How to hide/remove a addMenu() menu

Hi,

I've added a menu and menu items using menuBar()->addMenu() and the subsequent addAction() calls. I know that calling clear() will remove the menu subitems added by addAction(), but how do I remove or hide the actual menu
item that was added by the addMenu() call.

I don't see any reference to this functionality.

Thanks!

Mark

RE: How to hide/remove a addMenu() menu

MrGarbage,

Below, if you double click on File 1 menu, it hides/shows File 2 menu.

Source code

#include <QApplication>
#include <QWidget>
#include <QVBoxLayout>
#include <QMenuBar>
#include <QMenu>

int main( int argc, char **argv )
{
    QApplication app( argc, argv );

    QWidget *widget = new QWidget();
    QVBoxLayout *layout = new QVBoxLayout( widget );

    QMenuBar *menuBar = new QMenuBar();
    QMenu *menu = new QMenu( "File 1" );
    menu->menuAction()->setCheckable( true );
    QMenu *menu2 = new QMenu( "File 2" );
    menuBar->addMenu( menu );
    menuBar->addMenu( menu2 );

    QObject::connect( menu->menuAction(), SIGNAL( toggled( bool ) ),
            menu2->menuAction(), SLOT( setVisible( bool ) ) );

    layout->addWidget( menuBar );
    widget->show();

    return app.exec();
}

Hope this helps....

Hi Mark,

Here is another solution:

If you're using Designer:

Source code

//copy the existing menu items
	QMenu *menuFile = ui.menuFile;
	QMenu *menuEdit = ui.menuEdit;
	QMenu *menuHelp = ui.menuHelp;

	ui.menubar->clear();

	//replace the menu items
	ui.menubar->addMenu(menuFile);
	ui.menubar->addMenu(menuHelp);

I found no method to hide the menus off the menu bar.

or also you can use somthing like this:

	Source code
1	ui.menuHelp->menuAction()->setVisible(false);
