class_name Port
|
|
## A data type representing a port of a [DeckNode].
|
|
##
|
|
## Ports are used for connections between [DeckNode]s and can contain data that is passed between
|
|
## them on a node.
|
|
|
|
## The type index of this port.
|
|
var type: DeckType.Types
|
|
## The label of this port. Used by the renderer to display. How it's displayed depends on the renderer
|
|
## and the [member descriptor].
|
|
var label: String
|
|
## Hints to the renderer on how to display this port.[br]
|
|
## Can be either one of these: [code]button textfield spinbox slider textblock codeblock checkbox singlechoice multichoice[/code].[br]
|
|
## Additional descriptor properties can be specified after the type, delimited by a colon ([code]:[/code]).[br]
|
|
## @experimental
|
|
var descriptor: String
|
|
## A callback to get this port's value. Intended usage is by renderers that show an input field of some kind.
|
|
var value_callback: Callable

## The type of this port (input, output or virtual)
|
|
var port_type: DeckNode.PortType

## The local index of this port.
|

var index_of_type: int
|

## The global index of this port.

var index: int
|
|
|
|
## The value of this port.
