    ╰── AtkDocument

Known Implementations

AtkDocument is implemented by AtkNoOpObject.

Description

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.

Functions

atk_document_get_document_type ()

const gchar *
atk_document_get_document_type (AtkDocument *document);

atk_document_get_document_type is deprecated and should not be used in newly-written code.

Since 2.12. Please use atk_document_get_attributes() to ask for the document type if it applies.

Gets a string indicating the document type.

Parameters

document

a GObject instance that implements AtkDocumentIface

 

Returns

a string indicating the document type


atk_document_get_document ()

gpointer
atk_document_get_document (AtkDocument *document);

atk_document_get_document is deprecated and should not be used in newly-written code.

Since 2.12. document is already a representation of the document. Use it directly, or one of its children, as an instance of the DOM.

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.

Parameters

document

a GObject instance that implements AtkDocumentIface

 

Returns

a gpointer that points to an instance of the DOM.

Parameters

document

a GObject instance that implements AtkDocumentIface

atk_document_get_page_count ()

gint
atk_document_get_page_count (AtkDocument *document);

Signal Details

The “load-complete” signal

void
user_function (AtkDocument *atkdocument,
               gpointer     user_data)

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.)

Parameters

atkdocument

the object which received the signal.

 

user_data

user data set when the signal handler was connected.

 

Flags: Run Last


The “load-stopped” signal

void
user_function (AtkDocument *atkdocument,
               gpointer     user_data)

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.

Parameters

atkdocument

the object which received the signal.

 

user_data

user data set when the signal handler was connected.

 

Flags: Run Last


The “page-changed” signal

void
user_function (AtkDocument *atkdocument,
               gint         page_number,
               gpointer     user_data)

The 'page-changed' signal is emitted when the current page of a document changes, e.g. pressing page up/down in a document viewer.

Parameters

atkdocument

the object on which the signal was emitted

 

page_number

the new page number. If this value is unknown or not applicable, -1 should be provided.

 

user_data

user data set when the signal handler was connected.

 

Flags: Run Last

Since: 2.12


The “reload” signal

void
user_function (AtkDocument *atkdocument,
               gpointer     user_data)

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.

Parameters

atkdocument

the object which received the signal.

 

user_data

user data set when the signal handler was connected.

 

Flags: Run Last
