Enum AccessibleState
The possible states objects in an application UI.
[Flags]
public enum AccessibleStateFields
AlertHigh = 268435456Indicates important information to be immediately conveyed to the user. For example, when a battery reaches a critically low level, a level indicator generates a high-level alert. As a result, a blind access tool immediately announces this information to the user, and a screen magnification program scrolls the screen so that the battery indicator is in view. This state is also appropriate for any prompt or operation that must be completed before the user can continue.
AlertLow = 67108864Indicates low-priority information that is not important to the user. This state is used, for example, when Word changes the appearance of the TipWizard button on its toolbar to indicate that it has a hint for the user.
AlertMedium = 134217728Indicates important information that is not conveyed immediately to the user. For example, when a battery is starting to reach a low level, a level indicator generates a medium-level alert. A blind access tool then generates a sound to let the user know that important information is available, without actually interrupting the user's work. The user could then query the alert information when convenient.
Animated = 16384The object's appearance changes rapidly or constantly. Graphics that are animated occasionally are described as Graphic with the State property set to Animated. This state is used to indicate that the object's location is changing.
Busy = 2048The control cannot accept input at this time.
Checked = 16The object's check box is selected.
Collapsed = 1024The object's children that have the OutlineItem role are hidden.
Default = 256This state represents the default button in a window.
Expanded = 512The object's children that have the OutlineItem role are displayed.
ExtendSelectable = 33554432Indicates that an object extends its selection by using ExtendSelection in the IAccessible::accSelect method.
Floating = 4096The object is not clipped to the boundary of its parent object, and it does not move automatically when the parent moves.
Focusable = 1048576The object is on the active window and is ready to receive keyboard focus.
Focused = 4The object has the keyboard focus. Do not confuse object focus with object selection. For more information, see Selection and Focus Properties and Methods. For objects with this object state, send the EVENT_OBJECT_SHOW or EVENT_OBJECT_HIDE WinEvents to notify client applications about state changes. Do not use EVENT_OBJECT_STATECHANGE.
HotTracked = 128The object is hot-tracked by the mouse, which means that the object's appearance has changed to indicate that the mouse pointer is located over it.
Invisible = 32768The object is programmatically hidden. For example, menu items are programmatically hidden until a user activates the menu. Because objects with this state are not available to users, client applications must not communicate information about the object to users. However, if client applications find an object with this state, they should check whether OffScreen is also set. If this second state is defined, clients can communicate the information about the object to users. For example, a list box can have both Invisible and OffScreen set. In this case, the client application can communicate all items in the list to users. If a client application is navigating through an IAccessible tree and encounters a parent object that is invisible, Microsoft Active Accessibility will not expose information about any possible children of the parent as long as the parent is invisible.
Linked = 4194304Indicates that the object is formatted as a hyperlink. The object's role will usually be Text.
Marqueed = 8192Indicates scrolling or moving text or graphics.
Mixed = 32Indicates that the state of a three-state check box or toolbar button is not determined. The check box is neither selected nor cleared and is therefore in the third or mixed state.
Moveable = 262144Indicates that the object can be moved. For example, a user can click the object's title bar and drag the object to a new location.
MultiSelectable = 16777216Indicates that the object accepts multiple selected items; that is, AddSelection for the IAccessible::accSelect method is valid.
Normal = 0The object has no state or is in a default state.
OffScreen = 65536The object is clipped or has scrolled out of view, but it is not programmatically hidden. If the user makes the viewport larger, more of the object will be visible on the computer screen.
Pressed = 8The object is pressed.
Protected = 536870912The object is a password-protected edit control.
ReadOnly = 64The object is designated read-only.
Selectable = 2097152The object accepts selection.
Selected = 2The object is selected.
SelfVoicing = 524288The object or child uses text-to-speech (TTS) technology for description purposes. When an object with this state has the focus, a speech-based accessibility aid does not announce information because the object automatically announces it.
Sizeable = 131072The object can be resized. For example, a user could change the size of a window by dragging it by the border.
Traversed = 8388608The object is a hyperlink that has been visited (previously clicked) by a user.
The object is unavailable.
