Find a issue when invoking QComboBox::setItemText on MacOS X
The invocation is quite simple, like below:
QComboBox* combo = new QComboBox(parent);
int index = combo->findData(Id);
if(combo->itemText(index) == Id)
QString name = getNameById(Id);
At runtime, I'll get the error message saying:
QObject::connect: Cannot queue arguments of type 'QVector<int>'
(Make sure 'QVector<int>' is registered using qRegisterMetaType().)
As long as making the line "combo->setItemText(index, name);" an annotation with "//", the message will go away. Anybody there has the same question?
Pretty strange because the error seems to be completely unrelated to QComboBox.
Do you use a QVector<int> anywhere in your program in a signal or slot signature ?
Can you create a minimal compilable example from scratch that reproduces this ?
