Struct nannou::ui::widget::graph::NodeWidget

pub struct NodeWidget<'a, NI, W> where
    NI: 'a + NodeId,  { /* fields omitted */ }

Returned when a NodeContext is assigned a widget.

This intermediary type allows for accessing the widget::Id before the widget itself is instantiated.

Methods

impl<'a, NI, W> NodeWidget<'a, NI, W> where     NI: NodeId,     W: 'static + Widget,

pub fn widget_id(&self, ui: &mut UiCell) -> NodeIndex<u32>

Retrieve the widget::Id that will be used to instantiate this node's widget.

pub fn map<M>(self, map: M) -> NodeWidget<'a, NI, W> where     M: FnOnce(W) -> W,

Map over the inner widget.

pub fn set(self, ui: &mut UiCell) -> <W as Widget>::Event

Set the given widget for the node at node_id().

Methods from Deref<Target = NodeContext<'a, NI>>

pub fn node_id(&self) -> NI

The unique identifier associated with this node.

pub fn point(&self) -> [f64; 2]

The location of the node.

Trait Implementations

impl<'a, NI, W> Deref for NodeWidget<'a, NI, W> where     NI: NodeId,

type Target = NodeContext<'a, NI>

The resulting type after dereferencing.

fn deref(&self) -> &<NodeWidget<'a, NI, W> as Deref>::Target

Dereferences the value.
