How to pass variables to slot methods in QT?

Question

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

Answer 1

You could try having your switchTab slot take no argument and use QObject::sender to get the object that sent the signal.

Messenger::switchTab()
{
  QObject* sender = this->sender();
  QPushButton* button = qobject_cast(sender);
  if(button)
  {
    // Do stuff...
  }
}
