Hi, again. :)

As with the last few times I posted here, I have a question about QT, which I am using to create a chat messenger client. To display the list of online users, I'm using a QListWidget, as created like this:

listWidget = new QListWidget(horizontalLayoutWidget);
listWidget->setObjectName("userList");
QSizePolicy sizePolicy1(QSizePolicy::Preferred, QSizePolicy::Expanding);
sizePolicy1.setHorizontalStretch(0);
sizePolicy1.setVerticalStretch(0);
sizePolicy1.setHeightForWidth(listWidget->sizePolicy().hasHeightForWidth());
listWidget->setSizePolicy(sizePolicy1);
listWidget->setMinimumSize(QSize(30, 0));
listWidget->setMaximumSize(QSize(150, 16777215));
listWidget->setBaseSize(QSize(100, 0));
listWidget->setContextMenuPolicy(Qt::CustomContextMenu);

Users are shown by constantly refreshing the list, like this: (Note: There are different channels, with different userlists, so refreshing it is the most efficient thing to do, as far as I know.)

void FMessenger::refreshUserlist()
{
    if (currentPanel == 0)
        return;
    listWidget = this->findChild<QListWidget *>(QString("userList"));
    listWidget->clear();
    QList<FCharacter*> charList = currentPanel->charList();
    QListWidgetItem* charitem = 0;
    FCharacter* character;
    foreach(character, charList)
    {
        charitem = new QListWidgetItem(character->name());
        // charitem->setIcon(QIcon(":/Images/status.png"));
        listWidget->addItem(charitem);
    }
}

This has always worked perfectly. The line that I commented out is the one I have problems with: my current goal is to be able to display a user's online status with an image, which represents whether they are busy, away, available, etc. Using setIcon() does absolutely nothing though, apparently; the items still show up as they used to, without icons.

I'm aware that this is probably not the way this function needs to be used, but I have found little documentation about it online, and absolutely no useful examples of implementations. My question is, can anybody help me with fixing this problem? Any help would be appreciated terrifically, like always!
