Implementations

impl HorNiceSlider

pub fn new<'a, T: Into<Option<&'a str>>>( x: i32, y: i32, width: i32, height: i32, title: T, ) -> HorNiceSlider

Creates a new widget, takes an x, y coordinates, as well as a width and height, plus a title

Arguments

• x - The x coordinate in the screen
• y - The y coordinate in the screen
• width - The width of the widget
• heigth - The height of the widget
• title - The title or label of the widget
