Detailed Description

Represent a mime type, like "text/plain", and the data that is associated with it.

The starting point you need is often the static methods.

KMimeType inherits KServiceType because "text/plain" can be used to find services (apps and components) "which can open text/plain".

Member Function Documentation

KMimeType::List KMimeType::allMimeTypes ( )

static

Get all the mimetypes.

Useful for showing the list of available mimetypes. More memory consuming than the ones above, don't use unless really necessary.

Returns: the list of all existing KMimeTypes

Definition at line 63 of file kmimetype.cpp.

QStringList KMimeType::allParentMimeTypes ( ) const

Return all parent mimetypes of this mimetype, direct or indirect.

This includes the parent(s) of its parent(s), etc. If this mimetype is an alias, the list also contains the canonical name for this mimetype.

The usual reason to use this method is to look for a setting which is stored per mimetype (like PreviewJob does).

Since: 4.1

Definition at line 586 of file kmimetype.cpp.

QString KMimeType::comment ( const KUrl & url = KUrl() ) const

Returns the descriptive comment associated with the MIME type.

The url argument is unused, but provided so that KMimeType derived classes can use it.

Returns: The descriptive comment associated with the MIME type, if any.

Definition at line 525 of file kmimetype.cpp.

QString KMimeType::defaultMimeType ( )

static

Returns the name of the default mimetype.

Always application/octet-stream, but this method exists for performance purposes.

Returns: the name of the default mime type, always "application/octet-stream"

Definition at line 597 of file kmimetype.cpp.

KMimeType::Ptr KMimeType::defaultMimeTypePtr ( )

static

Returns the default mimetype.

Always application/octet-stream. This can be used to check the result of mimeType(name).

Returns: the "application/octet-stream" mimetype pointer.

Definition at line 43 of file kmimetype.cpp.

QString KMimeType::extractKnownExtension ( const QString & fileName )

static

Determines the extension from a filename (or full path) using the mimetype database.

This allows to extract "tar.bz2" for foo.tar.bz2 but still return "txt" for my.doc.with.dots.txt

Definition at line 354 of file kmimetype.cpp.

QString KMimeType::favIconForUrl ( const KUrl & url )

static

Return the "favicon" (see http://www.favicon.com) for the given url, if available.

Does NOT attempt to download the favicon, it only returns one that is already available.

If unavailable, returns QString().

Parameters

url	the URL of the favicon

Returns: the name of the favicon, or QString()

Definition at line 488 of file kmimetype.cpp.

KMimeType::Ptr KMimeType::findByContent	(	const QByteArray &	data,
		int *	accuracy = `0`
	)

static

Tries to find out the MIME type of a data chunk by looking for certain magic numbers and characteristic strings in it.

Parameters

data	the data to examine
accuracy	If not a null pointer, *accuracy is set to the accuracy of the match (which is in the range 0..100)

Returns: a pointer to the KMimeType. "application/octet-stream" is returned if the type can not be found this way.

Definition at line 361 of file kmimetype.cpp.

KMimeType::Ptr KMimeType::findByContent	(	QIODevice *	device,
		int *	accuracy = `0`
	)

static

Tries to find out the MIME type of a data chunk by looking for certain magic numbers and characteristic strings in it.

Parameters

device	the IO device providing the data to examine
accuracy	If not a null pointer, *accuracy is set to the accuracy of the match (which is in the range 0..100)

Returns: a pointer to the KMimeType. "application/octet-stream" is returned if the type can not be found this way.

Since: 4.4

Definition at line 369 of file kmimetype.cpp.

KMimeType::Ptr KMimeType::findByFileContent	(	const QString &	fileName,
		int *	accuracy = `0`
	)

static

Tries to find out the MIME type of a file by looking for certain magic numbers and characteristic strings in it.

This function is similar to the previous one. Note that the file name is not used for determining the file type, it is just used for loading the file's contents.

Parameters

fileName	the path to the file
accuracy	If not a null pointer, *accuracy is set to the accuracy of the match (which is in the range 0..100)

Returns: a pointer to the KMimeType, or the default mimetype (application/octet-stream) if the file cannot be opened.

Definition at line 375 of file kmimetype.cpp.

KMimeType::Ptr KMimeType::findByNameAndContent	(	const QString &	name,
		const QByteArray &	data,
		mode_t	mode = `0`,
		int *	accuracy = `0`
	)

static

Tries to find out the MIME type of filename/url and a data chunk.

Whether to trust the extension or the data depends on the results of both approaches, and is determined automatically.

This method is useful for instance in the get() method of kioslaves, and anywhere else where a filename is associated with some data which is available immediately.

