[Qt-interest] Extending the context menu of a QDoubleSpinBox

[Emmanuel Mayssat]

The best way I found to implement this is to subclass QDoubleSpinBox
and reimplement the contextMenuEvent method following the one defined
in QAbstract

http://cep.xor.aps.anl.gov/software/qt4-x11-4.2.2-browser/d5/d8d/qabstractspinbox_8cpp-source.html

    def contextMenuEvent(self, event):
        menu = self.lineEdit().createStandardContextMenu()
        menu.addSeparator()
        se = self.stepEnabled()
        self.stepUpAction.setEnabled(se & QAbstractSpinBox.StepUpEnabled)
        self.stepDownAction.setEnabled(se & QAbstractSpinBox.StepDownEnabled)
        self._addActions_(menu, ( self.setStepSizeAction, None,
self.stepUpAction, self.stepDownAction, self.newAction))
        menu.exec_(event.globalPos())
