QStringList QProcess:: environment () const

This function is deprecated. We strongly advise against using it in new code.

返迴環境從 QProcess will pass to its child process, or an empty QStringList if no environment has been set using setEnvironment ()。若沒有設置環境，將使用調用進程的環境。

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

void QProcess:: setEnvironment (const QStringList & environment )

This function is deprecated. We strongly advise against using it in new code.

Sets the environment that QProcess will pass to the child process. The parameter environment is a list of key=value pairs.

例如，以下代碼添加環境變量 TMPDIR :

QProcess process;
QStringList env = QProcess::systemEnvironment();
env << "TMPDIR=C:\\MyApp\\temp"; // Add an environment variable
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 ().
