Detailed Description
QwtPlotPanner provides panning of a plot canvas.
QwtPlotPanner is a panner for a QwtPlotCanvas, that adjusts the scales of the axes after dropping the canvas on its new position.
Together with QwtPlotZoomer and QwtPlotMagnifier powerful ways of navigating on a QwtPlot widget can be implemented easily.
- Note:
The axes are not updated, while dragging the canvas
