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.
| QwtPlotPanner::QwtPlotPanner | ( | QwtPlotCanvas * | canvas | ) | [explicit] |
Create a plot panner.
The panner is enabled for all axes
| canvas | Plot canvas to pan, also the parent object |
| QwtPlotPanner::~QwtPlotPanner | ( | ) | [virtual] |
Destructor.
| const QwtPlotCanvas * QwtPlotPanner::canvas | ( | ) | const |
Return Observed plot canvas.
| QwtPlotCanvas * QwtPlotPanner::canvas | ( | ) |
Return observed plot canvas.
| bool QwtPlotPanner::isAxisEnabled | ( | int | axis | ) | const |
Test if an axis is enabled
| axis | Axis, see QwtPlot::Axis |
| void QwtPlotPanner::moveCanvas | ( | int | dx, | |
| int | dy | |||
| ) | [protected, virtual, slot] |
Adjust the enabled axes according to dx/dy
| dx | Pixel offset in x direction | |
| dy | Pixel offset in y direction |
| const QwtPlot * QwtPlotPanner::plot | ( | ) | const |
Return plot widget, containing the observed plot canvas.
| QwtPlot * QwtPlotPanner::plot | ( | ) |
Return plot widget, containing the observed plot canvas.
| void QwtPlotPanner::setAxisEnabled | ( | int | axis, | |
| bool | on | |||
| ) |
En/Disable an axis.
Axes that are enabled will be synchronized to the result of panning. All other axes will remain unchanged.
