#81 How to read point coordinate in a QwtPlot at mouse click

[Marco Montecchi]

I am using qwt to draw plots for the scientific software kSEMAW also host on source forge. More precisely I am converting the FORTRAN parts of the actual version in C++. The GUI is made by Qt.
Till now all was running smoothly, bu now I need to activate the reading of the point coordinates x,y over a QwtPlot. I am a Physicist; I am self-taught about information technology I carefully read the qwt documentation. I understood that what I need is possible in qwt, but I am not able to set the reading by the cursor. Neither I found simple examples in the web. Could someone help me? I believe it could be possible by adding few rows of code during the setting of the QwtPlot of interest.
Many Thanks
