72 \brief The QSplashScreen widget provides a splash screen that can
73 be shown during application startup.
74
75 \ingroup misc
76 \mainclass
77
78 A splash screen is a widget that is usually displayed when an
79 application is being started. Splash screens are often used for
80 applications that have long start up times (e.g. database or
81 networking applications that take time to establish connections) to
82 provide the user with feedback that the application is loading.
83
84 The splash screen appears in the center of the screen. It may be
85 useful to add the Qt::WindowStaysOnTopHint to the splash widget's
86 window flags if you want to keep it above all the other windows on
87 the desktop.
