Detailed Description

template<typename Class, typename T, auto Offset, auto Signal = nullptr>
class QObjectBindableProperty< Class, T, Offset, Signal >

\inmodule QtCore

The QObjectBindableProperty class is a template class that enables automatic property bindings for property data stored in QObject derived classes.

Since: 6.0

QObjectBindableProperty is a generic container that holds an instance of T and behaves mostly like \l QProperty. It is one of the classes implementing \l {Qt Bindable Properties}. Unlike QProperty, it stores its management data structure in the surrounding QObject. The extra template parameters are used to identify the surrounding class and a member function of that class acting as a change handler.

You can use QObjectBindableProperty to add binding support to code that uses Q_PROPERTY. The getter and setter methods must be adapted carefully according to the rules described in \l {Bindable Property Getters and Setters}.

In order to invoke the change signal on property changes, use QObjectBindableProperty and pass the change signal as a callback.

A simple example is given in the following.

#include <QObject>
#include <QProperty>
#include <QDebug>
 
class Foo : public QObject
{
    Q_OBJECT
    Q_PROPERTY(int myVal READ myVal WRITE setMyVal BINDABLE bindableMyVal)
public:
    int myVal() { return myValMember.value(); }
    void setMyVal(int newvalue) { myValMember = newvalue; }
    QBindable<int> bindableMyVal() { return &myValMember; }
signals:
    void myValChanged();
 
private:
    Q_OBJECT_BINDABLE_PROPERTY(Foo, int, myValMember, &Foo::myValChanged);
};
 
int main()
{
    bool debugout(true); // enable debug log
    Foo myfoo;
    QProperty<int> prop(42);
    QObject::connect(&myfoo, &Foo::myValChanged, [&]() {
        if (debugout)
            qDebug() << myfoo.myVal();
    });
    myfoo.bindableMyVal().setBinding([&]() { return prop.value(); }); // prints "42"
 
    prop = 5; // prints "5"
    debugout = false;
    prop = 6; // prints nothing
    debugout = true;
    prop = 7; // prints "7"
}
 
#include "main.moc"

QObjectBindableProperty is usually not used directly, instead an instance of it is created by using the Q_OBJECT_BINDABLE_PROPERTY macro.

Use the Q_OBJECT_BINDABLE_PROPERTY macro in the class declaration to declare the property as bindable.

class MyClass : public QObject
{
    Q_OBJECT
    Q_PROPERTY(int x READ x WRITE setX NOTIFY xChanged BINDABLE bindableX)
public:
    int x() const { return xProp; }
    void setX(int x) { xProp = x; }
    QBindable<int> bindableX() { return QBindable<int>(&xProp); }
 
signals:
    void xChanged();
 
private:
    // Declare the instance of the bindable property data.
    Q_OBJECT_BINDABLE_PROPERTY(MyClass, int, xProp, &MyClass::xChanged)
};

If you need to directly initialize the property with some non-default value, you can use the Q_OBJECT_BINDABLE_PROPERTY_WITH_ARGS macro. It accepts a value for the initialization as one of its parameters.

class MyClass : public QObject
{
    Q_OBJECT
    Q_PROPERTY(int x READ x WRITE setX NOTIFY xChanged BINDABLE bindableX)
public:
    int x() const { return xProp; }
    void setX(int x) { xProp = x; }
    QBindable<int> bindableX() { return QBindable<int>(&xProp); }
 
signals:
    void xChanged();
 
private:
    // Declare the instance of int bindable property data and
    // initialize it with the value 5.
    // This is similar to declaring
    // int xProp = 5;
    // without using the new QObjectBindableProperty class.
    Q_OBJECT_BINDABLE_PROPERTY_WITH_ARGS(MyClass, int, xProp, 5, &MyClass::xChanged)
};

Q_OBJECT_BINDABLE_PROPERTY_WITH_ARGS does not support multiple arguments directly. If your property requires multiple arguments for initialization, please explicitly call the specific constructor.

class CustomType
{
public:
    CustomType(int val, int otherVal) : value(val), anotherValue(otherVal) { }
 
private:
    int value = 0;
    int anotherValue = 0;
};
 
// later when using CustomType as a property
Q_OBJECT_BINDABLE_PROPERTY_WITH_ARGS(MyClass, CustomType xProp, CustomType(5, 10),
                                     &MyClass::xChanged)

The change handler can optionally accept one argument, of the same type as the property, in which case it is passed the new value of the property. Otherwise, it should take no arguments.

If the property does not need a changed notification, you can leave out the "NOTIFY xChanged" in the Q_PROPERTY macro as well as the last argument of the Q_OBJECT_BINDABLE_PROPERTY and Q_OBJECT_BINDABLE_PROPERTY_WITH_ARGS macros.

inline

Subscribes the given functor f as a callback that is called whenever the value of the property changes.

The callback f is expected to be a type that has a plain call operator {()} without any parameters. This means that you can provide a C++ lambda expression, a std::function or even a custom struct with a call operator.

The returned property change handler object keeps track of the subscription. When it goes out of scope, the callback is unsubscribed.

This method is in some cases easier to use than onValueChanged(), as the returned object is not a template. It can therefore more easily be stored, e.g. as a member in a class.

Programmatically signals a change of the property.

Any binding which depend on it will be notified, and if the property has a signal, it will be emitted.

This can be useful in combination with setValueBypassingBindings to defer signalling the change until a class invariant has been restored.

Note: If this property has a binding (i.e. hasBinding() returns true), that binding is not reevaluated when notify() is called. Any binding depending on this property is still reevaluated as usual.
