<class name="QProcess" doc="/**
&lt;p&gt;The &lt;a href=&quot;QProcess.html#QProcess(com.trolltech.qt.core.QObject)&quot;&gt;&lt;tt&gt;QProcess&lt;/tt&gt;&lt;/a&gt; class is used to start external programs and to communicate with them.&lt;/p&gt;
&lt;p&gt;To start a process, pass the name and command line arguments of the program you want to run as arguments to &lt;a href=&quot;QProcess.html#start(java.lang.String, java.util.List&lt;java.lang.String&gt;, com.trolltech.qt.core.QIODevice.OpenMode)&quot;&gt;&lt;tt&gt;start&lt;/tt&gt;&lt;/a&gt;. For example:&lt;/p&gt;
&lt;pre&gt;        QObject *parent;
        ...
        QString program = &amp;quot;./path/to/Qt/examples/widgets/analogclock&amp;quot;;
        QStringList arguments;
        arguments &amp;lt;&amp;lt; &amp;quot;-style&amp;quot; &amp;lt;&amp;lt; &amp;quot;motif&amp;quot;;

        QProcess *myProcess = new QProcess(parent);
        myProcess-&amp;gt;start(program, arguments);&lt;/pre&gt;
&lt;p&gt;&lt;a href=&quot;QProcess.html#QProcess(com.trolltech.qt.core.QObject)&quot;&gt;&lt;tt&gt;QProcess&lt;/tt&gt;&lt;/a&gt; then enters the &lt;a href=&quot;QProcess.html#ProcessState-enum&quot;&gt;Starting&lt;/tt&gt;&lt;/a&gt; state, and when the program has started, &lt;a href=&quot;QProcess.html#QProcess(com.trolltech.qt.core.QObject)&quot;&gt;&lt;tt&gt;QProcess&lt;/tt&gt;&lt;/a&gt; enters the &lt;a href=&quot;QProcess.html#ProcessState-enum&quot;&gt;Running&lt;/tt&gt;&lt;/a&gt; state and emits &lt;a href=&quot;QProcess.html#started()&quot;&gt;&lt;tt&gt;started&lt;/tt&gt;&lt;/a&gt;.&lt;/p&gt;
&lt;p&gt;&lt;a href=&quot;QProcess.html#QProcess(com.trolltech.qt.core.QObject)&quot;&gt;&lt;tt&gt;QProcess&lt;/tt&gt;&lt;/a&gt; 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 &lt;a href=&quot;%2E%2E/network/QTcpSocket.html&quot;&gt;&lt;tt&gt;QTcpSocket&lt;/tt&gt;&lt;/a&gt;. You can then write to the process's standard input by calling &lt;a href=&quot;QIODevice.html#write(com.trolltech.qt.core.QByteArray)&quot;&gt;&lt;tt&gt;write&lt;/tt&gt;&lt;/a&gt;, and read the standard output by calling &lt;a href=&quot;QIODevice.html#read(long)&quot;&gt;&lt;tt&gt;read&lt;/tt&gt;&lt;/a&gt;, &lt;a href=&quot;QIODevice.html#readLine(long)&quot;&gt;&lt;tt&gt;readLine&lt;/tt&gt;&lt;/a&gt;, and getChar(). Because it inherits &lt;a href=&quot;QIODevice.html#QIODevice(com.trolltech.qt.core.QObject)&quot;&gt;&lt;tt&gt;QIODevice&lt;/tt&gt;&lt;/a&gt;, &lt;a href=&quot;QProcess.html#QProcess(com.trolltech.qt.core.QObject)&quot;&gt;&lt;tt&gt;QProcess&lt;/tt&gt;&lt;/a&gt; can also be used as an input source for &lt;a href=&quot;%2E%2E/xml/QXmlReader.html&quot;&gt;&lt;tt&gt;QXmlReader&lt;/tt&gt;&lt;/a&gt;, or for generating data to be uploaded using &lt;a href=&quot;%2E%2E/network/QFtp.html&quot;&gt;&lt;tt&gt;QFtp&lt;/tt&gt;&lt;/a&gt;.&lt;/p&gt;
&lt;p&gt;When the process exits, &lt;a href=&quot;QProcess.html#QProcess(com.trolltech.qt.core.QObject)&quot;&gt;&lt;tt&gt;QProcess&lt;/tt&gt;&lt;/a&gt; reenters the &lt;a href=&quot;QProcess.html#ProcessState-enum&quot;&gt;&lt;tt&gt;NotRunning&lt;/tt&gt;&lt;/a&gt; state (the initial state), and emits &lt;a href=&quot;QProcess.html#finished(int)&quot;&gt;&lt;tt&gt;finished&lt;/tt&gt;&lt;/a&gt;.&lt;/p&gt;
