will help you For these cases it is better to use a QPainterPathStroker and pass it a QPainterPath that I have the round rectangle with addRoundedRect():
def paintEvent(self, event):
    pen = QtGui.QPen()
    brush = QtGui.QBrush(QtCore.Qt.black)
    painter = QtGui.QPainter(self)
    painter.setRenderHint(QtGui.QPainter.Antialiasing)
    painter.setPen(pen)
    painter.setBrush(brush)

    painter.translate(self.rect().center())
    painter.scale(self._factor, self._factor)
    painter.translate(-self.rect().center())

    painter.translate(self._pos)
    painter.drawPath(self._path)

    S = (self._rectouter.size() + self._rectinner.size())/2
    s = (self._rectouter.size() - self._rectinner.size())/2
    r = QtCore.QRectF(QtCore.QPointF(), S)
    r.moveCenter(self._rectouter.center())
    path = QtGui.QPainterPath()
    painter.setBrush(QtGui.QBrush(QtCore.Qt.gray, QtCore.Qt.Dense7Pattern))

    if self._type == QtGui.QRegion.Rectangle:
        painter.drawRect(self._rect)
        path.addRoundedRect(r, 20, 20)

    elif self._type == QtGui.QRegion.Ellipse:
        painter.drawEllipse(self._rect)
        path.addEllipse(r)

    stroker = QtGui.QPainterPathStroker()
    stroker.setWidth(s.width())
    stroke_path = stroker.createStroke(path)
    # painter.setPen(QtCore.Qt.NoPen)
    painter.setBrush(QtGui.QBrush(QtCore.Qt.cyan, QtCore.Qt.SolidPattern))
    painter.drawPath(stroke_path)

LWUIT Painter : How to draw a line on top of a Image Label?

seems to work fine You need to apply the painter to Unselected and Selected style since you give the label focus. You are also drawing a diagonal line not a strait line.

With these it helps You can use Qt SVG module. If you are using qmake, add QT += svg to your .pro file and then you will be able to use SVG classes. Then, you can utilize QSvgRenderer to draw svg documents with your QPainter instance like:
#include <QSvgRenderer>
...
void MainWindow::paintEvents(QPaintEvent *event) {
    QPainter painter(this);
    QSvgRenderer svgr("/path/to/img.svg");
    svgr.render(&painter);
    painter.end();
}

it should still fix some issue Extend your figure from org.eclipse.draw2d.ImageFigure class.
In constructor you can pass org.eclipse.swt.graphics.Image which can be passed to super class.
