Struct zng :: scroll :: ScrollBarArgs Copy item path

impl ScrollBarArgs

pub fn new(orientation: Orientation) -> ScrollBarArgs

Arguments from scroll context.

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.

pub fn viewport_ratio(&self) -> ReadOnlyVar<Factor, ContextVar<Factor>>

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

See SCROLL for more details.

pub fn content_overflows(&self) -> Box<dyn VarBoxed<bool>>

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

See SCROLL for more details.

impl<T> Downcast for T
where T: Any,

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.
