| 23 | RadioButton presents an option button that can be toggled on (checked) or |
|---|
| 24 | off (unchecked). Radio buttons are typically used to select one option |
|---|
| 25 | from a set of options. |
|---|
| 26 | |
|---|
| 27 | RadioButton inherits its API from \l AbstractButton. For instance, |
|---|
| 28 | you can set \l {AbstractButton::text}{text} and react to |
|---|
| 29 | \l {AbstractButton::clicked}{clicks} using the AbstractButton API. |
|---|
| 30 | The state of the radio button can be set with the |
|---|
| 31 | \l {AbstractButton::}{checked} property. |
|---|
| 32 | |
|---|
| 33 | Radio buttons are \l {AbstractButton::autoExclusive}{auto-exclusive} |
|---|
| 34 | by default. Only one button can be checked at any time amongst radio |
|---|
| 35 | buttons that belong to the same parent item; checking another button |
|---|
| 36 | automatically unchecks the previously checked one. For radio buttons |
|---|
| 37 | that do not share a common parent, ButtonGroup can be used to manage |
|---|
| 38 | exclusivity. |
|---|
| 39 | |
|---|
| 40 | \l RadioDelegate is similar to RadioButton, except that it is typically |
|---|
| 41 | used in views. |
