Struct NodeConstructor

pub struct NodeConstructor<'a> { /* private fields */ }

Used to construct a node and stores the relevant ui code for its title and attributes This is used so that the nodes can be rendered in the context depth order

Implementations

impl<'a, 'b> NodeConstructor<'a>

pub fn new(id: usize, args: NodeArgs) -> Self

Create a new node to be displayed in a Context. id should be the same accross frames and should not be the same as any other currently used nodes

pub fn with_title(self, title: impl FnOnce(&mut Ui) -> Response + 'a) -> Self

Add a title to a node

pub fn with_input_attribute( self, id: usize, args: PinArgs, attribute: impl FnOnce(&mut Ui) -> Response + 'a, ) -> Self

Add an input attibute to a node, this attribute can be connected to output attributes of other nodes id should be the same accross frames and should not be the same as any other currently used attributes the attribute should return a egui::Response to be checked for interaction

pub fn with_output_attribute( self, id: usize, args: PinArgs, attribute: impl FnOnce(&mut Ui) -> Response + 'a, ) -> Self

Add an output attibute to a node, this attribute can be connected to input attributes of other nodes id should be the same accross frames and should not be the same as any other currently used attributes the attribute should return a egui::Response to be checked for interaction

pub fn with_static_attribute( self, id: usize, attribute: impl FnOnce(&mut Ui) -> Response + 'a, ) -> Self

Add a static attibute to a node, this attribute can’t be connected to any other attributes id should be the same accross frames and should not be the same as any other currently used attributes the attribute should return a egui::Response to be checked for interaction

pub fn with_origin(self, origin: Pos2) -> Self

Set the position of the node in screen space when it is first created. To modify it after creation use one of the set_node_pos methods of the Context

pub fn id(&self) -> usize

Get the id of this NodeConstructor
