How to pass variables to slot methods in QT?

I\'m making a little chat messenger program, which needs a list of chat channels the user has joined. To represent this list graphically, I have made a list of QPushButton

if you're using Qt5, you can do it through lambda:

connect( sender, &Sender::valueChanged,  [=](){ myMethod(5); } );

void myMethod(int value)
{
  // do stuff
}
