Buttons often enter this state when a pointer click occurs within their bounds, as a precursor to activation. ATK_STATE_ARMED has been deprecated since ATK-2.16 and should not be used in newly-written code.

        {- ^
        Indicates the current object is busy, i.e. onscreen representation is in the process of changing, or the object is temporarily unavailable for interaction due to activity already in progress.  This state may be used by implementors of Document to indicate that content loading is underway.  It also may indicate other \'pending\' conditions; clients may wish to interrogate this object when the ATK_STATE_BUSY flag is removed.

        directly. For an object which is expected to be editable due to its type, but
        which cannot be edited due to the application or platform preventing the user
        from doing so, that object\'s 'GI.Atk.Objects.StateSet.StateSet' should lack ATK_STATE_EDITABLE and
        should contain ATK_STATE_READ_ONLY.
        -}
        | StateTypeEnabled
        {- ^
        Indicates that this object is enabled, i.e. that it currently reflects some application state. Objects that are \"greyed out\" may lack this state, and may lack the STATE_SENSITIVE if direct user interaction cannot cause them to acquire STATE_ENABLED. See also: ATK_STATE_SENSITIVE

        Indicates this object allows more than one of its children to be selected at the same time, or in the case of text objects, that the object supports non-contiguous text selections.
        -}
        | StateTypeOpaque

