\class QGuiApplication
\brief The QGuiApplication class manages the GUI application's control
flow and main settings.
\inmodule QtGui
\since 5.0
QGuiApplication contains the main event loop, where all events from the window
system and other sources are processed and dispatched. It also handles the
application's initialization and finalization, and provides session management.
In addition, QGuiApplication handles most of the system-wide and application-wide
settings.
For any GUI application using Qt, there is precisely \b one QGuiApplication
object no matter whether the application has 0, 1, 2 or more windows at
any given time. For non-GUI Qt applications, use QCoreApplication instead,
as it does not depend on the \l QtGui library. For QWidget based Qt applications,
use QApplication instead, as it provides some functionality needed for creating
QWidget instances.
The QGuiApplication object is accessible through the instance() function, which
returns a pointer equivalent to the global \l qApp pointer.
QGuiApplication's main areas of responsibility are:
\list
\li It initializes the application with the user's desktop settings,
such as palette(), font() and styleHints(). It keeps
track of these properties in case the user changes the desktop
globally, for example, through some kind of control panel.
\li It performs event handling, meaning that it receives events
from the underlying window system and dispatches them to the
relevant widgets. You can send your own events to windows by
using sendEvent() and postEvent().
\li It parses common command line arguments and sets its internal
state accordingly. See the \l{QGuiApplication::QGuiApplication()}
{constructor documentation} below for more details.
\li It provides localization of strings that are visible to the
user via translate().
\li It provides some magical objects like the clipboard().
\li It knows about the application's windows. You can ask which
window is at a certain position using topLevelAt(), get a list of
topLevelWindows(), etc.
\li It manages the application's mouse cursor handling, see
setOverrideCursor()
\li It provides support for sophisticated \l{Session Management}
{session management}. This makes it possible for applications
to terminate gracefully when the user logs out, to cancel a
shutdown process if termination isn't possible and even to
preserve the entire application's state for a future session.
See isSessionRestored(), sessionId() and commitDataRequest() and
saveStateRequest() for details.
\endlist
Since the QGuiApplication object does so much initialization, it \e{must} be
created before any other objects related to the user interface are created.
QGuiApplication also deals with common command line arguments. Hence, it is
usually a good idea to create it \e before any interpretation or
modification of \c argv is done in the application itself.

2645 -
2646 Sets the application override cursor to \a cursor. -
2647 -
2648 Application override cursors are intended for showing the user that the -
2649 application is in a special state, for example during an operation that -
2650 might take some time. -
2651 -
2652 This cursor will be displayed in all the application's widgets until -
2653 restoreOverrideCursor() or another setOverrideCursor() is called. -
2654 -
2655 Application cursors are stored on an internal stack. setOverrideCursor() -
2656 pushes the cursor onto the stack, and restoreOverrideCursor() pops the -
2657 active cursor off the stack. changeOverrideCursor() changes the curently -
2658 active application override cursor. -
2659 -
2660 Every setOverrideCursor() must eventually be followed by a corresponding -
2661 restoreOverrideCursor(), otherwise the stack will never be emptied. -
