Struct NodeId

#[repr(C)]
pub struct NodeId { /* private fields */ }

Identifier for a Node.

IDs must be unique within the editor context. Generated using IdentifierGenerator::next_node.

Implementations

impl NodeId

pub fn set_draggable(&self, draggable: bool) -> &Self

Sets whether this node can be dragged by the user.

pub fn move_editor_to(&self) -> &Self

Pans the editor view to center on this node.

pub fn get_dimensions(&self) -> ImVec2

Gets the dimensions (width, height) of this node.

Note: This must be called after the node has been submitted in the current frame, otherwise the dimensions might be outdated or zero.

pub fn set_position( &self, x: f32, y: f32, coordinate_system: CoordinateSystem, ) -> &Self

Sets the position of the top-left corner of this node in the specified coordinate system.

pub fn get_position(&self, coordinate_system: CoordinateSystem) -> ImVec2

Gets the position of the top-left corner of this node in the specified coordinate system.

Note: This must be called after the node has been submitted in the current frame, otherwise the position might be outdated.

pub fn snap_to_grid(&self) -> &Self

Aligns the node’s top-left corner to the grid lines. Requires the StyleFlags::GridSnapping flag to be enabled in the style.

pub fn select(&self) -> &Self

Selects this node.

pub fn deselect(&self) -> &Self

Deselects this node. If no other nodes are selected, this is equivalent to EditorContext::clear_node_selection.

pub fn is_selected(&self) -> bool

Checks if this node is currently selected.

Trait Implementations

impl Clone for NodeId

fn clone(&self) -> NodeId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NodeId

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<NodeId> for i32

fn from(val: NodeId) -> Self

Converts to this type from the input type.

impl Hash for NodeId

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Hoverable for NodeId

fn is_hovered(&self, _scope: &OuterScope) -> bool

Checks if the node is hovered.

impl PartialEq for NodeId

fn eq(&self, other: &NodeId) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
