## Detailed Description

This is a convenience class for KService.

You can use it if you have a KService describing a KDataTool. In this case the KDataToolInfo class is more convenient to work with.

Especially useful is the method createTool which creates the datatool described by the service.

KDataToolInfo::KDataToolInfo | ( | const KService::Ptr & | service,
|  | KInstance * | instance
| ) |

Create a valid KDataToolInfo.

Parameters:

  | service | the corresponding service
  | instance | the instance to use

## Member Function Documentation

KDataToolInfo & KDataToolInfo::operator= | ( | const KDataToolInfo & | info | ) |

| Assignment operator. Definition at line 62 of file kdatatool.cpp.

QString KDataToolInfo::dataType | ( |  | ) | const

Returns the data type that the DataTool can accept.

Returns:
  the C++ data type that this DataTool accepts. For example "QString" or "QImage" or something more complicated.

Definition at line 69 of file kdatatool.cpp.

QStringList KDataToolInfo::mimeTypes | ( |  | ) | const

Returns a list of mime type that will be accepted by the DataTool.

The mimetypes are only used if the dataType can be used to store different mimetypes. For example in a "QString" you could save "text/plain" or "text/html" or "text/xml".

Returns:
  the mime types accepted by this DataTool. For example "image/gif" or "text/plain". In some cases the dataType determines the accepted type of data perfectly. In this cases this list may be empty.

Definition at line 77 of file kdatatool.cpp.

bool KDataToolInfo::isReadOnly | ( |  | ) | const

Checks whether the DataTool is read-only.

Returns:
  true if the DataTool does not modify the data passed to it by KDataTool::run.

Definition at line 85 of file kdatatool.cpp.

QPixmap KDataToolInfo::icon | ( |  | ) | const

Returns the icon of this data tool.

Returns:
  a large pixmap for the DataTool.

Deprecated:
  , use iconName()

Definition at line 93 of file kdatatool.cpp.

References KGlobal::dirs(), QPixmap::load(), and KStandardDirs::resourceDirs().

QPixmap KDataToolInfo::miniIcon | ( |  | ) | const

Returns the mini icon of this data tool.

Returns:
  a mini pixmap for the DataTool.

Deprecated:
  , use iconName()

Definition at line 107 of file kdatatool.cpp.

References KGlobal::dirs(), QPixmap::load(), and KStandardDirs::resourceDirs().

QString KDataToolInfo::iconName | ( |  | ) | const

Returns the icon name for this DataTool.

Returns:
  the name of the icon for the DataTool

Definition at line 121 of file kdatatool.cpp.

QStringList KDataToolInfo::userCommands | ( |  | ) | const

Returns a list of strings that you can put in a QPopupMenu item, for example to offer the DataTools services to the user.

The returned value is usually something like "Spell checking", "Shrink Image", "Rotate Image" or something like that. This list comes from the Comment field of the tool's desktop file (so that it can be translated).

Each of the strings returned corresponds to a string in the list returned by commands.

Returns:
  a list of strings that you can put in a QPopupMenu item

Definition at line 136 of file kdatatool.cpp.

References QStringList::split().

QStringList KDataToolInfo::commands | ( |  | ) | const

Returns the list of commands the DataTool can execute.

The application passes the command to the KDataTool::run method.

This list comes from the Commands field of the tool's desktop file.

Each of the strings returned corresponds to a string in the list returned by userCommands.

Returns:
  the list of commands the DataTool can execute, suitable for the KDataTool::run method.

Definition at line 128 of file kdatatool.cpp.

KDataTool * KDataToolInfo::createTool | ( | QObject * | parent = `0`,
|  | const char * | name = `0`
| ) | const

Creates the data tool described by this KDataToolInfo.

Parameters:

  | parent | the parent of the QObject (or 0 for parent-less KDataTools)
  | name | the name of the QObject, can be 0

Returns:
  a pointer to the created data tool or 0 on error.

References KLibFactory::create(), KLibLoader::factory(), QObject::inherits(), KLibLoader::self(), and KDataTool::setInstance().

KService::Ptr KDataToolInfo::service | ( |  | ) | const

The KDataToolInfo's service that is represented by this class.

Returns:
  the service

Definition at line 165 of file kdatatool.cpp.

Referenced by KDataToolInfo().

KInstance* KDataToolInfo::instance | ( |  | ) | const`[inline]`

The instance of the service.

Returns:
  the instance

Definition at line 157 of file kdatatool.h.

Referenced by KDataToolInfo(), and query().

bool KDataToolInfo::isValid | ( |  | ) | const

A DataToolInfo may be invalid if the KService passed to its constructor does not feature the service type "KDataTool".

Returns:
  true if valid, false otherwise

Definition at line 216 of file kdatatool.cpp.

QValueList< KDataToolInfo > KDataToolInfo::query | ( | const QString & | datatype,
|  | const QString & | mimetype,
|  | KInstance * | instance
| ) | `[static]`

Queries the KTrader about installed KDataTool implementations.

Parameters:

  | datatype | a type that the application can 'export' to the tools (e.g. QString)
  | mimetype | the mimetype of the data (e.g. text/plain)
  | instance | the application (or the part)'s instance (to check if a tool is excluded from this part, and also used if the tool wants to read its configuration in the app's config file).

Returns:
  the list of results
