Implementations§

source§

impl ScrollBarArgs

source

pub fn new(orientation: Orientation) -> Self

Arguments from scroll context.

source

pub fn offset(&self) -> ContextVar<Factor>

Gets the context variable that gets and sets the offset for the orientation.

See SCROLL.vertical_offset and SCROLL.horizontal_offset for more details.

source

pub fn viewport_ratio(&self) -> ReadOnlyContextVar<Factor>

Gets the context variable that gets the viewport/content ratio for the orientation.

See SCROLL for more details.

source

pub fn content_overflows(&self) -> BoxedVar<bool>

Gets the context variable that gets if the scrollbar should be visible.

See SCROLL for more details.
