Detailed Description

A safe and scoped wrapper around QObject::blockSignals() of multiple objects.

A ScopedMultiSignalsBlocker allows to disable the signals of multiple QObjects for the scope of a particular block. It sets the QObject's signalsBlocked property to true when they are added (by operator <<), and resets its to its previous state during destruction.

Synopsis:

{
    ScopedMultiSignalsBlocker block(my_widget, my_other_widget);
    my_widget->setSomeProperty("Hello World");
}

{
    ScopedMultiSignalsBlocker block;
    block << my_widget << my_other_widget;
    my_widget->setSomeProperty("Hello World");
}
