19 \brief QwtPlotPanner provides panning of a plot canvas
20
21 QwtPlotPanner is a panner for a plot canvas, that
22 adjusts the scales of the axes after dropping
23 the canvas on its new position.
24
25 Together with QwtPlotZoomer and QwtPlotMagnifier powerful ways
26 of navigating on a QwtPlot widget can be implemented easily.
27
28 \note The axes are not updated, while dragging the canvas
29 \sa QwtPlotZoomer, QwtPlotMagnifier
