KDE 4.1 PyKDE API Reference
KService Class Reference
from PyKDE4.kdecore import *
Inherits: KSycocaEntry
Detailed Description
Represent a service, like an application or plugin bound to one or several mimetypes (or servicetypes) as written in its desktop entry file.
The starting point you need is often the static methods, like createInstance(). The types of service a plugin provides is taken from the accompanying desktop file where the 'ServiceTypes=' field is used.
For a tutorial on how to build a plugin-loading mechanism and how to write plugins in general, see http://developer.kde.org/documentation/tutorials/developing-a-plugin-structure/index.html#developing_plugins (todo: port to kde4, create techbase article)

Construct a temporary service with a given name, exec-line and icon.
- Parameters:
-
name the name of the service exec the executable icon the name of the icon
| __init__ | ( | self, | ||
| QString | fullpath | |||
| ) |
Construct a service and take all information from a config file.
- Parameters:
-
fullpath Full path to the config file.
| __init__ | ( | self, | ||
| KDesktopFile | config | |||
| ) |
Construct a service and take all information from a desktop file.
- Parameters:

( | self ) |
| [KServiceAction] actions | ( | self ) |
Returns the actions defined in this desktop file
| KService.List allServices | ( | ) |
Returns the whole list of services.
Useful for being able to to display them in a list box, for example. More memory consuming than the ones above, don't use unless really necessary.
- Returns:
- the list of all services
| bool allowAsDefault | ( | self ) |
Set to true if it is allowed to use this service as the default (main) action for the files it supports (e.g. Left Click in a file manager, or KRun in general).
If not, then this service is only available in RMB popups, so it must be selected explicitly by the user in order to be used. Note that servicemenus supersede this functionality though, at least in konqueror.
- Returns:
- true if the service may be used as the default (main) handler
| bool allowMultipleFiles | ( | self ) |
Checks whether this service can handle several files as startup arguments.
- Returns:
- true if multiple files may be passed to this service at startup. False if only one file at a time may be passed.
| QStringList categories | ( | self ) |
Returns a list of VFolder categories.
- Returns:
- the list of VFolder categories
| QString comment | ( | self ) |
Returns the descriptive comment for the service, if there is one.
- Returns:
- the descriptive comment for the service, or QString() if not set
| KService.DBusStartupType dbusStartupType | ( | self ) |
Returns the DBUSStartupType supported by this service.
- Returns:
- the DBUSStartupType supported by this service
| QString desktopEntryName | ( | self ) |
Returns the filename of the service desktop entry without any extension. E.g. "kppp"
- Returns:
- the name of the desktop entry without path or extension, or QString() if not set
| QString desktopEntryPath | ( | self ) |
Returns the path to the location where the service desktop entry is stored.
This is a relative path if the desktop entry was found in any of the locations pointed to by $KDEDIRS (e.g. "Internet/kppp.desktop") It is a full path if the desktop entry originates from another location.
- Deprecated:
- use entryPath() instead
- Returns:
- the path of the service's desktop file, or QString() if not set
| QString exec_ | ( | self ) |
Returns the executable.
- Returns:
- the command that the service executes, or QString() if not set

- the generic name, or QString() if not set
| bool hasMimeType | ( | self, | ||
| KServiceType | mimeTypePtr | |||
| ) |
Checks whether the mime supports this mime type
- Parameters:
-
mimeTypePtr The name of the mime type you are interested in determining whether this service supports.
Note that if you only have the name of the mime type, you have to look it up with KMimeType.mimeType( mimetype ) and use .data() on the result (this is because KService doesn't know KMimeType for dependency reasons)
Warning this method will fail to return true if this KService isn't from ksycoca (i.e. it was created with a full path or a KDesktopFile) *and* the mimetype isn't explicited listed in the .desktop file but a parent mimetype is. For this reason you should generally get KServices with KMimeTypeTrader or one of the KService.serviceBy methods.
- Returns:
- true if the mime type you specified is supported, otherwise false.
| bool hasServiceType | ( | self, | ||
| QString | serviceTypePtr | |||
| ) |
Checks whether the service supports this service type
- Parameters:
-
serviceTypePtr The name of the service type you are interested in determining whether this service supports.
- Returns:
- true if the service type you specified is supported, otherwise false.
| QString icon | ( | self ) |
Returns the name of the icon.
- Returns:
- the icon associated with the service, or QString() if not set
| int initialPreference | ( | self ) |
What preference to associate with this service initially (before the user has had any chance to define a profile for it). The bigger the value, the most preferred the service is.
- Returns:
- the service preference level of the service
| bool isApplication | ( | self ) |
Services are either applications (executables) or dlopened libraries (plugins).
- Returns:
- true if this service is an application, i.e. it has Type=Application in its .desktop file and exec() will not be empty.

| QString | menuId=0, | |||
| QStringList | reservedMenuIds=0 | |||
| ) |
Returns a path that can be used to create a new KService based on suggestedName.

| KService.Ptr serviceByDesktopName | ( | QString | _name | |
| ) |
Find a service by the name of its desktop file, not depending on its actual location (as long as it's under the applnk or service directories). For instance "konqbrowser" or "kcookiejar". Note that the ".desktop" extension is implicit.
This is the recommended method (safe even if the user moves stuff) but note that it assumes that no two entries have the same filename.
- Parameters:
-
_name the name of the configuration file
- Returns:
- a pointer to the requested service or 0 if the service is unknown.
| KService.Ptr serviceByDesktopPath | ( | QString | _path | |
| ) |
Find a service based on its path as returned by entryPath(). It's usually better to use serviceByStorageId() instead.
- Parameters:
-
_path the path of the configuration file
- Returns:
- a pointer to the requested service or 0 if the service is unknown.
| KService.Ptr serviceByMenuId | ( | QString | _menuId | |
| ) |
Find a service by its menu-id
- Parameters:
-
_menuId the menu id of the service
- Returns:
- a pointer to the requested service or 0 if the service is unknown.
| KService.Ptr serviceByName | ( | QString | _name | |
| ) |
Find a service by name, i.e. the translated Name field. You should never use this method with a literal name as argument, since the name is translated Name field of the desktop file. See serviceByStorageId instead.
- Parameters:
-
_name the name to search
- Returns:
- a pointer to the requested service or 0 if the service is unknown.
| KService.Ptr serviceByStorageId | ( | QString | _storageId | |
| ) |
Find a service by its storage-id or desktop-file path. This function will try very hard to find a matching service.
- Parameters:
-
_storageId the storage id or desktop-file path of the service
- Returns:
- a pointer to the requested service or 0 if the service is unknown.
| QStringList serviceTypes | ( | self ) |
Returns the service types that this service supports.
- Returns:
- the list of service types that are supported Note that this doesn't include inherited servicetypes or mimetypes, only the service types listed in the .desktop file.
