Struct TabGroupContext 

pub struct TabGroupContext { /* private fields */ }

What a skin needs to draw a tab group, and the callbacks it invokes rather than reimplementing behavior.

Implementations

impl TabGroupContext

pub fn node(&self) -> NodeId

The Tabs node this group mirrors, for a skin that needs to name the group in a drag payload or a drop target.

pub fn panels(&self) -> &[Arc<dyn PanelView>]

Every panel in the group, in tab order — visible or not. A skin filters with PanelView::visible when it draws.

pub fn active_ix(&self) -> usize

pub fn active_panel(&self) -> Option<&Arc<dyn PanelView>>

The panel on screen, which is the displayed tab unless that panel has gone invisible.

pub fn drop_indicator(&self) -> Option<DropIndicator>

pub fn is_zoomed(&self) -> bool

pub fn is_collapsed(&self) -> bool

pub fn is_closable(&self) -> bool

Whether closing the displayed panel is allowed at all, so a skin knows whether to offer a Close control.

pub fn is_locked(&self) -> bool

pub fn is_draggable(&self) -> bool

pub fn is_droppable(&self) -> bool

pub fn select_tab(&self, ix: usize, window: &mut Window, cx: &mut App)

pub fn close(&self, panel: PanelId, window: &mut Window, cx: &mut App)

pub fn toggle_zoom(&self, window: &mut Window, cx: &mut App)

pub fn drag_panel(&self, ix: usize, cx: &App) -> Option<DragPanel>

The drag payload for the tab at ix, for a skin wiring on_drag onto its tabs. None when ix names no panel.

pub fn drop_panel( &self, drag: DragPanel, ix: Option<usize>, activate: bool, window: &mut Window, cx: &mut App, )

A panel dropped on the tab bar. ix names the slot it lands in, or None to append; activate decides whether it becomes displayed.

pub fn drop_item( &self, item: AnyDrag, placement: Option<Placement>, window: &mut Window, cx: &mut App, )

A host-owned drag dropped on the tab bar. placement is None to merge into this group rather than split beside it.

Trait Implementations

impl Clone for TabGroupContext

fn clone(&self) -> TabGroupContext

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
