Bug 451016

Description of problem: I need to run some Qt3 applications with disabled libXft
font rendering. After upgrading from Fedora 8 to Fedora 9 all those applications
stopped working correctly. Instead of fonts I see some unreadable garbage.

Version-Release number of selected component (if applicable):

How reproducible: Always

Steps to Reproduce:

1) install g++, qt3 and qt3 devel

2) cat main.cpp

#include <qapplication.h>
#include <qfont.h>
#include <qlabel.h>
#include <qframe.h>
#include <qlayout.h>
#include <qpushbutton.h>
#include <qfontdialog.h>

static bool s_antialias;

class MyWidget : public QFrame
{
    Q_OBJECT

    public:
        MyWidget(QWidget *parent = 0);
        void setVTFont(const QFont& f);
    public slots:
        void editFont();
};

#include "main.moc"

MyWidget::MyWidget(QWidget *parent) : QFrame(parent)
{
    s_antialias = true;
    QLabel *label = new QLabel("This is sample text", this);
    QPushButton *button = new QPushButton("Change Font...", this);
    connect(button, SIGNAL(clicked()), this, SLOT(editFont()));

    QVBoxLayout *layout = new QVBoxLayout(this);
    layout->addWidget(button);
    layout->addWidget(label);
}

void MyWidget::editFont()
{
    bool ok;
    QFont font = QFontDialog::getFont(
                    &ok, QFont( "Helvetica [Cronyx]", 10 ), this );
    if(ok)
    {
        setVTFont(font);
    }
}

void MyWidget::setVTFont(const QFont& f)
{
    QFont font = f;
    if (!s_antialias)
        font.setStyleStrategy( QFont::NoAntialias );
    QFrame::setFont(font);
    fontChange(font);
}

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

    MyWidget *widget = new MyWidget;

    QString str(app.argv()[1]);
    if(str == "--noxft")
        s_antialias = false;

    widget->setVTFont(app.font());

    widget->show();
    app.setMainWidget(widget);
    return app.exec();
}

qmake -project
qmake
make

./application --noxft
  
Actual results: Garbage

Expected results: Normal font rendering

Additional info: I have tested this problem with nv and nvidia drivers.
