A structural change the consumer may choose to apply.

Variants

NodeMoved

A node finished being dragged to a new world position. from is its position at grab time. (to is also already written into GraphView; this lets the consumer react, e.g. record an undoable move.)

Fields

node: NodeId

from: WorldPos

to: WorldPos

StackMoved

A stack finished being dragged (by its header) to a new world position. from is its position at grab time; to is already written into GraphView.

Fields

stack: StackId

from: WorldPos

to: WorldPos

StackMemberMoved

A stack member was dragged to a new slot within its stack. The member at from_index should move so it ends up at to_index (i.e. remove at from_index, then insert at to_index).

Fields

stack: StackId

from_index: usize

to_index: usize

SelectionChanged

The selection set changed this frame.

LinkRequested

The user dragged a new link from an output to an input port.

Fields

from: PortAddr

to: PortAddr

LinkDeleteRequested

The user requested deletion of an existing link.

Fields

link: Link

NodesDeleteRequested

The user requested deletion of the given nodes (e.g. Delete key).

Fields

nodes: Vec<NodeId>

StacksDeleteRequested

The user requested deletion of the given stacks (e.g. Delete key while stacks are selected). The consumer decides what this means for its domain (e.g. emptying a fixed pipeline stage vs. removing the container).

Fields

stacks: Vec<StackId>

StackAddRequested

The user clicked the “Add” button at the bottom of a stack, requesting a new member be appended to that stack (e.g. via a group-specific menu).

Fields

stack: StackId

ContextMenu

The user requested a context menu at a world position (right-click on empty canvas).

Fields

at: WorldPos

LinkDropped

The user released an in-progress link drag over empty canvas. The consumer may offer to create a node and wire it to source: an output pin (when source_is_output) needing a consumer, or an input pin awaiting a producer.

Fields

source: PortAddr

source_is_output: bool

at: WorldPos
