Struct FFTController 

Source 
pub struct FFTController { /* private fields */ }
Expand description

Controller to get/set FFT panel visibility/size and subscribe to updates.

Implementations§

Source§

impl FFTController

Source

pub fn new() -> Self

Create a fresh controller.

Source

pub fn is_shown(&self) -> bool

Query whether the FFT panel is (last known) shown.

Source

pub fn set_shown(&self, show: bool)

Request that the FFT panel be shown/hidden. This records the request and notifies subscribers; whether the runtime honors it depends on the UI.

Source

pub fn get_current_size(&self) -> Option<[f32; 2]>

Get last observed panel size in physical pixels (if known).

Source

pub fn request_set_size(&self, size_px: [f32; 2])

Request a panel size change (physical pixels). Recorded and will be exposed to the UI which may choose to honor it.

Source

pub fn subscribe(&self) -> Receiver<FFTPanelInfo>

Subscribe to FFT panel updates. Returned receiver receives FFTPanelInfo whenever the UI publishes it.

Source

pub fn get_last_info(&self) -> Option<FFTPanelInfo>

Get the last published FFT panel info, if any.
