atk Constants the built-in constants of the atk module Synopsis Description Atk Coord Type Constants The Atk Coord Type constants specify how xy coordinates are to be interpreted. Used by methods such as atk.Component.get_position() and atk.Text.get_character_extents() atk.XY_SCREEN specifies xy coordinates relative to the screen atk.XY_WINDOW specifies xy coordinates relative to the widget's top-level window Atk Layer Constants The Atk Layer constants specify the layer of a component. These enumerated "layer values" are used when determining which UI rendering layer a component is drawn into, which can help in making determinations of when components occlude one another. atk.LAYER_INVALID The object does not have a layer atk.LAYER_BACKGROUND This layer is reserved for the desktop background atk.LAYER_CANVAS This layer is used for Canvas components atk.LAYER_WIDGET This layer is normally used for components atk.LAYER_MDI This layer is used for layered components atk.LAYER_POPUP This layer is used for popup components, such as menus atk.LAYER_OVERLAY This layer is reserved for future use. atk.LAYER_WINDOW This layer is used for toplevel windows. Atk Relation Type Constants The Atk Relation Type constants specify the type of the relation. atk.RELATION_NULL Not used, represents "no relationship" or an error condition. atk.RELATION_CONTROLLED_BY Indicates an object controlled by one or more target objects. atk.RELATION_CONTROLLER_FOR Indicates an object is an controller for one or more target objects. atk.RELATION_LABEL_FOR Indicates an object is a label for one or more target objects. atk.RELATION_LABELLED_BY Indicates an object is labelled by one or more target objects. atk.RELATION_MEMBER_OF Indicates an object is a member of a group of one or more target objects. atk.RELATION_NODE_CHILD_OF Indicates an object is a cell in a treetable which is displayed because a cell in the same column is expanded and identifies that cell. atk.RELATION_FLOWS_TO Indicates that the object has content that flows logically to another atk.Object in a sequential way, (for instance text-flow). atk.RELATION_FLOWS_FROM Indicates that the object has content that flows logically from another atk.Object in a sequential way, (for instance text-flow). atk.RELATION_SUBWINDOW_OF Indicates a subwindow attached to a component but otherwise has no connection in the UI hierarchy to that component. atk.RELATION_EMBEDS Indicates that the object visually embeds another object's content, i.e. this object's content flows around another's content. atk.RELATION_EMBEDDED_BY Inverse of atk.RELATION_EMBEDS, indicates that this object's content is visualy embedded in another object. atk.RELATION_POPUP_FOR Indicates that an object is a popup for another object. atk.RELATION_PARENT_WINDOW_OF Indicates that an object is a parent window of another object. atk.RELATION_LAST_DEFINED Not used, this value indicates the end of the enumeration. Atk Role Constants The Atk Role constants describes the role of an object. These are the built-in enumerated roles that UI components can have in ATK. Other roles may be added at runtime, so an AtkRole >= atk.ROLE_LAST_DEFINED is not necessarily an error. atk.ROLE_INVALID Invalid role atk.ROLE_ACCEL_LABEL A label which represents an accelerator atk.ROLE_ALERT An object which is an alert to the user atk.ROLE_ANIMATION An object which is an animated image atk.ROLE_ARROW An arrow in one of the four cardinal directions atk.ROLE_CALENDAR An object that displays a calendar and allows the user to select a date atk.ROLE_CANVAS An object that can be drawn into and is used to trap events atk.ROLE_CHECK_BOX A choice that can be checked or unchecked and provides a separate indicator for the current state atk.ROLE_CHECK_MENU_ITEM A menu item