Connecting many SIGNALS to SLOTS

[Vikram.Saralaya]

for(int i=0; i<100; ++i)
        QObject::connect(&chb[i], SIGNAL(stateChanged(int)), &lndt[i], SLOT(setText(QString));

for(int i=0; i<100; ++i)
        QObject::connect(&chb[i], SIGNAL(stateChanged(int)), &lndt[i], SLOT(setText(QString));

To copy to clipboard, switch view to plain text mode 

Ps: QCheckbox emits stateChanged signal not textChanged
