# class Factory

### abstract

Module | kparts
Namespace | KParts
Class | Factory
Inherits | KLibFactory

A generic factory object to create a Part.

Factory is an abstract class. Reimplement the createPartObject() method to give it functionality.

See also KLibFactory.

### methods

- Factory (parent)

  returns ctor

  Argument | Type | Default
  --- | --- | ---
  parent | QObject | 0

- createObject (parent, classname, args)

  returns QObject

  Argument | Type | Default
  --- | --- | ---
  parent | QObject | 0
  classname | char | "QObject"
  args | QStringList | QStringList()

  Reimplemented from KLibFactory. Calls createPart()

- createPart (parentWidget, parent, classname, args)

  returns KParts.Part

  Argument | Type | Default
  --- | --- | ---
  parentWidget | QWidget | 0
  parent | QObject | 0
  classname | char | "KParts.Part"
  args | QStringList | QStringList()

  Creates a part.

  The QStringList can be used to pass additional arguments to the part. If the part needs additional arguments, it should take them as name="value" pairs. This is the way additional arguments will get passed to the part from eg. khtml. You can for example emebed the part into HTML by using the following code:

  This could result in a call to

      createPart( parentWidget, parentObject, "KParts.Part",
      QStringList("name1="value1"", "name2="value2") );

  Returns the newly created part.

  createPart() automatically emits a signal KLibFactory.objectCreated to tell the library about its newly created object. This is very important for reference counting, and allows unloading the library automatically once all its objects have been destroyed.

- createPartObject (parentWidget, parent, classname, args)

  returns KParts.Part
  pure virtual

  Argument | Type | Default
  --- | --- | ---
  parentWidget | QWidget | 0
  parent | QObject | 0
  classname | char | "KParts.Part"
  args | QStringList | QStringList()

  Reimplement this method in your implementation to create the Part.

  The QStringList can be used to pass additional arguments to the part. If the part needs additional arguments, it should take them as name="value" pairs. This is the way additional arguments will get passed to the part from eg. khtml. You can for example emebed the part into HTML by using the following code:

  This could result in a call to

      createPart( parentWidget, parentObject, "KParts.Part",
      QStringList("name1="value1"", "name2="value2") );

  Returns the newly created part.

- partComponentData ( )

  returns KComponentData

  If you have a part contained in a shared library you might want to query for meta-information like the about-data, or the KComponentData in general. If the part is exported using KParts.GenericFactory then this method will return the instance that belongs to the part without the need to instantiate the part component.

- partComponentDataFromLibrary (libraryName)

  returns KComponentData
  static

  Argument | Type | Default
  --- | --- | ---
  libraryName | QString |

  A convenience method for partComponentData that takes care of retrieving the factory for a given library name and calling partComponentData on it.

  libraryName - name of the library to query the instance from
