Struct cosmic::iced_widget::Stack

source ·
pub struct Stack<'a, Message, Theme = Theme, Renderer = Renderer> { /* private fields */ }
Expand description

A container that displays children on top of each other.

The first Element dictates the intrinsic Size of a Stack and will be displayed as the base layer. Every consecutive Element will be renderer on top; on its own layer.

Keep in mind that too much layering will normally produce bad UX as well as introduce certain rendering overhead. Use this widget sparingly!

Implementations§

source§

impl<'a, Message, Theme, Renderer> Stack<'a, Message, Theme, Renderer>
where Renderer: Renderer,

source

pub fn new() -> Stack<'a, Message, Theme, Renderer>

Creates an empty Stack.

source

pub fn with_capacity(capacity: usize) -> Stack<'a, Message, Theme, Renderer>

Creates a Stack with the given capacity.

source

pub fn with_children( children: impl IntoIterator<Item = Element<'a, Message, Theme, Renderer>>, ) -> Stack<'a, Message, Theme, Renderer>

Creates a Stack with the given elements.

source

pub fn from_vec( children: Vec<Element<'a, Message, Theme, Renderer>>, ) -> Stack<'a, Message, Theme, Renderer>

Creates a Stack from an already allocated Vec.

Keep in mind that the Stack will not inspect the Vec, which means it won’t automatically adapt to the sizing strategy of its contents.

If any of the children have a Length::Fill strategy, you will need to call Stack::width or Stack::height accordingly.

source

pub fn width( self, width: impl Into<Length>, ) -> Stack<'a, Message, Theme, Renderer>

Sets the width of the Stack.

source

pub fn height( self, height: impl Into<Length>, ) -> Stack<'a, Message, Theme, Renderer>

Sets the height of the Stack.

source

pub fn push( self, child: impl Into<Element<'a, Message, Theme, Renderer>>, ) -> Stack<'a, Message, Theme, Renderer>

Adds an element to the Stack.

source

pub fn push_maybe( self, child: Option<impl Into<Element<'a, Message, Theme, Renderer>>>, ) -> Stack<'a, Message, Theme, Renderer>

Adds an element to the Stack, if Some.

source

pub fn extend( self, children: impl IntoIterator<Item = Element<'a, Message, Theme, Renderer>>, ) -> Stack<'a, Message, Theme, Renderer>

Extends the Stack with the given children.
