class QwtDoublePoint

is fully implemented, but only available when PyQwt has been built for Qt-3. When PyQwt has been built for Qt-4, replace this class with QPointF except for in signals. For example, clicking in the canvas of the plot displayed canvas by the following program

#!/usr/bin/env python

import sys
from PyQt4 import Qt
import PyQt4.Qwt5 as Qwt

def aSlot(aQPointF):
    print 'aSlot gets:', aQPointF

# dummy()

def make():
    demo = Qwt.QwtPlot()
    picker = Qwt.QwtPlotPicker(Qwt.QwtPlot.xBottom,
                               Qwt.QwtPlot.yLeft,
                               Qwt.QwtPicker.PointSelection,
                               Qwt.QwtPlotPicker.CrossRubberBand,
                               Qwt.QwtPicker.AlwaysOn,
                               demo.canvas())
    picker.connect(picker, Qt.SIGNAL('selected(const QwtDoublePoint&)'), aSlot)
    return demo

# make()

def main(args):
    app = Qt.QApplication(args)
    demo = make()
    demo.show()
    sys.exit(app.exec_())

# main()

if __name__ == '__main__':
    main(sys.argv)

# Local Variables: ***
# mode: python ***
# End: ***

shows that the signal return on object of type QPointF:

aSlot gets: <PyQt4.QtCore.QPointF object at 0x2aaaaf73be20>
