[SOLVED]Need help with combining GUI

zhihaowu

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

mrjj

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

mrjj

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

mrjj

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 ?

zhihaowu

@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.

mrjj

@zhihaowu
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. :)

@mrjj

C:\Users\Zhihao\Documents\SourceTree Repos\qtlearning\NISimpleTest - Zhihao Version\stepperwindow.cpp:126: error: invalid use of 'StatusWindow::AngularVelocities'
double freq = MyInst->AngularVelocities.gimbalNS1Vel;
^

@zhihaowu said:

Hi that's the type definition.
sorry my bad
it should be angVels;

double freq = MyInst->angVels.gimbalNS1Vel;

mrjj

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.

zhihaowu

@mrjj It is working!!! Super thanks mate.

mrjj

@zhihaowu

\o/
Super

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.

With best regards,

Karan

mrjj

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