&lt;p&gt;The &lt;a href=&quot;QProcess.html#finished(int)&quot;&gt;&lt;tt&gt;finished&lt;/tt&gt;&lt;/a&gt; signal provides the exit code and exit status of the process as arguments, and you can also call &lt;a href=&quot;QProcess.html#exitCode()&quot;&gt;&lt;tt&gt;exitCode&lt;/tt&gt;&lt;/a&gt; to obtain the exit code of the last process that finished, and &lt;a href=&quot;QProcess.html#exitStatus()&quot;&gt;&lt;tt&gt;exitStatus&lt;/tt&gt;&lt;/a&gt; to obtain its exit status. If an error occurs at any point in time, &lt;a href=&quot;QProcess.html#QProcess(com.trolltech.qt.core.QObject)&quot;&gt;&lt;tt&gt;QProcess&lt;/tt&gt;&lt;/a&gt; will emit the &lt;a href=&quot;QProcess.html#error()&quot;&gt;&lt;tt&gt;error&lt;/tt&gt;&lt;/a&gt; signal. You can also call &lt;a href=&quot;QProcess.html#error()&quot;&gt;&lt;tt&gt;error&lt;/tt&gt;&lt;/a&gt; to find the type of error that occurred last, and &lt;a href=&quot;QProcess.html#state()&quot;&gt;&lt;tt&gt;state&lt;/tt&gt;&lt;/a&gt; to find the current process state.&lt;/p&gt;
&lt;p&gt;Processes have two predefined output channels: The standard output channel (&lt;tt&gt;stdout&lt;/tt&gt;) supplies regular console output, and the standard error channel (&lt;tt&gt;stderr&lt;/tt&gt;) 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 &lt;a href=&quot;QProcess.html#setReadChannel(com.trolltech.qt.core.QProcess.ProcessChannel)&quot;&gt;&lt;tt&gt;setReadChannel&lt;/tt&gt;&lt;/a&gt;. &lt;a href=&quot;QProcess.html#QProcess(com.trolltech.qt.core.QObject)&quot;&gt;&lt;tt&gt;QProcess&lt;/tt&gt;&lt;/a&gt; emits &lt;a href=&quot;QProcess.html#readyRead()&quot;&gt;&lt;tt&gt;readyRead&lt;/tt&gt;&lt;/a&gt; when data is available on the current read channel. It also emits &lt;a href=&quot;QProcess.html#readyReadStandardOutput()&quot;&gt;&lt;tt&gt;readyReadStandardOutput&lt;/tt&gt;&lt;/a&gt; when new standard output data is available, and when new standard error data is available, &lt;a href=&quot;QProcess.html#readyReadStandardError()&quot;&gt;&lt;tt&gt;readyReadStandardError&lt;/tt&gt;&lt;/a&gt; is emitted. Instead of calling &lt;a href=&quot;QIODevice.html#read(long)&quot;&gt;&lt;tt&gt;read&lt;/tt&gt;&lt;/a&gt;, &lt;a href=&quot;QIODevice.html#readLine(long)&quot;&gt;&lt;tt&gt;readLine&lt;/tt&gt;&lt;/a&gt;, or getChar(), you can explicitly read all data from either of the two channels by calling &lt;a href=&quot;QProcess.html#readAllStandardOutput()&quot;&gt;&lt;tt&gt;readAllStandardOutput&lt;/tt&gt;&lt;/a&gt; or &lt;a href=&quot;QProcess.html#readAllStandardError()&quot;&gt;&lt;tt&gt;readAllStandardError&lt;/tt&gt;&lt;/a&gt;.&lt;/p&gt;
&lt;p&gt;The terminology for the channels can be misleading. Be aware that the process's output channels correspond to &lt;a href=&quot;QProcess.html#QProcess(com.trolltech.qt.core.QObject)&quot;&gt;&lt;tt&gt;QProcess&lt;/tt&gt;&lt;/a&gt;'s &lt;i&gt;read&lt;/i&gt; channels, whereas the process's input channels correspond to &lt;a href=&quot;QProcess.html#QProcess(com.trolltech.qt.core.QObject)&quot;&gt;&lt;tt&gt;QProcess&lt;/tt&gt;&lt;/a&gt;'s &lt;i&gt;write&lt;/i&gt; channels. This is because what we read using &lt;a href=&quot;QProcess.html#QProcess(com.trolltech.qt.core.QObject)&quot;&gt;&lt;tt&gt;QProcess&lt;/tt&gt;&lt;/a&gt; is the process's output, and what we write becomes the process's input.&lt;/p&gt;
