    Question How to focus line in QwtPlotMarker/QwtPlotScaleItem/QwtPlotPicker

    Hi All,

    I'm trying to draw a line using QwtPlotMarker or by QwtPlotScaleItem.
    And I'm using QwtPlotPicker to select the line and I got success, but it doesn't focus when I click on it.

    Now the question is, how I can set focus on that line either create by QwtPlotMarker or by QwtPlotScaleItem when I clicked on it.

    I can set width of that line, but looking for some focus functionality if it is their.

    Thanks

    Not sure, what you mean by focusing - guess you are talking about some sort of highlighting ?
    Then you can simply derive from QwtPlotMarker and add a selected state, where you draw the marker with a different QPen.
