122 \brief The QProcessEnvironment class holds the environment variables that -

123 can be passed to a program. -

124 -

125 \ingroup io -

126 \ingroup misc -

127 \ingroup shared -

128 \reentrant -

129 \since 4.6 -

130 -

131 A process's environment is composed of a set of key=value pairs known as -

132 environment variables. The QProcessEnvironment class wraps that concept -

133 and allows easy manipulation of those variables. It's meant to be used -

134 along with QProcess, to set the environment for child processes. It -

135 cannot be used to change the current process's environment. -

136 -

137 The environment of the calling process can be obtained using -

138 QProcessEnvironment::systemEnvironment(). -

139 -

140 On Unix systems, the variable names are case-sensitive. Note that the -

141 Unix environment allows both variable names and contents to contain arbitrary -

142 binary data (except for the NUL character). QProcessEnvironment will preserve -

143 such variables, but does not support manipulating variables whose names or -

144 values cannot be encoded by the current locale settings (see -

145 QTextCodec::codecForLocale). -

146 -

147 On Windows, the variable names are case-insensitive, but case-preserving. -

148 QProcessEnvironment behaves accordingly. -

149 -

150 On Windows CE, the concept of environment does not exist. This class will -

151 keep the values set for compatibility with other platforms, but the values -

152 set will have no effect on the processes being created. -

460 \class QProcess -

461 \inmodule QtCore -

462 -

463 \brief The QProcess class is used to start external programs and -

464 to communicate with them. -

465 -

466 \ingroup io -

467 -

468 \reentrant -

469 -

470 \section1 Running a Process -

471 -

472 To start a process, pass the name and command line arguments of -

473 the program you want to run as arguments to start(). Arguments -

474 are supplied as individual strings in a QStringList. -

475 -

476 Alternatively, you can set the program to run with setProgram() -

477 and setArguments(), and then call start() or open(). -

478 -

479 For example, the following code snippet runs the analog clock -

480 example in the Fusion style on X11 platforms by passing strings -

481 containing "-style" and "fusion" as two items in the list of -

482 arguments: -

483 -

484 \snippet qprocess/qprocess-simpleexecution.cpp 0 -

485 \dots -

486 \snippet qprocess/qprocess-simpleexecution.cpp 1 -

487 \snippet qprocess/qprocess-simpleexecution.cpp 2 -

488 -

489 QProcess then enters the \l Starting state, and when the program -

490 has started, QProcess enters the \l Running state and emits -

491 started(). -

492 -

493 QProcess allows you to treat a process as a sequential I/O -

494 device. You can write to and read from the process just as you -

495 would access a network connection using QTcpSocket. You can then -

496 write to the process's standard input by calling write(), and -

497 read the standard output by calling read(), readLine(), and -

498 getChar(). Because it inherits QIODevice, QProcess can also be -

499 used as an input source for QXmlReader, or for generating data to -

500 be uploaded using QNetworkAccessManager. -

501 -

502 \note On Windows CE, reading and writing to a process -

503 is not supported. -

504 -

505 When the process exits, QProcess reenters the \l NotRunning state -

506 (the initial state), and emits finished(). -

507 -

508 The finished() signal provides the exit code and exit status of -

509 the process as arguments, and you can also call exitCode() to -

510 obtain the exit code of the last process that finished, and -

511 exitStatus() to obtain its exit status. If an error occurs at -

512 any point in time, QProcess will emit the errorOccurred() signal. -

513 You can also call error() to find the type of error that occurred -

514 last, and state() to find the current process state. -

515 -

516 \section1 Communicating via Channels -

517 -

518 Processes have two predefined output channels: The standard -

519 output channel (\c stdout) supplies regular console output, and -

520 the standard error channel (\c stderr) usually supplies the -

521 errors that are printed by the process. These channels represent -

522 two separate streams of data. You can toggle between them by -

523 calling setReadChannel(). QProcess emits readyRead() when data is -

524 available on the current read channel. It also emits -

525 readyReadStandardOutput() when new standard output data is -

526 available, and when new standard error data is available, -

527 readyReadStandardError() is emitted. Instead of calling read(), -

528 readLine(), or getChar(), you can explicitly read all data from -

529 either of the two channels by calling readAllStandardOutput() or -

530 readAllStandardError(). -

531 -

532 The terminology for the channels can be misleading. Be aware that -

533 the process's output channels correspond to QProcess's -

534 \e read channels, whereas the process's input channels correspond -

535 to QProcess's \e write channels. This is because what we read -

536 using QProcess is the process's output, and what we write becomes -

537 the process's input. -

538 -

539 QProcess can merge the two output channels, so that standard -

540 output and standard error data from the running process both use -

541 the standard output channel. Call setProcessChannelMode() with -

542 MergedChannels before starting the process to activate -

543 this feature. You also have the option of forwarding the output of -

544 the running process to the calling, main process, by passing -

545 ForwardedChannels as the argument. It is also possible to forward -

546 only one of the output channels - typically one would use -

547 ForwardedErrorChannel, but ForwardedOutputChannel also exists. -

548 Note that using channel forwarding is typically a bad idea in GUI -

549 applications - you should present errors graphically instead. -

