GraphElement¶

Inherits: Container < Control < CanvasItem < Node < Object

Inherited By: GraphNode

A container that represents a basic element that can be placed inside a GraphEdit control.

描述¶

GraphElement allows to create custom elements for a GraphEdit graph. By default such elements can be selected, resized, and repositioned, but they cannot be connected. For a graph element that allows for connections see GraphNode.

属性¶

bool	draggable	`true`
Vector2	position_offset	`Vector2(0, 0)`
bool	resizable	`false`
bool	selectable	`true`
bool	selected	`false`

信号¶

close_request ( )

Emitted when closing the GraphElement is requested.

dragged ( Vector2 from, Vector2 to )

Emitted when the GraphElement is dragged.

node_deselected ( )

Emitted when the GraphElement is deselected.

node_selected ( )

Emitted when the GraphElement is selected.

position_offset_changed ( )

Emitted when the GraphElement is moved.

raise_request ( )

Emitted when displaying the GraphElement over other ones is requested. Happens on focusing (clicking into) the GraphElement.

resize_request ( Vector2 new_minsize )

Emitted when resizing the GraphElement is requested. Happens on dragging the resizer handle (see resizable).

Property Descriptions¶

bool draggable = true

void set_draggable ( bool value )
bool is_draggable ( )

If true, the user can drag the GraphElement.

Vector2 position_offset = Vector2(0, 0)

void set_position_offset ( Vector2 value )
Vector2 get_position_offset ( )

The offset of the GraphElement, relative to the scroll offset of the GraphEdit.

bool resizable = false

void set_resizable ( bool value )
bool is_resizable ( )

If true, the user can resize the GraphElement.

Note: Dragging the handle will only emit the resize_request signal, the GraphElement needs to be resized manually.

bool selectable = true

void set_selectable ( bool value )
bool is_selectable ( )

If true, the user can select the GraphElement.

bool selected = false

void set_selected ( bool value )
bool is_selected ( )

If true, the GraphElement is selected.
