Member Function Documentation

void QwtPlotItem::attach ( QwtPlot * plot ) [inherited]

Attach the item to a plot.

This method will attach a QwtPlotItem to the QwtPlot argument. It will first detach the QwtPlotItem from any plot from a previous call to attach (if necessary). If a NULL argument is passed, it will detach from any QwtPlot it was attached to.

Parameters:

plot	Plot widget
