QT no such slot

Hi everyone,

I'm trying to modify the sources codes of wireshark QT but apparently I can't add new slots. I mean i added in main_windows.h my declaration,

void PingCouter();

in mainwindows_slot.cpp my code

void MainWindow::PingCounter()
{
plugin_test *test = new plugin_test(this);
test->show();
}

and in main_windows.cpp my connect slot

  QAction *Ping_Counter = new QAction;
connect(Ping_Counter, SIGNAL(triggered()), this, SLOT(PingCounter()));

I have no compilation errors but i have a runtime message :

  QObject::connect: No such slot MainWindow::PingCounter()
QObject::connect:  (receiver name: 'MainWindow')

I watched in mocmainwindows.cpp to be sure that my slot was here but it is not. therefore i think there is a problem here but i don’t know how to resolve this one.

thanks for your help
