    Hi

    Windows 7
    Qt 5.3.0 mingw

    I use the following code to show tray icon, but it stays there even after I close my application, they clear only when I hover over them, what wrong am I doing?

    @
    QSystemTrayIcon *icon = new QSystemTrayIcon(QIcon(":/icons/logo.png"));
    if(icon->isSystemTrayAvailable()){
    icon->show();
    icon->showMessage(tr("Help"), tr("Help text"), QSystemTrayIcon::Information, 2000);
    }
    @

      Hi,

      Since you did not give a parent to your QSystemTrayIcon, are you deleting it somewhere ?

        Thanks for the quick response SGaist!

        No, should I use (this) as parent?

        @
        QSystemTrayIcon *icon = new QSystemTrayIcon(QIcon(":/icons/logo.png"), this);
        @
        I am creating the icon in the main class of type (MainWindow).

        PS: I have posted the same by mistake in other forum (Cloud), I could not deleted it, sorry.

          Indeed you should. Without that you have a memory leak and icon will not be properly destroyed when your program ends

              Since it's now all working fine, please update the thread title prepending [solved] so other forum users may know a solution has been found :)
