If the QBindable is invalid, a default constructed T is returned.ĭocumentation contributions included herein are the copyrights of Returns the underlying property's current value. See also binding, setBinding, and hasBinding. If the property does not have a binding, the returned QPropertyBinding will be invalid. Removes the currently set binding of the underlying property and returns it. QPropertyBinding QBindable:: takeBinding() See also value(), isValid(), isReadOnly(), and setBinding(). This function has no effect if the QBindable is read-only or invalid. This removes any currenltly set binding from it. Sets the underlying property's value to value. void QBindable:: setValue(const T & value) template QPropertyBinding QBindable:: setBinding( Functor f)Ĭreates a QPropertyBinding from f, and sets it as the underlying property's binding. See also binding, isReadOnly(), and isValid(). Does nothing if the QBindable is read-only or invalid. Sets the underlying property's binding to binding. QPropertyBinding QBindable:: setBinding(const QPropertyBinding & binding) QPropertyBinding QBindable:: makeBinding(const QPropertyBindingSourceLocation & location = QT_PROPERTY_DEFAULT_BINDING_LOCATION) constĬonstructs a binding evaluating to the underlying property's value, using a specified source location. Returns the currently set binding of the underlying property. QPropertyBinding QBindable:: binding() const See also QProperty, QObjectBindableProperty, and Qt Bindable Properties. To make a property that is usable directly without reading through a QBindable use QProperty or QObjectBindableProperty. This constructor should not be used to implement BINDABLE for a Q_PROPERTY, as the resulting Q_PROPERTY will not support dependency tracking. When binding using a lambda, you may prefer to capture the QBindable by value to avoid the cost of calling this constructor in the binding expression. You must use QBindable::value() in binding expressions instead of the normal property READ function (or MEMBER) to enable dependency tracking if the property is not BINDABLE. The property must have a notify signal but does not need to have BINDABLE in its Q_PROPERTY definition, so even binding unaware Q_PROPERTYs can be bound or used in binding expressions. See \l QBindable::QBindable( QObject *obj, const char *property) QBindable:: QBindable( QObject * obj, const char * property)Ĭonstructs a QBindable for the Q_PROPERTY property on obj.
