no menu Qt 6.8.1 on mac

[Alan Miller]

I compiled Qt 6.8.1 on Mac Mini m2 but I can't get a menubar to display.
This is what I get using this simplified code below.

from PyQt6.QtWidgets import *
from PyQt6.QtGui import *
from PyQt6.QtCore import *

class TestApp(QMainWindow):
    def __init__(self):
        super().__init__()
        self.setupUi()

    def setupUi(self):
        self.setObjectName("MainWindow")
        self.resize(400, 400)
        self.centralwidget = QWidget(self)
        self.centralwidget.setObjectName("centralwidget")
        self.setCentralWidget(self.centralwidget)
        self.grid_layout = QGridLayout()
        self.centralwidget.setLayout(self.grid_layout)

        self.label = QLabel("Test", self.centralwidget)
        self.grid_layout.addWidget(self.label, 0, 0, alignment=Qt.AlignmentFlag.AlignCenter)

        # Create actions
        self.actionAbout_Swing_Studio = QAction("About Swing Studio", self)

        # Create menu bar
        self.menubar = QMenuBar(self)
        self.menubar.setSizePolicy(QSizePolicy.Policy.Expanding, QSizePolicy.Policy.Fixed)
        self.setMenuBar(self.menubar)

        # Create menus
        self.menuSwing_Studio = QMenu("Swing Studio", self.menubar)
        self.menubar.addMenu(self.menuSwing_Studio)

        # Add actions to menus
        self.menuSwing_Studio.addAction(self.actionAbout_Swing_Studio)

        # Create status bar
        self.statusbar = QStatusBar(self)
        self.statusbar.showMessage("Ready")
        self.setStatusBar(self.statusbar)

if __name__ == "__main__":
    import sys
    app = QApplication(sys.argv)
    MainWindow = TestApp()
    MainWindow.show()
    sys.exit(app.exec())

Nevermind, I probably don't understand the widget framework well enough (just started using it)
Anyway I got this to work. Seems I need to

• add actions and menus
• add menus to menubar
• add menubar to toolbar
• add menubar-actions to toolbar
• add toolbar to main window

Hi and welcome to devnet,

macOS does not do menu bar in the window.
Check the bar at the top of the screen where your application name is. You should see what you added there.
You have more information about it in the QMenBar documentation.

@Alan-Miller As @SGaist Wrote menus on MacOS are NOT in the application window, but in the top bar of the OS. Adding a menu to application window like you do now violates the OS design guidelines, but it is of course up to you.

[Alan Miller]

Thanks As @SGaist and @jsulm

.... in the top bar of the OS. ....

Ah, now I get it; I didnt realize what you meant by top bar previously. I thought you meant a "bar" within the Qt.
I see my menus in both places. I'll have to run my code on Win, Linux and I'll clean that up.

@Alan-Miller said in no menu Qt 6.8.1 on mac:

I see my menus in both places

Don't add the menu bar to the toolbar.

[Alan Miller]

Yes, I got that resolved. Just one question., Can I change the application name shown in the top bar?

the script is analyzer.py so the app name shown in my screenshot says "python" and my "About" menu says "About analyzer.py". When I click the "About analyzer.py" I do get my messageBox
