* This method creates and returns a KParts part from a serviceType (e.g. a mimetype).

* \code

* QString mimetype = KMimeType::findByURL( url )->name();

* if ( part ) {

* part->widget()->show(); // also insert the widget into a layout, or simply use a KVBox as parentWidget
* }
* \endcode
*
* @deprecated use KMimeTypeTrader::createPartInstanceFromQuery instead
*
* @param mimeType the mimetype which this part is associated with
* @param constraint an optional constraint to pass to the trader (see KTrader)
* @param parentWidget the parent widget, will be set as the parent of the part's widget
* @param parent the parent object for the part itself
* @param args A list of string arguments, passed to the factory and possibly
* to the component (see KLibFactory)
* @param error The int passed here will receive an error code in case of errors.
* (See enum KLibLoader::ComponentLoadingError)
