What "Parentheses" am I missing ?

Anonymous_Banned275

Complier / linked give no errors.
Code runs with TWO problems

In run time I get missing parentheses
and
I am not sure what "trigger" am I expecting.

I am just highlighting the selection
but I have a check box I like to see as a trigger.

Will probably work better AFTER I fix the Parentheses issue .

PLEASE
NO suggestions to use lambda, maybe later.

for (int index = 0; index < list_hcitool.size(); ++index)
                {
                    text = "Add subsubmenu";
                    subtempmenu = new QMenu();
                    subtempmenu->setTitle(list_hcitool[index] + " #" + QString::number(index));
                    subMenu[index]  = tempmenu; //m_ui->menuWindow_cpntrol;
                    subAction[index] = subMenu[index]->addMenu(subtempmenu);
                    subAction[index]->setVisible(true);
                    subAction[index]->setCheckable(true);

                    qDebug() << list_hcitool[index];

                    // connect here ??
                    connect(subAction[index],SIGNAL(triggered),this,SLOT(testSlot()));

                }

Here is run time message...

QObject::connect: Parentheses expected, signal QAction::triggered in mainwindow_Bluetooth.cpp:1587
QObject::connect:  (receiver name: 'MainWindow_Bluetooth')

@AnneRanch said in What "Parentheses" am I missing ?:

SIGNAL(triggered)

THis is the parenttheses issue,

SIGNAL(triggered() )

and then I am miss WHO will trigger

SIGNAL(triggered(... actual trigger here ...) )

@AnneRanch https://doc.qt.io/qt-5/qaction.html#triggered
you need a bool there.

@AnneRanch
The recommended way is:
connect(subAction[index], &yourClass::triggered, this, &thisClass::testSlot);
