◆ addButton

void QQuickButtonGroup::addButton ( QQuickAbstractButton * button )

slot

\qmlmethod void QtQuick.Controls::ButtonGroup::addButton(AbstractButton button)

Adds a button to the button group.

Note: Manually adding objects to a button group is typically unnecessary. The \l buttons property and the \l group attached property provide a convenient and declarative syntax.

By default, it is the first checked button added to an exclusive button group.

Qt::CheckState QQuickButtonGroup::checkState ( ) const

Since: QtQuick.Controls 2.4 (Qt 5.11) \qmlproperty enumeration QtQuick.Controls::ButtonGroup::checkState

This property holds the combined check state of the button group.

Available states: \value Qt.Unchecked None of the buttons are checked. \value Qt.PartiallyChecked Some of the buttons are checked. \value Qt.Checked All of the buttons are checked.

Setting the check state of a non-exclusive button group to Qt.Unchecked or Qt.Checked unchecks or checks all buttons in the group, respectively. Qt.PartiallyChecked is ignored.

Setting the check state of an exclusive button group to Qt.Unchecked unchecks the \l checkedButton. Qt.Checked and Qt.PartiallyChecked are ignored.

◆ isExclusive()

bool QQuickButtonGroup::isExclusive ( ) const

Since: QtQuick.Controls 2.3 (Qt 5.10) \qmlproperty bool QtQuick.Controls::ButtonGroup::exclusive

This property holds whether the button group is exclusive. The default value is true.

If this property is true, then only one button in the group can be checked at any given time. The user can click on any button to check it, and that button will replace the existing one as the checked button in the group.

In an exclusive group, the user cannot uncheck the currently checked button by clicking on it; instead, another button in the group must be clicked to set the new checked button for that group.

In a non-exclusive group, checking and unchecking buttons does not affect the other buttons in the group. Furthermore, the value of the \l checkedButton property is null.
