Struct ScrollRegion 

pub struct ScrollRegion {
    pub key: Key,
    pub rect: Rect,
    pub clip: Rect,
    pub inert: bool,
    pub handler: bool,
    /* private fields */
}

A scroll container’s on-screen area, for wheel routing — or an on_scroll node’s, which takes the wheel the same way and turns it into an event instead of an offset.

Fields

key: Key

rect: Rect

clip: Rect

inert: bool

Outside the frame’s modal scope: the bar still draws, the wheel and the thumb do nothing.

handler: bool

The node declared on_scroll: the wheel over it is an event on it, no bars are drawn and no offset is kept. A region that is both — a scroller that also declared the row — is the handler’s: the app asked to hear the wheel, and hearing it and having the content move under it would be two answers to one notch.