with a check box atk.ROLE_COLOR_CHOOSER A specialized dialog that lets the user choose a color atk.ROLE_COLUMN_HEADER The header for a column of data atk.ROLE_COMBO_BOX A list of choices the user can select from atk.ROLE_DATE_EDITOR An object whose purpose is to allow a user to edit a date atk.ROLE_DESKTOP_ICON An inconifed internal frame within a DESKTOP_PANE atk.ROLE_DESKTOP_FRAME A pane that supports internal frames and iconified versions of those internal frames atk.ROLE_DIAL An object whose purpose is to allow a user to set a value atk.ROLE_DIALOG A top level window with title bar and a border atk.ROLE_DIRECTORY_PANE A pane that allows the user to navigate through and select the contents of a directory atk.ROLE_DRAWING_AREA An object used for drawing custom user interface elements atk.ROLE_FILE_CHOOSER A specialized dialog that lets the user choose a file atk.ROLE_FILLER A object that fills up space in a user interface atk.ROLE_FONT_CHOOSER A specialized dialog that lets the user choose a font atk.ROLE_FRAME A top level window with a title bar, border, menubar, etc. atk.ROLE_GLASS_PANE A pane that is guaranteed to be painted on top of all panes beneath it atk.ROLE_HTML_CONTAINER A document container for HTML, whose children represent the document content atk.ROLE_ICON A small fixed size picture, typically used to decorate components atk.ROLE_IMAGE An object whose primary purpose is to display an image atk.ROLE_INTERNAL_FRAME A frame-like object that is clipped by a desktop pane atk.ROLE_LABEL An object used to present an icon or short string in an interface atk.ROLE_LAYERED_PANE A specialized pane that allows its children to be drawn in layers, providing a form of stacking order atk.ROLE_LIST An object that presents a list of objects to the user and allows the user to select one or more of them atk.ROLE_LIST_ITEM An object that represents an element of a list atk.ROLE_MENU An object usually found inside a menu bar that contains a list of actions the user can choose from atk.ROLE_MENU_BAR An object usually drawn at the top of the primary dialog box of an application that contains a list of menus the user can choose from atk.ROLE_MENU_ITEM An object usually contained in a menu that presents an action the user can choose atk.ROLE_OPTION_PANE A specialized pane whose primary use is inside a DIALOG atk.ROLE_PAGE_TAB An object that is a child of a page tab list atk.ROLE_PAGE_TAB_LIST An object that presents a series of panels (or page tabs), one at a time, through some mechanism provided by the object atk.ROLE_PANEL A generic container that is often used to group objects atk.ROLE_PASSWORD_TEXT A text object uses for passwords, or other places where the text content is not shown visibly to the user atk.ROLE_POPUP_MENU A temporary window that is usually used to offer the user a list of choices, and then hides when the user selects one of those choices atk.ROLE_PROGRESS_BAR An object used to indicate how much of a task has been completed atk.ROLE_PUSH_BUTTON An object the user can manipulate to tell the application to do something atk.ROLE_RADIO_BUTTON A specialized check box that will cause other radio buttons in the same group to become unchecked when this one is checked atk.ROLE_RADIO_MENU_ITEM A check menu item which belongs to a group.

This role is a grouping "hint" indicating that the contained objects share a context. atk.ROLE_ENTRY The object is a component whose textual content may be entered or modified by the user, provided atk.STATE_EDITABLE is present. atk.ROLE_CHART The object is a graphical depiction of quantitative data. It may contain multiple subelements whose attributes and/or description may be queried to obtain both the quantitative data and information about how the data is being presented.

