[Qt-interest] [QT & GDI handle]Where is my GDI handle?

[lvbing lvbing]

Hi all,
I  have an application to draw like rectangle,line,text etc.now,I meet a
trouble:when I user the QPainter to drawText like this:

void MyDrawArea::Draw(QPainter painter)
{
    QFont font = getFont();
    painter.setFont(font);
    QString drawText = getDrawText();
    painter.drawText( ......); //The para for drawtext
}

now the program is:if the font bold is true,my program's GDI will be
increase until the GDI handle equal to 10,000,and then crashed.

who know why I use the QPainter's setFont,but my GDI handle increase to
10,000?

BTW:my platform is WIN XP,and the QT's version is QT3.3.2.

BTW:if  I set the font is normal,the GDI handle will OK.
Thax:)
