Static Public Members

KSignalHandler * self()

Detailed Description

Allows getting ANSI C signals and forward them onto the Qt eventloop.

It's a singleton as it relies on static data getting defined.

{
  KSignalHandler::self()->watchSignal(SIGTERM);
  connect(KSignalHandler::self(), &KSignalHandler::signalReceived,
          this, &SomeClass::handleSignal);
  job->start();
}

Member Function Documentation

`[static]` KSignalHandler *KSignalHandler::self()

Fetches an instance we can use to register our signals.

`[signal]` void KSignalHandler::signalReceived(int signal)

Notifies that signal is emitted.

To catch a signal, we need to make sure it's registered using @m watchSignal.

See also watchSignal.

void KSignalHandler::watchSignal(int signal)

Adds signal to be watched for. Once the process is notified about this signal, @m signalReceived will be emitted with the same signal as an argument.

See also signalReceived.
