Struct ScrollbarDrag 

pub struct ScrollbarDrag {
    pub entity: Entity,
    pub axis: ScrollbarAxisPick,
    pub grab: f32,
    pub start_offset: Vec2,
}

An in-flight thumb drag (pointer captured by the scrollbar).

Fields

entity: Entity

Scroll container whose bar is being dragged.

axis: ScrollbarAxisPick

Bar axis.

grab: f32

Pointer offset from the thumb’s leading edge at press time, in logical pixels along the bar axis. Keeps the grab point glued to the same spot on the thumb for the whole drag (absolute 1:1 mapping).

start_offset: Vec2

The container’s ScrollOffset when the drag began, so Escape can cancel the drag and restore the pre-drag scroll position (Qt drag-cancel contract).
