Expand description

The local state of a Scrollable.

Implementations

source

impl State

source

pub fn new() -> State

Creates a new State with the scrollbar located at the top.

source

pub fn scroll(
 &mut self,
 delta_y: f32,
 bounds: Rectangle<f32>,
 content_bounds: Rectangle<f32>
)

Apply a scrolling offset to the current State, given the bounds of the Scrollable and its contents.

source

pub fn scroll_to(
 &mut self,
 percentage: f32,
 bounds: Rectangle<f32>,
 content_bounds: Rectangle<f32>
)

Moves the scroll position to a relative amount, given the bounds of the Scrollable and its contents.

0 represents scrollbar at the top, while 1 represents scrollbar at the bottom.

source

pub fn offset(
 &self,
 bounds: Rectangle<f32>,
 content_bounds: Rectangle<f32>
) -> u32

Returns the current scrolling offset of the State, given the bounds of the Scrollable and its contents.

source

pub fn is_scroller_grabbed(&self) -> bool

Returns whether the scroller is currently grabbed or not.

source

pub fn is_scroll_box_touched(&self) -> bool

Returns whether the scroll box is currently touched or not.
