Signals
void	objectChanged ()

void	restoreEntryValuesChanged ()

void	isExplicitChanged ()

Signals inherited from QObject
void	destroyed (QObject *=nullptr)
	This signal is emitted immediately before the object obj is destroyed, after any instances of QPointer have been notified, and cannot be blocked.

void	objectNameChanged (const QString &objectName, QPrivateSignal)
	This signal is emitted after the object's name has been changed.

◆ isExplicit()

bool QQuickPropertyChanges::isExplicit ( ) const

\qmlproperty bool QtQuick::PropertyChanges::explicit

If explicit is set to true, any potential bindings will be interpreted as once-off assignments that occur when the state is entered.

In the following example, the addition of explicit prevents myItem.width from being bound to parent.width. Instead, it is assigned the value of parent.width at the time of the state change. \qml PropertyChanges { target: myItem explicit: true width: parent.width } \endqml

By default, explicit is false.
