Struct egui::widgets::DragValue

pub struct DragValue<'a> { /* fields omitted */ }

A numeric value that you can change by dragging the number. More compact than a Slider.

Implementations

impl<'a> DragValue<'a>

pub fn f32(value: &'a mut f32) -> Self

pub fn f64(value: &'a mut f64) -> Self

pub fn u8(value: &'a mut u8) -> Self

pub fn i32(value: &'a mut i32) -> Self

pub fn speed(self, speed: f32) -> Self

How much the value changes when dragged one point (logical pixel).

pub fn range(self, range: RangeInclusive<f32>) -> Self

Clamp the value to this range

pub fn prefix(self, prefix: impl ToString) -> Self

Show a prefix before the number, e.g. "x: "

pub fn suffix(self, suffix: impl ToString) -> Self

Add a suffix to the number, this can be e.g. a unit ("°" or " m")

pub fn min_decimals(self, min_decimals: usize) -> Self

Set a minimum number of decimals to display. Normally you don't need to pick a precision, as the slider will intelligently pick a precision for you. Regardless of precision the slider will use "smart aim" to help the user select nice, round values.

pub fn max_decimals(self, max_decimals: usize) -> Self

Set a maximum number of decimals to display. Values will also be rounded to this number of decimals. Normally you don't need to pick a precision, as the slider will intelligently pick a precision for you. Regardless of precision the slider will use "smart aim" to help the user select nice, round values.

pub fn fixed_decimals(self, num_decimals: usize) -> Self

Set an exact number of decimals to display. Values will also be rounded to this number of decimals. Normally you don't need to pick a precision, as the slider will intelligently pick a precision for you. Regardless of precision the slider will use "smart aim" to help the user select nice, round values.
