    program not seeing arguments

    normally I use

    ./QtFigs4 figs.xml

    for execution... but where do I specify figs.xml

    I looked all over

    I even put the following:

    ./QtFigs4 /home/qt4user/QtFigs4/figs.xml

    in GDB startup script under gdb option

    This program has been running 11 years.

    It is an excellent intro to SAX, paintEvent and collections.

      Usually the arguments are passed to your application through various layers of your operation system. How do you access them in your software? What happens if you do something like that:

      @
      int main(int argc, char** argv)
      {
      qDebug() << argv[1] << endl; // might crash if there's no command line argument...
      ...
      }
      @

        [Edit: this doesn't really apply to the problem. See below.]

        Shouldn't crash:

        @
        #include <QDebug>

        int main(int argc, char** argv)
        {
        qDebug() << "Application name: " << argv[0];
        if (argc) {
        for (int idx = 1; idx < argc; idx++)
        qDebug() << "Arg" << idx << "is" << argv[idx];
        } else {
        qDebug() << "No arguments given.";
        }
        return 0;
        }
        @

          normally I execute the program using

          ./QtFigs4 figs.xml

          ...OR...
          ./QtFigs4 /home/qt4user/QtFigs4/figs.xml

          I just installed Qt sdk and to get going I opened

          the program by pointing to QtFigs4.pro

          Only problem now is the argument..a file name figs.xml

          Almost all SDKs allow entry of command line argument(s)

            Ah.... misunderstood your question, I think!

            In Creator, go to the "Projects" icon on the left-hand panel, select "Run Settings" from the toolbar at the top of the screen. Then fill in the "Arguments:" field.

                Ok, under Targets, there will be one or more platform descriptions (Desktop, Qt Simulator, Symbian Device, etc.) Each of those will have a (Build | Run) button group. Select "Run" on the platform you're interested in.

                (See "here":http://doc.qt.nokia.com/qtcreator-2.4/images/qtcreator-projectpane.png for illustration.)

                Description of run settings are "here.":http://doc.qt.nokia.com/qtcreator-2.4/creator-run-settings.html

                  thanks! It works except for a nasty little messagebox that says:

                  "debugger settings point to a script file
                  /home/qt4user/QtFigs4/figs.xml

                  which is not accessible!

                  I even did a chmod 777 on it just to try to remove the #$%^ message

                  I'll have to track that down!"

                    got rid of the nasty message box...things runs now

                    THANKS!

                    Next I'll try an eclipse project I know works.

                    It is a great little lottery program with a histogram of

                    value occurences . WOW it works and I don't have to open another window

                    for the ui

                      EEEHA! two of my eclipse projects with UI are working.

                      Saw the build/run thing...but

                      but...nothing happened when I selected either build or run

                      The message box was not a crash exactly but a complaint!

                      Eclipse wasted a lot of my time. Qt advice says NOT to use the eclipse

                      that comes with various distros.

                      I love QT SDK

                        Qt examples are usually overly complex.

                        The 3 examples I've just got running are superb mentoring examples.

                        I can email to anybody!

                        Qt should be avail to get/update under Fedora yum

                        as easy as

                        yum install qtsdk
