/*******************************************************************************
The following nsIAccessible roles are traslated to ATK_ROLE_UNKNOWN
ROLE_TITLEBAR, ROLE_SOUND, ROLE_CURSOR, ROLE_CARET, ROLE_BORDER,
ROLE_GROUPING, ROLE_EQUATION, ROLE_COLUMN, ROLE_ROW, ROLE_LINK,
ROLE_WHITESPACE, ROLE_CLOCK,
ROLE_IPADDRESS
ROLE_GRIP
The object represents a special mouse pointer, which allows a user to
manipulate user interface elements such as windows.
ROLE_HELPBALLOON
The object displays a Help topic in the form of a ToolTip or Help balloon.
ROLE_PROPERTYPAGE
The object represents a property sheet.
ROLE_INDICATOR
The object represents an indicator, such as a pointer graphic pointing to
the currrent item.
ROLE_HOTKEYFIELD
The object represents a hot-key field that allow the user to enter a
sequence of keystroke.
The following ATK roles have no corresponding nsIAccessible roles. Perhaps
there are not these types of widget/control in Mozilla, so don't need these
ATK roles? Or need add some of them?
ATK_ROLE_ARROW
An arrow in one of the four cardinal directions.
ATK_ROLE_INTERNAL_FRAME
A frame-like object that is clipped by a desktop pane.
ATK_ROLE_ACCEL_LABEL, ATK_ROLE_CANVAS, ATK_ROLE_CHECK_MENU_ITEM,
ATK_ROLE_COLOR_CHOOSER, ATK_ROLE_DATE_EDITOR, ATK_ROLE_DESKTOP_ICON,
ATK_ROLE_DESKTOP_FRAME, ATK_ROLE_DIRECTORY_PANE, ATK_ROLE_FILE_CHOOSER,
ATK_ROLE_FILLER, ATK_ROLE_FONT_CHOOSER, ATK_ROLE_GLASS_PANE,
ATK_ROLE_HTML_CONTAINER, ATK_ROLE_ICON, ATK_ROLE_LAYERED_PANE,
ATK_ROLE_POPUP_MENU, ATK_ROLE_OPTION_PANE, ATK_ROLE_PASSWORD_TEXT,
ATK_ROLE_RADIO_MENU_ITEM, ATK_ROLE_ROOT_PANE, ATK_ROLE_SCROLL_PANE,
ATK_ROLE_SPLIT_PANE, ATK_ROLE_TEAR_OFF_MENU_ITEM, ATK_ROLE_TERMINAL,
ATK_ROLE_TOGGLE_BUTTON, ATK_ROLE_TREE_TABLE, ATK_ROLE_VIEWPORT, ATK_ROLE_LABEL
Important:
Following value should keep synchronization with the definitions in atk.h
