loadPixmap returns true but does not display/show on-screen

[Halordain]

Thank you! I changed it, changed my pathname, and got it to build without any warning messages....... but nothing shows up.

QString qindex = itoa(index, buffer, 10);
            QString filename("img/");
            filename += qindex;
            filename += ".png";
 
if (!qimg.load(filename))
                qWarning("Failed to load target image");
 if (qimg.isNull())
                qWarning("Failed to load target image");
 
            img_board[j][i] = new QLabel;
            img_board[j][i]->setPixmap(qimg);
 
            if (img_board[j][i] == NULL)
                qWarning("Failed to load target image");

QString qindex = itoa(index, buffer, 10);
            QString filename("img/");
            filename += qindex;
            filename += ".png";

if (!qimg.load(filename))
                qWarning("Failed to load target image");
 if (qimg.isNull())
                qWarning("Failed to load target image");

            img_board[j][i] = new QLabel;
            img_board[j][i]->setPixmap(qimg);

            if (img_board[j][i] == NULL)
                qWarning("Failed to load target image");

To copy to clipboard, switch view to plain text mode 

...where, in the .h file, I define...

vector<vector<QLabel*> > img_board;

vector<vector<QLabel*> > img_board;
