.PP
\fBQwtPlotPanner\fP provides panning of a plot canvas\&.
\fBQwtPlotPanner\fP is a panner for a plot canvas, 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
