| |
| RadioButton presents an option button that can be toggled on (checked) or |
| off (unchecked). Radio buttons are typically used to select one option |
| from a set of options. |
| |
| RadioButton inherits its API from \l AbstractButton. For instance, |
| you can set \l {AbstractButton::text}{text} and react to |
| \l {AbstractButton::clicked}{clicks} using the AbstractButton API. |
| The state of the radio button can be set with the |
| \l {AbstractButton::}{checked} property. |
| |
| Radio buttons are \l {AbstractButton::autoExclusive}{auto-exclusive} |
| by default. Only one button can be checked at any time amongst radio |
| buttons that belong to the same parent item; checking another button |
| automatically unchecks the previously checked one. For radio buttons |
| that do not share a common parent, ButtonGroup can be used to manage |
| exclusivity. |
| |
| \l RadioDelegate is similar to RadioButton, except that it is typically |
| used in views. |
