106 | \class QProcessEnvironment | - |
107 | \inmodule QtCore | - |
108 | | - |
109 | \brief The QProcessEnvironment class holds the environment variables that | - |
110 | can be passed to a program. | - |
111 | | - |
112 | \ingroup io | - |
113 | \ingroup misc | - |
114 | \ingroup shared | - |
115 | \mainclass | - |
116 | \reentrant | - |
117 | \since 4.6 | - |
118 | | - |
119 | A process's environment is composed of a set of key=value pairs known as | - |
120 | environment variables. The QProcessEnvironment class wraps that concept | - |
121 | and allows easy manipulation of those variables. It's meant to be used | - |
122 | along with QProcess, to set the environment for child processes. It | - |
123 | cannot be used to change the current process's environment. | - |
124 | | - |
125 | The environment of the calling process can be obtained using | - |
126 | QProcessEnvironment::systemEnvironment(). | - |
127 | | - |
128 | On Unix systems, the variable names are case-sensitive. For that reason, | - |
129 | this class will not touch the names of the variables. Note as well that | - |
130 | Unix environment allows both variable names and contents to contain arbitrary | - |
131 | binary data (except for the NUL character), but this is not supported by | - |
132 | QProcessEnvironment. This class only supports names and values that are | - |
133 | encodable by the current locale settings (see QTextCodec::codecForLocale). | - |
134 | | - |
135 | On Windows, the variable names are case-insensitive. Therefore, | - |
136 | QProcessEnvironment will always uppercase the names and do case-insensitive | - |
137 | comparisons. | - |
138 | | - |
139 | On Windows CE, the concept of environment does not exist. This class will | - |
140 | keep the values set for compatibility with other platforms, but the values | - |
141 | set will have no effect on the processes being created. | - |

448 | \brief The QProcess class is used to start external programs and | - |
449 | to communicate with them. | - |

