A toggle button

Implementations

impl ToggleButton

pub fn new(state: impl Fn() -> bool + 'static) -> Self

pub fn new_rw( state: impl SignalGet<bool> + SignalUpdate<bool> + Copy + 'static, ) -> Self

pub fn on_toggle(self, ontoggle: impl Fn(bool) + 'static) -> Self

Add an event handler to be run when the button is toggled.

This does not run if the state is changed because of an outside signal. This handler is only called if this button is clicked or switched

pub fn toggle_style( self, style: impl Fn(ToggleButtonCustomStyle) -> ToggleButtonCustomStyle + 'static, ) -> Self

Trait Implementations

impl View for ToggleButton

fn id(&self) -> ViewId

fn debug_name(&self) -> Cow<'static, str>

fn update(&mut self, _cx: &mut UpdateCx<'_>, state: Box<dyn Any>)

Use this method to react to changes in view-related state. You will usually send state to this hook manually using the View’s Id handle

fn event_before_children( &mut self, cx: &mut EventCx<'_>, event: &Event, ) -> EventPropagation

fn compute_layout(&mut self, _cx: &mut ComputeLayoutCx<'_>) -> Option<Rect>

Responsible for computing the layout of the view’s children.

fn style_pass(&mut self, cx: &mut StyleCx<'_>)

Use this method to style the view’s children.

fn paint(&mut self, cx: &mut PaintCx<'_>)

View-specific implementation. Will be called in PaintCx::paint_view. Usually you’ll call paint_view for every child view. But you might also draw text, adjust the offset, clip or draw text.

fn view_style(&self) -> Option<Style>

fn view_class(&self) -> Option<StyleClassRef>

fn layout(&mut self, cx: &mut LayoutCx<'_>) -> NodeId

Use this method to layout the view’s children. Usually you’ll do this by calling LayoutCx::layout_node.

fn event_after_children( &mut self, cx: &mut EventCx<'_>, event: &Event, ) -> EventPropagation

fn scroll_to( &mut self, cx: &mut AppState, target: ViewId, rect: Option<Rect>, ) -> bool

Scrolls the view and all direct and indirect children to bring the target view to be visible. Returns true if this view contains or is the target.
