How to open MainWindow always on top

JacobNovitsky

If call second time in same application, MainWindow opens in minimized Window, so I need to click its icon on toolbar or alt+tab
I would better explicitly set it to always open on top
please advise

@JacobNovitsky QWidget::showNormal(), QWidget::showMaximized(), QWidget::raise(), QWidget::activateWindow().

Maybe a silly question but
Did you use setWindowFlags(Qt::WindowStaysOnTopHint) ?

#include <QApplication>
#include <QMainWindow>

int main(int argc, char *argv[]) {
    QApplication app(argc, argv);

    QMainWindow mainWindow;
    mainWindow.setWindowTitle("Example Top App");
mainWindow.setWindowFlags(Qt::WindowStaysOnTopHint);

    mainWindow.show();

    return app.exec();
}

If you are on Linux OS, document also says

"Informs the window system that the window should stay on top of all other windows. Note that on some window managers on X11 you also have to pass Qt::X11BypassWindowManagerHint for this flag to work correctly."
