Obsolete Members for QProcess
The following members of class QProcess are obsolete. They are provided to keep old source code working. We strongly advise against using them in new code.
| ||environment() const|
| ||pid() const|
| ||readChannelMode() const|
| ||setEnvironment(const QStringList &environment)|
| ||setReadChannelMode(ProcessChannelMode mode)|
Member Function Documentation
QStringList QProcess::environment() const
Returns the environment that QProcess will pass to its child process, or an empty QStringList if no environment has been set using setEnvironment(). If no environment has been set, the environment of the calling process will be used.
Note: The environment settings are ignored on Windows CE, as there is no concept of an environment.
[signal] void QProcess::error(QProcess::ProcessError error)
Use errorOccurred() instead.
Note: Signal error is overloaded in this class. To connect to this one using the function pointer syntax, you must specify the signal type in a static cast, as shown in this example:
This is an overloaded function.
Note: Signal finished is overloaded in this class. To connect to this one using the function pointer syntax, you must specify the signal type in a static cast, as shown in this example:
Q_PID QProcess::pid() const
Use processId() instead.
Returns the native process identifier for the running process, if available. If no process is currently running,
0 is returned.
Note: Unlike processId(), pid() returns an integer on Unix and a pointer on Windows.
ProcessChannelMode QProcess::readChannelMode() const
void QProcess::setEnvironment(const QStringList &environment)
Sets the environment that QProcess will pass to the child process. The parameter environment is a list of key=value pairs.
For example, the following code adds the environment variable
QProcess process; QStringList env = QProcess::systemEnvironment(); env << "TMPDIR=C:\\MyApp\\temp"; // Add an environment variable process.setEnvironment(env); process.start("myapp");
Note: This function is less efficient than the setProcessEnvironment() function.
void QProcess::setReadChannelMode(ProcessChannelMode mode)
Use setProcessChannelMode(mode) instead.
