Detailed Description
Provides the data for the KMetaDataWidget.
The default implementation provides all meta data that are available due to Strigi and Nepomuk. If custom meta data should be added, the method KFileMetaDataProvider::loadData() must be overwritten.

- Returns
- Factory method that returns a widget that should be used to show the meta data represented by
metaDataUri
. If no custom value widget is used for the given URI, the base implementation must be invoked. Per default an instance of QLabel will be returned.
Definition at line 491 of file kfilemetadataprovider.cpp.
- Returns
- Meta data for the items that have been set by KFileMetaDataProvider::setItems(). The method should be invoked after the signal loadingFinished() has been received (otherwise no data will be returned).

Meta data items are sorted alphabetically by their translated label per default.
However it is possible to provide an internal prefix to the label, so that specific items are grouped together. For example it makes sense that the meta data for 'width' and 'height' of an image are shown below each other. By adding a common prefix, a grouping is done.
- Returns
- Returns the name of the group the meta data indicated by
metaDataUri
belongs to. Per default an empty string is returned.

- Returns
- Translated string for the label of the meta data represented by
metaDataUri
. If no custom translation is provided, the base implementation must be invoked.

Is emitted after the loading triggered by KFileMetaDataProvider::setItems() has been finished.
void KFileMetaDataProvider::setItems | ( | const KFileItemList & | items | ) |
Sets the items, where the meta data should be requested.
The loading of the meta data is done asynchronously. The signal loadingFinished() is emitted, as soon as the loading has been finished. The meta data can be retrieved by KFileMetaDataProvider::data() afterwards. The label for each item can be retrieved by KFileMetaDataProvider::label().
Definition at line 388 of file kfilemetadataprovider.cpp.
void KFileMetaDataProvider::setReadOnly | ( | bool | readOnly | ) |
If set to true, data such as the comment, tag or rating cannot be changed by the user.
Per default read-only is disabled. The method readOnlyChanged() can be overwritten to react on the change.
Definition at line 475 of file kfilemetadataprovider.cpp.
