Appropriate places to connect button to slots

[slava_xd]

I'm making a QT widgets application(it'll be opensource and I want to write it the cleaneast way possible) with visual studio I already have the whole UI set up using the QTDesigner. Now, my question is, now that I have the buttons and the functions, it's time to connect them via the connect function, like so:

connect(ui.pushButton, SIGNAL(clicked()), this, SLOT(ButtonActionNow()));

what i want to know is where should I set this up? I mean, should I call connect in the application constructor like:

QtWidgetsApplication1::QtWidgetsApplication1(QWidget *parent)
    : QMainWindow(parent)
{
    ui.setupUi(this);
    connect(ui.pushButton, SIGNAL(clicked()), this, SLOT(ButtonActionNow()));
}

or maybe inside the ui.setup function? What do people generally?

Since this function is automatically generated this would be a wrong place.
Connect them in the ctor for the ui stuff. And please don't use the old signal-slot syntax but the current one to get compile time errors instead at runtime.

@Christian-Ehrlicher how do i use the new syntax if I created all the buttons with the designer ?

Click on my link. I don't see any relation on where you created the widgets though.
