Add icon from array to QListWidget item - c++

Question

I've written a loop which adds some items to my QListWidget. Now I want them to have an icon from my qrc file. For this I would use a loop in which I add a unique icon to each item.
void Test::Query()
{
ui->listWidget_Available->clear();
QString CmdList[4] = {"kcmshell4 --list|grep -q kcm_grub2",
"kcmshell4 --list|grep -q kcm_networkmanagement",
"which pastebunz",
"[ -z $ink3_ver ]"};
QString NameList[4] = {"kcm_grub2",
"kcm_networkmanagement",
"pastebunz",
"Shellmenu"};
QString IconList[4] = {":/icons/icons/GNU.png",
":/icons/icons/networkmanager.png",
":/icons/icons/edit-paste.png",
":/icons/icons/menu.png"};
QIcon ItemIcon;
int iCntSize = sizeof(CmdList) / sizeof(CmdList[0]);
Next thing is to clear the List:
for(int iItem = 0; iItem < iCntSize; iItem++)
{
ui->listWidget_Available->addItem(NameList[iItem]);
ui->listWidget_Available->item(iItem)->setCheckState(Qt::PartiallyChecked);
}
Now the ugly part:
for(int iRow = 0; iRow < iCntSize; iRow++)
{
int BarValue = ui->progressBar->value();
ui->progressBar->setValue(BarValue+(100/iCntSize));
QString status = QString("Processing index %1 of %2. Name: %3").arg(iRow).arg(iCntSize).arg(NameList[iRow]);
qDebug() << status << (BarValue+25);
And here is my problem:
ItemIcon.addFile(IconList[iRow], QSize(), QIcon::Normal, QIcon::Off);
ui->listWidget_Available->item(iRow)->setIcon(ItemIcon); <--- how to do THIS?
How can I do this?
ui->textEdit_Informations->append("Searching for "+NameList[iRow]);
mProcess = new QProcess();
mProcess->start("/bin/bash", QStringList() << "-c" << QString(CmdList[iRow]));
mProcess->waitForFinished();
if ( mProcess->exitStatus() == QProcess::CrashExit )
{
ui->textEdit_Informations->setTextColor(Qt::red);
ui->textEdit_Informations->append("\t[FATAL]");
}
else if ( mProcess->exitCode() != 0 )
{
ui->textEdit_Informations->setTextColor(Qt::magenta);
ui->textEdit_Informations->append("\t[MISSED]");
ui->listWidget_Available->item(iRow)->setCheckState(Qt::Unchecked);
}
else if ( mProcess->exitCode() == 0 )
{
ui->textEdit_Informations->setTextColor(Qt::green);
ui->textEdit_Informations->append("\t[FOUND]");
ui->listWidget_Available->item(iRow)->setCheckState(Qt::Checked);
}
ui->textEdit_Informations->setTextColor(Qt::white);
}
}
Any suggestions?

You should use the constructor and a new QIcon each time instead of QIcon::addFile:
QIcon ItemIcon(IconList[iRow]);
ui->listWidget_Available->item(iRow)->setIcon(ItemIcon);
addFile would only be useful if you had a different image for each state of the item the icon is in (normal, activated, disabled, ...).
