Guys,

I'm creating specialized plot object in which I would like to know when an plot item has been attached to it.

I've looked around but I can't find a way to do it.

QwtPlotItem is not an QObject, it doesn't emit any signals.
When it's attached to a plot i calls QwtPlot::attachItem(), but this function doesn't do much nor I can overload it.

Any ideas how plot can know when something has been attached to it?

Cheers!
