详细描述

A RadioButton is an option button that can be switched on (checked) or off (unchecked). Radio buttons typically present the user with a "one of many" choices. In a group of radio buttons, only one radio button can be checked at a time; if the user selects another button, the previously selected button is switched off.

GroupBox {
    title: "Tab Position"
    RowLayout {
        ExclusiveGroup { id: tabPositionGroup }
        RadioButton {
            text: "Top"
            checked: true
            exclusiveGroup: tabPositionGroup
        }
        RadioButton {
            text: "Bottom"
            exclusiveGroup: tabPositionGroup
        }
    }
}
					

You can create a custom appearance for a RadioButton by assigning a RadioButtonStyle .