Document frames may occur within another Document instance, in which case the second document may be said to be embedded in the containing instance. HTML frames are often ROLE_DOCUMENT_FRAME. Either this object, or a singleton descendant, should implement the Document interface. atk.ROLE_HEADING The object serves as a heading for content which follows it in a document. The 'heading level' of the heading, if availabe, may be obtained by querying the object's attributes. atk.ROLE_PAGE The object is a containing instance which encapsulates a page of information. atk.ROLE_PAGE is used in documents and content which support a paginated navigation model. atk.ROLE_SECTION The object is a containing instance of document content which constitutes a particular 'logical' section of the document. The type of content within a section, and the nature of the section division itself, may be obtained by querying the object's attributes. Sections may be nested. atk.ROLE_REDUNDANT_OBJECT The object is redundant with another object in the hierarchy, and is exposed for purely technical reasons. Objects of this role should normally be ignored by clients. atk.ROLE_LAST_DEFINED not a valid role, used for finding end of the enumeration Atk State Type Constants The Atk State Type constants specify a particular state of a component. The actual state of an component is described by its atk.StateSet, which is a set of states. atk.STATE_INVALID Indicates an invalid state atk.STATE_ACTIVE Indicates a window is currently the active window atk.STATE_ARMED Indicates that the object is armed. atk.STATE_BUSY Indicates the current object is busy. This state may be used by implementors of Document to indicate that content loading is in process. atk.STATE_CHECKED Indicates this object is currently checked atk.STATE_DEFUNCT Indicates the user interface object corresponding to this object no longer exists atk.STATE_EDITABLE Indicates the user can change the contents of this object atk.STATE_ENABLED Indicates that this object is enabled. An inconsistent gtk.ToggleButton is an example of an object which is sensitive but not enabled. atk.STATE_EXPANDABLE Indicates this object allows progressive disclosure of its children atk.STATE_EXPANDED Indicates this object its expanded atk.STATE_FOCUSABLE Indicates this object can accept keyboard focus, which means all events resulting from typing on the keyboard will normally be passed to it when it has focus atk.STATE_FOCUSED Indicates this object currently has the keyboard focus atk.STATE_HORIZONTAL Indicates the orientation of this object is horizontal atk.STATE_ICONIFIED Indicates this object is minimized and is represented only by an icon atk.STATE_MODAL Indicates something must be done with this object before the user can interact with an object in a different window atk.STATE_MULTI_LINE Indicates this (text) object can contain multiple lines of text atk.STATE_MULTISELECTABLE Indicates this object allows more than one of its children to be selected at the same time atk.STATE_OPAQUE Indicates this object paints every pixel within its rectangular region. atk.STATE_PRESSED Indicates this object is currently pressed atk.STATE_RESIZABLE Indicates the size of this object is not fixed atk.STATE_SELECTABLE Indicates this object is the child of an object that allows its children to be selected and that this child is one of those children that can be selected atk.STATE_SELECTED Indicates this object is the child of an object that allows its children to be selected and that this child is one of those children that has been selected atk.STATE_SENSITIVE Indicates this object is sensitive atk.STATE_SHOWING Indicates this object, the object's parent, the object's parent's parent, and so on, are all visible atk.STATE_SINGLE_LINE Indicates this (text) object can contain only a single line of text atk.STATE_STALE Indicates that the index associated with this object has changed since the user accessed the object. atk.STATE_TRANSIENT Indicates this object is transient atk.STATE_VERTICAL Indicates the orientation of this object is vertical atk.STATE_VISIBLE Indicates this object is visible atk.STATE_MANAGES_DESCENDANTS Indicates that "active-descendant-changed" event is sent when children become 'active' (i.e. are selected or navigated to onscreen). Used to prevent need to enumerate all children in very large containers, like tables. atk.STATE_INDETERMINATE Indicates that a check box is in