Obsolete Members for QProcess

以下成员源于类 QProcess 已过时。 提供它们是为使旧源代码能继续工作。强烈建议不要在新代码中使用它们。

成员函数文档编制

QStringList QProcess:: environment () const

返回环境从 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.

另请参阅 processEnvironment (), setEnvironment ()，和 systemEnvironment ().

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

这是重载函数。

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

注意： 信号 finished 在此类中是重载。要使用函数指针句法连接到此信号，必须在静态铸造中指定信号类型，如此范例所示：

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 ()

另请参阅 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 () 函数。

另请参阅 environment (), setProcessEnvironment ()，和 systemEnvironment ().

void QProcess:: setReadChannelMode ( ProcessChannelMode mode )

使用 setProcessChannelMode ( mode ) 代替。

另请参阅 readChannelMode () 和 setProcessChannelMode ().
