Qt in visual studio: connecting slots and signals doesn't work.

Question

Hi,

I have installed Qt and Qt for VS plugin. Everything works fine, UI applications compile and run that's ok, but connecting signals and slots doesn't. I have Q_OBJECT in my class and for connecting I am using this code in constructor:

connect(ui.mainTableView, SIGNAL(activated(const QModelIndex &)),
        this, SLOT(showDetail(const QModelIndex &)));

EDIT:

showDetail method:

void MyClass::showDetail(const QModelIndex &index)
{
    this->setWindowTitle("it works");
}

window title is not changed and breakpoint is not reached.

moc files are generated in Generated Files directory, but moc file of that class is empty (others not), I think that it is because the class has no signal, but only one slot.

even connections generated by Designer don't work and the call of connect method returns true.

Answer 1

Have you got the moc working correctly? That would explain why the connect isn't doing its thing, but everything else is...

Answer 2

Remove variable names from SIGNAL and SLOT macros:

connect(ui.mainTableView, SIGNAL(activated(const QModelIndex &)),
    this, SLOT(showDetail(const QModelIndex &)));

For more details, read documentation on QObject::connect carefully.

Answer 3

RESULT:

Oh no it turns out to be a silly question, thanks everybody, all answers pushed me towards the solution, but the last step was to find out that on my platform items are activated only by double-click, not single. Sorry
