Hiding the title of a plot

[moijhd]

Hi,

I am trying to hide the title of a QwtPlot.

QwtPlot *plot = new QwtPlot();
// ...
plot->titleLabel()->setVisible(false)

QwtPlot *plot = new QwtPlot();
// ...
plot->titleLabel()->setVisible(false)

To copy to clipboard, switch view to plain text mode 

The title "blinks" but is not hidden.

I am on linux. It does not work on Windows XP.
The QwtTextLabel works fine.

Thanks.
