mainWindow disable maximize button

Gianluca86

Hi,
I'm trying to disable the maximize button in mainWindow.
I use this line 2:

// main.cpp
int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    MainWindow w;
    w.setWindowFlags(Qt::CustomizeWindowHint | Qt::WindowCloseButtonHint);
    w.showMaximized();
}

In windows it works well (qt 5.7.0 and win 10) while on Ubuntu 14.04 32bit (qt 5.5.1) the maximize button remains active.
is a bug or something wrong with my code?
Thank you

Hallo,
I also didnt found any direct way.. but this lines below in constructor will do the job..!

ui->setupUi(this); // default UI initializer
this->setFixedSize(this->width(),this->height());

I need to be as big as the screen.
Before I used this code to display it as big as the screen

int Height = 0;
int Width = 0;
foreach (QScreen *screen, QGuiApplication::screens()) {
     if(QGuiApplication::primaryScreen()->name() == screen->name())
     {
        QRect rec = screen->availableGeometry();
        Height = rec.height();
        Width = rec.width();
     }
}

w.setFixedSize(Width,Height);

Unfortunately, I do not know why, the height is still longer than the screen. This is why I decided to use showMaximized (), unfortunately this does not seem to go well for both systems.
