Run a program in the background, put it in the system tray

I'm using Qt and I want my program to be able to go in the system tray, but also to be displayed as a window.

For example: I launch my program, it opens a window, ..., I close the window but the program doesn't close, it is still in the background. Then I can reopen the window through the icon created in the system tray.

I know how to create the icon using QSystemTrayIcon and to create a menu when right-clicking on the icon, and launch events through the menu. Yet I don't know how to do so that when I close my program's window, the program remains opened in the background.

To illustrate my point, it would be the same functionment as Steam.

You need to reimplement QWidget::closeEvent, hide the window and ignore the QCloseEvent.

This is explained in detail in the Qt System Tray Icon Example, here is the most interesting part:

void Window::closeEvent(QCloseEvent *event)
{
    if (trayIcon->isVisible()) {
        hide();
        event->ignore();
    }
}
