\section{\class{wxAccessible}}\label{wxaccessible}

The wxAccessible class allows wxWindows applications, and
wxWindows itself, to return extended information about user interface elements
to client applications such as screen readers. This is the
main way in which wxWindows implements accessibility features.

At present, only Microsoft Active Accessibility is supported
by this class.

To use this class, derive from wxAccessible, implement appropriate
functions, and associate an object of the class with a
window using \helpref{wxWindow::SetAccessible}{wxwindowsetaccessible}.

All functions return an indication of success, failure, or not implemented
using values of the wxAccStatus enum type.

If you return wxACC\_NOT\_IMPLEMENTED from any functioon, the system will try to
implement the appropriate functionality. However this will not work with
all functions.

Most functions work with an {\it object id}, which can be zero to refer to
'this' UI element, or greater than zero to refer to the nth child element.
This allows you to specify elements that don't have a corresponding wxWindow or
wxAccessible; for example, the sash of a splitter window.

For details on the semantics of functions and types, please refer to the
Microsoft Active Accessibility 1.2 documentation.

This class is compiled into wxWindows only if the wxUSE\_ACCESSIBILITY setup
symbol is set to 1.

\wxheading{Data structures}

Functions return a wxAccStatus error code, which
may be one of the following:

{\small \begin{verbatim}
typedef enum
{
    wxACC\_FAIL,             // The function failed
    wxACC\_FALSE,            // The function returned false
    wxACC\_OK,               // The function completed successfully
    wxACC\_NOT\_IMPLEMENTED, // The function is not implemented
    wxACC\_NOT\_SUPPORTED    // The function is not supported
} wxAccStatus
\end{verbatim}}

the following:

{\small \begin{verbatim}

\latexignore{\rtfignore{\wxheading{Members}}}

\membersection{wxAccessible::wxAccessible}\label{wxaccessiblewxaccessible}

\func{}{wxAccessible}{\param{wxWindow* }{win = NULL}}

Constructor, taking an optional window. The object can be associated with
a window later.

\membersection{wxAccessible::\destruct{wxAccessible}}\label{wxaccessibledtor}

\func{}{\destruct{wxAccessible}}{\void}

Destructor.

\membersection{wxAccessible::DoDefaultAction}\label{wxaccessibledodefaultaction}

\func{virtual wxAccStatus}{DoDefaultAction}{\param{int }{childId}}

Performs the default action for the object. {\it childId} is 0 (the action for this object)
or greater than 0 (the action for a child). Return wxACC\_NOT\_SUPPORTED if there
is no default action for this window (e.g. an edit control).

\membersection{wxAccessible::GetChild}\label{wxaccessiblegetchild}

\func{virtual wxAccStatus}{GetChild}{\param{int }{childId}, \param{wxAccessible** }{child}}

Gets the specified child (starting from 1). If {\it child} is NULL and the return value is wxACC\_OK,
this means that the child is a simple element and not an accessible object.

\membersection{wxAccessible::GetChildCount}\label{wxaccessiblegetchildcount}

\func{virtual wxAccStatus}{GetChildCount}{\param{int* }{childCount}}

Returns the number of children in {\it childCount}.

\membersection{wxAccessible::GetDefaultAction}\label{wxaccessiblegetdefaultaction}

\func{virtual wxAccStatus}{GetDefaultAction}{\param{int }{childId}, \param{wxString* }{actionName}}

Gets the default action for this object (0) or a child (greater than 0).
Return wxACC\_OK even if there is no action. {\it actionName} is the action, or the empty
string if there is no action. The retrieved string describes the action that is performed on an object,
not what the object does as a result. For example, a toolbar button that prints
a document has a default action of "Press" rather than "Prints the current document."

\membersection{wxAccessible::GetDescription}\label{wxaccessiblegetdescription}

\func{virtual wxAccStatus}{GetDescription}{\param{int }{childId}, \param{wxString* }{description}}

Returns the description for this object or a child.

\membersection{wxAccessible::GetFocus}\label{wxaccessiblegetfocus}

\func{virtual wxAccStatus}{GetFocus}{\param{int* }{childId}, \param{wxAccessible** }{child}}

Gets the window with the keyboard focus. If childId is 0 and child is NULL, no object in
this subhierarchy has the focus. If this object has the focus, child should be 'this'.

\membersection{wxAccessible::GetHelpText}\label{wxaccessiblegethelptext}

\func{virtual wxAccStatus}{GetHelpText}{\param{int }{childId}, \param{wxString* }{helpText}}

Returns help text for this object or a child, similar to tooltip text.

\membersection{wxAccessible::GetKeyboardShortcut}\label{wxaccessiblegetkeyboardshortcut}

\func{virtual wxAccStatus}{GetKeyboardShortcut}{\param{int }{childId}, \param{wxString* }{shortcut}}

Returns the keyboard shortcut for this object or child.
Return e.g. ALT+K.

\membersection{wxAccessible::GetLocation}\label{wxaccessiblegetlocation}

\func{virtual wxAccStatus}{GetLocation}{\param{wxRect\& }{rect}, \param{int }{elementId}}

Returns the rectangle for this object (id is 0) or a child element (id is greater than 0).
{\it rect} is in screen coordinates.

