Tiles also represent widgets that hold other widgets, such as columns, radio button groups and the dialogs themselves.
The two frames below have titles, and a radio button outside of them, presumably to select one or the other.
The choices are mutually exclusive; when the user selects a radio button, any previously selected radio button in the same group becomes deselected.
This state can not be restored by interacting with the radio button widget (but it may be possible through other user interface elements).
Each radio button is normally accompanied by a label describing the choice that the radio button represents.
Selecting a radio button is done by clicking the mouse on the button, or the caption, or by using a keyboard shortcut.
For this, a component needs to have an independent, and by the user perceivable and controllable state, such as a radio button, a slider or a whole word processor application.
Newt can be used to add stacked windows, entry widgets, checkboxes, radio buttons, labels, plain text fields, scrollbars, etc., to text user interfaces.
