Used by various interfaces indicating every possible state of an accessibility object.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Invalid

Indicates an invalid state - probably an error condition.

Active

Indicates a window is currently the active window, or an object is the active subelement within a container or table.

Active should not be used for objects which have State::Focusable or State::Selectable: Those objects should use State::Focused and State::Selected respectively.

Active is a means to indicate that an object which is not focusable and not selectable is the currently-active item within its parent container.

Armed

Indicates that the object is armed.

Busy

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.

Checked

Indicates this object is currently checked.

Collapsed

Indicates this object is collapsed.

Defunct

Indicates that this object no longer has a valid backing widget (for instance, if its peer object has been destroyed).

Editable

Indicates the user can change the contents of this object.

Enabled

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 Enabled.

See State::Sensitive.

Expandable

Indicates this object allows progressive disclosure of its children.

Expanded

Indicates this object is expanded.

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.

Focused

Indicates this object currently has the keyboard focus.

HasTooltip

Indicates that the object has an associated tooltip.

Horizontal

Indicates the orientation of this object is horizontal.

Iconified

Indicates this object is minimized and is represented only by an icon.

Modal

Indicates something must be done with this object before the user can interact with an object in a different window.

MultiLine

Indicates this (text) object can contain multiple lines of text.

Multiselectable

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.

Opaque

Indicates this object paints every pixel within its rectangular region. It also indicates an alpha value of unity, if it supports alpha blending.

Pressed

Indicates this object is currently pressed.

Resizable

Indicates the size of this object’s size is not fixed.

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.

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.

Sensitive

Indicates this object is sensitive, e.g. to user interaction. 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 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.

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.

SingleLine

Indicates this (text) object can contain only a single line of text.

Stale

Indicates that the information returned for this object may no longer be synchronized with the application state. This can occur if the object has State::Transient, and can also occur towards the end of the object peer’s lifecycle.

Transient

Indicates this object is transient.

Vertical

Indicates the orientation of this object is vertical; for example this state may appear on such objects as scrollbars, text objects (with vertical text flow), separators, etc.

Visible

Indicates this object is visible, e.g. has been explicitly marked for exposure to the user. 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 Visible and State::Showing. The absence of Visible and State::Showing is semantically equivalent to saying that an object is ‘hidden’.

ManagesDescendants

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 ManagesDescendants 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.

Indeterminate

Indicates that a check box or other boolean indicator 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 Indeterminate if the currently selected text contains a mixture of weight attributes. In many cases interacting with a Indeterminate object will cause the context’s corresponding boolean attribute to be homogenized, whereupon the object will lose Indeterminate and a corresponding state-changed event will be fired.

Required

Indicates that user interaction with this object is ‘required’ from the user, for instance before completing the processing of a form.

Truncated

Indicates that an object’s onscreen content is truncated, e.g. a text value in a spreadsheet cell.

Animated

Indicates this object’s visual representation is dynamic, not static. This state may be applied to an object during an animated ‘effect’ and be removed from the object once its visual representation becomes static. 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.

InvalidEntry

This object has indicated 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.

SupportsAutocompletion

This state 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 crate::interface::Interface::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 source.

SelectableText

Indicates that the object in question supports text selection. It should only be exposed on objects which implement the crate::interface::Interface::Text interface, in order to distinguish this state from State::Selectable, which infers that the object in question is a selectable child of an object which implements crate::interface::Interface::Selection. While similar, text selection and subelement selection are distinct operations.

IsDefault

Indicates that the object in question is the ‘default’ interaction object in a dialog, i.e. the one that gets activated if the user presses “Enter” when the dialog is initially posted.

Visited

Indicates that the object (typically a hyperlink) has already been activated or invoked, with the result that some backing data has been downloaded or rendered.

Checkable

Indicates this object has the potential to be checked, such as a checkbox or toggle-able table cell.

HasPopup

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.

ReadOnly

Indicates that an object which is State::Enabled and State::Sensitive has a value which can be read, but not modified, by the user.