550 -

551 Certain processes need special environment settings in order to -

552 operate. You can set environment variables for your process by -

553 calling setProcessEnvironment(). To set a working directory, call -

554 setWorkingDirectory(). By default, processes are run in the -

555 current working directory of the calling process. -

556 -

557 The positioning and the screen Z-order of windows belonging to -

558 GUI applications started with QProcess are controlled by -

559 the underlying windowing system. For Qt 5 applications, the -

560 positioning can be specified using the \c{-qwindowgeometry} -

561 command line option; X11 applications generally accept a -

562 \c{-geometry} command line option. -

563 -

564 \note On QNX, setting the working directory may cause all -

565 application threads, with the exception of the QProcess caller -

566 thread, to temporarily freeze during the spawning process, -

567 owing to a limitation in the operating system. -

568 -

569 \section1 Synchronous Process API -

570 -

571 QProcess provides a set of functions which allow it to be used -

572 without an event loop, by suspending the calling thread until -

573 certain signals are emitted: -

574 -

575 \list -

576 \li waitForStarted() blocks until the process has started. -

577 -

578 \li waitForReadyRead() blocks until new data is -

579 available for reading on the current read channel. -

580 -

581 \li waitForBytesWritten() blocks until one payload of -

582 data has been written to the process. -

583 -

584 \li waitForFinished() blocks until the process has finished. -

585 \endlist -

586 -

587 Calling these functions from the main thread (the thread that -

588 calls QApplication::exec()) may cause your user interface to -

589 freeze. -

590 -

591 The following example runs \c gzip to compress the string "Qt -

592 rocks!", without an event loop: -

593 -

594 \snippet process/process.cpp 0 -

595 -

596 \section1 Notes for Windows Users -

597 -

598 Some Windows commands (for example, \c dir) are not provided by -

599 separate applications, but by the command interpreter itself. -

600 If you attempt to use QProcess to execute these commands directly, -

601 it won't work. One possible solution is to execute the command -

602 interpreter itself (\c{cmd.exe} on some Windows systems), and ask -

603 the interpreter to execute the desired command. -

628 Pass one of these values to setProcessChannelMode() to set the -

629 current read channel mode. -

630 -

631 \value SeparateChannels QProcess manages the output of the -

632 running process, keeping standard output and standard error data -

633 in separate internal buffers. You can select the QProcess's -

634 current read channel by calling setReadChannel(). This is the -

635 default channel mode of QProcess. -

636 -

637 \value MergedChannels QProcess merges the output of the running -

638 process into the standard output channel (\c stdout). The -

639 standard error channel (\c stderr) will not receive any data. The -

640 standard output and standard error data of the running process -

641 are interleaved. -

642 -

643 \value ForwardedChannels QProcess forwards the output of the -

644 running process onto the main process. Anything the child process -

645 writes to its standard output and standard error will be written -

646 to the standard output and standard error of the main process. -

647 -

648 \value ForwardedErrorChannel QProcess manages the standard output -

649 of the running process, but forwards its standard error onto the -

650 main process. This reflects the typical use of command line tools -

651 as filters, where the standard output is redirected to another -

652 process or a file, while standard error is printed to the console -

653 for diagnostic purposes. -

654 (This value was introduced in Qt 5.2.) -

655 -

656 \value ForwardedOutputChannel Complementary to ForwardedErrorChannel. -

657 (This value was introduced in Qt 5.2.) -

658 -

659 \note Windows intentionally suppresses output from GUI-only -

660 applications to inherited consoles. -

661 This does \e not apply to output redirected to files or pipes. -

662 To forward the output of GUI-only applications on the console -

663 nonetheless, you must use SeparateChannels and do the forwarding -

664 yourself by reading the output and writing it to the appropriate -

665 output channels. -

2236 \overload -

2237 -

2238 Starts the command \a command in a new process. -

2239 The OpenMode is set to \a mode. -

2240 -

2241 \a command is a single string of text containing both the program name -

2242 and its arguments. The arguments are separated by one or more spaces. -

2243 For example: -

2244 -

2245 \snippet code/src_corelib_io_qprocess.cpp 5 -

2246 -

2247 Arguments containing spaces must be quoted to be correctly supplied to -

2248 the new process. For example: -

2249 -

2250 \snippet code/src_corelib_io_qprocess.cpp 6 -

2251 -

2252 Literal quotes in the \a command string are represented by triple quotes. -

2253 For example: -

2254 -

2255 \snippet code/src_corelib_io_qprocess.cpp 7 -

2256 -

2257 After the \a command string has been split and unquoted, this function -

2258 behaves like the overload which takes the arguments as a string list. -

2259 -

2260 You can disable this overload by defining \c -

2261 QT_NO_PROCESS_COMBINED_ARGUMENT_START when you compile your applications. -

2262 This can be useful if you want to ensure that you are not splitting arguments -

2263 unintentionally, for example. In virtually all cases, using the other overload -

2264 is the preferred method. -

2265 -

2266 On operating systems where the system API for passing command line -

2267 arguments to a subprocess natively uses a single string (Windows), one can -

2268 conceive command lines which cannot be passed via QProcess's portable -

2269 list-based API. In these rare cases you need to use setProgram() and -

2270 setNativeArguments() instead of this function. -
