I have a different purpose accounts,There are a number of transmit and receive daily,I need to count the daily changes in accounts, including the payment amount and the number of payments. So I developed a simple report class.

I add reportview.h and reportview.cpp, Some of the code released. I intend to put them to use GridView to display, need to continue to improve . :)

void ReportView::showTotal()

{

float fTotal=0;

float iTotal=0;

int i=0;

QString addressname = "";

QVector<QString> addresslist;

QVector<float> totallist;

QVector<float> timelist;

//accountReport from every address

for (i=0;i<=transactionProxyModel->rowCount();i++)

{

fTotal+=transactionProxyModel->data(transactionProxyModel->index(i,4)).toFloat();

iTotal=transactionProxyModel->data(transactionProxyModel->index(i,4)).toFloat();

addressname=transactionProxyModel->data(transactionProxyModel->index(i,3)).toString();

int t = addresslist.indexOf(addressname);

if (t != -1)

{

totallist[t]=totallist.at(t)+iTotal;

timelist[t]=timelist.at(t)+1;

}

else

{

addresslist.append(addressname);

totallist.append(iTotal);

timelist.append(1);

}

}

totalnumslWidget->setText("Date:"+dateWidget->currentText()+" Type:"+typeWidget->currentText()+" "+QObject::tr("%1").arg(fTotal)+" FTC");

totaltimesWidget->setText(QObject::tr("%1").arg(i)+" times payment");

QString account = "";

for (int i=0;i!=addresslist.size();++i)

{

account.append(addresslist.at(i)+" Total:"+QObject::tr("%1").arg(totallist.at(i))+" "+QObject::tr("%1").arg(timelist.at(i))+" times payment \n");

rptTotal->setText(account);

}

}
