QMap Signal/Slot issue

gian71

Hi, I have a problem with Signal and Slot.
I have an object that contains a QMap<quint64,QString> and other variable members. I emit the object as signal and receive it as slot. The object that I receive has all the members of the object emitted except the QMap which is empty.

I tried to qDebug() the map just before emit and in the slot and it looks like the map existed before and was empty after...

Can anybody help?

Thanks

Hi
Have you tested that Your class is copyable ?
I assume when the class is emitted its a copy and not the actual class, as in a pointer?

void TestFunc( YourClass A) { // no * or & here
is lists still filled here for A
}

--main--
YourClass mine;
// fill the qmap
TestFunc(mine);

Thanks for the answer.
Yes my object is copyable. I made a copy just before to emit the object and printed it out , the QMap...QMap is present in the copy, then I emit the object and I get it in the slot..the copy in the slot has QMap empty.

Hi,

Can you share the code where you emit the signal ?

Hi, it is my bad...mrjj was right, I did an incorrect test. The object is not copyable...I have to make it copyable first..that is the reason why I see the issue probably. Thanks
