impl Default for Numeric

Source §

fn default() -> Self

Returns the “default value” for a type. Read more

Source §

impl HasWindowUID for Numeric

Source §

fn uid(&self) -> WindowUID

Must be static and unique for each object implementing Window. Generate once per instance using WindowUID::new.

Source §

fn set_width(&mut self, _: Size)

Unsupported

Source §

fn set_height(&mut self, _: Size)

Unsupported

Source §

fn set_width_constraint(&mut self, _: SizeConstraint)

Unsupported

Source §

fn set_height_constraint(&mut self, _: SizeConstraint)

Unsupported

Source §

fn set_visibility(&mut self, visibility: bool)

Source §

fn set_margin(&mut self, margin: Thickness)

Source §

fn set_border(&mut self, border: BorderStyle)

Source §

fn set_alignment( &mut self, horizontal: HorizontalAlignment, vertical: VerticalAlignment, )

Source §

fn set_enabled_state(&mut self, is_enabled: bool)

Changing the IsEnabled state usually changes the highlight color

Source §

impl Window for Numeric

Source §

fn render(&self, canvas: &mut Canvas)

Allows self to draw into its own Canvas The canvas size depends on other properties set and the terminal size itself It is guarenteed that the size of the Canvas is atleast 1x1

Source §

fn handle_event(&mut self, event: &mut WindowEvent)

The events are forwarded from crossterm with the only exception of Resize which will have the same dimensions as the resulting canvas If a event’s handled attributed is set to true it will stop bubbling otherwise it will keep bubbling until another Window marks it as handled Except for: Read more

Source §

fn is_enabled(&self) -> bool

Is self enabled? Indicated whether or not to handle input and if its focusable When false, Window is still eligible to receive events

Source §

fn children(&mut self, builder: SubWindowBuilder) -> SubWindows

Returns all children windows (and layouting Rects) Note: When changing the children make sure to also adjust the focus

Source §

fn focus(&self) -> Option<WindowRef>

Which child of the window has focus Is there is None, then ´self´ has focus

Source §

impl WindowLayout for Numeric

Source §

fn desired_size(&self, available_size: TPoint) -> TPoint

Parents call this to get the desired size of the child This must not exceed available_size on any axis When the result’s product is equal to 0, this window wont be drawn

Source §

fn border(&self) -> BorderStyle

Source §

fn alignment(&self) -> (HorizontalAlignment, VerticalAlignment)

Aligns self within its parent Window

Source §

fn is_visible(&self) -> bool

Source §

fn margin(&self) -> Thickness

Source §

fn desired_size_pre_hook(&mut self, available_size: TPoint)

This is similar to desired_size but will not return anything and can mutably change self This is executed before WindowLayout::desired_size Only implement if actually necessary
