Available on crate features unstable and views only.

User interface element and modifiers to re-configure it.

Required Methods

fn size(&self) -> Size

The intrinsic size of the View

fn draw(&self, bounds: Bounds, onto: &mut impl Output)

How the View is drawn

Provided Methods

fn event(&self, event: Event, offset: Point, bounds: Bounds)

User-interface Event handling of the View

fn padding(self, top: f32, right: f32, bottom: f32, left: f32) -> Padding<Self>

Add padding to all sides of the View

fn padding_top(self, pad: f32) -> Padding<Self>

Add padding to the top of the View

fn padding_right(self, pad: f32) -> Padding<Self>

Add padding to the right side of the View

fn padding_bottom(self, pad: f32) -> Padding<Self>

Add padding to the bottom of the View

fn padding_left(self, pad: f32) -> Padding<Self>

Add padding to the left side of the View

fn padding_horizontal(self, pad: f32) -> Padding<Self>

Add padding to the horizontal sides of the View

fn padding_vertical(self, pad: f32) -> Padding<Self>

Add padding to the vertical sides of the View

fn padding_both(self, horizontal: f32, vertical: f32) -> Padding<Self>

Add different padding to the horizontal and vertical sides of the View

fn padding_all(self, pad: f32) -> Padding<Self>

Add the same padding to all sides of the View

fn fixed(self, width: f32, height: f32) -> impl View

Set the size of the View to a fixed value.

fn width(self, width: f32) -> impl View

fn height(self, height: f32) -> impl View

fn across(self) -> impl View

Causes a tuple of Views to cascade horizontally, rather than vertically.

Note

For other views, nothing changes
