MenuBar issue on macOS

[Raphalaz]

Hi, I'm working on an cross-platform OpenGL app and I have a weird behavior of the menu bar of my QMainWindow on macOS: I can't open the menus by clicking them unless I defocus and refocus the app. The shortcuts are working as intended without the need of defocus/refocus. I'm working with CLion and compiling with CMake. My code is as follow :

window.h:

#ifndef OPENGL_ENGINE_WINDOW_H
#define OPENGL_ENGINE_WINDOW_H

#include <QMainWindow>
#include <QMenuBar>
#include <QMenu>
#include <QAction>

class Window : public QMainWindow {
    Q_OBJECT

public:
    Window();

private:
    void initMenus();
    void loadFile();
    // ...
};

#endif //OPENGL_ENGINE_WINDOW_H

window.cpp:

#include "window.h"

Window::Window() {
    initMenus();
    // ...
    showMaximized();
}

void Window::initMenus() {
    auto *file = menuBar()->addMenu("File");

    auto* loadFile = file->addAction("Open Object File");
    loadFile->setShortcut(QKeySequence("Ctrl+O"));
    connect(loadFile, &QAction::triggered, this, &Window::loadFile);

    file->addSeparator();

    auto* quit = file->addAction("Quit");
    quit->setShortcut(QKeySequence("Ctrl+Q"));
    connect(quit, &QAction::triggered, this, &Window::close);

}

void Window::loadFile() {
    // ...
}

I searched for the issue and it seems to be a known problem on macOS, but all the solutions I found didn't work. Any ideas or something I missed ?

Hi and welcome to devnet,

Are you running macOS 10.15 ?
Which version of Qt ?

[Raphalaz]

Yes, macOS 10.15 and Qt 5.15.1. I tested also on 5.15.0 and 5.14, same behavior.

Then you should check the bug report system. It this issue has not already been reported please consider opening a new report providing a minimal compilable exemple that reproduces the behaviour.