455 | \section1 Running a Process | - |
456 | | - |
457 | To start a process, pass the name and command line arguments of | - |
458 | the program you want to run as arguments to start(). Arguments | - |
459 | are supplied as individual strings in a QStringList. | - |
460 | | - |
461 | For example, the following code snippet runs the analog clock | - |
462 | example in the Fusion style on X11 platforms by passing strings | - |
463 | containing "-style" and "fusion" as two items in the list of | - |
464 | arguments: | - |
465 | | - |
466 | \snippet qprocess/qprocess-simpleexecution.cpp 0 | - |
467 | \dots | - |
468 | \snippet qprocess/qprocess-simpleexecution.cpp 1 | - |
469 | \snippet qprocess/qprocess-simpleexecution.cpp 2 | - |
470 | | - |
471 | QProcess then enters the \l Starting state, and when the program | - |
472 | has started, QProcess enters the \l Running state and emits | - |
473 | started(). | - |
474 | | - |
475 | QProcess allows you to treat a process as a sequential I/O | - |
476 | device. You can write to and read from the process just as you | - |
477 | would access a network connection using QTcpSocket. You can then | - |
478 | write to the process's standard input by calling write(), and | - |
479 | read the standard output by calling read(), readLine(), and | - |
480 | getChar(). Because it inherits QIODevice, QProcess can also be | - |
481 | used as an input source for QXmlReader, or for generating data to | - |
482 | be uploaded using QNetworkAccessManager. | - |
483 | | - |
484 | \note On Windows CE, reading and writing to a process | - |
485 | is not supported. | - |
486 | | - |
487 | When the process exits, QProcess reenters the \l NotRunning state | - |
488 | (the initial state), and emits finished(). | - |
489 | | - |
490 | The finished() signal provides the exit code and exit status of | - |
491 | the process as arguments, and you can also call exitCode() to | - |
492 | obtain the exit code of the last process that finished, and | - |
493 | exitStatus() to obtain its exit status. If an error occurs at | - |
494 | any point in time, QProcess will emit the error() signal. You | - |
495 | can also call error() to find the type of error that occurred | - |
496 | last, and state() to find the current process state. | - |
497 | | - |
498 | \section1 Communicating via Channels | - |
499 | | - |
500 | Processes have two predefined output channels: The standard | - |
501 | output channel (\c stdout) supplies regular console output, and | - |
502 | the standard error channel (\c stderr) usually supplies the | - |
503 | errors that are printed by the process. These channels represent | - |
504 | two separate streams of data. You can toggle between them by | - |
505 | calling setReadChannel(). QProcess emits readyRead() when data is | - |
506 | available on the current read channel. It also emits | - |
507 | readyReadStandardOutput() when new standard output data is | - |
508 | available, and when new standard error data is available, | - |
509 | readyReadStandardError() is emitted. Instead of calling read(), | - |
510 | readLine(), or getChar(), you can explicitly read all data from | - |
511 | either of the two channels by calling readAllStandardOutput() or | - |
512 | readAllStandardError(). | - |
513 | | - |
514 | The terminology for the channels can be misleading. Be aware that | - |
515 | the process's output channels correspond to QProcess's | - |
516 | \e read channels, whereas the process's input channels correspond | - |
517 | to QProcess's \e write channels. This is because what we read | - |
518 | using QProcess is the process's output, and what we write becomes | - |
519 | the process's input. | - |
520 | | - |
521 | QProcess can merge the two output channels, so that standard | - |
522 | output and standard error data from the running process both use | - |
523 | the standard output channel. Call setProcessChannelMode() with | - |
524 | MergedChannels before starting the process to activative | - |
525 | this feature. You also have the option of forwarding the output of | - |
526 | the running process to the calling, main process, by passing | - |
527 | ForwardedChannels as the argument. | - |
528 | | - |
529 | Certain processes need special environment settings in order to | - |
530 | operate. You can set environment variables for your process by | - |
531 | calling setEnvironment(). To set a working directory, call | - |
532 | setWorkingDirectory(). By default, processes are run in the | - |
533 | current working directory of the calling process. | - |
534 | | - |
535 | \note On QNX, setting the working directory may cause all | - |
536 | application threads, with the exception of the QProcess caller | - |
537 | thread, to temporarily freeze during the spawning process, | - |
538 | owing to a limitation in the operating system. | - |
539 | | - |
540 | \section1 Synchronous Process API | - |
541 | | - |
542 | QProcess provides a set of functions which allow it to be used | - |
543 | without an event loop, by suspending the calling thread until | - |
544 | certain signals are emitted: | - |
545 | | - |
546 | \list | - |
547 | \li waitForStarted() blocks until the process has started. | - |
548 | | - |
549 | \li waitForReadyRead() blocks until new data is | - |
550 | available for reading on the current read channel. | - |
551 | | - |
552 | \li waitForBytesWritten() blocks until one payload of | - |
553 | data has been written to the process. | - |
554 | | - |
555 | \li waitForFinished() blocks until the process has finished. | - |
556 | \endlist | - |
557 | | - |
558 | Calling these functions from the main thread (the thread that | - |
559 | calls QApplication::exec()) may cause your user interface to | - |
560 | freeze. | - |
561 | | - |
562 | The following example runs \c gzip to compress the string "Qt | - |
563 | rocks!", without an event loop: | - |

567 | \section1 Notes for Windows Users | - |
568 | | - |
569 | Some Windows commands (for example, \c dir) are not provided by | - |
570 | separate applications, but by the command interpreter itself. | - |
571 | If you attempt to use QProcess to execute these commands directly, | - |
572 | it won't work. One possible solution is to execute the command | - |
573 | interpreter itself (\c{cmd.exe} on some Windows systems), and ask | - |
574 | the interpreter to execute the desired command. | - |

601 | | - |
602 | \value SeparateChannels QProcess manages the output of the | - |

608 | \value MergedChannels QProcess merges the output of the running | - |
609 | process into the standard output channel (\c stdout). The | - |

611 | standard output and standard error data of the running process | - |

622 | To forward the output of GUI-only applications on the console | - |
