egui_dock 0.19.0 - 2026/03/29

Added

• NodePath and TabPath structs, useful for more consistent and terse indexing of nodes and
  tabs. (#312)
• Indexing LeafNode with TabIndex. (#311)
• Indexing DockState using NodePath. (#312)
• New methods (#312):
  • DockState::node(_mut): returns a Node at a given NodePath,
  • DockState::leaf(_mut): returns a LeafNode at a given NodePath,
  • DockState::iter_surfaces(_mut)_indexed: returns a Surface iterator paired with its SurfaceIndex,
  • Surface::iter_nodes(_mut)_indexed: returns a Node<Tab> iterator paired with its NodeIndex,
  • Tree::leaf(_mut): returns a Result<&LeafNode<Tab>> at a given NodeIndex,
  • Node::iter_tabs(_mut)_indexed: returns a Tab iterator paried with its TabIndex.

Fixed

• No more panics when a window is shrunk to zero available space. (#309)
• No more panics while trying move a tab to the end of the list within the same leaf. (#308)

Breaking changes

• Upgraded to egui 0.34. (#314)
• Replaced all SurfaceIndex, NodeIndex, and TabIndex groupings with NodePath and TabPath in the argument lists
  of the following functions (#312):
  • DockState::set_active_tab,
  • DockState::set_focused_node_and_surface,
  • DockState::move_tab,
  • DockState::detach_tab,
  • DockState::remove_tab,
  • DockState::remove_leaf,
  • DockState::split,
  • DockState::focused_leaf,
  • TabViewer::context_menu,
  • TabViewer::on_add,
  • TabViewer::add_popup.
• Changed the return type of some methods (#312):
  • DockState::iter_all_nodes now returns impl Iterator<Item = (NodePath, &Node<Tab>)>,
  • DockState::iter_all_nodes_mut now returns impl Iterator<Item = (NodePath, &mut Node<Tab>)>,
  • DockState::iter_all_tabs now returns impl Iterator<Item = (TabPath, &Tab)>,
  • DockState::iter_all_tabs_mut now returns impl Iterator<Item = (TabPath, &mut Tab)>,
  • DockState::iter_leaves now returns impl Iterator<Item = (NodePath, &LeafNode<Tab>)>,
  • DockState::iter_leaves_mut now returns impl Iterator<Item = (NodePath, &mut LeafNode<Tab>)>,
  • DockState::find_tab_from now returns Option<TabPath>,
  • DockState::find_tab now returns Option<TabPath>,
  • Surface::iter_all_tabs now returns impl Iterator<Item = ((NodeIndex, TabIndex), &Tab)>,
  • Surface::iter_all_tabs_mut now returns impl Iterator<Item = ((NodeIndex, TabIndex), &mut Tab)>,
  • Tree::set_active_tab now returns Result<()> (Err if any of the indices are invalid),
  • LeafNode::::set_active_tab now returns Result<()> (Err if the tab index is invalid).
• impl From<(SurfaceIndex, NodeIndex, TabInsert)> for TabDestination was replaced with
  impl From<(NodePath, TabInsert)> for TabDestination. (#312)

Deprecated

• DockArea::show - use DockArea::show_inside instead. (#314)
