WidgetToString

Documentation

• Class name: WidgetToString
• Category: KJNodes/text
• Output node: False

This node is designed to extract and return the value of a specified widget from a given node within a workflow. It focuses on retrieving widget values as strings, optionally aggregating all widget values from the specified node if required.

Input types

Required

• id
  • Specifies the unique identifier of the node from which to extract the widget value, playing a crucial role in identifying the correct node within a workflow.
  • Comfy dtype: INT
  • Python dtype: int
• widget_name
  • The name of the widget whose value is to be retrieved, determining which specific widget's value is extracted from the node.
  • Comfy dtype: STRING
  • Python dtype: str
• return_all
  • A boolean flag that, when set to true, changes the node's behavior to return all widget values from the specified node instead of just the value of a single widget.
  • Comfy dtype: BOOLEAN
  • Python dtype: bool

Output types

• string
  • Comfy dtype: STRING
  • The extracted widget value(s) as a string, which may represent a single widget's value or a concatenation of multiple widget values if 'return_all' is true.
  • Python dtype: str

Usage tips

• Infra type: CPU
• Common nodes: unknown
