.SH "Detailed Description"
.PP 
\fBQwtPlotPanner\fP provides panning of a plot canvas. 

\fBQwtPlotPanner\fP is a panner for a \fBQwtPlotCanvas\fP, that adjusts the scales of the axes after dropping the canvas on its new position.
.PP
Together with \fBQwtPlotZoomer\fP and \fBQwtPlotMagnifier\fP powerful ways of navigating on a \fBQwtPlot\fP widget can be implemented easily.
.PP
\fBNote:\fP
.RS 4
The axes are not updated, while dragging the canvas
