    Hi GrahamL,

    I just succeeded adding 2 project together. but I can't take info from other project. Take a look at this.

    double freq = StatusWindow::AngularVelocities.gimbalNS1Vel;

    C:\Users\Zhihao\Documents\SourceTree Repos\qtlearning\NISimpleTest - Zhihao Version\stepperwindow.cpp:122: error: expected primary-expression before '.' token
    double freq = StatusWindow::AngularVelocities.gimbalNS1Vel;

    I am not that experience either. Would be real nice if you can help me out.

    Greetings,

    Zhihao

    In stepperwindow.cpp , did you include the .H file where StatusWindow lives ?

      @mrjj Yes, I did. When I start typing Qt shows me the available namespace and instants.

        Ok?!
        if you place cursor on AngularVelocities and press F2, it can go to the definition ?

          Depending on where the files are located, you might need to add paths to the .PRO file

          like
          INCLUDEPATH += ../../Common/CONET
          ../../Common/Exception
          ../../Common/FileStream
          ../../Common/HAL

          HEADERS += AppStyle.h
          ../../Common/Types/AbstractTypes.h
          ../../Common/Types/PedaxTypes.h
          ../../Common/Types/Variant.h
          ../../Common/XML/pugixml-1.5/src/pugiconfig.hpp
          ../../Common/XML/pugixml-1.5/src/pugixml.hpp

            This is a part of the header file:

            class StatusWindow : public QMainWindow {
            Q_OBJECT

            public:
            explicit StatusWindow(QWidget *parent = 0);
            ~StatusWindow();
            SolTrack soltrack;
            SolTrack::Position oldPosition;

            typedef struct {
              double hhRefVel, decRefVel;
              double azVel, altRefVel;
              double gimbalNS1Vel,gimbalNS2Vel, gimbalEW1Vel,gimbalEW2Vel;
            } AngularVelocities;
            

            AngularVelocities angVels;

            private:
            Ui::StatusWindow *ui;

            void updateStatusScreen();
            void computeAngularVelocities(SolTrack::Position sunPos, SolTrack::Position oldPos, AngularVelocities* angVels);

            private slots:
            void updateStatusScreenCurrent();
            void on_actionAbout_Qt_triggered();
            void on_actionAbout_SolTraQ_triggered();
            void on_actionClose_triggered();
            void on_actionHelp_triggered();
            };

            I need to get the data from the gimbals

              ahh I see
              when you say
              double freq = StatusWindow::AngularVelocities.gimbalNS1Vel;
              you try to access AngularVelocities as it was a static struct.
              But its not - so you need an instance of StatusWindow for it to work.

              like

              StatusWindow *MyInst = new StatusWindow ();
              double freq =MyInst->AngularVelocities.gimbalNS1Vel;
              delete MyInst ;
              

              So if StatusWindow was the mainwindow in the other project, then you
              might not have an instance in the "this" project and you would need to create one.

              Have you considered to move the data to its own file so its easier to use both places ?

                @mrjj That is a good, but I had the idea of just taking it from another directory. So whenever i update the other files, I will not have to copy and paste it over here again.

                  Well if you need both projects still working then
                  moving the data our from mainwindow to its own file would make it far easier.
                  Copy/pasting code often comes back and bite. :)

                        one note:

                        I suspect you need to call
                        void computeAngularVelocities(SolTrack::Position sunPos, SolTrack::Position oldPos, AngularVelocities* angVels);

                        for angVels to have anything but zero.

                              I am trying to add new features to a GUI. The files for new features such as camera output, video output etc exists on a different location.

                              What would be the best way to do agile Qt development.

                                Well agile is not different with Qt.
                                Just make sure project is under code revision control and go ahead :)
