Functions
Description
A content type is a platform specific string that defines the type of a file. On UNIX it is a mime type like "text/plain" or "image/png". On Win32 it is an extension string like ".doc", ".txt" or a perceived string like "audio". Such strings can be looked up in the registry at HKEY_CLASSES_ROOT. On OSX it is a Uniform Type Identifier such as "com.apple.application".
Functions
g_content_type_equals ()
gboolean g_content_type_equals (const gchar *type1,const gchar *type2);
Compares two content types for equality.
g_content_type_is_a ()
gboolean g_content_type_is_a (const gchar *type,const gchar *supertype);
Determines if type
is a subset of supertype
.
g_content_type_is_mime_type ()
gboolean g_content_type_is_mime_type (const gchar *type,const gchar *mime_type);
Determines if type
is a subset of mime_type
.
Convenience wrapper around g_content_type_is_a().
Since: 2.52
g_content_type_is_unknown ()
gboolean
g_content_type_is_unknown (const gchar *type);
Checks if the content type is the generic "unknown" type. On UNIX this is the "application/octet-stream" mimetype, while on win32 it is "*" and on OSX it is a dynamic type or octet-stream.
g_content_type_get_description ()
gchar *
g_content_type_get_description (const gchar *type);
Gets the human readable description of the content type.
g_content_type_get_mime_type ()
gchar *
g_content_type_get_mime_type (const gchar *type);
Gets the mime type for the content type, if one is registered.
g_content_type_get_icon ()
GIcon *
g_content_type_get_icon (const gchar *type);
Gets the icon for a content type.
Returns
GIcon corresponding to the content type. Free the returned
object with g_object_unref().
[transfer full]
g_content_type_get_symbolic_icon ()
GIcon *
g_content_type_get_symbolic_icon (const gchar *type);
Gets the symbolic icon for a content type.
Returns
symbolic GIcon corresponding to the content type.
Free the returned object with g_object_unref().
[transfer full]
Since: 2.34
g_content_type_get_generic_icon_name ()
gchar *
g_content_type_get_generic_icon_name (const gchar *type);
Gets the generic icon name for a content type.
See the shared-mime-info specification for more on the generic icon name.
Returns
the registered generic icon name for the given type
,
or NULL if unknown. Free with g_free().
[nullable]
Since: 2.34
g_content_type_can_be_executable ()
gboolean
g_content_type_can_be_executable (const gchar *type);
Checks if a content type can be executable. Note that for instance things like text files can be executables (i.e. scripts and batch files).
g_content_type_from_mime_type ()
gchar *
g_content_type_from_mime_type (const gchar *mime_type);
Tries to find a content type based on the mime type name.
Since: 2.18
g_content_type_guess ()
gchar * g_content_type_guess (const gchar *filename,const guchar *data,gsize data_size,gboolean *result_uncertain);
Guesses the content type based on example data. If the function is
uncertain, result_uncertain
will be set to TRUE. Either filename
or data
may be NULL, in which case the guess will be based solely
on the other argument.
g_content_type_guess_for_tree ()
gchar **
g_content_type_guess_for_tree (GFile *root);
Tries to guess the type of the tree with root root
, by
looking at the files it contains. The result is an array
of content types, with the best guess coming first.
The types returned all have the form x-content/foo, e.g. x-content/audio-cdda (for audio CDs) or x-content/image-dcf (for a camera memory card). See the shared-mime-info specification for more on x-content types.
This function is useful in the implementation of
g_mount_guess_content_type().
Returns
an NULL-terminated
array of zero or more content types. Free with g_strfreev().
[transfer full][array zero-terminated=1]
Since: 2.18
g_content_types_get_registered ()
GList *
g_content_types_get_registered (void);
Gets a list of strings containing all the registered content types known to the system. The list and its data should be freed using g_list_free_full (list, g_free).
