168 \class QFlags -

169 \inmodule QtCore -

170 \brief The QFlags class provides a type-safe way of storing -

171 OR-combinations of enum values. -

172 -

173 -

174 \ingroup tools -

175 -

176 The QFlags<Enum> class is a template class, where Enum is an enum -

177 type. QFlags is used throughout Qt for storing combinations of -

178 enum values. -

179 -

180 The traditional C++ approach for storing OR-combinations of enum -

181 values is to use an \c int or \c uint variable. The inconvenience -

182 with this approach is that there's no type checking at all; any -

183 enum value can be OR'd with any other enum value and passed on to -

184 a function that takes an \c int or \c uint. -

185 -

186 Qt uses QFlags to provide type safety. For example, the -

187 Qt::Alignment type is simply a typedef for -

188 QFlags<Qt::AlignmentFlag>. QLabel::setAlignment() takes a -

189 Qt::Alignment parameter, which means that any combination of -

190 Qt::AlignmentFlag values, or 0, is legal: -

191 -

192 \snippet code/src_corelib_global_qglobal.cpp 0 -

193 -

194 If you try to pass a value from another enum or just a plain -

195 integer other than 0, the compiler will report an error. If you -

196 need to cast integer values to flags in a untyped fashion, you can -

197 use the explicit QFlags constructor as cast operator. -

198 -

199 If you want to use QFlags for your own enum types, use -

200 the Q_DECLARE_FLAGS() and Q_DECLARE_OPERATORS_FOR_FLAGS(). -

201 -

202 Example: -

203 -

204 \snippet code/src_corelib_global_qglobal.cpp 1 -

205 -

206 You can then use the \c MyClass::Options type to store -

207 combinations of \c MyClass::Option values. -

208 -

209 \section1 Flags and the Meta-Object System -

210 -

211 The Q_DECLARE_FLAGS() macro does not expose the flags to the meta-object -

212 system, so they cannot be used by Qt Script or edited in Qt Designer. -

213 To make the flags available for these purposes, the Q_FLAG() macro must -

214 be used: -

215 -

216 \snippet code/src_corelib_global_qglobal.cpp meta-object flags -

217 -

218 \section1 Naming Convention -

219 -

220 A sensible naming convention for enum types and associated QFlags -

221 types is to give a singular name to the enum type (e.g., \c -

222 Option) and a plural name to the QFlags type (e.g., \c Options). -

223 When a singular name is desired for the QFlags type (e.g., \c -

224 Alignment), you can use \c Flag as the suffix for the enum type -

225 (e.g., \c AlignmentFlag). -

226 -

266 -

269 -

271 int, we effectively ensure that arbitrary enum values cannot be -

272 cast to a QFlags, whereas untyped enum values (i.e., \c int -

273 values) can. -

427 \macro Q_DISABLE_COPY(Class) -

428 \relates QObject -

429 -

430 Disables the use of copy constructors and assignment operators -

431 for the given \a Class. -

432 -

433 Instances of subclasses of QObject should not be thought of as -

434 values that can be copied or assigned, but as unique identities. -

435 This means that when you create your own subclass of QObject -

436 (director or indirect), you should \e not give it a copy constructor -

437 or an assignment operator. However, it may not enough to simply -

438 omit them from your class, because, if you mistakenly write some code -

439 that requires a copy constructor or an assignment operator (it's easy -

440 to do), your compiler will thoughtfully create it for you. You must -

441 do more. -

442 -

443 The curious user will have seen that the Qt classes derived -

444 from QObject typically include this macro in a private section: -

445 -

446 \snippet code/src_corelib_global_qglobal.cpp 43 -

447 -

448 It declares a copy constructor and an assignment operator in the -

449 private section, so that if you use them by mistake, the compiler -

450 will report an error. -

451 -

452 \snippet code/src_corelib_global_qglobal.cpp 44 -

453 -

454 But even this might not catch absolutely every case. You might be -

455 tempted to do something like this: -

456 -

457 \snippet code/src_corelib_global_qglobal.cpp 45 -

458 -

459 First of all, don't do that. Most compilers will generate code that -

460 uses the copy constructor, so the privacy violation error will be -

461 reported, but your C++ compiler is not required to generate code for -

462 this statement in a specific way. It could generate code using -

463 \e{neither} the copy constructor \e{nor} the assignment operator we -

464 made private. In that case, no error would be reported, but your -

465 application would probably crash when you called a member function -

466 of \c{w}. -

499 \title Global Qt Declarations -

500 \ingroup funclists -

501 -

502 \brief The <QtGlobal> header file includes the fundamental global -

503 declarations. It is included by most other Qt header files. -

504 -

505 The global declarations include \l{types}, \l{functions} and -

506 \l{macros}. -

507 -

508 The type definitions are partly convenience definitions for basic -

509 types (some of which guarantee certain bit-sizes on all platforms -

510 supported by Qt), partly types related to Qt message handling. The -

511 functions are related to generating messages, Qt version handling -

512 and comparing and adjusting object values. And finally, some of -

513 the declared macros enable programmers to add compiler or platform -

514 specific code to their applications, while others are convenience -

515 macros for larger operations. -

516 -

517 \section1 Types -

518 -

519 The header file declares several type definitions that guarantee a -

520 specified bit-size on all platforms supported by Qt for various -

521 basic types, for example \l qint8 which is a signed char -

522 guaranteed to be 8-bit on all platforms supported by Qt. The -

523 header file also declares the \l qlonglong type definition for \c -

524 {long long int } (\c __int64 on Windows). -

525 -

526 Several convenience type definitions are declared: \l qreal for \c -

527 double, \l uchar for \c unsigned char, \l uint for \c unsigned -

528 int, \l ulong for \c unsigned long and \l ushort for \c unsigned -

529 short. -

530 -

531 Finally, the QtMsgType definition identifies the various messages -

532 that can be generated and sent to a Qt message handler; -

533 QtMessageHandler is a type definition for a pointer to a function with -

534 the signature -

535 \c {void myMessageHandler(QtMsgType, const QMessageLogContext &, const char *)}. -

