Hide Minimize and Maximize buttons of the main window - Kubuntu 20.10

stretchthebits

Allo,
I am on Kubuntu 20.10.
I have Qt Creator 4.14.2, it says based on Qt 5.15.2 (GCC 7.3.1 20180303 (Red Hat 7.3.1-5), 64 bit)

WHAT WORKS:
I can disable the Minimize and Maximize buttons.
The window cannot be resized.

THE PROBLEM IS:
I can still see the Minimize and Maximize buttons.

MyProject::MyProject(QWidget *parent, QString &filePath)
	: QMainWindow(parent)
	, ui(new Ui::MyProject)
{

ui->setupUi(this);
setFixedSize(size());

setGeometry(WindowPosition[0], WindowPosition[1], ClientWindowSize[0], ClientWindowSize[1]);
setWindowTitle(ApplicationTitle);
}

That’s not the entire constructor. I cut out most of the fat.

Hi,

You can do some more customization using the WindowFlags.

I added
setWindowFlags(Qt::Dialog | Qt::MSWindowsFixedSizeDialogHint);

but the Maximize button still remains.
The minimize button works and I think that's ok. How can I hide the maximize button?

Did you try playing with the Qt::WindowMinimizeButtonHint/Qt::WindowMaximizeButtonHint/Qt::WindowMinMaxButtonsHint flags? There is a Qt example at https://doc.qt.io/qt-5/qtwidgets-widgets-windowflags-example.html you could play with to see the effects of the various flags.

I found that project in the Qt Creator Welcome screen and I compiled it.
Some of it does stuff, such as a frameless window gives me a frameless window.

Always on top window gives me a Always on top window.

So which one gets rid of the Maximize button?

@stretchthebits
The ones I told you in my previous post. Just as per their names imply.

Note they are "hints". The native windowing system may ignore them.
