3rd Party Software

Hi, I'm not an expert in this thing, but I think you should use "QNmeaPositionInfoSource":http://doc.qt.nokia.com/qtmobility-1.1.0-beta/qnmeapositioninfosource.html and use, as QIODevice, "QExtSerialPort":http://qextserialport.sourceforge.net/ Once I wrote a GPS application, but I parsed NMEA sentences by myself, cause at that time there was no QtMobility. QExtSerialPort works fine, as long as your GPS is seen on your desktop as a COM device (virtual or not). Tony.

Thank you. This was also my first intention but I was not sure that it is the "Qt way" of doing things so your answers are very valuable feedback for me.

@kalle I'm looking for a plotting library that can plot data interactively. Specifically, I wish to render 1D histogram like curves that are spline smoothed, allow overlay with seperate axes on the left and right. The plots need to be rendered as "filled" plots (i.e. color under the curve), but the fill area needs to be controllable by user interaction. Automatic scaling, labeling, legending, and coloring would also be nice. The qwt library almost delivers what I need. However, I find its interface non-intuitive and its 2D plot rendering leaves a lot of features out. I looked at KD Chart, and it may be what I am looking for. Of course, I'm only interested in free, open-source solutions.
