Implementations

impl ActiveWindowName

pub fn new( max_chars: usize, style: TextStyle, is_greedy: bool, right_justified: bool, ) -> Self

Create a new ActiveWindowName widget with a maximum character count.

max_chars can not be lower than 3.

Trait Implementations

impl Clone for ActiveWindowName

fn clone(&self) -> ActiveWindowName

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ActiveWindowName

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

Formats the value using the given formatter.

impl PartialEq for ActiveWindowName

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl<X: XConn> Widget<X> for ActiveWindowName

fn draw( &mut self, ctx: &mut Context<'_>, s: usize, f: bool, w: u32, h: u32, ) -> Result<()>

Render the current state of the widget to the status bar window.

fn current_extent( &mut self, ctx: &mut Context<'_>, h: u32, ) -> Result<(u32, u32)>

Current required width and height for this widget due to its content

fn is_greedy(&self) -> bool

If true, this widget will expand to fill remaining available space after layout has been computed. If multiple greedy widgets are present in a given StatusBar then the available space will be split evenly between all widgets.

fn require_draw(&self) -> bool

Does this widget currently require re-rendering? (should be reset to false when ‘draw’ is called)

fn on_refresh(&mut self, state: &mut State<X>, x: &X) -> Result<()>

A refresh hook to be run in order to update this Widget

fn on_event( &mut self, event: &XEvent, state: &mut State<X>, x: &X, ) -> Result<()>

An event hook to be run in order to update this Widget

fn update_schedule(&mut self) -> Option<UpdateSchedule>

An UpdateSchedule to allow for external updates to this Widget’s state independently of the window manager event loop.

fn on_startup(&mut self, state: &mut State<X>, x: &X) -> Result<()>

A startup hook to be run in order to initialise this Widget

fn on_new_client(&mut self, id: Xid, state: &mut State<X>, x: &X) -> Result<()>

A manage hook to be run in order to update this Widget
