Fields

graph: Graph<NodeData, DataType, ValueType>

node_order: Vec<NodeId>

Nodes are drawn in this order. Draw order is important because nodes that are drawn last are on top.

connection_in_progress: Option<(NodeId, AnyParameterId)>

An ongoing connection interaction: The mouse has dragged away from a port and the user is holding the click

selected_nodes: Vec<NodeId>

The currently selected node. Some interface actions depend on the currently selected node.

ongoing_box_selection: Option<Pos2>

The mouse drag start position for an ongoing box selection.

node_positions: SecondaryMap<NodeId, Pos2>

The position of each node.

node_orientations: SecondaryMap<NodeId, NodeOrientation>

Orientation of each node

node_finder: Option<NodeFinder<NodeTemplate>>

The node finder is used to create new nodes.

pan_zoom: PanZoom

The panning of the graph viewport.

_user_state: PhantomData<fn() -> UserState>

Implementations

impl<NodeData, DataType: PartialEq, ValueType, NodeKind, UserState> GraphEditorState<NodeData, DataType, ValueType, NodeKind, UserState>

pub fn new(default_zoom: f32) -> Self

impl<NodeData, DataType, ValueType, NodeTemplate, UserResponse, UserState, CategoryType> GraphEditorState<NodeData, DataType, ValueType, NodeTemplate, UserState>

where NodeData: NodeDataTrait<Response = UserResponse, UserState = UserState, DataType = DataType, ValueType = ValueType>, UserResponse: UserResponseTrait, ValueType: WidgetValueTrait<Response = UserResponse, UserState = UserState, NodeData = NodeData>, NodeTemplate: NodeTemplateTrait<NodeData = NodeData, DataType = DataType, ValueType = ValueType, UserState = UserState, CategoryType = CategoryType>, DataType: DataTypeTrait<UserState>, CategoryType: CategoryTrait,

pub fn draw_graph_editor( &mut self, ui: &mut Ui, all_kinds: impl NodeTemplateIter<Item = NodeTemplate>, user_state: &mut UserState, prepend_responses: Vec<NodeResponse<UserResponse, NodeData>>, ) -> GraphResponse<UserResponse, NodeData>

pub fn reset_zoom(&mut self, ui: &Ui)

Reset zoom to 1.0

pub fn zoom(&mut self, ui: &Ui, zoom_delta: f32)

Zoom within the where you call draw_graph_editor. Use values like 1.01, or 0.99 to zoom. For example: let zoom_delta = (scroll_delta * 0.002).exp();

Trait Implementations

impl<NodeData: Clone, DataType: Clone, ValueType: Clone, NodeTemplate: Clone, UserState: Clone> Clone for GraphEditorState<NodeData, DataType, ValueType, NodeTemplate, UserState>

fn clone( &self, ) -> GraphEditorState<NodeData, DataType, ValueType, NodeTemplate, UserState>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<NodeData, DataType: PartialEq, ValueType, NodeKind, UserState> Default for GraphEditorState<NodeData, DataType, ValueType, NodeKind, UserState>

fn default() -> Self

Returns the “default value” for a type.
