\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{wxAccObject }{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.
