GraphElement

实验性： This class may be changed or removed in future versions.

继承： Container < Control < CanvasItem < Node < Object

派生： GraphFrame, 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.

信号

delete_request ( )

Emitted when removing the GraphElement is requested.

dragged ( from: Vector2, to: Vector2 )

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_end ( new_size: Vector2 )

Emitted when releasing the mouse button after dragging the resizer handle (see resizable).

resize_request ( new_size: Vector2 )

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

属性说明

bool draggable = true

  • void set_draggable ( value: bool )
  • bool is_draggable ( )

If true, the user can drag the GraphElement.

Vector2 position_offset = Vector2(0, 0)

  • void set_position_offset ( value: Vector2 )
  • Vector2 get_position_offset ( )

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

bool resizable = false

  • void set_resizable ( value: bool )
  • bool is_resizable ( )

If true, the user can resize the GraphElement.

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

bool selectable = true

  • void set_selectable ( value: bool )
  • bool is_selectable ( )

If true, the user can select the GraphElement.

bool selected = false

  • void set_selected ( value: bool )
  • bool is_selected ( )

If true, the GraphElement is selected.
