class_name InputBinding extends SingleRefBinding
## Input binding for UI controls that support text/value changes
##
## Binds input controls (like LineEdit, SpinBox, ColorPicker) to reference values.
## Supports three types of input signals:
## - text_changed (for text inputs)
## - value_changed (for numeric inputs)
## - color_changed (for color pickers)
## Can bind to either direct values or object properties.

## The property name to bind to (empty for direct value binding)
var __property__: String

## The detected signal type ("text_changed", "value_changed", or "color_changed")
var __signal_type__: String
