示例1: removeCurve
void Plot::removeCurve(int index)
{
QwtPlotItem *c = d_curves[index];
if (!c)
return;
if (c->rtti() == QwtPlotItem::Rtti_PlotSpectrogram)
{
Spectrogram *sp = (Spectrogram *)c;
QwtScaleWidget *colorAxis = axisWidget(sp->colorScaleAxis());
if (colorAxis)
colorAxis->setColorBarEnabled(false);
}
c->detach();
QwtPlotItem* p = d_curves.take (index);
// RNT: Making curve_key unique prevents clashes elsewhere
//--curve_key;
// MG: This is a rather crude but effective way of delaying the
// deletion of the curve objects. This is necessary because in
// a tight loop a curve may not have been completely removed
// but the object has been deleted.
Detacher *detacher = new Detacher(p);
detacher->deleteLater();