        {- ^
        Indicates this object is currently pressed.
        -}
        | StateTypeResizable
        {- ^
        Indicates the size of this object is not fixed
        -}
        | StateTypeSelectable
        {- ^
        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
        -}
        | StateTypeSelected
        {- ^
        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
        -}
        | StateTypeSensitive
        {- ^
        Indicates this object is sensitive, e.g. to user interaction.
        STATE_SENSITIVE usually accompanies STATE_ENABLED for user-actionable controls,
        but may be found in the absence of STATE_ENABLED if the current visible state of the
        control is \"disconnected\" from the application state.  In such cases, direct user interaction
        can often result in the object gaining STATE_SENSITIVE, for instance if a user makes
        an explicit selection using an object whose current state is ambiguous or undefined.
        /@see@/ STATE_ENABLED, STATE_INDETERMINATE.
        -}
        | StateTypeShowing
        {- ^
        Indicates this object, the object\'s parent, the object\'s parent\'s parent, and so on,
        are all \'shown\' to the end-user, i.e. subject to \"exposure\" if blocking or obscuring objects do not interpose
        between this object and the top of the window stack.
        -}
        | StateTypeSingleLine
        {- ^
        Indicates this (text) object can contain only a single line of text
        -}
        | StateTypeStale
        {- ^
        Indicates that the information returned for this object may no longer be
        synchronized with the application state.  This is implied if the object has STATE_TRANSIENT,
        and can also occur towards the end of the object peer\'s lifecycle. It can also be used to indicate that
        the index associated with this object has changed since the user accessed the object (in lieu of
        \"index-in-parent-changed\" events).
        -}
        | StateTypeTransient
        {- ^
        Indicates this object is transient, i.e. a snapshot which may not emit events when its
        state changes.  Data from objects with ATK_STATE_TRANSIENT should not be cached, since there may be no
        notification given when the cached data becomes obsolete.
        -}
        | StateTypeVertical
        {- ^
        Indicates the orientation of this object is vertical
        -}
        | StateTypeVisible
        {- ^
        Indicates this object is visible, e.g. has been explicitly marked for exposure to the user.
        **note**: 'GI.Atk.Enums.StateTypeVisible' is no guarantee that the object is actually unobscured on the screen, only
        that it is \'potentially\' visible, barring obstruction, being scrolled or clipped out of the
        field of view, or having an ancestor container that has not yet made visible.
        A widget is potentially onscreen if it has both 'GI.Atk.Enums.StateTypeVisible' and 'GI.Atk.Enums.StateTypeShowing'.
        The absence of 'GI.Atk.Enums.StateTypeVisible' and 'GI.Atk.Enums.StateTypeShowing' is semantically equivalent to saying
        that an object is \'hidden\'.  See also 'GI.Atk.Enums.StateTypeTruncated', which applies if an object with
        'GI.Atk.Enums.StateTypeVisible' and 'GI.Atk.Enums.StateTypeShowing' set lies within a viewport which means that its
        contents are clipped, e.g. a truncated spreadsheet cell or
        an image within a scrolling viewport.  Mostly useful for screen-review and magnification
        algorithms.
        -}
        | StateTypeManagesDescendants
        {- ^
        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.
        The presence of STATE_MANAGES_DESCENDANTS is an indication to the client.
        that the children should not, and need not, be enumerated by the client.
        Objects implementing this state are expected to provide relevant state
        notifications to listening clients, for instance notifications of visibility
        changes and activation of their contained child objects, without the client
        having previously requested references to those children.
        -}
        | StateTypeIndeterminate
        {- ^
        Indicates that the value, or some other quantifiable
        property, of this AtkObject cannot be fully determined. In the case of a large
        data set in which the total number of items in that set is unknown (e.g. 1 of
        999+), implementors should expose the currently-known set size (999) along
        with this state. In the case of a check box, this state should be used to
        indicate that the check box is a tri-state check box which is currently
        neither checked nor unchecked.
        -}
        | StateTypeTruncated
        {- ^
        Indicates that an object is truncated, e.g. a text value in a speradsheet cell.
        -}
        | StateTypeRequired
        {- ^
        Indicates that explicit user interaction with an object is required by the user interface, e.g. a required field in a \"web-form\" interface.
        -}
        | StateTypeInvalidEntry
        {- ^
        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.
        -}
        | StateTypeSupportsAutocompletion
        {- ^
        Indicates that the object in question implements some form of ¨typeahead¨ or
        pre-selection behavior whereby entering the first character of one or more sub-elements
        causes those elements to scroll into view or become selected.  Subsequent character input
        may narrow the selection further as long as one or more sub-elements match the string.
        This state is normally only useful and encountered on objects that implement Selection.
        In some cases the typeahead behavior may result in full or partial ¨completion¨ of
        the data in the input field, in which case these input events may trigger text-changed
        events from the AtkText interface.  This state supplants /@aTKROLEAUTOCOMPLETE@/.
        -}
        | StateTypeSelectableText
        {- ^
        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 /@aTKSTATESELECTABLE@/, 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.
        -}
        | StateTypeDefault
        {- ^
        Indicates that the object is the \"default\" active component, i.e. the object which is activated by an end-user press of the \"Enter\" or \"Return\" key.  Typically a \"close\" or \"submit\" button.
        -}
        | StateTypeAnimated
        {- ^
        Indicates that the object changes its appearance dynamically as an inherent part of its presentation.  This state may come and go if an object is only temporarily animated on the way to a \'final\' onscreen presentation.
        **note**: some applications, notably content viewers, may not be able to detect
        all kinds of animated content.  Therefore the absence of this state should not
        be taken as definitive evidence that the object\'s visual representation is
        static; this state is advisory.
        -}
        | StateTypeVisited
        {- ^
        Indicates that the object (typically a hyperlink) has already been \'activated\', and\/or its backing data has already been downloaded, rendered, or otherwise \"visited\".
        -}
        | StateTypeCheckable
        {- ^
        Indicates this object has the potential to be
         checked, such as a checkbox or toggle-able table cell. /@since@/:
         ATK-2.12
        -}
        | StateTypeHasPopup
        {- ^
        Indicates that the object has a popup context
        menu or sub-level menu which may or may not be showing. This means
        that activation renders conditional content.  Note that ordinary
        tooltips are not considered popups in this context. /@since@/: ATK-2.12
        -}
        | StateTypeHasTooltip
        {- ^
        Indicates this object has a tooltip. /@since@/: ATK-2.16
        -}
        | StateTypeReadOnly
        {- ^
        Indicates that a widget which is ENABLED and SENSITIVE
        has a value which can be read, but not modified, by the user. Note that this
        state should only be applied to widget types whose value is normally directly
        user modifiable, such as check boxes, radio buttons, spin buttons, text input
        fields, and combo boxes, as a means to convey that the expected interaction
        with that widget is not possible. When the expected interaction with a
        widget does not include modification by the user, as is the case with
        labels and containers, ATK_STATE_READ_ONLY should not be applied. See also
        ATK_STATE_EDITABLE. /@since@/: ATK-2-16

        brief amount of information to the user and whose role is known by the
        implementor but lacks semantic value for the user. Examples in which
        'GI.Atk.Enums.RoleStatic' is appropriate include the message displayed in a message box
        and an image used as an alternative means to display text. 'GI.Atk.Enums.RoleStatic'
        should not be applied to widgets which are traditionally interactive, objects
        which display a significant amount of content, or any object which has an
        accessible relation pointing to another object. Implementors should expose the
        displayed information through the accessible name of the object. If doing so seems
        inappropriate, it may indicate that a different role should be used. For
        labels which describe another widget, see 'GI.Atk.Enums.RoleLabel'. For text views, see
        'GI.Atk.Enums.RoleText'. For generic containers, see 'GI.Atk.Enums.RolePanel'. For objects whose
        role is not known by the implementor, see 'GI.Atk.Enums.RoleUnknown'. (Since: 2.16)
