Struct DragTrack 

pub struct DragTrack {
    pub inset: f32,
    pub mirrored: bool,
}

Where a drag lands along a widget that takes one: see Widget::drag_track.

Fields

inset: f32

How far in from each end the travel starts, in logical pixels.

mirrored: bool

Whether the travel runs from the right in a right-to-left reading direction.

Implementations

impl DragTrack

pub const WHOLE: Self

The whole width, left to right: what a widget with no opinion answers.

pub fn fraction(self, rect: Rect, x: f32, rtl: bool) -> f32

Where x falls along rect’s travel, as a fraction 0..=1, for a reading direction that is right to left when rtl.

One function, used by a drag’s start, every move and its end alike: three copies of this arithmetic would agree on every slider until one of them did not.
