TextT

#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.

Functions

addOnTextAttributesChanged gulong addOnTextAttributesChanged(void delegate(TextIF) dlg, ConnectFlags connectFlags): The "text-attributes-changed" signal is emitted when the text attributes of the text of an object which implements AtkText changes.
addOnTextCaretMoved gulong addOnTextCaretMoved(void delegate(int, TextIF) dlg, ConnectFlags connectFlags): The "text-caret-moved" signal is emitted when the caret position of the text of an object which implements AtkText changes.
addOnTextChanged gulong addOnTextChanged(void delegate(int, int, TextIF) dlg, ConnectFlags connectFlags): 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.
addOnTextInsert gulong addOnTextInsert(void delegate(int, int, string, TextIF) dlg, ConnectFlags connectFlags): 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.
addOnTextRemove gulong addOnTextRemove(void delegate(int, int, string, TextIF) dlg, ConnectFlags connectFlags): 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.
addOnTextSelectionChanged gulong addOnTextSelectionChanged(void delegate(TextIF) dlg, ConnectFlags connectFlags): The "text-selection-changed" signal is emitted when the selected text of an object which implements AtkText changes.
addSelection bool addSelection(int startOffset, int endOffset): Adds a selection bounded by the specified offsets.
getBoundedRanges TextRange[] getBoundedRanges(AtkTextRectangle* rect, AtkCoordType coordType, AtkTextClipType xClipType, AtkTextClipType yClipType): Get the ranges of text in the specified bounding box.
getCaretOffset int getCaretOffset(): Gets the offset of the position of the caret (cursor).
getCharacterAtOffset dchar getCharacterAtOffset(int offset): Gets the specified text.
getCharacterCount int getCharacterCount(): Gets the character count.
getCharacterExtents void getCharacterExtents(int offset, int x, int y, int width, int height, AtkCoordType coords): Get the bounding box containing the glyph representing the character at a particular text offset.
getDefaultAttributes AtkAttributeSet* getDefaultAttributes(): Creates an #AtkAttributeSet which consists of the default values of attributes for the text. See the enum AtkTextAttribute for types of text attributes that can be returned. Note that other attributes may also be returned.
getNSelections int getNSelections(): Gets the number of selected regions.
getOffsetAtPoint int getOffsetAtPoint(int x, int y, AtkCoordType coords): Gets the offset of the character located at coordinates @x and @y. @x and @y are interpreted as being relative to the screen or this widget's window depending on @coords.
getRangeExtents void getRangeExtents(int startOffset, int endOffset, AtkCoordType coordType, AtkTextRectangle rect): Get the bounding box for text within the specified range.
getRunAttributes AtkAttributeSet* getRunAttributes(int offset, int startOffset, int endOffset): Creates an #AtkAttributeSet which consists of the attributes explicitly set at the position @offset in the text. @start_offset and @end_offset are set to the start and end of the range around @offset where the attributes are invariant. Note that @end_offset is the offset of the first character after the range. See the enum AtkTextAttribute for types of text attributes that can be returned. Note that other attributes may also be returned.
getSelection string getSelection(int selectionNum, int startOffset, int endOffset): Gets the text from the specified selection.
getStringAtOffset string getStringAtOffset(int offset, AtkTextGranularity granularity, int startOffset, int endOffset): Gets a portion of the text exposed through an #AtkText according to a given @offset and a specific @granularity, along with the start and end offsets defining the boundaries of such a portion of text.
getText string getText(int startOffset, int endOffset): Gets the specified text.
getTextAfterOffset string getTextAfterOffset(int offset, AtkTextBoundary boundaryType, int startOffset, int endOffset): Gets the specified text.
getTextAtOffset string getTextAtOffset(int offset, AtkTextBoundary boundaryType, int startOffset, int endOffset): Gets the specified text.
getTextBeforeOffset string getTextBeforeOffset(int offset, AtkTextBoundary boundaryType, int startOffset, int endOffset): Gets the specified text.
getTextStruct AtkText* getTextStruct(bool transferOwnership): Get the main Gtk struct
removeSelection bool removeSelection(int selectionNum): Removes the specified selection.
scrollSubstringTo bool scrollSubstringTo(int startOffset, int endOffset, AtkScrollType type): Makes @text visible on the screen by scrolling all necessary parents.
scrollSubstringToPoint bool scrollSubstringToPoint(int startOffset, int endOffset, AtkCoordType coords, int x, int y): Makes an object visible on the screen at a given position by scrolling all necessary parents.
setCaretOffset bool setCaretOffset(int offset): Sets the caret (cursor) position to the specified @offset.
setSelection bool setSelection(int selectionNum, int startOffset, int endOffset): Changes the start and end offset of the specified selection.
