In these cases, regular property binding doesn't work. Binding - allows you to bind any value to any property. - - For example, imagine a C++ application that maps an "app.enteredText" - property into QML. You could use Binding to update the enteredText property - like this. - \code - TextEdit { id: myTextField; text: "Please type here..." } - Binding { target: app; property: "enteredText"; value: myTextField.text } - \endcode - Whenever the text in the TextEdit is updated, the C++ property will be - updated also. - - If the binding target or binding property is changed, the bound value is - immediately pushed onto the new target. - - \sa QtDeclarative -*/ -QDeclarative1Bind::QDeclarative1Bind(QObject *parent) - : QObject(*(new QDeclarative1BindPrivate), parent) -{ -} - -QDeclarative1Bind::~QDeclarative1Bind() -{ -} - -/*! - \qmlproperty bool QtQuick1::Binding::when - - This property holds when the binding is active. - This should be set to an expression that evaluates to true when you want the binding to be active. - - \code - Binding { - target: contactName; property: 'text' - value: name; when: list.ListView.isCurrentItem - } - \endcode -*/ -bool QDeclarative1Bind::when() const -{ - Q_D(const QDeclarative1Bind); - return d->when; -} - -void QDeclarative1Bind::setWhen(bool v) -{ - Q_D(QDeclarative1Bind); - d->when = v; - eval(); -} - -/*! - \qmlproperty Object QtQuick1::Binding::target - - The object to be updated. -*/ -QObject *QDeclarative1Bind::object() -{ - Q_D(const QDeclarative1Bind); - return d->obj; -} - -void QDeclarative1Bind::setObject(QObject *obj) -{ - Q_D(QDeclarative1Bind); - d->obj = obj; - eval(); -} - -/*! - \qmlproperty string QtQuick1::Binding::property - - The property to be updated. -*/ -QString QDeclarative1Bind::property() const -{ - Q_D(const QDeclarative1Bind); - return d->prop; -} - -void QDeclarative1Bind::setProperty(const QString &p) -{ - Q_D(QDeclarative1Bind); - d->prop = p; - eval(); -} - -/*! - \qmlproperty any QtQuick1::Binding::value - - The value to be set on the target object and property.
