calling a funktion with Slot

[BenHarper9]

Hallo everyone,

ich have a little problem in my code:
i want to connect a button with a funktion that i defined in the main.cpp

but it does not work in this way

kann someone help me??

void playMe()
{
QSound s("C://test.wav");
s.play();
}

int main(int argc, char *argv[])
{
QPushButton *cover1 = new QPushButton;
QObject::connect(cover1, SIGNAL(clicked()), this, SLOT(playMe()));
}

Slot should be a slot of a class derived from QObject with Q_OBJECT macro.
More details as usually in the documentation

A little hint:

Always capture the return code from connect() and test it with an assert:

bool rc = connect(...);
Q_ASSERT(rc);
Q_UNUSED(rc);

(The Q_UNUSED prevents the compiler from complaining about an unused variable when compiled without debug enable.)

This way you always can be sure that your connect actually "took".
