Detailed Description

A generic factory object to create a Part.

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

KPluginFactory.

Member Function Documentation

QObject * Factory::createObject ( QObject parent = nullptr,
const char *  classname = "QObject",
const QStringList args = QStringList() 
)
overrideprotectedvirtual

Reimplemented from KPluginFactory.

Calls createPart()

Reimplemented from KPluginFactory.

Definition at line 75 of file factory.cpp.

Part * Factory::createPart ( QWidget parentWidget = nullptr,
QObject parent = nullptr,
const char *  classname = "KParts::Part",
const QStringList args = 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:

<object type="my_mimetype" data="url_to_my_data">
<param name="name1" value="value1">
<param name="name2" value="value2">
</object>

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 KPluginFactory::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.

Definition at line 41 of file factory.cpp.

Part * Factory::createPartObject ( QWidget parentWidget = nullptr,
QObject parent = nullptr,
const char *  classname = "KParts::Part",
const QStringList args = QStringList() 
)
overrideprotectedpure virtual

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:

<object type="my_mimetype" data="url_to_my_data">
<param name="name1" value="value1">
<param name="name2" value="value2">
</object>

This could result in a call to

createPart( parentWidget, parentObject, "KParts::Part",
QStringList("name1="value1"", "name2="value2") );
Returns
the newly created part.

Reimplemented from KPluginFactory.

Implemented in KParts::GenericFactory< T >.

Definition at line 70 of file factory.cpp.

KComponentData Factory::partComponentData ( )
virtual

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.

Reimplemented in KParts::GenericFactoryBase< T >, and KParts::GenericFactoryBase< T1 >.

Definition at line 50 of file factory.cpp.

KComponentData Factory::partComponentDataFromLibrary ( const QString libraryName)
static

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

Parameters
libraryNamename of the library to query the instance from
