@Gojir4 @Chrisw01
where should I add this line exectly?
setWindowsFlags(Qt::WindowCloseButtonHint, false);#include "mainwindow.h" #include "ui_mainwindow.h" MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent), ui(new Ui::MainWindow) { ui->setupUi(this); } MainWindow::~MainWindow() { delete ui; } void MainWindow::on_pushButton_clicked() { ui->textEdit->setText("this is for test"); }
@Mijaz Please read again what @Gojir4 wrote:
"Add setWindowsFlags(Qt::WindowCloseButtonHint, false); in your widget's constructor"https://doc.qt.io/qt-5/qtwidgets-widgets-windowflags-example.html

Hi,
I am using qt4.8.7.
your suggested command not working.#include "mainwindow.h" #include "ui_mainwindow.h" #include <QDebug> MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent), ui(new Ui::MainWindow) { ui->setupUi(this); setWindowFlags(Qt::WindowCloseButtonHint, false); timerId = startTimer(1000); } MainWindow::~MainWindow() { killTimer(timerId); delete ui; } void MainWindow::timerEvent(QTimerEvent *event) { qDebug() << "Update..."; ui->lineEdit->setText("test "); }

Important information, that one should state in the opening post.
besides that, looking into the Qt4 Documentation shows the following:
https://doc.qt.io/archives/qt-4.8/qwidget.html#windowFlags-prop
with an actual example on how top use it:
https://doc.qt.io/archives/qt-4.8/qt-widgets-windowflags-example.html->
setWindowFlags(windowFlags() & ~Qt::WindowCloseButtonHint); -
MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent), ui(new Ui::MainWindow) { ui->setupUi(this); setWindowsFlags(Qt::WindowCloseButtonHint, false); } -
@Gojir4
Now this is working{ ui->setupUi(this); timerId = startTimer(1000); this->setWindowFlags(Qt::WindowMaximizeButtonHint); }
@Mijaz great
just a warning, since you're on linux. Not every WindowManager will support the individual showing/hiding of Window-Buttons

Q: What's that?
A: It's blue light.
Q: What does it do?
A: It turns blue. -

Keep in mind that this way you disable all other flags. But as long as this is fine for you you can do it this way.

@J-Hilk
yes, When I deploy it to the board then it still showing the close mark.How I can remove this permanently?
@Mijaz change the window manager on the board...
Here a guide, on how to do it on GNOME, should be similar for all Linux flavors
