Struct BrowserTabs 

pub struct BrowserTabs { /* private fields */ }

A horizontal strip of browser-style closable tabs.

See the module-level docs for an example.

Implementations

impl BrowserTabs

pub fn new(id_salt: impl Hash) -> Self

Create an empty strip. id_salt scopes the widget’s interaction state in egui memory; two BrowserTabs strips on the same page need distinct salts.

pub fn with_tab(self, tab: BrowserTab) -> Self

Push a tab at construction time (builder form).

pub fn show_new_button(self, show: bool) -> Self

Whether to show the trailing “+” button. Default: true.

pub fn min_tab_width(self, w: f32) -> Self

Minimum width for a single tab in points. Default: 120.0.

pub fn max_tab_width(self, w: f32) -> Self

Maximum width for a single tab in points. Default: 220.0.

pub fn add_tab(&mut self, tab: BrowserTab)

Append a tab. If no tab is currently selected, the new tab becomes the active one. Subsequent calls don’t change the active tab unless the caller invokes Self::set_selected.

pub fn remove_tab(&mut self, id: &str) -> bool

Remove a tab by id. If the removed tab was active, selection moves to the next tab (or the previous one if it was the last). Returns true if a tab was actually removed.

pub fn selected(&self) -> Option<&str>

Currently active tab id, if any.

pub fn set_selected(&mut self, id: impl Into<String>)

Set the active tab. No-op if no tab with that id exists.

pub fn tabs(&self) -> &[BrowserTab]

Borrow the underlying tab list.

pub fn tab(&self, id: &str) -> Option<&BrowserTab>

Find a tab by id.

pub fn tab_mut(&mut self, id: &str) -> Option<&mut BrowserTab>

Find a tab by id (mutably) so the caller can flip dirty or rename it.

pub fn take_events(&mut self) -> Vec<BrowserTabsEvent>

Drain events queued since the last call. Returns events in the order they were emitted.

pub fn show(&mut self, ui: &mut Ui) -> Response

Render the strip. Call once per frame.