536 QMessageLogContext class contains the line, file, and function the -

537 message was logged at. This information is created by the QMessageLogger -

538 class. -

539 -

540 \section1 Functions -

541 -

542 The <QtGlobal> header file contains several functions comparing -

543 and adjusting an object's value. These functions take a template -

544 type as argument: You can retrieve the absolute value of an object -

545 using the qAbs() function, and you can bound a given object's -

546 value by given minimum and maximum values using the qBound() -

547 function. You can retrieve the minimum and maximum of two given -

548 objects using qMin() and qMax() respectively. All these functions -

549 return a corresponding template type; the template types can be -

550 replaced by any other type. -

551 -

552 Example: -

553 -

554 \snippet code/src_corelib_global_qglobal.cpp 3 -

555 -

556 <QtGlobal> also contains functions that generate messages from the -

557 given string argument: qDebug(), qInfo(), qWarning(), qCritical(), -

558 and qFatal(). These functions call the message handler -

559 with the given message. -

560 -

561 Example: -

562 -

563 \snippet code/src_corelib_global_qglobal.cpp 4 -

564 -

565 The remaining functions are qRound() and qRound64(), which both -

566 accept a \l qreal value as their argument returning the value -

567 rounded up to the nearest integer and 64-bit integer respectively, -

568 the qInstallMessageHandler() function which installs the given -

569 QtMessageHandler, and the qVersion() function which returns the -

570 version number of Qt at run-time as a string. -

571 -

572 \section1 Macros -

573 -

574 The <QtGlobal> header file provides a range of macros (Q_CC_*) -

575 that are defined if the application is compiled using the -

576 specified platforms. For example, the Q_CC_SUN macro is defined if -

577 the application is compiled using Forte Developer, or Sun Studio -

578 C++. The header file also declares a range of macros (Q_OS_*) -

579 that are defined for the specified platforms. For example, -

580 Q_OS_UNIX which is defined for the Unix-based systems. -

581 -

582 The purpose of these macros is to enable programmers to add -

583 compiler or platform specific code to their application. -

584 -

585 The remaining macros are convenience macros for larger operations: -

586 The QT_TRANSLATE_NOOP() and QT_TR_NOOP() macros provide the -

587 possibility of marking text for dynamic translation, -

588 i.e. translation without changing the stored source text. The -

589 Q_ASSERT() and Q_ASSERT_X() enables warning messages of various -

590 level of refinement. The Q_FOREACH() and foreach() macros -

591 implement Qt's foreach loop. -

593 The Q_INT64_C() and Q_UINT64_C() macros wrap signed and unsigned -

594 64-bit integer literals in a platform-independent way. The -

595 Q_CHECK_PTR() macro prints a warning containing the source code's -

596 file name and line number, saying that the program ran out of -

597 memory, if the pointer is 0. The qPrintable() and qUtf8Printable() -

598 macros represent an easy way of printing text. -

599 -

600 Finally, the QT_POINTER_SIZE macro expands to the size of a -

601 pointer in bytes, and the QT_VERSION and QT_VERSION_STR macros -

