Check delegates are typically used to select one or more - options from a set of options in a list. For smaller sets of options, or - for options that need to be uniquely identifiable, consider using - \l CheckBox instead. - - CheckDelegate inherits its API from \l ItemDelegate, which is inherited - from 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 check delegate can be set with the - \l {AbstractButton::}{checked} property. - - In addition to the checked and unchecked states, there is a third state: - partially checked. The partially checked state can be enabled using the - \l tristate property. This state indicates that the regular checked/unchecked - state can not be determined; generally because of other states that affect - the check delegate. This state is useful when several child nodes are selected - in a treeview, for example. - - \code - ListView { - model: ["Option 1", "Option 2", "Option 3"] - delegate: CheckDelegate { - text: modelData - } - } - \endcode - - \sa {Customizing CheckDelegate}, {Delegate Controls}, CheckBox -*/ - -class QQuickCheckDelegatePrivate : public QQuickItemDelegatePrivate -{ - Q_DECLARE_PUBLIC(QQuickCheckDelegate) - -public: - void setNextCheckState(const QJSValue &callback); - - QPalette defaultPalette() const override { return QQuickTheme::palette(QQuickTheme::ListView); } - - bool tristate = false; - Qt::CheckState checkState = Qt::Unchecked; - QJSValue nextCheckState; -}; - -void QQuickCheckDelegatePrivate::setNextCheckState(const QJSValue &callback) -{ - Q_Q(QQuickCheckDelegate); - nextCheckState = callback; - emit q->nextCheckStateChanged(); -} - -QQuickCheckDelegate::QQuickCheckDelegate(QQuickItem *parent) - : QQuickItemDelegate(*(new QQuickCheckDelegatePrivate), parent) -{ - setCheckable(true); -} - -/*! - \qmlproperty bool QtQuick.Controls::CheckDelegate::tristate - - This property determines whether the check delegate has three states. - - In the animation below, the first checkdelegate is tri-state: - - \image qtquickcontrols2-checkdelegate-tristate.gif - - The default is \c false, i.e., the delegate has only two states. -*/ -bool QQuickCheckDelegate::isTristate() const -{ - Q_D(const QQuickCheckDelegate); - return d->tristate; -} - -void QQuickCheckDelegate::setTristate(bool tristate) -{ - Q_D(QQuickCheckDelegate); - if (d->tristate == tristate) - return; - - d->tristate = tristate; - emit tristateChanged(); -} - -/*! - \qmlproperty enumeration QtQuick.Controls::CheckDelegate::checkState - - This property determines the check state of the check delegate. - - Available states: - \value Qt.Unchecked The delegate is unchecked. - \value Qt.PartiallyChecked The delegate is partially checked.