&lt;p&gt;&lt;a href=&quot;QProcess.html#QProcess(com.trolltech.qt.core.QObject)&quot;&gt;&lt;tt&gt;QProcess&lt;/tt&gt;&lt;/a&gt; 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 &lt;a href=&quot;QProcess.html#setProcessChannelMode(com.trolltech.qt.core.QProcess.ProcessChannelMode)&quot;&gt;&lt;tt&gt;setProcessChannelMode&lt;/tt&gt;&lt;/a&gt; with &lt;a href=&quot;QProcess.html#ProcessChannelMode-enum&quot;&gt;&lt;tt&gt;MergedChannels&lt;/tt&gt;&lt;/a&gt; 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 &lt;a href=&quot;QProcess.html#ProcessChannelMode-enum&quot;&gt;&lt;tt&gt;ForwardedChannels&lt;/tt&gt;&lt;/a&gt; as the argument.&lt;/p&gt;
&lt;p&gt;Certain processes need special environment settings in order to operate. You can set environment variables for your process by calling &lt;a href=&quot;QProcess.html#setEnvironment(java.util.List&lt;java.lang.String&gt;)&quot;&gt;&lt;tt&gt;setEnvironment&lt;/tt&gt;&lt;/a&gt;. To set a working directory, call &lt;a href=&quot;QProcess.html#setWorkingDirectory(java.lang.String)&quot;&gt;&lt;tt&gt;setWorkingDirectory&lt;/tt&gt;&lt;/a&gt;. By default, processes are run in the current working directory of the calling process.&lt;/p&gt;
&lt;p&gt;&lt;a href=&quot;QProcess.html#QProcess(com.trolltech.qt.core.QObject)&quot;&gt;&lt;tt&gt;QProcess&lt;/tt&gt;&lt;/a&gt; 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:&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;a href=&quot;QProcess.html#waitForStarted(int)&quot;&gt;&lt;tt&gt;waitForStarted&lt;/tt&gt;&lt;/a&gt; blocks until the process has started.&lt;/li&gt;
&lt;li&gt;&lt;a href=&quot;QProcess.html#waitForReadyRead(int)&quot;&gt;&lt;tt&gt;waitForReadyRead&lt;/tt&gt;&lt;/a&gt; blocks until new data is available for reading on the current read channel.&lt;/li&gt;
&lt;li&gt;&lt;a href=&quot;QProcess.html#waitForBytesWritten(int)&quot;&gt;&lt;tt&gt;waitForBytesWritten&lt;/tt&gt;&lt;/a&gt; blocks until one payload of data has been written to the process.&lt;/li&gt;
&lt;li&gt;&lt;a href=&quot;QProcess.html#waitForFinished(int)&quot;&gt;&lt;tt&gt;waitForFinished&lt;/tt&gt;&lt;/a&gt; blocks until the process has finished.&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;Calling these functions from the main thread (the thread that calls QApplication::exec()) may cause your user interface to freeze.&lt;/p&gt;
&lt;p&gt;The following example runs &lt;tt&gt;gzip&lt;/tt&gt; to compress the string &amp;quot;Qt rocks!&amp;quot;, without an event loop:&lt;/p&gt;
&lt;pre&gt;        QProcess gzip;
        gzip.start(&amp;quot;gzip&amp;quot;, QStringList() &amp;lt;&amp;lt; &amp;quot;-c&amp;quot;);
        if (!gzip.waitForStarted())
            return false;

        gzip.write(&amp;quot;Qt rocks!&amp;quot;);
        gzip.closeWriteChannel();

        if (!gzip.waitForFinished())
            return false;

        QByteArray result = gzip.readAll();&lt;/pre&gt;
