Non-static data member warnings [SOLVED]

[KGWAY]

hello,

I'm running into an abundant amount of non-static warnings for the way I'm setting up my layouts and buttons. The Project still works fine warnings and all.

class Calibration : public QObject
{
    Q_OBJECT
public:
    explicit Calibration(QObject *parent = 0);

public:
    QHBoxLayout *MainLayout = new QHBoxLayout;
    QTableWidget *table = new QTableWidget;
    QHBoxLayout *TableLayout = new QHBoxLayout;
    QVBoxLayout *buttonlayout= new QVBoxLayout;

    QPushButton *CalPA = new QPushButton("Save Cal");
    QPushButton *GetPA = new QPushButton("Get Cal");
    QPushButton *SaveFile = new QPushButton("Save to File");
    QPushButton *GetFile = new QPushButton("Recall File");


private:
    QStringList m2_TableHeader;


signals:

public slots:

};

if I change everything to

 QHBoxLayout *MainLayout;
    QTableWidget *table;
    QHBoxLayout *TableLayout;
    QVBoxLayout *buttonlayout;

    QPushButton *CalPA;
    QPushButton *GetPA;
    QPushButton *SaveFile;
    QPushButton *GetFile ;

this makes the warnings go away but the program crashes. I know the issue is I'm declaring them publicly but I need to use them in a separate class so I don't think I can do so while declaring them privately. Should I be concerned, what should I change to fix this?

Hi,

That's because you're trying to do in-class initialization without C++11 activated. Since you don't seem to use C++11 you must move them in the constructor.

[KGWAY]

If I move them in the constructor they become static and I can't use them in my other class. The issue with that is I declare the buttons public in the header and then lay them out and show them In a separate class constructor(to make the code a little more readable). Would it be in bad taste just to leave it the way it is even if it works? Do you know of a solution where I can declare them in one constructor and use them in a completely different constructor?

[KGWAY]

I solved my issue. Here is the Code:

.h file

public:

    QVBoxLayout *buttonlayout;
    QPushButton *CalPA;
    QPushButton *GetPA;
    QPushButton *SaveFile;
    QPushButton *GetFile;

.ccp file

buttonlayout= new QVBoxLayout;
    CalPA = new QPushButton("Save Cal");
    GetPA = new QPushButton("Get Cal");
    SaveFile = new QPushButton("Save to File");
    GetFile = new QPushButton("Recall File");

Works, no warnings no crashes.

Something sounds fishy: why are you trying to access these members from other widgets ?

[KGWAY]

What I actually wanted was to create and populate a tab in a UI in a separate class. then connect those buttons and what not with code in the MainWindow class. But I actually decided to move most of the initialization back over to the Mainwindow, because of issues with it correctly updating information.

@koahnig double check your settings, the mailing option should be there to configure it.

@SGaist
Apparently landed in the wrong place.
Anyway, I am typically simply checking stuff with the Alarm bell symbol in the top row.
All mailings do not help at all, because for sure I am not checking those or only occassionally at most.

[SGaist]

The notifications bell doesn't seem to always return the data corresponding to the number it shows
