radio_group

`pdwidgets.widgets.radio_group`

Radio button group coordinator.

`RadioGroup(parent)`

Bases: Widget

Invisible coordinator that enforces single radio selection.

Initialize a RadioGroup to manage a group of RadioButtons.

RadioGroup is a real (but invisible, zero-size) :class:Widget so it participates in the widget tree for lifecycle consistency with every other widget. It draws nothing and is skipped by the dirty-rect render pass (invalidate and draw are no-ops). The member RadioButtons are normal children of their own parent; the group only tracks them for mutual exclusion.

Parameters:

Name	Type	Description	Default
`parent`	`Widget`	The parent widget or screen that owns this group.	required

`add(radio_button)`

Add a RadioButton to the group.

Parameters:

Name	Type	Description	Default
`radio_button`	`RadioButton`	The RadioButton to add to the group.	required

`draw(area=None)`

No-op: the group draws nothing.

`invalidate()`

No-op: an invisible, zero-size group never needs redrawing.

`set_checked(selected_button)`

Ensure only the selected button is checked in the group.

Parameters:

Name	Type	Description	Default
`selected_button`	`RadioButton`	The RadioButton to check.	required
