Struct DraggableCanvas 

pub struct DraggableCanvas { /* private fields */ }

A canvas container that allows draggable elements within it.

Example

fn app() -> impl IntoElement {
    DraggableCanvas::new().child(Draggable::new().child("Draggable item"))
}

Implementations

impl DraggableCanvas

pub fn new() -> Self

Trait Implementations

impl ChildrenExt for DraggableCanvas

fn get_children(&mut self) -> &mut Vec<Element>

Returns a mutable reference to the internal children vector.

fn children(self, children: impl IntoIterator<Item = Element>) -> Self

Extends the children with an iterable of Elements.

fn maybe_child<C>(self, child: Option<C>) -> Self

where C: IntoElement,

Appends a child only when the Option is Some.

fn child<C>(self, child: C) -> Self

where C: IntoElement,

Appends a single child element.

impl Component for DraggableCanvas

fn render(&self) -> impl IntoElement

fn render_key(&self) -> DiffKey

impl ContainerExt for DraggableCanvas

fn padding(self, padding: impl Into<Gaps>) -> Self

Set the inner spacing between the element’s edges and its content. See Gaps.

fn min_width(self, minimum_width: impl Into<Size>) -> Self

Set the minimum width the element can shrink to. See Size.

fn min_height(self, minimum_height: impl Into<Size>) -> Self

Set the minimum height the element can shrink to. See Size.

fn max_width(self, maximum_width: impl Into<Size>) -> Self

Set the maximum width the element can grow to. See Size.

fn max_height(self, maximum_height: impl Into<Size>) -> Self

Set the maximum height the element can grow to. See Size.

fn visible_width(self, visible_width: impl Into<VisibleSize>) -> Self

Set how much of the measured width is actually used in layout. See VisibleSize.

fn visible_height(self, visible_height: impl Into<VisibleSize>) -> Self

Set how much of the measured height is actually used in layout. See VisibleSize.

impl Default for DraggableCanvas

fn default() -> Self

Returns the “default value” for a type.

impl KeyExt for DraggableCanvas

fn write_key(&mut self) -> &mut DiffKey

Returns a mutable reference to the element’s diff key.

fn key(self, key: impl Hash) -> Self

where Self: 'static,

Assign a key derived from any hashable value, used to reconcile elements in dynamic lists. The key is scoped to the element’s type, so the same value used on different element or component types never collides.

impl LayoutExt for DraggableCanvas

fn get_layout(&mut self) -> &mut LayoutData

Returns a mutable reference to the element’s layout data.

fn layout(self, layout: LayoutData) -> Self

Replace all of the element’s layout data at once. See LayoutData.

impl PartialEq for DraggableCanvas

fn eq(&self, other: &DraggableCanvas) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