a state other than checked or not checked. atk.STATE_TRUNCATED Indicates that an object is truncated, e.g. a text value in a speradsheet cell. atk.STATE_REQUIRED Indicates that explicit user interaction with an object is required by the user interface, e.g. a required field in a "web-form" interface. atk.STATE_INVALID_ENTRY Indicates that the object has encountered an error condition due to failure of input validation. For instance, a form control may acquire this state in response to invalid or malformed user input. atk.STATE_SUPPORTS_AUTOCOMPLETION Indicates that the object may exhibit "typeahead" behavior in response to user keystrokes, e.g. one keystroke may result in the insertion of several characters into an entry, or result in the auto-selection of an item in a list. This state supplants atk.ROLE_AUTOCOMPLETE. atk.STATE_SELECTABLE_TEXT Indicates that the object in question supports text selection. It should only be exposed on objects which implement the Text interface, in order to distinguish this state from atk.STATE_SELECTABLE, which infers that the object in question is a selectable child of an object which implements Selection. While similar, text selection and subelement selection are distinct operations. atk.STATE_LAST_DEFINED Not a valid state, used for finding end of enumeration Atk Text Attribute Constants The Atk Text Attribute constants specify the built-in text attributes supported. Other text attributes may be set by an application using the atk.text_attribute_register() function. atk.TEXT_ATTR_INVALID nvalid attribute atk.TEXT_ATTR_LEFT_MARGIN The pixel width of the left margin atk.TEXT_ATTR_RIGHT_MARGIN The pixel width of the right margin atk.TEXT_ATTR_INDENT The number of pixels that the text is indented atk.TEXT_ATTR_INVISIBLE Either "true" or "false" indicating whether text is visible or not atk.TEXT_ATTR_PIXELS_ABOVE_LINES Pixels of blank space to leave above each newline-terminated line. atk.TEXT_ATTR_PIXELS_BELOW_LINES Pixels of blank space to leave below each newline-terminated line. atk.TEXT_ATTR_PIXELS_INSIDE_WRAP Pixels of blank space to leave between wrapped lines inside the same newline-terminated line (paragraph). atk.TEXT_ATTR_BG_FULL_HEIGHT "true" or "false" whether to make the background color for each character the height of the highest font used on the current line, or the height of the font used for the current character. atk.TEXT_ATTR_RISE Number of pixels that the characters are risen above the baseline atk.TEXT_ATTR_UNDERLINE "none", "single", "double" or "low" atk.TEXT_ATTR_STRIKETHROUGH "true" or "false" whether the text is strikethrough atk.TEXT_ATTR_SIZE The size of the characters. atk.TEXT_ATTR_SCALE The scale of the characters.

The value is an RGB value of the format "u,u,u" atk.TEXT_ATTR_FG_COLOR The foreground color. The value is an RGB value of the format "u,u,u" atk.TEXT_ATTR_BG_STIPPLE "true" if a gtk.gdk.Pixmap is set for stippling the background color. atk.TEXT_ATTR_FG_STIPPLE "true" if a gtk.gdk.Pixmap is set for stippling the foreground color. atk.TEXT_ATTR_WRAP_MODE The wrap mode of the text, if any. Values are "none", "char" or "word" atk.TEXT_ATTR_DIRECTION The direction of the text, if set. Values are "none", "ltr" or "rtl" atk.TEXT_ATTR_JUSTIFICATION The justification of the text, if set.

Values are "normal" or "small_caps" atk.TEXT_ATTR_STYLE The slant style of the text, if set. Values are "normal", "oblique" or "italic" atk.TEXT_ATTR_LAST_DEFINED not a valid text attribute, used for finding end of enumeration Atk Text Boundary Constants The Atk Text Boundary constants specify oundaries for regions of text. atk.TEXT_BOUNDARY_CHAR Boundary is the boundary between characters (including non-printing characters) atk.TEXT_BOUNDARY_WORD_START Boundary is the start (i.e. first character) of a word. atk.TEXT_BOUNDARY_WORD_END Boundary is the end (i.e. last character) of a word. atk.TEXT_BOUNDARY_SENTENCE_START Boundary is the first character in a sentence. atk.TEXT_BOUNDARY_SENTENCE_END Boundary is the last (terminal) character in a sentence; in languages which use "sentence stop" punctuation such as English, the boundary is thus the '.', '?', or similar terminal punctuation character. atk.TEXT_BOUNDARY_LINE_START Boundary is the initial character of the content or a character immediately following a newline, linefeed, or return character. atk.TEXT_BOUNDARY_LINE_END Boundary is the linefeed, or return character.