\membersection{wxAccessible::GetName}\label{wxaccessiblegetname}

\func{virtual wxAccStatus}{GetName}{\param{int }{childId}, \param{wxString* }{name}}

Gets the name of the specified object.

\membersection{wxAccessible::GetParent}\label{wxaccessiblegetparent}

\func{virtual wxAccStatus}{GetParent}{\param{wxAccessible** }{parent}}

Returns the parent of this object, or NULL.

\membersection{wxAccessible::GetRole}\label{wxaccessiblegetrole}

\func{virtual wxAccStatus}{GetRole}{\param{int }{childId}, \param{wxAccRole* }{role}}

Returns a role constant describing this object. See \helpref{wxAccessible}{wxaccessible} for a list
of these roles.

\membersection{wxAccessible::GetSelections}\label{wxaccessiblegetselections}

\func{virtual wxAccStatus}{GetSelections}{\param{wxVariant* }{selections}}

Gets a variant representing the selected children
of this object.

Acceptable values are:

\begin{itemize}
\item  a null variant (IsNull() returns TRUE)
\item  a list variant (GetType() == wxT("list"))
\item  an integer representing the selected child element,
or 0 if this object is selected (GetType() == wxT("long"))
\item a "void*" pointer to a wxAccessible child object
\end{itemize}

\membersection{wxAccessible::GetState}\label{wxaccessiblegetstate}

\func{virtual wxAccStatus}{GetState}{\param{int }{childId}, \param{long* }{state}}

Returns a state constant. See \helpref{wxAccessible}{wxaccessible} for a list
of these states.

\membersection{wxAccessible::GetValue}\label{wxaccessiblegetvalue}

\func{virtual wxAccStatus}{GetValue}{\param{int }{childId}, \param{wxString* }{strValue}}

Returns a localized string representing the value for the object
or child.

\membersection{wxAccessible::GetWindow}\label{wxaccessiblegetwindow}

\func{wxWindow*}{GetWindow}{\void}

Returns the window associated with this object.

\membersection{wxAccessible::HitTest}\label{wxaccessiblehittest}

\func{virtual wxAccStatus}{HitTest}{\param{const wxPoint\& }{pt}, \param{int* }{childId}, \param{wxAccessible** }{childObject}}

Returns a status value and object id to indicate whether the given point was on this or
a child object. Can return either a child object, or an integer
representing the child element, starting from 1.

{\it pt} is in screen coordinates.

\membersection{wxAccessible::Navigate}\label{wxaccessiblenavigate}

\func{virtual wxAccStatus}{Navigate}{\param{wxNavDir }{navDir}, \param{int }{fromId}, \param{int* }{toId}, \param{wxAccessible** }{toObject}}

Navigates from {\it fromId} to {\it toId}/{\it toObject}.

\membersection{wxAccessible::NotifyEvent}\label{wxaccessiblenotifyevent}

\func{virtual static void}{NotifyEvent}{\param{int}{ eventType}, \param{wxWindow* }{window}, \param{wxAccObjectt }{objectType}, \param{int }{objectType}}

Allows the application to send an event when something changes in an accessible object.

\membersection{wxAccessible::Select}\label{wxaccessibleselect}

\func{virtual wxAccStatus}{Select}{\param{int }{childId}, \param{wxAccSelectionFlags }{selectFlags}}

Selects the object or child. See \helpref{wxAccessible}{wxaccessible} for a list
of the selection actions.

\membersection{wxAccessible::SetWindow}\label{wxaccessiblesetwindow}

\func{void}{SetWindow}{\param{wxWindow* }{window}}

Sets the window associated with this object.

	265
	266	\func{}{wxAccessible}{\param{wxWindow* }{win = NULL}}
	267
	268	Constructor, taking an optional window. The object can be associated with
	269	a window later.
	270
	271	\membersection{wxAccessible::\destruct{wxAccessible}}\label{wxaccessibledtor}
	272

	274
	275	Destructor.
	276
	277	\membersection{wxAccessible::DoDefaultAction}\label{wxaccessibledodefaultaction}
	278
	279	\func{virtual wxAccStatus}{DoDefaultAction}{\param{int }{childId}}
	280
	281	Performs the default action for the object. {\it childId} is 0 (the action for this object)
282	or greater than 0 (the action for a child). Return wxACC\_NOT\_SUPPORTED if there
283	is no default action for this window (e.g. an edit control).
284
285	\membersection{wxAccessible::GetChild}\label{wxaccessiblegetchild}
286
287	\func{virtual wxAccStatus}{GetChild}{\param{int }{childId}, \param{wxAccessible** }{child}}
288
289	Gets the specified child (starting from 1). If {\it child} is NULL and the return value is wxACC\_OK,
290	this means that the child is a simple element and not an accessible object.
291
292	\membersection{wxAccessible::GetChildCount}\label{wxaccessiblegetchildcount}
293

	301
	302	Gets the default action for this object (0) or a child (greater than 0).
	303	Return wxACC\_OK even if there is no action. {\it actionName} is the action, or the empty
	304	string if there is no action. The retrieved string describes the action that is performed on an object,
	305	not what the object does as a result. For example, a toolbar button that prints
	306	a document has a default action of "Press" rather than "Prints the current document."
