How to hide MaximizeButton of QMainWindow?

[sonichy]

This do not work:

setWindowFlags(windowFlags() &~ Qt::WindowMaximizeButtonHint);

@sonichy

setWindowFlags( Qt::Window | Qt::CustomizeWindowHint | Qt::WindowTitleHint | Qt::WindowSystemMenuHint | Qt::WindowMinimizeButtonHint | Qt::WindowCloseButtonHint );

@raven-worx This can disable maximize button but not hide it !

@sonichy
i think there is no Qt-way to remove the minimize and maximize buttons.
You may want to set the Qt::Tool flag instead the Qt::Window flag:

setWindowFlags( Qt::Tool );

But this also changes the appearance and behavior of the window a bit. But tool-windows do not have minimize and maximize buttons but do also not appear in the taskbar.

@raven-worx setFixedSize is more simple than setWindowFlags, but also disable Maximize button no hide it.

Hi
If Qt::Tool is not what you want, i think disable it is the only options.
It will not be hidden unless a Tool type.

 this helped me:   Form.setMaximumSize(QtCore.QSize(width, height))

class Ui_Form(object):

def setupUi(self, Form):
    
    Form.setObjectName("Form")
    Form.resize(328, 212)
    Form.setMaximumSize(QtCore.QSize(352, 189))
