Struct ScrollView 

Source 
pub struct ScrollView {
    pub top_visible: usize,
    pub visible_rows: usize,
    pub total: usize,
}
Expand description

How far a scrollable control has scrolled, in rows.

A second value getter beside PopupView, for the same reason: a scroll bar is host chrome the library merely knows about. It answers for a scrolling list box as well as for an open dropdown, which is why it is keyed by annotation rather than carried on the popup.

Fields§

§top_visible: usize

The first row showing.

§visible_rows: usize

How many rows the box can show at once.

§total: usize

How many rows there are altogether.

Implementations§

Source§

impl ScrollView

Source

pub fn is_scrollable(&self) -> bool

Whether a scroll bar would be drawn at all.

The bar is hidden whenever the plate is at least as tall as the content, which is exactly “every row fits”.
