    Default How to change the menubar after log in as super user.

    Hello, I am writing an app which after the main window shows it has a menubar with the option to connect, with a "super" user which has some adittional menus/actions.
    The thing is that I have different classes for different menubars and another class for creating the dialog.
    The issue is that I cannot figure it out how to actually change the menubar.
    Here is the main window header file:
    Qt Code: 
    1. #ifndef CAMER_H
    2. #define CAMER_H
    3.  
    4. #include <QMainWindow>
    5. #include <QSettings>
    6. #include <QDialog>
    7. #include <QDialogButtonBox>
    8. #include <QLabel>
    9. #include <QLineEdit>
    10. #include <QGridLayout>
    11. #include <QPushButton>
    12. namespace Ui {
    13. class camer;
    14. }
    15.  
    16. class camer : public QMainWindow
    17. {
    18.     Q_OBJECT
    19.  
    20. public:
    21.     explicit camer(QWidget *parent = 0);
    22.     ~camer();
    23.     void setMeniuAdmin();
    24.     void setMeniuNeaut();
    25. private:
    26.     Ui::camer *ui;    
    27. private slots:
    28.     void creareDialogConect();
    29. public slots:    
    30. };
    31.  
    32. #endif // CAMER_H
    To copy to clipboard, switch view to plain text mode 

    here is the main window cpp file:
    Qt Code: 
    1. #include "camer.h"
    2. #include "conn.h"
    3. #include "FerDialConect.h"
    4. #include "meniuNeautentificat.h"
    5. #include "meniuAdmin.h"
    6. camer::camer(QWidget *parent):QMainWindow(parent){
    7.     setMinimumSize(800,600);
    8.     setMeniuNeaut();
    9. }
    10.  
    11. camer::~camer()
    12. {
    13.     //settings saving function goes here
    14. }
    15.  
    16.  
    17. void camer::creareDialogConect(){
    18.     FerDialConect *fdc=new FerDialConect(this);
    19.     fdc->afisDial();
    20. }
    21.  
    22. void camer::setMeniuNeaut(){
    23.     menNeaut *mn=new menNeaut(this);
    24.     setMenuBar(mn);
    25. }
    26.  
    27. void camer::setMeniuAdmin(){
    28.     MeniuAdmin *mad=new MeniuAdmin(this);
    29.     setMenuBar(mad);
    30. }

    here are the dialog header and cpp files:
    Qt Code: 
    1. #ifndef FERDIALCONECT_H
    2. #define FERDIALCONECT_H
    3. #include <QDialog>

    5. #include <QLabel>
    6. #include <QLineEdit>
    7. #include <QDialogButtonBox>
    8. #include <QMessageBox>
    9. #include <QPushButton>
    10. #include "camer.h"
    11. class FerDialConect:public camer{
    12.     Q_OBJECT
    13. public:
    14.     explicit FerDialConect(camer *parent = 0);
    15.     void afisDial();
    16.     QString util,parola;
    17. private:    
    18.     QGridLayout *amplasareDialCon,*amplasareDialCon1,*amplasareDialCon2;
    19.     QLabel *etUtil,*etPar;
    20.     QLineEdit *txtUtil,*txtPar;
    21.     QPushButton *bCon,*bAnul;
    22.     QDialogButtonBox *cutieButCon;
    23.     QDialog *dialogConect;
    24. private slots:
    25.     void con();
    26. };

    Qt Code: 
    1. #include "FerDialConect.h"

    4. FerDialConect::FerDialConect(camer *parent):camer(parent){

    14.     cutieButCon=new QDialogButtonBox;
    15.     cutieButCon->setOrientation(Qt::Horizontal);
    16.     bCon=new QPushButton(tr("Conectare"));
    17.     bAnul=new QPushButton(tr("Anulare"));
    18.     cutieButCon->addButton(bCon,QDialogButtonBox::AcceptRole);
    19.     cutieButCon->addButton(bAnul,QDialogButtonBox::RejectRole);
    20.     connect(cutieButCon,SIGNAL(rejected()),dialogConect,SLOT(reject()));
    21.     connect(cutieButCon,SIGNAL(accepted()),this,SLOT(con()));
    22.     amplasareDialCon->addLayout(amplasareDialCon1,0,0);
    23.     amplasareDialCon->addLayout(amplasareDialCon2,1,0);

    34.     dialogConect->exec();
    35. }

    59.  
    60.     }
    61. }
    To copy to clipboard, switch view to plain text mode 

    here is the default menubar files:
    Qt Code: 
    1. #ifndef MENIUNEAUTENTIFICAT_H
    2. #define MENIUNEAUTENTIFICAT_H
    3. #include <QMenuBar>
    4. #include <QMenu>
    5. #include <QAction>
    6. #include "camer.h"
    7.  
    8. class menNeaut:public QMenuBar{
    9.     Q_OBJECT
    10. public:
    11.     explicit menNeaut(camer *parent=0);
    12. private:
    13.     QMenu *meniuStandard;
    14.     QAction *conectare,*inchideApp;
    15. private slots:
    16. };
    17.  
    18. #endif // MENIUNEAUTENTIFICAT_H
    To copy to clipboard, switch view to plain text mode 

    Qt Code: 
    1. #include "meniuNeautentificat.h"
    2. menNeaut::menNeaut(camer *parent):QMenuBar(parent){
    3.     meniuStandard=new QMenu("Meniu");
    4.     conectare=new QAction(tr("Conectare"),this);
    5.     connect(conectare,SIGNAL(triggered()),parent,SLOT(creareDialogConect()));
    6.     inchideApp=new QAction(tr("Inchide"),this);
    7.     connect(inchideApp,SIGNAL(triggered()),parent,SLOT(inchideApplicatie()));
    8.     meniuStandard->addAction(conectare);
    9.     meniuStandard->addAction(inchideApp);
    10.     addMenu(meniuStandard);
    11. }
    To copy to clipboard, switch view to plain text mode 

    here are the files for the second menu(its just a basic setup):
    Qt Code: 
    1. #ifndef MENIUADMIN_H
    2. #define MENIUADMIN_H
    3. #include <QMenuBar>
    4. #include "camer.h"
    5. #include <QMenu>
    6. #include <QAction>
    7.  
    8. class MeniuAdmin:public QMenuBar{
    9.     Q_OBJECT
    10. public:
    11.     explicit MeniuAdmin(camer *parent=0);
    12. private:
    13.     QMenu *meniu;
    14.     QAction *dateP;
    15. private slots:
    16. };
    17.  
    18. #endif // MENIUADMIN_H
    To copy to clipboard, switch view to plain text mode 

    Qt Code: 
    1. #include "meniuAdmin.h"
    2. MeniuAdmin::MeniuAdmin(camer *parent):QMenuBar(parent){
    3.     meniu=new QMenu(tr("Meniu"),this);
    4.     dateP=new QAction(tr("Date Personale"),this);
    5.     meniu->addAction(dateP);
    6.     addMenu(meniu);
    7. }
