<P>
<p>The <a href="QProcess.html#QProcess(com.trolltech.qt.core.QObject)"><tt>QProcess</tt></a> class is used to start external programs and to communicate with them.</p>
<p>To start a process, pass the name and command line arguments of the program you want to run as arguments to <a href="QProcess.html#start(java.lang.String, java.util.List<java.lang.String>, com.trolltech.qt.core.QIODevice.OpenMode)"><tt>start</tt></a>. For example:</p>
<pre> QObject *parent;
...
QString program = "./path/to/Qt/examples/widgets/analogclock";
QStringList arguments;
arguments << "-style" << "motif";
QProcess *myProcess = new QProcess(parent);
myProcess->start(program, arguments);</pre>
<p><a href="QProcess.html#QProcess(com.trolltech.qt.core.QObject)"><tt>QProcess</tt></a> then enters the <a href="QProcess.html#ProcessState-enum">Starting</tt></a> state, and when the program has started, <a href="QProcess.html#QProcess(com.trolltech.qt.core.QObject)"><tt>QProcess</tt></a> enters the <a href="QProcess.html#ProcessState-enum">Running</tt></a> state and emits <a href="QProcess.html#started()"><tt>started</tt></a>.</p>
<p><a href="QProcess.html#QProcess(com.trolltech.qt.core.QObject)"><tt>QProcess</tt></a> allows you to treat a process as a sequential I/O device. You can write to and read from the process just as you would access a network connection using <a href="%2E%2E/network/QTcpSocket.html"><tt>QTcpSocket</tt></a>. You can then write to the process's standard input by calling <a href="QIODevice.html#write(com.trolltech.qt.core.QByteArray)"><tt>write</tt></a>, and read the standard output by calling <a href="QIODevice.html#read(long)"><tt>read</tt></a>, <a href="QIODevice.html#readLine(long)"><tt>readLine</tt></a>, and getChar(). Because it inherits <a href="QIODevice.html#QIODevice(com.trolltech.qt.core.QObject)"><tt>QIODevice</tt></a>, <a href="QProcess.html#QProcess(com.trolltech.qt.core.QObject)"><tt>QProcess</tt></a> can also be used as an input source for <a href="%2E%2E/xml/QXmlReader.html"><tt>QXmlReader</tt></a>, or for generating data to be uploaded using <a href="%2E%2E/network/QFtp.html"><tt>QFtp</tt></a>.</p>
<p>When the process exits, <a href="QProcess.html#QProcess(com.trolltech.qt.core.QObject)"><tt>QProcess</tt></a> reenters the <a href="QProcess.html#ProcessState-enum"><tt>NotRunning</tt></a> state (the initial state), and emits <a href="QProcess.html#finished(int)"><tt>finished</tt></a>.</p>
<p>The <a href="QProcess.html#finished(int)"><tt>finished</tt></a> signal provides the exit code and exit status of the process as arguments, and you can also call <a href="QProcess.html#exitCode()"><tt>exitCode</tt></a> to obtain the exit code of the last process that finished, and <a href="QProcess.html#exitStatus()"><tt>exitStatus</tt></a> to obtain its exit status. If an error occurs at any point in time, <a href="QProcess.html#QProcess(com.trolltech.qt.core.QObject)"><tt>QProcess</tt></a> will emit the <a href="QProcess.html#error()"><tt>error</tt></a> signal. You can also call <a href="QProcess.html#error()"><tt>error</tt></a> to find the type of error that occurred last, and <a href="QProcess.html#state()"><tt>state</tt></a> to find the current process state.</p>
<p>Processes have two predefined output channels: The standard output channel (<tt>stdout</tt>) supplies regular console output, and the standard error channel (<tt>stderr</tt>) usually supplies the errors that are printed by the process. These channels represent two separate streams of data. You can toggle between them by calling <a href="QProcess.html#setReadChannel(com.trolltech.qt.core.QProcess.ProcessChannel)"><tt>setReadChannel</tt></a>. <a href="QProcess.html#QProcess(com.trolltech.qt.core.QObject)"><tt>QProcess</tt></a> emits <a href="QProcess.html#readyRead()"><tt>readyRead</tt></a> when