Parameters

name	the filename or url representing this data. Only used for the extension, not used as a local filename.
data	the data to examine when the extension isn't conclusive in itself
mode	the mode of the file (used, for example, to identify executables)
accuracy	If not a null pointer, *accuracy is set to the accuracy of the match (which is in the range 0..100)

Definition at line 337 of file kmimetype.cpp.

KMimeType::Ptr KMimeType::findByNameAndContent	(	const QString &	name,
		QIODevice *	device,
		mode_t	mode = `0`,
		int *	accuracy = `0`
	)

static

Tries to find out the MIME type of filename/url and a data chunk.

Whether to trust the extension or the data depends on the results of both approaches, and is determined automatically.

This method is useful for instance in the get() method of kioslaves, and anywhere else where a filename is associated with some data which is available immediately.

Parameters

name	the filename or url representing this data. Only used for the extension, not used as a local filename.
device	the IO device providing the data to examine when the extension isn't conclusive in itself
mode	the mode of the file (used, for example, to identify executables)
accuracy	If not a null pointer, *accuracy is set to the accuracy of the match (which is in the range 0..100)

Returns: a pointer to the KMimeType. "application/octet-stream" is returned if the type can not be found this way.

Since: 4.4

Definition at line 346 of file kmimetype.cpp.

KMimeType::Ptr KMimeType::findByPath	(	const QString &	path,
		mode_t	mode = `0`,
		bool	fast_mode = `false`,
		int *	accuracy = `0`
	)

static

Finds a KMimeType with the given url.

This function looks at mode_t first. If that does not help it looks at the extension. This is fine for FTP, FILE, TAR and friends, but is not for HTTP ( cgi scripts! ). You should use KRun instead, but this function returns immediately while KRun is async. If no extension matches, then the file contents will be examined if the URL is a local file, or "application/octet-stream" is returned otherwise.

Equivalent to

KUrl u(path);

return findByUrl( u, mode, true, fast_mode );

Parameters

path	the path to the file (a file name is enough, in fast mode)
mode	the mode of the file (used, for example, to identify executables)
fast_mode	If set to true no disk access is allowed to find out the mimetype. The result may be suboptimal, but it is fast.
accuracy	If not a null pointer, *accuracy is set to the accuracy of the match (which is in the range 0..100)

Returns: A pointer to the matching mimetype. 0 is never returned.

Definition at line 329 of file kmimetype.cpp.

KMimeType::Ptr KMimeType::findByUrl	(	const KUrl &	url,
		mode_t	mode = `0`,
		bool	is_local_file = `false`,
		bool	fast_mode = `false`,
		int *	accuracy = `0`
	)

static

Finds a KMimeType with the given url.

This function looks at mode_t first. If that does not help it looks at the extension (and the contents, for local files). This method is fine for many protocols like ftp, file, fish, zip etc., but is not for http (e.g. cgi scripts make extension-based checking unreliable). For HTTP you should use KRun instead (to open the URL, in an app or internally), or a KIO::mimetype() job (to find the mimetype without downloading), or a KIO::get() job (to find the mimetype and then download). In fact KRun is the most complete solution, but deriving from it just for this is a bit cumbersome.

If no extension matches, then the file contents will be examined if the URL is a local file, or "application/octet-stream" is returned otherwise.

Parameters

url	Is the right most URL with a filesystem protocol. It is up to you to find out about that if you have a nested URL. For example "http://localhost/mist.gz#gzip:/decompress" would have to pass the "http://..." URL part, while "file:/tmp/x.tar#tar:/src/test.gz#gzip:/decompress" would have to pass the "tar:/..." part of the URL, since gzip is a filter protocol and not a filesystem protocol.
mode	the mode of the file (used, for example, to identify executables)
is_local_file	true if the file is local; false if not, or if you don't know.
fast_mode	If set to true no disk access is allowed to find out the mimetype. The result may be suboptimal, but it is fast.
accuracy	if set, the accuracy of the result, between 0 and 100. For instance, when the extension was used to determine the mimetype, the accuracy is set to 80, as per the shared-mime spec. Some 'magic' rules (used when !fast_mode) have an accuracy > 80 (and have priority over the filename, others are < 80).

Returns: A pointer to the matching mimetype. 0 is never returned. Very Important: Don't store the result in a KMimeType* !

Definition at line 316 of file kmimetype.cpp.

QString KMimeType::iconName ( const KUrl & url = KUrl() ) const

Return the filename of the icon associated with the mimetype.

Use KIconLoader::loadMimeTypeIcon to load the icon.

Parameters

url	argument only used for directories, where the icon can be specified in the .directory file.

Returns: The name of the icon associated with this MIME type.

Definition at line 604 of file kmimetype.cpp.

QString KMimeType::iconNameForUrl	(	const KUrl &	url,
		mode_t	mode = `0`
	)

static

Return the filename of the icon associated with the mimetype, for a given url.

