Signal connected to multiple objects/slots - slots call order

kanito73

Hello friends

I have a doubt about the call order of slots... If I connect a single signal to more than one object/slot, the calls to the slot functions will follow the same order as they were connected?

For example:

QObject::connect ( this, SIGNAL(valueChanged(int)), object1, SLOT(slot1(int)) );
QObject::connect ( this, SIGNAL(valueChanged(int)), object2, SLOT(slot2(int)) );
QObject::connect ( this, SIGNAL(valueChanged(int)), object3, SLOT(slot3(int)) );

will it call slot1, slot2 and slot3, or they may be called in aleatory order?

Thanks for your comments

Hi, and welcome to the Qt Dev Net!

See the "QObject documentation":http://doc.qt.io/qt-5/qobject.html#connect-4:

They will follow the same order. You can refer to the documentation.