data is available on the current read channel. It also emits <a href="QProcess.html#readyReadStandardOutput()"><tt>readyReadStandardOutput</tt></a> when new standard output data is available, and when new standard error data is available, <a href="QProcess.html#readyReadStandardError()"><tt>readyReadStandardError</tt></a> is emitted. Instead of calling <a href="QIODevice.html#read(long)"><tt>read</tt></a>, <a href="QIODevice.html#readLine(long)"><tt>readLine</tt></a>, or getChar(), you can explicitly read all data from either of the two channels by calling <a href="QProcess.html#readAllStandardOutput()"><tt>readAllStandardOutput</tt></a> or <a href="QProcess.html#readAllStandardError()"><tt>readAllStandardError</tt></a>.</p>
<p>The terminology for the channels can be misleading. Be aware that the process's output channels correspond to <a href="QProcess.html#QProcess(com.trolltech.qt.core.QObject)"><tt>QProcess</tt></a>'s <i>read</i> channels, whereas the process's input channels correspond to <a href="QProcess.html#QProcess(com.trolltech.qt.core.QObject)"><tt>QProcess</tt></a>'s <i>write</i> channels. This is because what we read using <a href="QProcess.html#QProcess(com.trolltech.qt.core.QObject)"><tt>QProcess</tt></a> is the process's output, and what we write becomes the process's input.</p>
<p><a href="QProcess.html#QProcess(com.trolltech.qt.core.QObject)"><tt>QProcess</tt></a> can merge the two output channels, so that standard output and standard error data from the running process both use the standard output channel. Call <a href="QProcess.html#setProcessChannelMode(com.trolltech.qt.core.QProcess.ProcessChannelMode)"><tt>setProcessChannelMode</tt></a> with <a href="QProcess.html#ProcessChannelMode-enum"><tt>MergedChannels</tt></a> before starting the process to activative this feature. You also have the option of forwarding the output of the running process to the calling, main process, by passing <a href="QProcess.html#ProcessChannelMode-enum"><tt>ForwardedChannels</tt></a> as the argument.</p>
<p>Certain processes need special environment settings in order to operate. You can set environment variables for your process by calling <a href="QProcess.html#setEnvironment(java.util.List<java.lang.String>)"><tt>setEnvironment</tt></a>. To set a working directory, call <a href="QProcess.html#setWorkingDirectory(java.lang.String)"><tt>setWorkingDirectory</tt></a>. By default, processes are run in the current working directory of the calling process.</p>
<p><a href="QProcess.html#QProcess(com.trolltech.qt.core.QObject)"><tt>QProcess</tt></a> provides a set of functions which allow it to be used without an event loop, by suspending the calling thread until certain signals are emitted:</p>
<ul>
<li><a href="QProcess.html#waitForStarted(int)"><tt>waitForStarted</tt></a> blocks until the process has started.</li>
<li><a href="QProcess.html#waitForReadyRead(int)"><tt>waitForReadyRead</tt></a> blocks until new data is available for reading on the current read channel.</li>
<li><a href="QProcess.html#waitForBytesWritten(int)"><tt>waitForBytesWritten</tt></a> blocks until one payload of data has been written to the process.</li>
<li><a href="QProcess.html#waitForFinished(int)"><tt>waitForFinished</tt></a> blocks until the process has finished.</li>
</ul>
<p>Calling these functions from the main thread (the thread that calls QApplication::exec()) may cause your user interface to freeze.</p>
<p>The following example runs <tt>gzip</tt> to compress the string "Qt rocks!", without an event loop:</p>
<pre> QProcess gzip;
gzip.start("gzip", QStringList() << "-c");
if (!gzip.waitForStarted())
return false;
gzip.write("Qt rocks!");
gzip.closeWriteChannel();
if (!gzip.waitForFinished())
return false;
QByteArray result = gzip.readAll();</pre>
