Struct TabsState 

pub struct TabsState {
    pub active: usize,
    pub offset: usize,
}

State for a Tabs widget.

Fields

active: usize

Active tab index.

offset: usize

Left-most tab index when overflow scrolling is active.

Implementations

impl TabsState

pub fn select(&mut self, index: usize, tab_count: usize) -> bool

Select a specific tab index.

pub fn next(&mut self, tab_count: usize) -> bool

Move active tab right by one.

pub fn previous(&mut self, tab_count: usize) -> bool

Move active tab left by one.

pub fn handle_key(&mut self, key: &KeyEvent, tab_count: usize) -> bool

Handle keyboard tab switching.

Supported:

• Left / Right
• number keys 1..9

pub fn handle_mouse( &mut self, event: &MouseEvent, hit: Option<(HitId, HitRegion, u64)>, expected_id: HitId, tab_count: usize, ) -> MouseResult

Handle mouse selection for tabs.

Hit data convention: each tab row registers data = tab_index as u64.

Trait Implementations

impl Clone for TabsState

fn clone(&self) -> TabsState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TabsState

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for TabsState

fn default() -> TabsState

Returns the “default value” for a type.

impl PartialEq for TabsState

fn eq(&self, other: &TabsState) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
