pub struct ScrollMetrics {
    pub total: usize,
    pub visible: usize,
    pub offset: usize,
}

Position of a scrolled view: how many rows exist, how many are visible and the first visible row.

Fields

total: usize

Rows of content.

visible: usize

Rows that fit.

offset: usize

pub fn max_offset(self) -> usize

The largest valid offset.

pub fn thumb(self, track: u16) -> (u16, u16)

Thumb start row and length inside a track of track rows.

pub fn offset_at(self, row: u16, track: u16) -> usize

The offset that puts the thumb under track row row (for clicks and drags).
