QMenuBar's height has suddenly changed - bug?

[lucadanieli]

I had a QWidget displaying a complex layout containing many widgets.

The code was approximately:

#ifndef Q_OS_MAC
    QMenuBar *newMenu = createMenus();
    outerLayout->addWidget(newMenu);
#endif

QHBoxLayout * h_layout = new QHBoxLayout;
h_layout->setContentsMargins(0,0,0,0);
h_layout->setSpacing(0);
h_layout->addWidget(newDocumentsDocklet);
h_layout->addWidget(newEditorsDocklet);

outerLayout->addLayout(h_layout);
window->setLayout(outerLayout);

This is the result:

Unfortunately, when I changed my h_layout from QHBoxLayout to QSplitter, the QMenuBar changed its height. I don't understand if this is a bug, as I thought the the QMenuBar had a specific height.

The new code looks like this:

#ifndef Q_OS_MAC
    QMenuBar *newMenu = createMenus();
    outerLayout->addWidget(newMenu);
#endif

QSplitter * h_layout = new QSplitter;
h_layout->setOrientation(Qt::Horizontal);
h_layout->addWidget(newDocumentsDocklet);
h_layout->addWidget(newEditorsDocklet);

outerLayout->addWidget(h_layout);
window->setLayout(outerLayout);

This is the new rendering:

Is somebody able to help me understand why this happens?

Hi,

Can you provide a minimal complete sample code that shows that behaviour ?

What version of Qt are you using ? On what Linux distribution ?
