menubar Hide/remove

[vinithr]

Hi,

I am trying to remove menubar from form .In form i can able to remove it by right click the form. But when i am running the application its again appears.

I tried the option like SetEnabled,setdisabled,hide,setvisible .

The above options does not help me.

Removing of close,minimize,maximize buttons are also ok for me

Could you please tell me is there any way to do so.


Thanks in advance.
Vinithr

Thanks for your reply. here i have added a sample test program

~MainWindow();

private:

};

#endif // MAINWINDOW_H

// ui->menuBar->setDisabled(1);
// ui->menuBar->setVisible(0);


}

delete ui;
}

Thanks vinithr

You menu bar is empty.
Add a menu item, and it will be visible.

[vinithr]

Thanks.

I need to hide the menubar...

I can't reproduce your problem.
I don't see any menu bar if I remove the menu bar in designer it doesn't get showed in my window.
Here is the generate ui_*.h file as you can see no menu bar is added.
So probably there is not correlation between what you think you do, and what you really do.
Did you remember to save your ui changes?

class Ui_MainWindow
{
public:
    QWidget *centralwidget;
    QStatusBar *statusbar;
    QToolBar *toolBar;
 
    void setupUi(QMainWindow *MainWindow)
    {
        if (MainWindow->objectName().isEmpty())
            MainWindow->setObjectName(QString::fromUtf8("MainWindow"));
        MainWindow->resize(800, 600);
        centralwidget = new QWidget(MainWindow);
        centralwidget->setObjectName(QString::fromUtf8("centralwidget"));
        MainWindow->setCentralWidget(centralwidget);
        statusbar = new QStatusBar(MainWindow);
        statusbar->setObjectName(QString::fromUtf8("statusbar"));
        MainWindow->setStatusBar(statusbar);
        toolBar = new QToolBar(MainWindow);
        toolBar->setObjectName(QString::fromUtf8("toolBar"));
        MainWindow->addToolBar(Qt::TopToolBarArea, toolBar);
 
        retranslateUi(MainWindow);
 
        QMetaObject::connectSlotsByName(MainWindow);
    } // setupUi
 
    void retranslateUi(QMainWindow *MainWindow)
    {
        MainWindow->setWindowTitle(QApplication::translate("MainWindow", "MainWindow", 0, QApplication::UnicodeUTF8));
        toolBar->setWindowTitle(QApplication::translate("MainWindow", "toolBar", 0, QApplication::UnicodeUTF8));
    } // retranslateUi
 
};

class Ui_MainWindow
{
public:
    QWidget *centralwidget;
    QStatusBar *statusbar;
    QToolBar *toolBar;

    void setupUi(QMainWindow *MainWindow)
    {
        if (MainWindow->objectName().isEmpty())
            MainWindow->setObjectName(QString::fromUtf8("MainWindow"));
        MainWindow->resize(800, 600);
        centralwidget = new QWidget(MainWindow);
        centralwidget->setObjectName(QString::fromUtf8("centralwidget"));
        MainWindow->setCentralWidget(centralwidget);
        statusbar = new QStatusBar(MainWindow);
        statusbar->setObjectName(QString::fromUtf8("statusbar"));
        MainWindow->setStatusBar(statusbar);
        toolBar = new QToolBar(MainWindow);
        toolBar->setObjectName(QString::fromUtf8("toolBar"));
        MainWindow->addToolBar(Qt::TopToolBarArea, toolBar);

        retranslateUi(MainWindow);

        QMetaObject::connectSlotsByName(MainWindow);
    } // setupUi

    void retranslateUi(QMainWindow *MainWindow)
    {
        MainWindow->setWindowTitle(QApplication::translate("MainWindow", "MainWindow", 0, QApplication::UnicodeUTF8));
        toolBar->setWindowTitle(QApplication::translate("MainWindow", "toolBar", 0, QApplication::UnicodeUTF8));
    } // retranslateUi

};

In the end this is very poor documented and very easy to accomplish:

Create menu:

// Add help menu
    m_helpMenu = m_mainWindow->menuBar ()->addMenu (Tr ("&Help"));
 
    m_helpMenu->setObjectName ("HelpMenu");
    m_helpMenu->setWindowTitle (Tr ("Help Menu"));
 
    m_helpMenu->addAction (m_userManualAction);
    m_helpMenu->addAction (m_quickStartManualAction);
    m_helpMenu->addAction (m_aboutBoxAction);

// Add help menu
    m_helpMenu = m_mainWindow->menuBar ()->addMenu (Tr ("&Help"));

    m_helpMenu->setObjectName ("HelpMenu");
    m_helpMenu->setWindowTitle (Tr ("Help Menu"));

    m_helpMenu->addAction (m_userManualAction);
    m_helpMenu->addAction (m_quickStartManualAction);
    m_helpMenu->addAction (m_aboutBoxAction);

To copy to clipboard, switch view to plain text mode 

Remove menu without destroy:

m_mainWindow->menuBar ()->removeAction (m_helpMenu->menuAction ());

m_mainWindow->menuBar ()->removeAction (m_helpMenu->menuAction ());
