\brief QwtPlotPanner provides panning of a plot canvas |
|
|
|
QwtPlotPanner is a panner for a plot canvas, 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 |
|
