AtkDocumentAtkDocument — The ATK interface which represents the toplevel container for document content. |
AtkDocument; const gchar* atk_document_get_document_type (AtkDocument *document); gpointer atk_document_get_document (AtkDocument *document); const gchar* atk_document_get_attribute_value (AtkDocument *document, const gchar *attribute_name); gboolean atk_document_set_attribute_value (AtkDocument *document, const gchar *attribute_name, const gchar *attribute_value); AtkAttributeSet* atk_document_get_attributes (AtkDocument *document); const gchar* atk_document_get_locale (AtkDocument *document);
The AtkDocument interface should be supported by any object whose content is a representation or view of a document. The AtkDocument interface should appear on the toplevel container for the document content; however AtkDocument instances may be nested (i.e. an AtkDocument may be a descendant of another AtkDocument) in those cases where one document contains "embedded content" which can reasonably be considered a document in its own right.
typedef struct _AtkDocument AtkDocument;
The AtkDocument structure does not contain any fields.
const gchar* atk_document_get_document_type (AtkDocument *document);
Gets a string indicating the document type.
document : |
a GObject instance that implements AtkDocumentIface |
Returns : | a string indicating the document type |
gpointer atk_document_get_document (AtkDocument *document);
Gets a gpointer
that points to an instance of the DOM. It is
up to the caller to check atk_document_get_type to determine
how to cast this pointer.
const gchar* atk_document_get_attribute_value (AtkDocument *document, const gchar *attribute_name);
Returns:
document : |
a GObject instance that implements AtkDocumentIface |
attribute_name : |
a character string representing the name of the attribute whose value is being queried. |
Returns : | a string value associated with the named attribute for this document, or NULL if a value for attribute_name has not been specified for this document. |
Since ATK 1.12
gboolean atk_document_set_attribute_value (AtkDocument *document, const gchar *attribute_name, const gchar *attribute_value);
Returns:
document : |
a GObject instance that implements AtkDocumentIface |
attribute_name : |
a character string representing the name of the attribute whose value is being set. |
attribute_value : |
a string value to be associated with attribute_name. |
Returns : | TRUE if value is successfully associated with attribute_name for this document, FALSE otherwise (e.g. if the document does not allow the attribute to be modified). |
Since ATK 1.12
AtkAttributeSet* atk_document_get_attributes (AtkDocument *document);
Gets an AtkAttributeSet which describes document-wide attributes as name-value pairs.
Returns:
document : |
a GObject instance that implements AtkDocumentIface |
Returns : | An AtkAttributeSet containing the explicitly set name-value-pair attributes associated with this document as a whole. |
Since ATK 1.12
const gchar* atk_document_get_locale (AtkDocument *document);
Gets a UTF-8 string indicating the POSIX-style LC_MESSAGES locale of the content of this document instance. Individual text substrings or images within this document may have a different locale, see atk_text_get_attributes and atk_image_get_image_locale.
document : |
a GObject instance that implements AtkDocumentIface |
Returns : | a UTF-8 string indicating the POSIX-style LC_MESSAGES locale of the document content as a whole, or NULL if the document content does not specify a locale. |
"load-complete"
signalvoid user_function (AtkDocument *atkdocument, gpointer user_data) : Run Last
The 'load-complete' signal is emitted when a pending load of a static document has completed. This signal is to be expected by ATK clients if and when AtkDocument implementors expose ATK_STATE_BUSY. If the state of an AtkObject which implements AtkDocument does not include ATK_STATE_BUSY, it should be safe for clients to assume that the AtkDocument's static contents are fully loaded into the container. (Dynamic document contents should be exposed via other signals.)
atkdocument : |
the object which received the signal. |
user_data : |
user data set when the signal handler was connected. |
"load-stopped"
signalvoid user_function (AtkDocument *atkdocument, gpointer user_data) : Run Last
The 'load-stopped' signal is emitted when a pending load of document contents is cancelled, paused, or otherwise interrupted by the user or application logic. It should not however be emitted while waiting for a resource (for instance while blocking on a file or network read) unless a user-significant timeout has occurred.
atkdocument : |
the object which received the signal. |
user_data : |
user data set when the signal handler was connected. |
"reload"
signalvoid user_function (AtkDocument *atkdocument, gpointer user_data) : Run Last
The 'reload' signal is emitted when the contents of a document is refreshed from its source. Once 'reload' has been emitted, a matching 'load-complete' or 'load-stopped' signal should follow, which clients may await before interrogating ATK for the latest document content.
atkdocument : |
the object which received the signal. |
user_data : |
user data set when the signal handler was connected. |
