Can I add padding to a QwtText object?

KelvinSP

I am adding a QwtPlotMarker to a QwtPlot using the following code:

QwtPlotMarker *tooltip = new QwtPlotMarker(tr("Tooltip"));

QwtText label("02/01/17\n06:00:00\nVoltage: 4.02");
QColor blue(QColor(30, 140, 220));
label.setColor(blue);
label.setBorderPen(QPen(blue, 1));
label.setBorderRadius(5);
label.setBackgroundBrush(QColor(65, 177, 225, 50));

QFont font("MS Shell Dlg 2", 8);
label.setFont(font);

tooltip->setLabel(label);
tooltip->setLabelAlignment(Qt::AlignCenter | Qt::AlignTop);    
tooltip->attach(this);

this->replot();

where this points to a QwtPlot object.

With the code above I'm getting the following result:

Note that in the image the letter V from the Voltage is overlapped by the border.

Is it possible to add padding to the QwtText (or maybe to the QwtPlotMarker!?), so I can get a result like the following one?

I'm using Qt 5.3.2 and Qwt 6.1.0.

Qwt has its own forum. and mailing list.
I would rather seek for advice there.
