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,
impl<'a, Message, Theme, Renderer> Stack<'a, Message, Theme, Renderer>where
Renderer: Renderer,
sourcepub fn with_capacity(capacity: usize) -> Stack<'a, Message, Theme, Renderer>
pub fn with_capacity(capacity: usize) -> Stack<'a, Message, Theme, Renderer>
Creates a Stack
with the given capacity.
sourcepub fn with_children(
children: impl IntoIterator<Item = Element<'a, Message, Theme, Renderer>>,
) -> Stack<'a, Message, Theme, Renderer>
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.
sourcepub fn from_vec(
children: Vec<Element<'a, Message, Theme, Renderer>>,
) -> Stack<'a, Message, Theme, Renderer>
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.
sourcepub fn width(
self,
width: impl Into<Length>,
) -> Stack<'a, Message, Theme, Renderer>
pub fn width( self, width: impl Into<Length>, ) -> Stack<'a, Message, Theme, Renderer>
Sets the width of the Stack
.
sourcepub fn height(
self,
height: impl Into<Length>,
) -> Stack<'a, Message, Theme, Renderer>
pub fn height( self, height: impl Into<Length>, ) -> Stack<'a, Message, Theme, Renderer>
Sets the height of the Stack
.
sourcepub fn push(
self,
child: impl Into<Element<'a, Message, Theme, Renderer>>,
) -> Stack<'a, Message, Theme, Renderer>
pub fn push( self, child: impl Into<Element<'a, Message, Theme, Renderer>>, ) -> Stack<'a, Message, Theme, Renderer>
Adds an element to the Stack
.