Use KIconLoader::loadMimeTypeIcon to load the icon.

Parameters

url	URL for the file
mode	the mode of the file. The mode may modify the icon with overlays that show special properties of the icon. Use 0 for default

Returns: the name of the icon. The name of a default icon if there is no icon for the mime type

Definition at line 460 of file kmimetype.cpp.

bool KMimeType::is ( const QString & mimeTypeName ) const

Do not use name()=="somename" anymore, to check for a given mimetype.

For mimetype inheritance to work, use is("somename") instead. Warning, do not use inherits(), that's the servicetype inheritance concept! is() also supports mimetype aliases.

Definition at line 556 of file kmimetype.cpp.

bool KMimeType::isBinaryData ( const QString & fileName )

static

Returns whether a file has an internal format that is not human readable.

This is much more generic than "not mime->is(text/plain)". Many application file formats (like rtf and postscript) are based on text, but text that the user should rarely ever see.

Definition at line 397 of file kmimetype.cpp.

bool KMimeType::isBufferBinaryData ( const QByteArray & data )

static

Returns whether a buffer has an internal format that is not human readable.

This is much more generic than "not mime->is(text/plain)". Many application file formats (like rtf and postscript) are based on text, but text that the user should rarely ever see.

Definition at line 74 of file kmimetype.cpp.

bool KMimeType::isDefault ( ) const

Return true if this mimetype is the default mimetype.

Definition at line 48 of file kmimetype.cpp.

QString KMimeType::mainExtension ( ) const

Return the primary extension associated with this mimetype, if any.

If patterns() returns (*.jpg, *.jpeg) then mainExtension will return ".jpg". Note that the dot is included.

If none of the patterns is in *.foo format (for instance *.jp? or *.* or callgrind.out* ) then mainExtension() returns an empty string.

Since: 4.3

Definition at line 743 of file kmimetype.cpp.

bool KMimeType::matchFileName	(	const QString &	filename,
		const QString &	pattern
	)

static

Returns true if the given filename matches the given pattern.

Since: 4.6.1

Definition at line 775 of file kmimetype.cpp.

KMimeType::Ptr KMimeType::mimeType	(	const QString &	name,
		FindByNameOption	options = `ResolveAliases`
	)

static

Retrieve a pointer to the mime type name.

Very important: Don't store the result in a KMimeType* !

Also note that you get a new KMimeType pointer every time you call this. Don't ever write code that compares mimetype pointers, compare names instead.

Parameters

name	the name of the mime type
options	controls how the mime type is searched for

Returns: the pointer to the KMimeType with the given name, or 0 if not found

See also: KServiceType::serviceType

Definition at line 58 of file kmimetype.cpp.

QString KMimeType::parentMimeType ( ) const

If this mimetype is a subclass of another mimetype, return the name of the parent.

Returns: the parent mime type, or QString() if not set

Deprecated:: this method does not support multiple inheritance, which is actually part of the shared-mime-info standard. Use is(), parentMimeTypes(), or allParentMimeTypes() instead of parentMimeType()

Definition at line 532 of file kmimetype.cpp.

QStringList KMimeType::parentMimeTypes ( ) const

If this mimetype is a subclass of one or more other mimetypes, return the list of those mimetypes.

For instance a application/javascript is a special kind of text/plain, so the definition of application/javascript says sub-class-of type="text/plain"

Another example: application/x-shellscript is a subclass of two other mimetypes, application/x-executable and text/plain.

(Note that this notion doesn't map to the servicetype inheritance mechanism, since an application that handles the specific type doesn't necessarily handle the base type. The opposite is true though.)

Returns: the list of parent mimetypes

Since: 4.1

Definition at line 565 of file kmimetype.cpp.

QStringList KMimeType::patterns ( ) const

Retrieve the list of patterns associated with the MIME Type.

Returns: a list of file globs that describe the file names (or, usually, the extensions) of files with this mime type

Definition at line 610 of file kmimetype.cpp.

int KMimeType::sharedMimeInfoVersion ( )

static

Returns the version of the installed update-mime-database program (from freedesktop.org shared-mime-info).

This is used by unit tests and by the code that writes out icon definitions.

Since: 4.3

Returns: -1 on error, otherwise a version number to use like this:
if (version >= KDE_MAKE_VERSION(0, 40, 0)) { ... }

Definition at line 738 of file kmimetype.cpp.

QString KMimeType::userSpecifiedIconName ( ) const

Returns the user-specified icon for this mimetype.

This is empty most of the time, you probably want to use iconName() instead. This method is for the mimetype editor.

Since: 4.3

Definition at line 731 of file kmimetype.cpp.