602 expand to a numeric value or a string, respectively, specifying -

603 Qt's version number, i.e the version the application is compiled -

604 against. -

2459 The returned value is composed of three or more parts, separated by dashes -

2460 ("-"). They are: -

2461 -

2462 \table -

2463 \header \li Component \li Value -

2464 \row \li CPU Architecture \li The same as QSysInfo::buildCpuArchitecture(), such as "arm", "i386", "mips" or "x86_64" -

2465 \row \li Endianness \li "little_endian" or "big_endian" -

2466 \row \li Word size \li Whether it's a 32- or 64-bit application. Possible values are: -

2467 "llp64" (Windows 64-bit), "lp64" (Unix 64-bit), "ilp32" (32-bit) -

2468 \row \li (Optional) ABI \li Zero or more components identifying different ABIs possible in this architecture. -

2469 Currently, Qt has optional ABI components for ARM and MIPS processors: one -

2470 component is the main ABI (such as "eabi", "o32", "n32", "o64"); another is -

2471 whether the calling convention is using hardware floating point registers ("hardfloat" -

2472 is present). -

2473 -

2474 Additionally, if Qt was configured with \c{-qreal float}, the ABI option tag "qreal_float" -

2475 will be present. If Qt was configured with another type as qreal, that type is present after -

2476 "qreal_", with all characters other than letters and digits escaped by an underscore, followed -

2477 by two hex digits. For example, \c{-qreal long double} becomes "qreal_long_20double". -

2877 Causes the compiler to assume that \a expr is \c true. This macro is useful -

2878 for improving code generation, by providing the compiler with hints about -

2879 conditions that it would not otherwise know about. However, there is no -

2880 guarantee that the compiler will actually use those hints. -

2881 -

2882 This macro could be considered a "lighter" version of \l{Q_ASSERT()}. While -

2883 Q_ASSERT will abort the program's execution if the condition is \c false, -

2884 Q_ASSUME will tell the compiler not to generate code for those conditions. -

2885 Therefore, it is important that the assumptions always hold, otherwise -

2886 undefined behaviour may occur. -

2887 -

2888 If \a expr is a constantly \c false condition, Q_ASSUME will tell the compiler -

2889 that the current code execution cannot be reached. That is, Q_ASSUME(false) -

2890 is equivalent to Q_UNREACHABLE(). -

2902 \macro void Q_UNREACHABLE() -

2903 \relates <QtGlobal> -

2904 \since 5.0 -

2905 -

2906 Tells the compiler that the current point cannot be reached by any -

2907 execution, so it may optimize any code paths leading here as dead code, as -

2908 well as code continuing from here. -

2909 -

2910 This macro is useful to mark impossible conditions. For example, given the -

2911 following enum: -

2912 -

2913 \snippet code/src_corelib_global_qglobal.cpp qunreachable-enum -

2914 -

2915 One can write a switch table like so: -

2916 -

2917 \snippet code/src_corelib_global_qglobal.cpp qunreachable-switch -

2918 -

2919 The advantage of inserting Q_UNREACHABLE() at that point is that the -

2920 compiler is told not to generate code for a shape variable containing that -

2921 value. If the macro is missing, the compiler will still generate the -

2922 necessary comparisons for that value. If the case label were removed, some -

