Detailed Description

Support class with some KAUTHCORE_EXPORT methods useful to the helper's code.

This class provides the API to write the helper tool that executes your actions. You don't create instances of HelperSupport. Instead, you use its KAUTHCORE_EXPORT methods.

This them you can notify the application of progress in your action's execution and you can check if the application asked you to terminate it.

4.4

Function Documentation

◆ callerUid()

int KAuth::HelperSupport::callerUid ( )

Obtains the caller user id if available.

This method offers a way to obtain the unprivileged client's UID if possible. For example when a D-Bus-based backend is used this will resolve the caller of the D-Bus method and obtain its process' UID.

Since
5.74
Returns
caller UID or -1 when not available

◆ helperDebugHandler()

void KAuth::HelperSupport::helperDebugHandler ( QtMsgType type,
const QMessageLogContext & context,
const QString & msgStr )

Definition at line 106 of file helpersupport.cpp.

◆ helperMain()

int KAuth::HelperSupport::helperMain ( int argc,
char ** argv,
const char * id,
QObject * responder )

Method that implements the main function of the helper tool.

Do not call directly

This method is called in the proper way by the code generated by the KAUTH_HELPER_MAIN() macro, which creates a main() function for the helper tool. You shouldn't call this method directly.

Parameters
argcThe argc parameter from the main() function.
argvThe argv parameter from the main() function.
idThe helper ID as passed to the macro
responderThe responder object for the helper. The macro passes a default-constructed, heap-allocated object of the class specified as the last macro parameter

Definition at line 66 of file helpersupport.cpp.

◆ isStopped()

bool KAuth::HelperSupport::isStopped ( )

Check if the caller asked the helper to stop the execution.

This method will return true if the helper has been asked to stop the execution of the current action. If this happens, your helper should return (NOT exit). The meaning of the data you return in this case is application-dependent.

It's good practice to check it regularly if you have a long-running action

Returns
true if the helper has been asked to stop, false otherwise

◆ progressStep() [1/2]

void KAuth::HelperSupport::progressStep ( const QVariantMap & data)

Send a progressStep signal to the caller application.

You can use this method to notify progress information about the action execution. When you call this method, the KAuth::ExecuteJob object associated with the current action will emit the progressStep(QVariantMap) signal. The meaning of the data passed here is totally application dependent.

If you only need a simple percentage value, use the other overload which takes an int.

Parameters
dataThe progress data

Definition at line 143 of file helpersupport.cpp.

◆ progressStep() [2/2]

void KAuth::HelperSupport::progressStep ( int step)

Send a progressStep signal to the caller application.

You can use this method to notify progress information about the action execution. When you call this method, the KAuth::ExecuteJob object associated with the current action will emit the KJob::percent(KJob*, unsigned long) signal. The meaning of the integer passed here is totally application dependent, but you'll want to use it as a sort of percentage. If you need to be more expressive, use the other overload which takes a QVariantMap

Parameters
stepThe progress indicator
