585 \class QCoreApplication -

586 \inmodule QtCore -

587 \brief The QCoreApplication class provides an event loop for Qt -

588 applications without UI. -

589 -

590 This class is used by non-GUI applications to provide their event -

591 loop. For non-GUI application that uses Qt, there should be exactly -

592 one QCoreApplication object. For GUI applications, see -

593 QGuiApplication. For applications that use the Qt Widgets module, -

594 see QApplication. -

595 -

596 QCoreApplication contains the main event loop, where all events -

597 from the operating system (e.g., timer and network events) and -

598 other sources are processed and dispatched. It also handles the -

599 application's initialization and finalization, as well as -

600 system-wide and application-wide settings. -

601 -

602 \section1 The Event Loop and Event Handling -

603 -

604 The event loop is started with a call to exec(). Long-running -

605 operations can call processEvents() to keep the application -

606 responsive. -

607 -

608 In general, we recommend that you create a QCoreApplication, -

609 QGuiApplication or a QApplication object in your \c main() -

610 function as early as possible. exec() will not return until -

611 the event loop exits; e.g., when quit() is called. -

612 -

613 Several static convenience functions are also provided. The -

614 QCoreApplication object is available from instance(). Events can -

615 be sent or posted using sendEvent(), postEvent(), and -

616 sendPostedEvents(). Pending events can be removed with -

617 removePostedEvents() or flushed with flush(). -

618 -

619 The class provides a quit() slot and an aboutToQuit() signal. -

620 -

621 \section1 Application and Library Paths -

622 -

623 An application has an applicationDirPath() and an -

624 applicationFilePath(). Library paths (see QLibrary) can be retrieved -

625 with libraryPaths() and manipulated by setLibraryPaths(), addLibraryPath(), -

626 and removeLibraryPath(). -

627 -

628 \section1 Internationalization and Translations -

629 -

630 Translation files can be added or removed -

631 using installTranslator() and removeTranslator(). Application -

632 strings can be translated using translate(). The QObject::tr() -

633 and QObject::trUtf8() functions are implemented in terms of -

634 translate(). -

635 -

636 \section1 Accessing Command Line Arguments -

637 -

638 The command line arguments which are passed to QCoreApplication's -

639 constructor should be accessed using the arguments() function. -

640 -

641 \note QCoreApplication removes option \c -qmljsdebugger="...". It parses the -

642 argument of \c qmljsdebugger, and then removes this option plus its argument. -

643 -

644 For more advanced command line option handling, create a QCommandLineParser. -

645 -

646 \section1 Locale Settings -

647 -

648 On Unix/Linux Qt is configured to use the system locale settings by -

649 default. This can cause a conflict when using POSIX functions, for -

650 instance, when converting between data types such as floats and -

651 strings, since the notation may differ between locales. To get -

652 around this problem, call the POSIX function \c{setlocale(LC_NUMERIC,"C")} -

653 right after initializing QApplication, QGuiApplication or QCoreApplication -

654 to reset the locale that is used for number formatting to "C"-locale. -

991 /*! -

992 Sends \a event to \a receiver: \a {receiver}->event(\a event). -

993 Returns the value that is returned from the receiver's event -

994 handler. Note that this function is called for all events sent to -

995 any object in any thread. -

996 -

997 For certain types of events (e.g. mouse and key events), -

998 the event will be propagated to the receiver's parent and so on up to -

999 the top-level object if the receiver is not interested in the event -

1000 (i.e., it returns \c false). -

1001 -

1002 There are five different ways that events can be processed; -

1003 reimplementing this virtual function is just one of them. All five -

1004 approaches are listed below: -

1005 \list 1 -

1006 \li Reimplementing \l {QWidget::}{paintEvent()}, \l {QWidget::}{mousePressEvent()} and so -

1007 on. This is the most common, easiest, and least powerful way. -

1008 -

1009 \li Reimplementing this function. This is very powerful, providing -

1010 complete control; but only one subclass can be active at a time. -

1011 -

1012 \li Installing an event filter on QCoreApplication::instance(). Such -

1013 an event filter is able to process all events for all widgets, so -

1014 it's just as powerful as reimplementing notify(); furthermore, it's -

1015 possible to have more than one application-global event filter. -

1016 Global event filters even see mouse events for -

1017 \l{QWidget::isEnabled()}{disabled widgets}. Note that application -

1018 event filters are only called for objects that live in the main -

1019 thread. -

1020 -

1021 \li Reimplementing QObject::event() (as QWidget does). If you do -

1022 this you get Tab key presses, and you get to see the events before -

1023 any widget-specific event filters. -

1024 -

1025 \li Installing an event filter on the object. Such an event filter gets all -

1026 the events, including Tab and Shift+Tab key press events, as long as they -

1027 do not change the focus widget. -

1028 \endlist -

1029 -

1030 \b{Future direction:} This function will not be called for objects that live -

1031 outside the main thread in Qt 6. Applications that need that functionality -

1032 should find other solutions for their event inspection needs in the meantime. -

1033 The change may be extended to the main thread, causing this function to be -

1034 deprecated. -

1035 -

1036 \warning If you override this function, you must ensure all threads that -

1037 process events stop doing so before your application object begins -

1038 destruction. This includes threads started by other libraries that you may be -

1039 using, but does not apply to Qt's own threads. -

1217 Enters the main event loop and waits until exit() is called. Returns -

1218 the value that was passed to exit() (which is 0 if exit() is called via -

1219 quit()). -

1220 -

1221 It is necessary to call this function to start event handling. The -

1222 main event loop receives events from the window system and -

1223 dispatches these to the application widgets. -

1224 -

1225 To make your application perform idle processing (by executing a -

1226 special function whenever there are no pending events), use a -

1227 QTimer with 0 timeout. More advanced idle processing schemes can -

1228 be achieved using processEvents(). -

1229 -

1230 We recommend that you connect clean-up code to the -

1231 \l{QCoreApplication::}{aboutToQuit()} signal, instead of putting it in -

1232 your application's \c{main()} function because on some platforms the -

1233 exec() call may not return. For example, on Windows -

1234 when the user logs off, the system terminates the process after Qt -

1235 closes all top-level windows. Hence, there is no guarantee that the -

1236 application will have time to exit its event loop and execute code at -

1237 the end of the \c{main()} function after the exec() -

1238 call. -

2777 Adds a global routine that will be called from the QCoreApplication -

2778 destructor. This function is normally used to add cleanup routines -

2779 for program-wide functionality. -

2780 -

2781 The cleanup routines are called in the reverse order of their addition. -

2787 -

2788 Note that for an application- or module-wide cleanup, qaddPostRoutine() -

2789 is often not suitable. For example, if the program is split into dynamically -

2790 loaded modules, the relevant module may be unloaded long before the -

2791 QCoreApplication destructor is called. In such cases, if using qaddPostRoutine() -

2792 is still desirable, qRemovePostRoutine() can be used to prevent a routine -

2793 from being called by the QCoreApplication destructor. For example, if that -

2794 routine was called before the module was unloaded. -

2795 -

2796 For modules and libraries, using a reference-counted -

2797 initialization manager or Qt's parent-child deletion mechanism may -

2798 be better. Here is an example of a private class that uses the -

2799 parent-child mechanism to call a cleanup function at the right -

2800 time: -

2801 -

2802 \snippet code/src_corelib_kernel_qcoreapplication.cpp 5 -
