QStringList QProcess:: environment () const

返迴環境從 QProcess will use when starting a process, or an empty QStringList if no environment has been set using setEnvironment () or setEnvironmentHash(). If no environment has been set, the environment of the calling process will be used.

注意： The environment settings are ignored on Windows CE and Symbian, as there is no concept of an environment.

另請參閱 processEnvironment (), setEnvironment ()，和 systemEnvironment ().

[signal] void QProcess:: finished ( int exitCode )

這是重載函數。

Use finished(int exitCode , QProcess::ExitStatus status) instead.

注意： 信號 finished 在此類中是重載。要使用函數指針句法連接到此信號，必須在靜態鑄造中指定信號類型，如此範例所示：

connect(process, static_cast<void(QProcess::*)(int)>(&QProcess::finished),
    [=](int exitCode){ /* ... */ });
					

ProcessChannelMode QProcess:: readChannelMode () const

Returns the read channel mode of the QProcess . This function is equivalent to processChannelMode ()

另請參閱 setReadChannelMode () 和 processChannelMode ().

void QProcess:: setEnvironment (const QStringList & environment )

Sets the environment that QProcess will use when starting a process to the environment specified which consists of a list of key=value pairs.

For example, the following code adds the C:\\BIN directory to the list of executable paths ( PATHS ) on Windows:

QProcess process;
QStringList env = QProcess::systemEnvironment();
env << "TMPDIR=C:\\MyApp\\temp"; // Add an environment variable
env.replaceInStrings(QRegExp("^PATH=(.*)", Qt::CaseInsensitive), "PATH=\\1;C:\\Bin");
process.setEnvironment(env);
process.start("myapp");
					

注意： This function is less efficient than the setProcessEnvironment () 函數。

另請參閱 environment (), setProcessEnvironment ()，和 systemEnvironment ().

void QProcess:: setReadChannelMode ( ProcessChannelMode mode )

使用 setProcessChannelMode ( mode ) 代替。

另請參閱 readChannelMode () 和 setProcessChannelMode ().
