prob on connect

[mickey]

Hi I need to do connect below; is there a way? thanks

vector <QPushButton*> pb;
pb.push_back(pushButton0); 
................
connect(pb[i], SIGNAL(clicked()), this, SLOT(mySlot(i)));

vector <QPushButton*> pb;
pb.push_back(pushButton0); 
................
connect(pb[i], SIGNAL(clicked()), this, SLOT(mySlot(i)));

To copy to clipboard, switch view to plain text mode

Use QSignalMapper. You must register your QObject using QSignalMapper::setMapping() and connect it to QSignalMapper::map() slot. Then you have to connect the mapper to mySlot().

Either you will need to subclass QPushButton and reimplement keyEvents and mouseEvents.

Or you will need to have separate slots for each button like this.

vector <QPushButton*> pb;
pb.push_back(pushButton0);
pb.push_back(pushButton1);
..........................
connect(pushButton0, SIGNAL(clicked()), this, SLOT(butto0Slot())); 
connect(pushButton1, SIGNAL(clicked()), this, SLOT(butto1Slot()));

vector <QPushButton*> pb;
pb.push_back(pushButton0);
pb.push_back(pushButton1);
..........................
connect(pushButton0, SIGNAL(clicked()), this, SLOT(butto0Slot())); 
connect(pushButton1, SIGNAL(clicked()), this, SLOT(butto1Slot()));

Subclass QPushButton class and define an overloaded clicked signal.

signals:
void clicked(int);

signals:
void clicked(int);

To copy to clipboard, switch view to plain text mode 

and a private slot

void reEmitClicked();

void reEmitClicked();

To copy to clipboard, switch view to plain text mode 

Now in the constructor connect the above two

connect(this, SIGNAL(clicked()), this, SLOT(reEmitClicked()));

connect(this, SIGNAL(clicked()), this, SLOT(reEmitClicked()));

To copy to clipboard, switch view to plain text mode 

Now in the defination of reEmitClicked(), emit your overloaded clicked signal.

emit clicked(i);

emit clicked(i);

To copy to clipboard, switch view to plain text mode 

Now use this overloaded clicked signal, instead of the previous one.
Note: Keep i as a member or property of your class which you can pass through th ctor.
