Struct KnobDef 

pub struct KnobDef {
    pub param_id: u32,
    pub label: &'static str,
    pub widget: Option<WidgetKind>,
    pub span: u32,
    pub param_id_y: Option<u32>,
    pub meter_ids: Option<Vec<u32>>,
}

A widget definition for the layout - either explicit type or auto-detected.

Fields

param_id: u32

label: &'static str

widget: Option<WidgetKind>

Explicit widget type override. None = auto-detect from param range.

span: u32

How many grid columns this widget spans. Default = 1.

param_id_y: Option<u32>

Second parameter ID for XY pad (Y axis). Ignored for other widgets.

meter_ids: Option<Vec<u32>>

Multiple meter IDs for multi-channel level meter. Ignored for other widgets.

Implementations

impl KnobDef

pub fn knob(param_id: impl Into<u32>, label: &'static str) -> Self

Knob (default for continuous params, auto-detected anyway).

pub fn slider(param_id: impl Into<u32>, label: &'static str) -> Self

Horizontal slider.

pub fn toggle(param_id: impl Into<u32>, label: &'static str) -> Self

Toggle button.

pub fn selector(param_id: impl Into<u32>, label: &'static str) -> Self

pub fn dropdown(param_id: impl Into<u32>, label: &'static str) -> Self

Dropdown list (click to open a popup showing all options).

pub fn meter(ids: &[u32], label: &'static str) -> Self

Level meter with one or more channels (display-only, reads from Plugin::get_meter()).

pub fn xy_pad( param_x: impl Into<u32>, param_y: impl Into<u32>, label: &'static str, ) -> Self

XY pad controlling two parameters.

pub fn with_span(self, span: u32) -> Self
