Protected Slots inherited from KCompositeJob
virtual void	slotInfoMessage (KJob *job, const QString &message)

virtual void	slotResult (KJob *job)

Detailed Description

The base class for all jobs.

For all jobs created in an application, the code looks like

KIO::Job* job = KIO::someoperation(some parameters);

connect(job, &KJob::result, this, &MyClass::slotResult);

KIO::Job

The base class for all jobs.

KJob::result

void result(KJob *job)

QObject::connect

QMetaObject::Connection connect(const QObject *sender, PointerToMemberFunction signal, Functor functor)

(other connects, specific to the job)

And slotResult is usually at least:

void MyClass::slotResult(KJob *job)
{
  if (job->error()) {
    job->uiDelegate()->showErrorMessage();
  }
}

Member Function Documentation

◆ addMetaData() [1/2]

void Job::addMetaData ( const QMap< QString, QString > & values )

Add key/value pairs to the meta data that is sent to the worker.

If a certain key already existed, it will be overridden.

Parameters

values the meta data to add

See also: setMetaData(); mergeMetaData()

Definition at line 226 of file job.cpp.

◆ addMetaData() [2/2]

void Job::addMetaData	(	const QString &	key,
		const QString &	value )

Add key/value pair to the meta data that is sent to the worker.

Parameters

key	the key of the meta data
value	the value of the meta data

See also: setMetaData(); mergeMetaData()

Definition at line 221 of file job.cpp.

◆ addSubjob()

bool Job::addSubjob ( KJob * job )

overrideprotectedvirtual

Add a job that has to be finished before a result is emitted.

This has obviously to be called before the finish signal is emitted by the worker.

Parameters

job	the subjob to add

Reimplemented from KCompositeJob.

Definition at line 56 of file job.cpp.

◆ connected

void KIO::Job::connected ( KIO::Job * job )

signal

Emitted when the worker successfully connected to the host.

There is no guarantee the worker will send this, and this is currently unused (in the applications).

Parameters

job	the job that emitted this signal

◆ detailedErrorStrings()

QStringList KIO::Job::detailedErrorStrings	(	const QUrl *	reqUrl = nullptr,
		int	method = -1 ) const

Converts an error code and a non-i18n error message into i18n strings suitable for presentation in a detailed error message box.

Parameters

reqUrl	the request URL that generated this error message
method	the method that generated this error message (unimplemented)

Returns: the following strings: title, error + description, causes+solutions

Definition at line 271 of file job_error.cpp.

◆ doKill()

bool Job::doKill ( )

overrideprotectedvirtual

Abort this job.

This kills all subjobs and deletes the job.

Reimplemented from KJob.

Reimplemented in KIO::SimpleJob.

Definition at line 157 of file job.cpp.

◆ doResume()

bool Job::doResume ( )

overrideprotectedvirtual

Resume this job.

See also: suspend

Reimplemented from KJob.

Reimplemented in KIO::SimpleJob, and KIO::TransferJob.

Definition at line 179 of file job.cpp.

◆ doSuspend()

bool Job::doSuspend ( )

overrideprotectedvirtual

Suspend this job.

See also: resume

Reimplemented from KJob.

Reimplemented in KIO::SimpleJob.

Definition at line 168 of file job.cpp.

◆ errorString()

QString KIO::Job::errorString ( ) const

overridevirtual

Converts an error code and a non-i18n error message into an error message in the current language.

The low level (non-i18n) error message (usually a url) is put into the translated error message using %1.

Example for errid == ERR_CANNOT_OPEN_FOR_READING:

i18n("Could not read\n%1", errortext);

i18n

QString i18n(const char *text, const TYPE &arg...)

Use this to display the error yourself, but for a dialog box use uiDelegate()->showErrorMessage(). Do not call it if error() is not 0.

Returns: the error message and if there is no error, a message telling the user that the app is broken, so check with error() whether there is an error

Reimplemented from KJob.

Definition at line 26 of file job_error.cpp.

◆ mergeMetaData()

void Job::mergeMetaData ( const QMap< QString, QString > & values )

Add key/value pairs to the meta data that is sent to the worker.

If a certain key already existed, it will remain unchanged.

Parameters

values the meta data to merge

See also: setMetaData(); addMetaData()

Definition at line 234 of file job.cpp.

◆ metaData()

MetaData Job::metaData ( ) const

Get meta data received from the worker.

(Valid when first data is received and/or worker is finished)

Returns: the job's meta data

Definition at line 205 of file job.cpp.

◆ outgoingMetaData()

MetaData Job::outgoingMetaData ( ) const

. For the scheduler. Do not use.

Definition at line 245 of file job.cpp.

◆ parentJob()

Job * Job::parentJob ( ) const

Returns the parent job, if there is one.

Returns: the parent job, or nullptr if there is none

See also: setParentJob

Definition at line 200 of file job.cpp.

◆ queryMetaData()

QString Job::queryMetaData ( const QString & key )

Query meta data received from the worker.

(Valid when first data is received and/or worker is finished)

Parameters

key	the key of the meta data to retrieve

Returns: the value of the meta data, or QString() if the key does not exist

Definition at line 210 of file job.cpp.

◆ removeSubjob()

bool Job::removeSubjob ( KJob * job )

overrideprotectedvirtual

Mark a sub job as being done.

Note that this does not terminate the parent job, even if job is the last subjob. emitResult must be called to indicate that the job is complete.

Parameters

job	the subjob to remove

Reimplemented from KCompositeJob.

Definition at line 80 of file job.cpp.

◆ setMetaData()

void Job::setMetaData ( const KIO::MetaData & metaData )

Set meta data to be sent to the worker, replacing existing meta data.

Parameters

metaData the meta data to set

See also: addMetaData(); mergeMetaData()

Definition at line 215 of file job.cpp.

◆ setParentJob()

void Job::setParentJob ( Job * parentJob )

Set the parent Job.

One example use of this is when FileCopyJob calls RenameDialog::open, it must pass the correct progress ID of the parent CopyJob (to hide the progress dialog). You can set the parent job only once. By default a job does not have a parent job.

Parameters

parentJob the new parent job

Definition at line 192 of file job.cpp.

◆ setUiDelegateExtension()

void Job::setUiDelegateExtension ( JobUiDelegateExtension * extension )

Sets the UI delegate extension to be used by this job.

The default UI delegate extension is KIO::defaultJobUiDelegateExtension()

Definition at line 50 of file job.cpp.

◆ start()

void KIO::Job::start ( )

inlineoverridevirtual

Implements KJob.

Definition at line 55 of file job_base.h.

◆ uiDelegateExtension()

JobUiDelegateExtension * Job::uiDelegateExtension ( ) const

Retrieves the UI delegate extension used by this job.

Since: 5.0

Definition at line 44 of file job.cpp.
