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, SIGNAL( result( KIO::Job * ) ), this, SLOT( slotResult( KIO::Job * ) ) ); |
(other connects, specific to the job)
And slotResult is usually at least:
if ( job->error() ) job->showErrorDialog( this or 0L ); |
|
[ protected: ]
|
[virtual]
void |
[virtual]
Abort this job. This kills all subjobs and deletes the job
Parameters:
quietly | if false, Job will emit signal result
and ask kio_uiserver to close the progress window.
quietly is set to true for subjobs. Whether applications
should call with true or false depends on whether they rely
on result being emitted or not.
|
int |
Returns: the error code for this job, 0 if no error Error codes are defined in KIO::Error. Only call this method from the slot connected to result.
int |
Returns: the progress id for this job, as returned by uiserver
const QString & |
Returns: a string to help understand the error, usually the url related to the error. Only call if error is not 0. This is really internal, better use errorString or errorDialog.
QString |
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" ).arg( errortext ); Use this to display the error yourself, but for a dialog box use KIO::ErrorDialog.
void |
Display a dialog box to inform the user of the error given by this job. Only call if error is not 0, and only in the slot connected to result.
Parameters:
parent | the parent widget for the dialog box |
void |
Associate this job with a window given by window
QWidget * |
[const]
Returns the window this job is associated with.
void |
[signal]
Emitted when the job is finished, in any case (completed, canceled, failed...). Use error to know the result.
void |
[signal]
Emitted when the job is canceled.
Signal result
is emitted as well, and error() is,
in this case, ERR_USER_CANCELED.
void |
[signal]
Emitted to display information about this job, as sent by the slave. Examples of message are "Resolving host", "Connecting to host...", etc.
void |
[signal]
Emitted when the slave successfully connected to the host. There is no guarantee the slave will send this, and this is currently unused (in the applications).
void |
[signal]
Progress signal showing the overall progress of the job This is valid for any kind of job, and allows using a a progress bar very easily (see KProgress)
void |
[signal]
Emitted when we know the size of this job (data size for transfers, number of entries for listings).
void |
[signal]
Regularly emitted to show the progress of this job (current data size for transfers, entries listed).
void |
[signal]
Emitted to display information about the speed of this job.
void |
[ protected slots: virtual slot]
Called whenever a subjob finishes. Default implementation checks for errors and propagates to parent job, then calls removeSubjob. Override if you don't want subjobs errors to be propagated.
void |
[ protected slots: slot]
Forward signal from subjob
void |
[ protected slots: slot]
Forward signal from subjob
void |
[ protected slots: slot]
Remove speed information
void |
[ protected: virtual]
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 slave.
void |
[ protected: virtual]
Mark a sub job as being done. If it's the last to wait on the job will emit a result - jobs with two steps might want to override slotResult in order to avoid calling this method.
void |
[ protected: ]
Utility function for inherited jobs. Emits the percent signal if bigger than m_percent, after calculating it from the parameters.
void |
[ protected: ]
Utility function for inherited jobs. Emits the speed signal and starts the timer for removing that info
void |
[ protected: ]
Utility function to emit the result signal, and suicide this job. It first tells the observer to hide the progress dialog for this job.
