pub struct ParamSlider<'a, P: Param> { /* private fields */ }
Expand description

A slider that integrates with NIH-plug’s Param types.

TODO: There are currently no styling options at all TODO: Handle scrolling for steps (and shift+scroll for smaller steps?)

Implementations§

source§

impl<'a, P: Param> ParamSlider<'a, P>

source

pub fn new(state: &'a mut State, param: &'a P) -> Self

Creates a new ParamSlider for the given parameter.

source

pub fn width(self, width: Length) -> Self

Sets the width of the ParamSlider.

source

pub fn height(self, height: Length) -> Self

Sets the height of the ParamSlider.

source

pub fn text_size(self, size: u16) -> Self

Sets the text size of the ParamSlider.

source

pub fn font(self, font: Font) -> Self

Sets the font of the ParamSlider.

source§

impl<'a, P: Param> ParamSlider<'a, P>

source

pub fn map<Message, F>(self, f: F) -> Element<'a, Message>where Message: 'static, F: Fn(ParamMessage) -> Message + 'static,

Convert this ParamSlider into an [Element] with the correct message. You should have a variant on your own message type that wraps around ParamMessage so you can forward those messages to IcedEditor::handle_param_message().
