QMenuBar minimum size

[Angelo Moriconi]

Hi all !
I've added a QMenuBar inside a QToolBar and I want to set its size policy to constrain the menubar to have the necessary size to visualize all the QMenu without truncate any menu.
With the setSizePolicy I can control the horizontal and vertical policy but I don't know how to retrieve the minimum size (to set in the SizeHint method) that visualize all the items.
Any suggestions ?

Thanks,

Angelo

Does this do what you want?

class MenuBar : public QMenuBar
{
public:
	MenuBar(QWidget* parent = 0)
		: QMenuBar(parent) { }
 
	QSize sizeHint() const
	{
		int ext = style()->pixelMetric(QStyle::PM_ToolBarExtensionExtent);
		return QMenuBar::sizeHint() + QSize(ext, 0);
	}
};
 
MenuBar* menuBar = new MenuBar(toolBar);
menuBar->setSizePolicy(QSizePolicy::Fixed, QSizePolicy::Fixed); // <-- !
menuBar->addMenu(...);
...
toolBar->addWidget(menuBar);

class MenuBar : public QMenuBar
{
public:
	MenuBar(QWidget* parent = 0)
		: QMenuBar(parent) { }

	QSize sizeHint() const
	{
		int ext = style()->pixelMetric(QStyle::PM_ToolBarExtensionExtent);
		return QMenuBar::sizeHint() + QSize(ext, 0);
	}
};

MenuBar* menuBar = new MenuBar(toolBar);
menuBar->setSizePolicy(QSizePolicy::Fixed, QSizePolicy::Fixed); // <-- !
menuBar->addMenu(...);
...
toolBar->addWidget(menuBar);
