Struct ScrollRegion 

Source 
pub struct ScrollRegion {
    pub id: usize,
    pub x: f32,
    pub y: f32,
    pub width: f32,
    pub height: f32,
    pub content_width: f32,
    pub content_height: f32,
    pub max: Offset,
}
Expand description

A scrollable box. id is its index in tree order, stable across rebuilds as long as the tree’s shape is, which is what the shell keys offsets by.

Fields§

§id: usize§x: f32§y: f32§width: f32§height: f32§content_width: f32

The size of the content inside, which may exceed the box on either axis.

§content_height: f32§max: Offset

How far the content can travel on each axis: content - visible (>= 0).

Implementations§
