&mut self) -> &mut DockingStyle

Get a mutable reference to the docking style.

pub fn set_style(&mut self, style: DockingStyle)

Replace the docking style.

pub fn invalidate(&mut self)

Mark the cache as needing a rebuild.

Call this after any tree structure change (node add/remove, tab transfer, split).

pub fn rebuild_cache(&mut self, tree: &UiTree)

Rebuild the container cache from the tree.

Walks the tree to find all DockTabs widgets and caches their layout and tab count.

pub fn find_tab_containers( &mut self, tree: &UiTree, ) -> &HashMap<NodeId, CachedContainerInfo>

Get the cached tab containers, rebuilding if necessary.

pub fn is_dirty(&self) -> bool

Check if the cache is dirty and needs a rebuild.

pub fn container_count(&self) -> usize

Get the number of cached containers.

impl Default for DockingContext

fn default() -> Self
