Struct Selection 

pub struct Selection<'a> { /* private fields */ }

A selection of surfaces matching a selector

Provides methods to interact with all matching surfaces at once. Created via Shell::select().

Implementations

impl<'a> Selection<'a>

pub fn on_callback<F, R>( &mut self, callback_name: &str, handler: F, ) -> &mut Selection<'a>

where F: Fn(CallbackContext) -> R + Clone + 'static, R: IntoValue,

Registers a callback handler for all matching surfaces

Handler receives a CallbackContext with surface identity and shell control.

pub fn on_callback_with_args<F, R>( &mut self, callback_name: &str, handler: F, ) -> &mut Selection<'a>

where F: Fn(&[Value], CallbackContext) -> R + Clone + 'static, R: IntoValue,

Registers a callback handler that receives arguments for all matching surfaces

pub fn with_component<F>(&self, f: F)

where F: FnMut(&ComponentInstance),

Executes a function with each matching component instance

pub fn set_property(&self, name: &str, value: &Value) -> Result<(), Error>

Sets a property value on all matching surfaces

pub fn get_property(&self, name: &str) -> Result<Vec<Value>, Error>

Gets property values from all matching surfaces

pub fn configure<F>(&self, f: F)

where F: FnMut(&ComponentInstance, LayerSurfaceHandle<'_>),

Executes a configuration function with component and surface handle for matching surfaces

pub fn count(&self) -> usize

Returns the number of surfaces matching the selector

pub fn is_empty(&self) -> bool

Checks if no surfaces match the selector

pub fn info(&self) -> Vec<SurfaceInfo>

Returns information about all matching surfaces
