impl ScrollUnitsMix
where P: WidgetImpl,

pub fn h_wheel_unit(&self, unit: impl IntoVar<Length>)

P Horizontal offset added when the mouse wheel is scrolling by lines.

The unit value is multiplied by the MouseScrollDelta::LineDelta x value to determinate the scroll delta.

This property sets the HORIZONTAL_WHEEL_UNIT_VAR.

impl ScrollUnitsMix
where P: WidgetImpl,

pub fn v_wheel_unit(&self, unit: impl IntoVar<Length>)

P Vertical offset added when the mouse wheel is scrolling by lines.

The unit value is multiplied by the MouseScrollDelta::LineDelta y value to determinate the scroll delta.

This property sets the VERTICAL_WHEEL_UNIT_VAR`.

impl ScrollUnitsMix
where P: WidgetImpl,

pub fn wheel_units( &self, horizontal: impl IntoVar<Length>, vertical: impl IntoVar<Length>, )

P Horizontal and vertical offsets used when mouse wheel scrolling.

impl ScrollUnitsMix
where P: WidgetImpl,

pub fn zoom_wheel_unit(&self, unit: impl IntoVar<Factor>)

P Scale delta added when the mouse wheel is zooming by lines.

The unit value is multiplied by the MouseScrollDelta::LineDelta value to determinate the scale delta.

This property sets the ZOOM_WHEEL_UNIT_VAR.

impl ScrollUnitsMix
where P: WidgetImpl,

pub fn define_viewport_unit(&self, enabled: impl IntoVar<bool>)

P If the scroll defines its viewport size as the LayoutMetrics::viewport for the scroll content.

This property sets the DEFINE_VIEWPORT_UNIT_VAR.

Trait Implementations§

impl Deref for ScrollUnitsMix

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 into_any_rc(self: Rc<T>) -> Rc<dyn Any>