2923 compilers could produce a warning that some enum values were not checked. -

2924 -

2925 By using this macro in impossible conditions, code coverage may be improved -

2926 as dead code paths may be eliminated. -

2927 -

2928 In debug builds the condition is enforced by an assert to facilitate debugging. -

2934 \macro void Q_CHECK_PTR(void *pointer) -

2935 \relates <QtGlobal> -

2936 -

2937 If \a pointer is 0, prints a message containing the source -

2938 code's file name and line number, saying that the program ran out -

2939 of memory and aborts program execution. It throws \c std::bad_alloc instead -

2940 if exceptions are enabled. -

2941 -

2942 Q_CHECK_PTR does nothing if \c QT_NO_DEBUG and \c QT_NO_EXCEPTIONS were -

2943 defined during compilation. Therefore you must not use Q_CHECK_PTR to check -

2944 for successful memory allocations because the check will be disabled in -

2945 some cases. -

2946 -

2947 Example: -

2948 -

2968 more specifically is compiler dependent. With GNU GCC it is typically the function signature, -

2969 while with other compilers it might be the line and column number. -

3634 Returns a translated string identified by \a id. -

3635 If no matching string is found, the id itself is returned. This -

3638 If \a n >= 0, all occurrences of \c %n in the resulting string -

3639 are replaced with a decimal representation of \a n. In addition, -

3640 depending on \a n's value, the translation text may vary. -

3805 \a Flags can be one of the following: -

3806 -

3807 \list -

3808 \li \c Q_PRIMITIVE_TYPE specifies that \a Type is a POD (plain old -

3809 data) type with no constructor or destructor, or else a type where -

3810 every bit pattern is a valid object and memcpy() creates a valid -

3811 independent copy of the object. -

3812 \li \c Q_MOVABLE_TYPE specifies that \a Type has a constructor -

3813 and/or a destructor but can be moved in memory using \c -

3814 memcpy(). Note: despite the name, this has nothing to do with move -

3815 constructors or C++ move semantics. -

3816 \li \c Q_COMPLEX_TYPE (the default) specifies that \a Type has -

3817 constructors and/or a destructor and that it may not be moved -

3824 -

3825 An example of a non-POD "primitive" type is QUuid: Even though -

3826 QUuid has constructors (and therefore isn't POD), every bit -

3827 pattern still represents a valid object, and memcpy() can be used -

3889 -

3890 This macro can be used to determine the byte order your system -

3891 uses for storing data in memory. i.e., whether your system is -

3892 little-endian or big-endian. It is set by Qt to one of the macros -

3893 Q_LITTLE_ENDIAN or Q_BIG_ENDIAN. You normally won't need to worry -

3894 about endian-ness, but you might, for example if you need to know -

3895 which byte of an integer or UTF-16 character is stored in the -

3896 lowest address. Endian-ness is important in networking, where -

3897 computers with different values for Q_BYTE_ORDER must pass data -

3898 back and forth. -

4402 In general, use of the Q_DECL_NOEXCEPT macro is preferred over -

4403 Q_DECL_NOTHROW, because it exhibits well-defined behavior and -

4404 supports the more powerful Q_DECL_NOEXCEPT_EXPR variant. However, -

4405 use of Q_DECL_NOTHROW has the advantage that Windows builds -

4406 benefit on a wide range or compiler versions that do not yet -

4407 support the C++11 noexcept feature. -

4408 -

4409 It may therefore be beneficial to use Q_DECL_NOTHROW and emulate -

4410 the C++11 behavior manually with an embedded try/catch. -

4411 -

4412 Qt provides the QT_TERMINATE_ON_EXCEPTION(expr) macro for this -

4413 purpose. It either expands to \c expr (if Qt is compiled without -

4414 exception support or the compiler supports C++11 noexcept -

4415 semantics) or to -

4416 \code -

4417 try { expr; } catch(...) { qTerminate(); } -

4418 \endcode -

4419 otherwise. -

4420 -

4421 Since this macro expands to just \c expr if the compiler supports -

4422 C++11 noexcept, expecting the compiler to take over responsibility -

4423 of calling std::terminate() in that case, it should not be used -

4424 outside Q_DECL_NOTHROW functions. -

4478 This macro can be used to declare an overriding virtual -

4504 class, respectively. -

4505 -

4506 It expands to "final" if your compiler supports that C++11 -

4508 supports something close enough to the C++11 semantics, or to -

4509 nothing otherwise. -
