207 \class QApplication -

208 \brief The QApplication class manages the GUI application's control -

209 flow and main settings. -

210 -

211 \inmodule QtWidgets -

212 -

213 QApplication specializes QGuiApplication with some functionality needed -

214 for QWidget-based applications. It handles widget specific initialization, -

215 finalization. -

216 -

217 For any GUI application using Qt, there is precisely \b one QApplication -

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

219 any given time. For non-QWidget based Qt applications, use QGuiApplication instead, -

220 as it does not depend on the \l QtWidgets library. -

221 -

222 Some GUI applications provide a special batch mode ie. provide command line -

223 arguments for executing tasks without manual intervention. In such non-GUI -

224 mode, it is often sufficient to instantiate a plain QCoreApplication to -

225 avoid unnecessarily initializing resources needed for a graphical user -

226 interface. The following example shows how to dynamically create an -

227 appropriate type of application instance: -

228 -

229 \snippet code/src_gui_kernel_qapplication.cpp 0 -

230 -

231 The QApplication object is accessible through the instance() function that -

232 returns a pointer equivalent to the global qApp pointer. -

233 -

234 QApplication's main areas of responsibility are: -

235 \list -

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

237 such as palette(), font() and doubleClickInterval(). It keeps -

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

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

240 -

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

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

243 relevant widgets. By using sendEvent() and postEvent() you can -

244 send your own events to widgets. -

245 -

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

247 state accordingly. See the \l{QApplication::QApplication()} -

248 {constructor documentation} below for more details. -

249 -

250 \li It defines the application's look and feel, which is -

251 encapsulated in a QStyle object. This can be changed at runtime -

252 with setStyle(). -

253 -

254 \li It specifies how the application is to allocate colors. See -

255 setColorSpec() for details. -

256 -

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

258 user via translate(). -

259 -

260 \li It provides some magical objects like the desktop() and the -

261 clipboard(). -

262 -

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

264 widget is at a certain position using widgetAt(), get a list of -

265 topLevelWidgets() and closeAllWindows(), etc. -

266 -

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

268 setOverrideCursor() -

269 \endlist -

270 -

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

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

273 QApplication also deals with common command line arguments. Hence, it is -

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

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

1327 Sets the color specification for the application to \a spec. -

1329 The color specification controls how the application allocates colors when -

1330 run on a display with a limited amount of colors, e.g. 8 bit / 256 color -

1331 displays. -

1332 -

1333 The color specification must be set before you create the QApplication -

1334 object. -

1335 -

1336 The options are: -

1337 \list -

1338 \li QApplication::NormalColor. This is the default color allocation -

1339 strategy. Use this option if your application uses buttons, menus, -

1340 texts and pixmaps with few colors. With this option, the -

1341 application uses system global colors. This works fine for most -

1342 applications under X11, but on the Windows platform, it may cause -

1343 dithering of non-standard colors. -

1344 \li QApplication::CustomColor. Use this option if your application -

1345 needs a small number of custom colors. On X11, this option is the -

1346 same as NormalColor. On Windows, Qt creates a Windows palette, and -

1347 allocates colors to it on demand. -

1348 \li QApplication::ManyColor. Use this option if your application is -

1349 very color hungry, e.g., it requires thousands of colors. \br -

1350 Under X11 the effect is: -

1351 \list -

1352 \li For 256-color displays which have at best a 256 color true -

1353 color visual, the default visual is used, and colors are -

1354 allocated from a color cube. The color cube is the 6x6x6 -

1355 (216 color) "Web palette" (the red, green, and blue -

1356 components always have one of the following values: 0x00, -

1357 0x33, 0x66, 0x99, 0xCC, or 0xFF), but the number of colors -

1358 can be changed by the \e -ncols option. The user can force -

1359 the application to use the true color visual with the -

1360 \l{QApplication::QApplication()}{-visual} option. -

1361 \li For 256-color displays which have a true color visual with -

1362 more than 256 colors, use that visual. Silicon Graphics X -

1363 servers this feature, for example. They provide an 8 bit -

1364 visual by default but can deliver true color when asked. -

1365 \endlist -

1366 On Windows, Qt creates a Windows palette, and fills it with a color -

1367 cube. -

1368 \endlist -

1369 -

1370 Be aware that the CustomColor and ManyColor choices may lead to colormap -

2920 If you support drag and drop in your application, and want to start a drag -

2921 and drop operation after the user has moved the cursor a certain distance -

2922 with a button held down, you should use this property's value as the -

2924 -

2925 For example, if the mouse position of the click is stored in \c startPos -

2945 Enters the main event loop and waits until exit() is called, then returns -

2946 the value that was set to exit() (which is 0 if exit() is called via -

2947 quit()). -

2948 -

2949 It is necessary to call this function to start event handling. The main -

2950 event loop receives events from the window system and dispatches these to -

2951 the application widgets. -

2952 -

2953 Generally, no user interaction can take place before calling exec(). As a -

2954 special case, modal widgets like QMessageBox can be used before calling -

2955 exec(), because modal widgets call exec() to start a local event loop. -

2956 -

2957 To make your application perform idle processing, i.e., executing a special -

2958 function whenever there are no pending events, use a QTimer with 0 timeout. -

2959 More advanced idle processing schemes can be achieved using processEvents(). -

2960 -

2961 We recommend that you connect clean-up code to the -

2962 \l{QCoreApplication::}{aboutToQuit()} signal, instead of putting it in your -

2963 application's \c{main()} function. This is because, on some platforms the -

2964 QApplication::exec() call may not return. For example, on the Windows -

2965 platform, when the user logs off, the system terminates the process after Qt -

2966 closes all top-level windows. Hence, there is \e{no guarantee} that the -

2967 application will have time to exit its event loop and execute code at the -

2968 end of the \c{main()} function, after the QApplication::exec() call. -
