◆ isExplicit()

bool QQuickPropertyChanges::isExplicit ( ) const

\qmlproperty bool QtQuick::PropertyChanges::explicit

If explicit is set to true, bindings will be interpreted as assignments. The expression will only be evaluated once, and no updates happen, even if dependencies change.

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.

This property holds whether the previous values should be restored when leaving the state.
