LiteralEvalLineEdit #

Bases: ValueWidget[str]

A one-line text editor that evaluates strings as python literals.

Parameters:

  • value (Any, default: Undefined ) –

    The starting value for the widget.

  • bind (Callable[[ValueWidget], Any] | Any, default: Undefined ) –

    A value or callback to bind this widget. If provided, whenever widget.value is accessed, the value provided here will be returned instead. bind may be a callable, in which case bind(self) will be returned (i.e. your bound callback must accept a single parameter, which is this widget instance).

  • nullable (bool, default: False ) –

    If True, the widget will accepts None as a valid value, by default False.

  • **base_widget_kwargs (Any, default: {} ) –

    All additional keyword arguments are passed to the base magicgui.widgets.Widget constructor.
