A QProcess subclass for code-blocking process execution.
A Code-blocking (but not GUI-blocking) process executor
Use for example like:
KLFBlockProcess proc; QStringList args; args << "ls" << "/dev"; proc.startProcess(args); QString alldevices = proc.readStdoutString();
This class provides functionality for passing data to STDIN and getting data from STDOUT and STDERR afterwards.

KLFBlockProcess::KLFBlockProcess | ( | QObject * | parent = 0 | ) |
Normal constructor, like QProcess constructor

QByteArray KLFBlockProcess::getAllStderr | ( | ) | [inline] |
Returns all standard error output as a QByteArray. This function is to standardize the readStderr() and readAllStandardError() functions in QT 3 or QT 4 respectively

void KLFBlockProcess::setProcessAppEvents | ( | bool | processAppEvents | ) | [inline] |
Qt4 ONLY: specify whether or not to call regularly qApp->processEvents() while executing. This will prevent the GUI to freeze. Enabled is the default. However you can choose to disable this behavior by passing FALSE here.

bool KLFBlockProcess::startProcess | ( | QStringList | cmd, |
QByteArray | stdindata, | ||
QStringList | env = QStringList() |

) | [slot] |
Starts cmd (which is a list of arguments, the first being the program itself) and blocks until process stopped. The QT event loop is updated regularly so that the GUI doesn't freeze.
Read result with QProcess::readStdout() and QProcess::readStderr(), get process exit info with processNormalExit() and processExitStatus().

bool KLFBlockProcess::startProcess | ( | QStringList | cmd, |

Convenient function to be used in the case where program doesn't expect stdin data or if you chose to directly close stdin without writing anything to it.
