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 AbstractButton . For instance, you can set text and react to clicks 使用 AbstractButton API. The state of the radio button can be set with the checked 特性。
单选按钮是 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.
RadioDelegate 类似于 RadioButton , except that it is typically used in views.
ColumnLayout {
RadioButton {
checked: true
text: qsTr("First")
}
RadioButton {
text: qsTr("Second")
}
RadioButton {
text: qsTr("Third")
}
}
