You only have to change one line... clearly too hard:

#include <QtGui>
#include <QDebug>
 
class Frame : public QFrame{
    Q_OBJECT
public:
    Frame( QWidget * parent = NULL ) : QFrame(parent){
        // setStyleSheet( "Frame{ background: blue }" );
        setStyleSheet( "Frame{ background-image: url(plasma.png); }" );
    }
protected:
    void paintEvent( QPaintEvent * event ){
        QFrame::paintEvent(event);
        QPainter p(this);
        p.drawLine( rect().topLeft(), rect().bottomRight() );
        p.drawText( rect().center(), "works!" );
    }
};
 
int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
 
    Frame m;
    m.show();
    return app.exec();
}
#include "main.moc"

#include <QtGui>
#include <QDebug>

class Frame : public QFrame{
    Q_OBJECT
public:
    Frame( QWidget * parent = NULL ) : QFrame(parent){
        // setStyleSheet( "Frame{ background: blue }" );
        setStyleSheet( "Frame{ background-image: url(plasma.png); }" );
    }
protected:
    void paintEvent( QPaintEvent * event ){
        QFrame::paintEvent(event);
        QPainter p(this);
        p.drawLine( rect().topLeft(), rect().bottomRight() );
        p.drawText( rect().center(), "works!" );
    }
};

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);

    Frame m;
    m.show();
    return app.exec();
}
#include "main.moc"

To copy to clipboard, switch view to plain text mode 

and it looks like:

with a 64x64 tile background.


If you do not share the errors then you cannot expect corrections.
