QwtPlotOverlay

[carhun]

I would like to clarify about text of QwtPlotPicker... It must be only ONE text, i.e. I can't display for QwtPlotPicker with help of reimplement of trackerTextF() something like: at (pos.x(), pox.y()) - text will be pos.y(), at (pos.x(), pos.y1()) - text will be pos.y1() ? For this I need use separately class QwtText? Am I rigth?

Mb I understand U wrong, but in what archive I need to find about implementation picker as moving vertical line by cursor? I tried to find in examples, there is only bode example use QwtPlotPicker, but not in way that i need...
