## Known Implementations

AtkText is implemented by AtkNoOpObject.

## Description

AtkText should be implemented by AtkObjects on behalf of widgets that have text content which is either attributed or otherwise non-trivial. AtkObjects whose text content is simple, unattributed, and very brief may expose that content via atk_object_get_name instead; however if the text is editable, multi-line, typically longer than three or four words, attributed, selectable, or if the object already uses the 'name' ATK property for other information, the AtkText interface should be used to expose the text content. In the case of editable text content, AtkEditableText (a subtype of the AtkText interface) should be implemented instead.

AtkText provides not only traversal facilities and change notification for text content, but also caret tracking and glyph bounding box calculations. Note that the text strings are exposed as UTF-8, and are therefore potentially multi-byte, and caret-to-byte offset mapping makes no assumptions about the character length; also bounding box glyph-to-offset mapping may be complex for languages which use ligatures.

### The `“text-attributes-changed”` signal

    void
    user_function (AtkText *atktext,

The "text-attributes-changed" signal is emitted when the text attributes of the text of an object which implements AtkText changes.

#### Parameters

atktext | the object which received the signal. |
user_data | user data set when the signal handler was connected. |

Flags: Run Last

### The `“text-caret-moved”` signal

    void
    user_function (AtkText *atktext,
                   gint     arg1,

arg1 | The new position of the text caret. |
user_data | user data set when the signal handler was connected. |

Flags: Run Last

### The `“text-changed”` signal

                   gint     arg2,
                   gpointer user_data)

The "text-changed" signal is emitted when the text of the object which implements the AtkText interface changes, This signal will have a detail which is either "insert" or "delete" which identifies whether the text change was an insertion or a deletion.

`AtkText::text-changed` has been deprecated since version 2.9.4 and should not be used in newly-written code.

Use “text-insert” or “text-remove” instead.

#### Parameters

atktext | the object which received the signal. |
arg1 | The position (character offset) of the insertion or deletion. |
arg2 | The length (in characters) of text inserted or deleted. |
