edifice.RadioButton

class edifice.RadioButton(checked=False, text='', on_change=None, **kwargs)

Bases: QtWidgetElement[EdRadioButton]

Radio buttons.

• Underlying Qt Widget QRadioButton

Radio buttons are used to specify a single choice out of many.

Props

All props from QtWidgetElement plus:

Parameters:

• checked (bool) – Whether or not the RadioButton is checked.

• text (str) – Text for the label of the RadioButton.

• on_change (Optional[Callable[[bool], Optional[Awaitable[None]]]]) – Event handler for when the checked value changes, but only when the user checks or unchecks, not when the checked prop changes.

Usage

Three RadioButtons

Because of the declarative nature of Edifice, we can ignore all of the Qt mechanisms for radio button “groups” and “exclusivity.” Just declare each radio button checked prop to depend on the state.

Exclusive RadioButtons with different parents

value, value_set = use_state(cast(Literal["op1", "op2"], "op1"))

with ed.VBoxView():
    with ed.VBoxView():
        ed.RadioButton(
            checked = value == "op1",
            on_change = lambda checked: value_set("op1") if checked else None,
            text = "Option 1",
            style = {} if value == "op1" else { "color": "grey" },
        )
    with ed.VBoxView():
        ed.RadioButton(
            checked = value == "op2",
            on_change = lambda checked: value_set("op2") if checked else None,
            text = "Option 2",
            style = {} if value == "op1" else { "color": "grey" },
        )
