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

129 can be passed to a program. -

130 -

131 \ingroup io -

132 \ingroup misc -

133 \ingroup shared -

134 \reentrant -

135 \since 4.6 -

136 -

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

138 environment variables. The QProcessEnvironment class wraps that concept -

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

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

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

142 -

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

144 QProcessEnvironment::systemEnvironment(). -

145 -

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

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

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

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

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

151 QTextCodec::codecForLocale). -

152 -

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

154 QProcessEnvironment behaves accordingly. -

462 \class QProcess -

463 \inmodule QtCore -

464 -

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

466 to communicate with them. -

467 -

468 \ingroup io -

469 -

470 \reentrant -

471 -

472 \section1 Running a Process -

473 -

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

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

476 are supplied as individual strings in a QStringList. -

477 -

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

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

480 -

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

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

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

484 arguments: -

485 -

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

487 \dots -

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

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

490 -

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

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

493 started(). -

494 -

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

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

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

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

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

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

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

502 be uploaded using QNetworkAccessManager. -

503 -

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

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

506 -

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

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

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

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

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

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

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

514 -

515 \section1 Communicating via Channels -

516 -

517 Processes have two predefined output channels: The standard -

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

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

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

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

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

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

524 readyReadStandardOutput() when new standard output data is -

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

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

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

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

529 readAllStandardError(). -

530 -

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

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

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

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

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

536 the process's input. -

537 -

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

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

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

541 MergedChannels before starting the process to activate -

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

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

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

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

546 ForwardedErrorChannel, but ForwardedOutputChannel also exists. -

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

548 applications - you should present errors graphically instead. -

549 -

550 Certain processes need special environment settings in order to -

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

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

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

554 current working directory of the calling process. -

555 -

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

557 GUI applications started with QProcess are controlled by -

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

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

560 command line option; X11 applications generally accept a -

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

562 -

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

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

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

566 owing to a limitation in the operating system. -

567 -

568 \section1 Synchronous Process API -

569 -

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

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

572 certain signals are emitted: -

573 -

574 \list -

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

576 -

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

578 available for reading on the current read channel. -

579 -

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

581 data has been written to the process. -

582 -

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

584 \endlist -

585 -

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

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

588 freeze. -

589 -

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

591 rocks!", without an event loop: -

595 \section1 Notes for Windows Users -

596 -

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

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

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

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

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

602 the interpreter to execute the desired command. -

628 current read channel mode. -

629 -

630 \value SeparateChannels QProcess manages the output of the -

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

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

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

634 default channel mode of QProcess. -

635 -

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

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

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

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

640 are interleaved. -

641 -

642 \value ForwardedChannels QProcess forwards the output of the -

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

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

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

646 -

647 \value ForwardedErrorChannel QProcess manages the standard output -

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

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

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

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

652 for diagnostic purposes. -

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

654 -

655 \value ForwardedOutputChannel Complementary to ForwardedErrorChannel. -

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

657 -

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

659 applications to inherited consoles. -

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

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

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

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

664 output channels. -

748 \typedef QProcess::CreateProcessArgumentModifier -

749 \note This typedef is only available on desktop Windows. -

750 -

751 On Windows, QProcess uses the Win32 API function \c CreateProcess to -

752 start child processes. While QProcess provides a comfortable way to start -

753 processes without worrying about platform -

754 details, it is in some cases desirable to fine-tune the parameters that are -

755 passed to \c CreateProcess. This is done by defining a -

756 \c CreateProcessArgumentModifier function and passing it to -

757 \c setCreateProcessArgumentsModifier. -

758 -

759 A \c CreateProcessArgumentModifier function takes one parameter: a pointer -

760 to a \c CreateProcessArguments struct. The members of this struct will be -

761 passed to \c CreateProcess after the \c CreateProcessArgumentModifier -

762 function is called. -

763 -

764 The following example demonstrates how to pass custom flags to -

765 \c CreateProcess. -

766 When starting a console process B from a console process A, QProcess will -

767 reuse the console window of process A for process B by default. In this -

768 example, a new console window with a custom color scheme is created for the -

769 child process B instead. -

2229 \overload -

2230 -

2231 Starts the command \a command in a new process. -

2232 The OpenMode is set to \a mode. -

2233 -

2234 \a command is a single string of text containing both the program name -

2235 and its arguments. The arguments are separated by one or more spaces. -

2236 For example: -

2237 -

2238 \snippet code/src_corelib_io_qprocess.cpp 5 -

2239 -

2240 Arguments containing spaces must be quoted to be correctly supplied to -

2241 the new process. For example: -

2242 -

2243 \snippet code/src_corelib_io_qprocess.cpp 6 -

2244 -

2245 Literal quotes in the \a command string are represented by triple quotes. -

2246 For example: -

2247 -

2248 \snippet code/src_corelib_io_qprocess.cpp 7 -

2249 -

2250 After the \a command string has been split and unquoted, this function -

2251 behaves like the overload which takes the arguments as a string list. -

2252 -

2253 You can disable this overload by defining \c -

2254 QT_NO_PROCESS_COMBINED_ARGUMENT_START when you compile your applications. -

2255 This can be useful if you want to ensure that you are not splitting arguments -

2256 unintentionally, for example. In virtually all cases, using the other overload -

2257 is the preferred method. -

2258 -

2259 On operating systems where the system API for passing command line -

2260 arguments to a subprocess natively uses a single string (Windows), one can -

2261 conceive command lines which cannot be passed via QProcess's portable -

2262 list-based API. In these rare cases you need to use setProgram() and -

2263 setNativeArguments() instead of this function. -
