Detailed Description

A generic factory object to create a Part.

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

createObject()

TQObject * Factory::createObject ( TQObject *  parent = 0, const char *  name = 0, const char *  classname = "TQObject", const TQStringList &  args = TQStringList()  )

protectedvirtual

Reimplemented from KLibFactory.

Calls createPart()

Implements KLibFactory.

createPart()

Part * Factory::createPart	(	TQWidget *	parentWidget = 0,
		const char *	widgetName = 0,
		TQObject *	parent = 0,
		const char *	name = 0,
		const char *	classname = "KParts::Part",
		const TQStringList &	args = TQStringList()
	)

Creates a part.

The TQStringList 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. tdehtml. You can for example embed 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, name, parentObject, parentName, "KParts::Part",
            TQStringList("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()

Part * Factory::createPartObject ( TQWidget *  parentWidget = 0, const char *  widgetName = 0, TQObject *  parent = 0, const char *  name = 0, const char *  classname = "KParts::Part", const TQStringList &  args = TQStringList()  )

Reimplement this method in your implementation to create the Part.

The TQStringList 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. tdehtml. 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, name, parentObject, parentName, "Kparts::Part",
            TQStringList("name1="value1"", "name2="value2") );

Returns

the newly created part.

Implemented in KParts::GenericFactory< T >.

partInstance()

const TDEInstance * Factory::partInstance

(

)

If you have a part contained in a shared library you might want to query for meta-information like the about-data, or the TDEInstance 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.

Definition at line 50 of file factory.cpp.

partInstanceFromLibrary()

const TDEInstance * Factory::partInstanceFromLibrary ( const TQCString &  libraryName )

static

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

Parameters

libraryName

name of the library to query the instance from
