QMenuBar not responsive

[Daniel_Contro]

Hi to everyone,
I'm developing an application with a custom menubar. I initialize it following the qt documentation but every time that I run my application at the beginning it isn't responsive, I can't interact with the different QMenus. It becomes usable only after I Cmd+Tab to the application. Any idea on what could be causing this? This is my current code regarding the menu:

// in views constructor initialization list:
View(...):
  ...
  _menuBar(new QMenuBar(this)),
  _file(new QMenu(tr("&File"), _menuBar)),
  ... {}

void View::createActions() {
  _newProject = new QAction(tr("&New project"), _file);
  _newProject->setShortcut(QKeySequence::New);
  _newProject->setStatusTip(tr("Create new project"));
  connect(_newProject, SIGNAL(triggered()), this, SLOT(onNewProject()));

  _openProject = new QAction(tr("&Open project"), _file);
  _openProject->setShortcut(QKeySequence::Open);
  _openProject->setStatusTip(tr("Open existing project"));
  connect(_openProject, SIGNAL(triggered()), this, SLOT(onOpenProject()));
...
}

void View::createMenus() {
	createActions();

	_file->addAction(_newProject);
	_file->addAction(_openProject);

	_menuBar->addMenu(_file);
...
}

Hi

Which version of Qt ?
On which OS ?

[Daniel_Contro]

Hi, I'm currently working with Qt 5.9.5 on MacOS 10.15.6

You should try with Qt 5.15.0.

Are you using a QMainWindow ? If so, why not use the menu bar that comes with it ?

[Daniel_Contro]

I'd like to, but it's an university project and I can only use QT 5.9.5. Previously I was using menuBar() but it had the same issue.

It might be an issue with macOS 10.15.

One thing you can do as a workaround is to disable the native macOS menu bar. You will have it on the QMainWindow but it should be usable.
