Implementations§

Source§

impl EdgesCtx

Source

pub fn input(&self, ui: &Ui, node: NodeId, input: usize) -> Option<(Pos2, Vec2)>

Retrieves the position and normal of the specified input for the given node.

Returns None if either the node or input do not exist.

Source

pub fn output( &self, ui: &Ui, node: NodeId, output: usize, ) -> Option<(Pos2, Vec2)>

Retrieves the position and normal of the specified output for the given node.

Returns None if either the node or output do not exist.

Source

pub fn in_progress(&self, ui: &Ui) -> Option<EdgeInProgress>

If the user is in the progress of creating an edge, this returns the relevant info.

Source

pub fn graph_rect(&self) -> Rect

The full rect occuppied by the graph widget.
