Struct iced_pure::widget::scrollable::Scrollable

pub struct Scrollable<'a, Message, Renderer> { /* private fields */ }

A widget that can vertically display an infinite amount of content with a scrollbar.

Implementations

impl<'a, Message, Renderer: Renderer> Scrollable<'a, Message, Renderer>

pub fn new(content: impl Into<Element<'a, Message, Renderer>>) -> Self

Creates a new Scrollable.

pub fn height(self, height: Length) -> Self

Sets the height of the Scrollable.

pub fn scrollbar_width(self, scrollbar_width: u16) -> Self

Sets the scrollbar width of the Scrollable . Silently enforces a minimum value of 1.

pub fn scrollbar_margin(self, scrollbar_margin: u16) -> Self

Sets the scrollbar margin of the Scrollable .

pub fn scroller_width(self, scroller_width: u16) -> Self

Sets the scroller width of the Scrollable .

It silently enforces a minimum value of 1.

pub fn on_scroll(self, f: impl Fn(f32) -> Message + 'a) -> Self

Sets a function to call when the Scrollable is scrolled.

The function takes the new relative offset of the Scrollable (e.g. 0 means top, while 1 means bottom).

pub fn style(self, style_sheet: impl Into<Box<dyn StyleSheet + 'a>>) -> Self

Sets the style of the Scrollable .

    tree: &'b mut Tree,
    layout: Layout<'_>,
    renderer: &Renderer
) -> Option<Element<'b, Message, Renderer>>

Returns the overlay of the Widget, if there is any.
