Class Details¶

class Atk.Text¶

Bases:	`GObject.GInterface`
Structure:	`Atk.TextIface`

Atk.Text should be implemented by Atk.Objects on behalf of widgets that have text content which is either attributed or otherwise non-trivial. Atk.Objects 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 Atk.Text interface should be used to expose the text content. In the case of editable text content, Atk.EditableText (a subtype of the Atk.Text interface) should be implemented instead.

Atk.Text 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.

classmethod free_ranges(ranges)[source]¶

Parameters:	ranges ([`Atk.TextRange`]) – A pointer to an array of `Atk.TextRange` which is to be freed.

Frees the memory associated with an array of Atk.TextRange. It is assumed that the array was returned by the function Atk.Text.get_bounded_ranges and is None terminated.

Contrary to atk_text_set_position, this does not actually move text in its parent, this only makes the parents scroll so that the object shows up on the screen, given its current position within the parents.

New in version 2.32.

do_scroll_substring_to_point(start_offset, end_offset, coords, x, y) virtual¶

Parameters:	start_offset (`int`) – start position end_offset (`int`) – end position, or -1 for the end of the string. coords (`Atk.CoordType`) – specify whether coordinates are relative to the screen or to the parent object. x (`int`) – x-position where to scroll to y (`int`) – y-position where to scroll to
Returns:	whether scrolling was successful.
Return type:	`bool`

Makes an object visible on the screen at a given position by scrolling all necessary parents.

New in version 2.32.

do_set_caret_offset(offset) virtual¶

Parameters:	offset (`int`) – the character offset of the new caret position
Returns:	`True` if successful, `False` otherwise.
Return type:	`bool`

Sets the caret (cursor) position to the specified offset.

do_set_selection(selection_num, start_offset, end_offset) virtual¶

Parameters:	selection_num (`int`) – The selection number. The selected regions are assigned numbers that correspond to how far the region is from the start of the text. The selected region closest to the beginning of the text region is assigned the number 0, etc. Note that adding, moving or deleting a selected region can change the numbering. start_offset (`int`) – the new starting character offset of the selection end_offset (`int`) – the new end position of (e.g. offset immediately past) the selection
Returns:	`True` if successful, `False` otherwise
Return type:	`bool`

Changes the start and end offset of the specified selection.

do_text_attributes_changed() virtual¶

do_text_caret_moved(location) virtual¶

Parameters:	location (`int`) –

do_text_changed(position, length) virtual¶

Parameters:	position (`int`) – length (`int`) –

do_text_selection_changed() virtual¶

Signal Details¶

Atk.Text.signals.text_attributes_changed(text)¶

Signal Name:	`text-attributes-changed`
Flags:	`RUN_LAST`
Parameters:	text (`Atk.Text`) – The object which received the signal

The “text-attributes-changed” signal is emitted when the text attributes of the text of an object which implements Atk.Text changes.

Atk.Text.signals.text_caret_moved(text, arg1)¶

Signal Name:	`text-caret-moved`
Flags:	`RUN_LAST`
Parameters:	text (`Atk.Text`) – The object which received the signal arg1 (`int`) – The new position of the text caret.

The “text-caret-moved” signal is emitted when the caret position of the text of an object which implements Atk.Text changes.

Atk.Text.signals.text_changed(text, arg1, arg2)¶

Signal Name:	`text-changed`
Flags:	`RUN_LAST`, `DETAILED`
Parameters:	text (`Atk.Text`) – The object which received the signal arg1 (`int`) – The position (character offset) of the insertion or deletion. arg2 (`int`) – The length (in characters) of text inserted or deleted.

The “text-changed” signal is emitted when the text of the object which implements the Atk.Text 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.

Deprecated since version 2.9.4: Use Atk.Object ::text-insert or Atk.Object ::text-remove instead.

Atk.Text.signals.text_insert(text, arg1, arg2, arg3)¶

Signal Name:	`text-insert`
Flags:	`RUN_LAST`, `DETAILED`
Parameters:	text (`Atk.Text`) – The object which received the signal arg1 (`int`) – The position (character offset) of the insertion. arg2 (`int`) – The length (in characters) of text inserted. arg3 (`str`) – The new text inserted

The “text-insert” signal is emitted when a new text is inserted. If the signal was not triggered by the user (e.g. typing or pasting text), the “system” detail should be included.

Atk.Text.signals.text_remove(text, arg1, arg2, arg3)¶

Signal Name:	`text-remove`
Flags:	`RUN_LAST`, `DETAILED`
Parameters:	text (`Atk.Text`) – The object which received the signal arg1 (`int`) – The position (character offset) of the removal. arg2 (`int`) – The length (in characters) of text removed. arg3 (`str`) – The old text removed

The “text-remove” signal is emitted when a new text is removed. If the signal was not triggered by the user (e.g. typing or pasting text), the “system” detail should be included.

Atk.Text.signals.text_selection_changed(text)¶

Signal Name:	`text-selection-changed`
Flags:	`RUN_LAST`
Parameters:	text (`Atk.Text`) – The object which received the signal

The “text-selection-changed” signal is emitted when the selected text of an object which implements Atk.Text changes.
