.SS "QRect QwtPlainText::boundingRect (QPainter * painter = \fC0\fP) const\fC [virtual]\fP"
.PP
Returns the bounding rectangle. 
.PP
The bounding rectangle is calculated with respect to (0, 0). The left and top border depend on the alignment flags:
.IP "\(bu" 2
the left border is at -width, -width/2 or 0 for Qt::AlignRight, Qt::AlignHCenter or Qt::AlignLeft respectively
.IP "\(bu" 2
the top border is at 0, -height/2 or -height for Qt::AlignTop, Qt::AlignVCenter or Qt::AlignBottom respectively
.PP
.PP
Use for instance QRect::moveBy(x,y), before drawing the text into the rectangle.
