I'm using QwtPlotMagnifier to be able to zoom in the curves, but I want also that the thick of the curves will magnify itself, changing the curve pen thick like under a glass.
How should be possible?
You have to manipulate the curve pens in your code - f.e by deriving from QwtPlotCurve and reimplementing updateScaleDiv().
