Getting QMenuBar of child widget to showup

[guilugi]

Your menubar is related to your QMainWindow widget, right ?

What if you add it like this :

mainwindow->setMenuBar(mMenuBar);

mainwindow->setMenuBar(mMenuBar);

To copy to clipboard, switch view to plain text mode 

Or maybe, I misunderstood your issue...

For a main window, menu bar gets created on demand when QMainWindow::menuBar() is called. If you want a separate menu inside the dock widget:

QDockWidget* dockWidget = new QDockWidget(mainWindow);
QWidget* wrapper = new QWidget(dockWidget);
QVBoxLayout* layout = new QVBoxLayout(wrapper);
QMenuBar* menuBar = new QMenuBar(wrapper);
QMenu* dockMenu = menuBar->addMenu("Dock menu");
dockMenu->addAction("blaa");
QTextEdit* textEdit = new QTextEdit(wrapper);
layout->setMenuBar(menuBar);
layout->addWidget(textEdit);
dockWidget->setWidget(wrapper);

QDockWidget* dockWidget = new QDockWidget(mainWindow);
QWidget* wrapper = new QWidget(dockWidget);
QVBoxLayout* layout = new QVBoxLayout(wrapper);
QMenuBar* menuBar = new QMenuBar(wrapper);
QMenu* dockMenu = menuBar->addMenu("Dock menu");
dockMenu->addAction("blaa");
QTextEdit* textEdit = new QTextEdit(wrapper);
layout->setMenuBar(menuBar);
layout->addWidget(textEdit);
dockWidget->setWidget(wrapper);

Thanks for your help, jpn!

This is essentially what I have except my subclass of QWidget is where the layout/menu stuff happens. So I have:

QVBoxLayout* layout = new QVBoxLayout(this);
QMenuBar* menuBar = new QMenuBar(this);

QVBoxLayout* layout = new QVBoxLayout(this);
QMenuBar* menuBar = new QMenuBar(this);

To copy to clipboard, switch view to plain text mode 

Also my widget is created first inside MainWindow, then the dockwidget then I do:

dockwidget->setWidget(wrapper);

dockwidget->setWidget(wrapper);

To copy to clipboard, switch view to plain text mode 

And it doesn't show up. Any clues?

Hmm, make sure that all corresponding steps are done than in the example snippet and that at least one menu/action is added to the menu bar.

I know the menu is setup right, because if I pass 0 as the parent it replaces the menu at the top of the MainWindow.

I think you just got me confused. Oh well, here's another example following more closely to what I think you might have. Hopefully this helps.

Thanks. The problem seemed to be that the dockwidget was not being passed to the constructor of mywidget, but rather, mywidget was later added to the dockwidget. Doing it this way doest embed mywidget ok, but any menus created in the constructor don't show up.
