Hi,

Which version of Qt ?
On which OS ?
What is the text that is supposed to be shown ?
Please provide a minimal compilable example that shows the issue.

@Pl45m4 Well thank you very much that does the job! Is there any way to make these menu items background heigher without changing the font size.

EDIT:
QMenuBar{
min-height: 20px;
}

Widegts can be added to the MenuBar using the setCornerWidget() function.

So far I have found a solution for myself.

Well, Qt has both a QMenu and a QMenuItem. Only the QMenuItem is supposed to trigger actions. The QMenu itself only has QMenuItems and submenus. So, its action is already defined.

Usually, the QMenuItems have QActions associated with it. For the QMenu::triggered signal the documentation states:

This signal is emitted when an action in this menu is triggered.

To me this reads that you have several entries inside the QMenu and one of these entries triggers an action. This is also why this signal contains the QAction as a parameter. My understanding would mean that clicking on the QMenu itself does not emit a triggered signal, but only clicking on a QMenuItem does.

@Chris-Kawa Thank you for your solutions and suggestions. I made sure to use the overload and to change my code to use the following in the appropriate place:

this->setWindowState(Qt::WindowMaximized);

Thank you again.

@Chris-Kawa, oh, pardon my blindness, it really works. I found that the stylesheet is resetting the width of the button in my case.

@JoeCFD Thank you, will investigate this avenue too!

If this is reproducible with C++, then C++ since the Python bindings are built on top of it.

Thanks. I think you answered the question, please feel free to add anything later if you want. I mark it as solved.

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.

QMenuBar { spacing: 0px; }

That did it! Thank you very much!

Can you provide a more complete code sample ?

This would allow to work on the same base.

Hi SGaist and thank for the help.

For the code being in the constructor when it should not be, I only did it that way to have the simplest code possible to show my issue. I understand and agree with your point. I am working on an already existing application, I created this QtCreator project to isolate and replicate the issue. I do not call QWidget::show() in the constructor of my application.

I have made an important discovery while working on this issue: calling blue_widget->show() at the end of my code in my QtCreator project does fixe the problem, but doing the same in my application does not fix the issue. This is the 1st time I see a different behavior, I thought I had manage to have the same 1:1 behavior between the QtCreator project and my application.

Thanks for the help, I will keep looking.

I helped myself to set a minimum size ->setMinimumSize(300)
I also had to problem that at first pop up, my text was cut off. Nothing of the workarrounds mentioned here helped.

Ok, thanks.

Probably because on OS X the default menu bar is provided by the OS. See QMenuBar's documentation for more details.

However I don't know if it's an OS X specific behavior of Qt Creator.

@pmendl
No problem. Do bear in mind that if you decide to send the event with QApplication::sendEvent, you are responsible for the event object's deletion, so it's a good idea to create it on the stack in that case. Good luck!

Kind regards.

If you mean that you want to follow the guidelines then you have nothing special to do, just use menuBar() and you're good to go.

@Streakflash
Yeah I agree. But a lot of stuff is not really possible from Designer. Sadly.
