    Default event_filter Example

    Hello,

    why was the example: "event_filter" removed with Qwt 6.2.0? Thank you very much for an answer.

    Best regards,

    i am loooking for the best method to select a QwtPlotCurve with a mouse click. Should i use an event-filter or the QwtPlotPicker like in the example: "curve-tracker"?

    Thanks a lot! :-)

    The splineeditor example shows an example of how to select points of a curve.
    The curvetracker example has a faster implementation as it makes use of the fact that the points are sorted in x direction.

    HTH,
