For all jobs created in an application, the code looks like
TDEIO::Job * job = TDEIO::someoperation( some parameters );
(other connects, specific to the job)
And slotResult is usually at least:

Add key/value pair to the meta data that is sent to the slave.
- Parameters
-
key | the key of the meta data |
value | the value of the meta data |
- See also
- setMetaData()
-

void Job::addMetaData |
( |
const TQMap< TQString, TQString > & |

|
Add key/value pairs to the meta data that is sent to the slave.
If a certain key already existed, it will be overridden.
- Parameters

void Job::addSubjob |
( |
Job * |
job, |
|
|
bool |
inheritMetaData = true |
|
) |
| |
|
protectedvirtual |
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.
- Parameters
-
job | the subjob to add |
inheritMetaData | if true, the subjob will inherit the meta data from this job. |
Definition at line 162 of file job.cpp.
- Deprecated:
- .
Don't use ! Emitted when the job is canceled. Signal result() is emitted as well, and error() is, in this case, ERR_USER_CANCELED.
- Parameters
-
job | the job that emitted this 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).
- Parameters
-
job | the job that emitted this signal |

reqUrl | the request URL that generated this error message |
method | the method that generated this error message (unimplemented) |
- Returns
- the following strings: caption, error + description, causes+solutions
Definition at line 478 of file global.cpp.
Utility function for inherited jobs.
Emits the percent signal if bigger than m_percent, after calculating it from the parameters.
- Parameters

totalSize | the total size in bytes |
Definition at line 200 of file job.cpp.

TDEIO_EXPORT TQString TDEIO::Job::errorString |
( |
| ) |
const |
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 Job::showErrorDialog. 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
Definition at line 225 of file global.cpp.
const TQString& TDEIO::Job::errorText |
( |
| ) |
const |
|
inline |
Returns the error text if there has been an error.
Only call if error is not 0. This is really internal, better use errorString() or errorDialog().
- Returns
- a string to help understand the error, usually the url related to the error. Only valid if error() is not 0.
