Struct gdnative_bindings_lily::graph_node::GraphNode

pub struct GraphNode { /* fields omitted */ }

core class GraphNode inherits Container (unsafe).

Official documentation

See the documentation of this class in the Godot engine’s official documentation. The method descriptions are generated from it and typically contain code samples in GDScript, not Rust.

Memory management

Non reference counted objects such as the ones of this type are usually owned by the engine.

GraphNode is a reference-only type. Persistent references can only exist in the unsafe Ref<GraphNode> form.

In the cases where Rust code owns an object of this type, for example if the object was just created on the Rust side and not passed to the engine yet, ownership should be either given to the engine or the object must be manually destroyed using Ref::free, or Ref::queue_free if it is a Node.

Class hierarchy

GraphNode inherits methods from:

• Container
• Control
• CanvasItem
• Node
• Object

Safety

All types in the Godot API have “interior mutability” in Rust parlance. To enforce that the official thread-safety guidelines are followed, the typestate pattern is used in the Ref and TRef smart pointers, and the Instance API. The typestate Access in these types tracks whether the access is unique, shared, or exclusive to the current thread. For more information, see the type-level documentation on Ref.

Implementations

impl GraphNode

Constants

pub const OVERLAY_BREAKPOINT: i64

pub const OVERLAY_DISABLED: i64

pub const OVERLAY_POSITION: i64

impl GraphNode

pub fn new() -> Ref<Self, Unique>

Creates a new instance of this object.

Because this type is not reference counted, the lifetime of the returned object is not automatically managed.

Immediately after creation, the object is owned by the caller, and can be passed to the engine (in which case the engine will be responsible for destroying the object) or destroyed manually using Ref::free, or preferably Ref::queue_free if it is a Node.

pub fn clear_all_slots(&self)

Disables all input and output slots of the GraphNode.

pub fn clear_slot(&self, idx: i64)

Disables input and output slot whose index is idx.

pub fn get_connection_input_color(&self, idx: i64) -> Color

Returns the color of the input connection idx.

pub fn get_connection_input_count(&self) -> i64

Returns the number of enabled input slots (connections) to the GraphNode.

pub fn get_connection_input_position(&self, idx: i64) -> Vector2

Returns the position of the input connection idx.

pub fn get_connection_input_type(&self, idx: i64) -> i64

Returns the type of the input connection idx.

pub fn get_connection_output_color(&self, idx: i64) -> Color

Returns the color of the output connection idx.

pub fn get_connection_output_count(&self) -> i64

Returns the number of enabled output slots (connections) of the GraphNode.

pub fn get_connection_output_position(&self, idx: i64) -> Vector2

Returns the position of the output connection idx.

pub fn get_connection_output_type(&self, idx: i64) -> i64

Returns the type of the output connection idx.

pub fn offset(&self) -> Vector2

The offset of the GraphNode, relative to the scroll offset of the GraphEdit. Note: You cannot use position directly, as GraphEdit is a Container.

pub fn overlay(&self) -> Overlay

Sets the overlay shown above the GraphNode. See [enum Overlay].

pub fn get_slot_color_left(&self, idx: i64) -> Color

Returns the color set to idx left (input) slot.

pub fn get_slot_color_right(&self, idx: i64) -> Color

Returns the color set to idx right (output) slot.

pub fn get_slot_type_left(&self, idx: i64) -> i64

Returns the (integer) type of left (input) idx slot.

pub fn get_slot_type_right(&self, idx: i64) -> i64

Returns the (integer) type of right (output) idx slot.

pub fn title(&self) -> GodotString

The text displayed in the GraphNode’s title bar.

pub fn is_close_button_visible(&self) -> bool

If true, the close button will be visible. Note: Pressing it will only emit the [signal close_request] signal, the GraphNode needs to be removed manually.

pub fn is_comment(&self) -> bool

If true, the GraphNode is a comment node.

pub fn is_resizable(&self) -> bool

If true, the user can resize the GraphNode. Note: Dragging the handle will only emit the [signal resize_request] signal, the GraphNode needs to be resized manually.

pub fn is_selected(&self) -> bool

If true, the GraphNode is selected.

pub fn is_slot_enabled_left(&self, idx: i64) -> bool

Returns true if left (input) slot idx is enabled, false otherwise.

pub fn is_slot_enabled_right(&self, idx: i64) -> bool

Returns true if right (output) slot idx is enabled, false otherwise.

pub fn set_comment(&self, comment: bool)

If true, the GraphNode is a comment node.

pub fn set_offset(&self, offset: Vector2)

The offset of the GraphNode, relative to the scroll offset of the GraphEdit. Note: You cannot use position directly, as GraphEdit is a Container.

pub fn set_overlay(&self, overlay: i64)

Sets the overlay shown above the GraphNode. See [enum Overlay].

pub fn set_resizable(&self, resizable: bool)

If true, the user can resize the GraphNode. Note: Dragging the handle will only emit the [signal resize_request] signal, the GraphNode needs to be resized manually.

pub fn set_selected(&self, selected: bool)

If true, the GraphNode is selected.

pub fn set_show_close_button(&self, show: bool)

If true, the close button will be visible. Note: Pressing it will only emit the [signal close_request] signal, the GraphNode needs to be removed manually.

pub fn set_slot(
    &self,
    idx: i64,
    enable_left: bool,
    type_left: i64,
    color_left: Color,
    enable_right: bool,
    type_right: i64,
    color_right: Color,
    custom_left: impl AsArg<Texture>,
    custom_right: impl AsArg<Texture>
)

Sets properties of the slot with ID idx. If enable_left/right, a port will appear and the slot will be able to be connected from this side. type_left/right is an arbitrary type of the port. Only ports with the same type values can be connected. color_left/right is the tint of the port’s icon on this side. custom_left/right is a custom texture for this side’s port. Note: This method only sets properties of the slot. To create the slot, add a Control-derived child to the GraphNode.

Default Arguments

• custom_left - null
• custom_right - null

pub fn set_title(&self, title: impl Into<GodotString>)

The text displayed in the GraphNode’s title bar.

Methods from Deref<Target = Container>

pub const NOTIFICATION_SORT_CHILDREN: i64

pub fn fit_child_in_rect(&self, child: impl AsArg<Control>, rect: Rect2)

Fit a child control in a given rect. This is mainly a helper for creating custom container classes.

pub fn queue_sort(&self)

Queue resort of the contained children. This is called automatically anyway, but can be called upon request.
