An inconsistent GtkToggleButton is an example of an object which is sensitive but not enabled. + *@ATK_STATE_ENABLED: Indicates that this object is enabled, i.e. that it currently reflects some 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. + *@ATK_STATE_SHOWING: 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. *@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_STALE: 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). + *@ATK_STATE_TRANSIENT: 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. *@ATK_STATE_VERTICAL: Indicates the orientation of this object is vertical - *@ATK_STATE_VISIBLE: Indicates this object is visible + *@ATK_STATE_VISIBLE: Indicates this object is visible, e.g. has been explicitly marked for exposure to the user. + * @note: STATE_VISIBLE 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 STATE_VISIBLE and STATE_SHOWING. + * The absence of STATE_VISIBLE and STATE_SHOWING is semantically equivalent to saying + * that an object is 'hidden'. See also STATE_TRUNCATED, which applies if a VISIBLE and SHOWING object + * 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. *@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. + * 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. *@ATK_STATE_INDETERMINATE: Indicates that a check box is in a state other than checked or not checked. + * This usually means that the boolean value reflected or + * controlled by the object does not apply consistently to the entire current context. + * For example, a checkbox for the "Bold" attribute of text may have STATE_INDETERMINATE + * if the currently selected text contains a mixture of weight attributes. + * In many cases interacting with a STATE_INDETERMINATE object will cause + * the context's corresponding boolean attribute to be homogenized, whereupon the object + * will lose STATE_INDETERMINATE and a corresponding state-changed event will be fired. *@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_SUPPORTS_AUTOCOMPLETION: 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 @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_DEFAULT: 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. *@ATK_STATE_ANIMATED: 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. *@ATK_STATE_VISITED: Indicates that the object (typically a hyperlink) has already been 'activated', and/or its backing data has already been downloaded, rendered, or otherwise "visited". *@ATK_STATE_LAST_DEFINED: Not a valid state, used for finding end of enumeration * |
