364 \class QGuiApplication -

365 \brief The QGuiApplication class manages the GUI application's control -

366 flow and main settings. -

367 -

368 \inmodule QtGui -

369 \since 5.0 -

370 -

371 QGuiApplication contains the main event loop, where all events from the window -

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

373 application's initialization and finalization, and provides session management. -

374 In addition, QGuiApplication handles most of the system-wide and application-wide -

375 settings. -

376 -

377 For any GUI application using Qt, there is precisely \b one QGuiApplication -

378 object no matter whether the application has 0, 1, 2 or more windows at -

379 any given time. For non-GUI Qt applications, use QCoreApplication instead, -

380 as it does not depend on the Qt GUI module. For QWidget based Qt applications, -

381 use QApplication instead, as it provides some functionality needed for creating -

382 QWidget instances. -

383 -

384 The QGuiApplication object is accessible through the instance() function, which -

385 returns a pointer equivalent to the global \l qApp pointer. -

386 -

387 QGuiApplication's main areas of responsibility are: -

388 \list -

389 \li It initializes the application with the user's desktop settings, -

390 such as palette(), font() and styleHints(). It keeps -

391 track of these properties in case the user changes the desktop -

392 globally, for example, through some kind of control panel. -

393 -

394 \li It performs event handling, meaning that it receives events -

395 from the underlying window system and dispatches them to the -

396 relevant widgets. You can send your own events to windows by -

397 using sendEvent() and postEvent(). -

398 -

399 \li It parses common command line arguments and sets its internal -

400 state accordingly. See the \l{QGuiApplication::QGuiApplication()} -

401 {constructor documentation} below for more details. -

402 -

403 \li It provides localization of strings that are visible to the -

404 user via translate(). -

405 -

406 \li It provides some magical objects like the clipboard(). -

407 -

408 \li It knows about the application's windows. You can ask which -

409 window is at a certain position using topLevelAt(), get a list of -

410 topLevelWindows(), etc. -

411 -

412 \li It manages the application's mouse cursor handling, see -

413 setOverrideCursor() -

414 -

415 \li It provides support for sophisticated \l{Session Management} -

416 {session management}. This makes it possible for applications -

417 to terminate gracefully when the user logs out, to cancel a -

418 shutdown process if termination isn't possible and even to -

419 preserve the entire application's state for a future session. -

420 See isSessionRestored(), sessionId() and commitDataRequest() and -

421 saveStateRequest() for details. -

422 \endlist -

423 -

424 Since the QGuiApplication object does so much initialization, it \e{must} be -

425 created before any other objects related to the user interface are created. -

426 QGuiApplication also deals with common command line arguments. Hence, it is -

427 usually a good idea to create it \e before any interpretation or -

428 modification of \c argv is done in the application itself. -

488 Initializes the window system and constructs an application object with -

489 \a argc command line arguments in \a argv. -

490 -

491 \warning The data referred to by \a argc and \a argv must stay valid for -

492 the entire lifetime of the QGuiApplication object. In addition, \a argc must -

493 be greater than zero and \a argv must contain at least one valid character -

494 string. -

495 -

496 The global \c qApp pointer refers to this application object. Only one -

497 application object should be created. -

498 -

499 This application object must be constructed before any \l{QPaintDevice} -

500 {paint devices} (including pixmaps, bitmaps etc.). -

501 -

502 \note \a argc and \a argv might be changed as Qt removes command line -

503 arguments that it recognizes. -

504 -

505 \section1 Supported Command Line Options -

506 -

507 All Qt programs automatically support a set of command-line options that -

508 allow modifying the way Qt will interact with the windowing system. Some of -

509 the options are also accessible via environment variables, which are the -

510 preferred form if the application can launch GUI sub-processes or other -

511 applications (environment variables will be inherited by child processes). -

512 When in doubt, use the environment variables. -

513 -

514 The options currently supported are the following: -

515 \list -

516 -

517 \li \c{-platform} \e {platformName[:options]}, specifies the -

518 \l{Qt Platform Abstraction} (QPA) plugin. -

519 -

520 Overridden by the \c QT_QPA_PLATFORM environment variable. -

521 \li \c{-platformpluginpath} \e path, specifies the path to platform -

522 plugins. -

523 -

524 Overridden by the \c QT_QPA_PLATFORM_PLUGIN_PATH environment -

525 variable. -

526 -

527 \li \c{-platformtheme} \e platformTheme, specifies the platform theme. -

528 -

529 Overridden by the \c QT_QPA_PLATFORMTHEME environment variable. -

530 -

531 \li \c{-plugin} \e plugin, specifies additional plugins to load. The argument -

532 may appear multiple times. -

533 -

534 Overridden by the \c QT_QPA_GENERIC_PLUGINS environment variable. -

535 -

536 \li \c{-qmljsdebugger=}, activates the QML/JS debugger with a specified port. -

537 The value must be of format \c{port:1234}\e{[,block]}, where -

538 \e block is optional -

539 and will make the application wait until a debugger connects to it. -

540 \li \c {-qwindowgeometry} \e geometry, specifies window geometry for -

541 the main window using the X11-syntax. For example: -

542 \c {-qwindowgeometry 100x100+50+50} -

543 \li \c {-qwindowicon}, sets the default window icon -

544 \li \c {-qwindowtitle}, sets the title of the first window -

545 \li \c{-reverse}, sets the application's layout direction to -

564 You can specify platform-specific arguments for the \c{-platform} option. -

565 Place them after the platform plugin name following a colon as a -

566 comma-separated list. For example, -

567 \c{-platform windows:dialogs=xp,fontengine=freetype}. -

568 -

569 The following parameters are available for \c {-platform windows}: -

570 -

571 \list -

572 \li \c {dialogs=[xp|none]}, \c xp uses XP-style native dialogs and -

573 \c none disables them. -

574 \li \c {fontengine=freetype}, uses the FreeType font engine. -

3213 This signal deals with \l{Session Management}{session management}. It is -

3214 emitted when the QSessionManager wants the application to commit all its -

3215 data. -

3216 -

3217 Usually this means saving all open files, after getting permission from -

3218 the user. Furthermore you may want to provide a means by which the user -

3219 can cancel the shutdown. -

3220 -

3221 You should not exit the application within this signal. Instead, -

3222 the session manager may or may not do this afterwards, depending on the -

3223 context. -

3241 This signal deals with \l{Session Management}{session management}. It is -

3242 invoked when the \l{QSessionManager}{session manager} wants the application -

3243 to preserve its state for a future session. -

3244 -

3245 For example, a text editor would create a temporary file that includes the -

3246 current contents of its edit buffers, the location of the cursor and other -

3247 aspects of the current editing session. -

3249 You should never exit the application within this signal. Instead, the -

3250 session manager may or may not do this afterwards, depending on the -
