c++ - Non interactive items in QMenu

Question

I'm trying to build a menu with some items that are not interactive in QT. I subclass QMenu in my MyCustomMenuClass. I'm trying to add section titles to my menu so that it's clearer for the user.

For example, it should look like this:

My section 1 title
Action 1
Action 2
Action 3
My second section title
Action 4
Action 5

The issue is that the section titles always react to the mouse, but I would like them to not react to a mouse over so that it would be prettier. Any idea on how to do it?

From the QMenu documentation:

There are four kinds of action items: separators, actions that show a submenu, widgets, and actions that perform an action. Separators are inserted with addSeparator(), submenus with addMenu(), and all other items are considered action items.

This rings a bell: Widgets! You can add a widget to the menu? That means you are settled, you can do whatever you want.

What you need is a QWidgetAction object. It allows you to insert a custom widget as an action. Your titles will be custom widgets. If you only need a title, a QLabel should suffice:

QMenu* myMenu = new QMenu(...);
QLabel* label = new QLabel(tr("<b>Title</b>"), this);
label->setAlignment(Qt::AlignCenter);

QWidgetAction* a = new QWidgetAction(myMenu);
a->setDefaultWidget(label);
