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
