A server interface for screen reader support. Creates a new, empty accessibility element resource. [b]Note:[/b] An accessibility element is created and freed automatically for each [Node]. In general, this function should not be called manually. Creates a new, empty accessibility sub-element resource. Sub-elements can be used to provide accessibility information for objects which are not [Node]s, such as list items, table cells, or menu items. Sub-elements are freed automatically when the parent element is freed, or can be freed early using the [method free_element] method. Creates a new, empty accessibility sub-element from the shaped text buffer. Sub-elements are freed automatically when the parent element is freed, or can be freed early using the [method free_element] method. If [param is_last_line] is [code]true[/code], no trailing newline is appended to the text content. Set to [code]true[/code] for the last line in multi-line text fields and for single-line text fields. Returns the metadata of the accessibility element [param id]. Sets the metadata of the accessibility element [param id] to [param meta]. Frees the accessibility element [param id] created by [method create_element], [method create_sub_element], or [method create_sub_text_edit_elements]. Returns the main accessibility element of the OS native window. Returns [code]true[/code] if [param id] is a valid accessibility element. Returns [code]true[/code] if screen reader is support by this implementation. Sets the window focused state for assistive apps. [b]Note:[/b] This method is implemented on Linux, macOS, and Windows. [b]Note:[/b] Advanced users only! [Window] objects call this method automatically. Sets window outer (with decorations) and inner (without decorations) bounds for assistive apps. [b]Note:[/b] This method is implemented on Linux, macOS, and Windows. [b]Note:[/b] Advanced users only! [Window] objects call this method automatically. Adds a callback for the accessibility action (action which can be performed by using a special screen reader command or buttons on the Braille display), and marks this action as supported. The action callback receives one [Variant] argument, which value depends on action type. Adds a child accessibility element. [b]Note:[/b] [Node] children and sub-elements are added to the child list automatically. Adds support for a custom accessibility action. [param action_id] is passed as an argument to the callback of [constant ACTION_CUSTOM] action. Adds an element that is controlled by this element. Adds an element that describes this element. Adds an element that details this element. Adds an element that this element flow into. Adds an element that labels this element. Adds an element that is part of the same radio group. [b]Note:[/b] This method should be called on each element of the group, using all other elements as [param related_id]. Adds an element that is an active descendant of this element.

Sets text underline/overline/strikethrough. Sets text orientation. Sets text selection to the text field. [param text_start_id] and [param text_end_id] should be elements created by [method create_sub_text_edit_elements]. Character offsets are relative to the corresponding element. Sets tooltip text.
