\section{\class{wxXmlResourceHandler}}\label{wxxmlresourcehandler}

wxXmlResourceHandler is an abstract base class for resource handlers
capable of creating a control from an XML node.

See \helpref{XML-based resource system overview}{xrcoverview} for details.

\membersection{wxXmlResourceHandler::wxXmlResourceHandler}\label{wxxmlresourcehandlerctor}

\func{}{wxXmlResourceHandler}{\void}

Default constructor.

\membersection{wxXmlResourceHandler::\destruct{wxXmlResourceHandler}}\label{wxxmlresourcehandlerdtor}

\func{}{\destruct{wxXmlResourceHandler}}{\void}

Destructor.

\membersection{wxXmlResourceHandler::AddStyle}\label{wxxmlresourcehandleraddstyle}

\func{void}{AddStyle}{\param{const wxString\& }{name}, \param{int }{value}}

Add a style flag (e.g. wxMB\_DOCKABLE) to the list of flags
understood by this handler.

\membersection{wxXmlResourceHandler::AddWindowStyles}\label{wxxmlresourcehandleraddwindowstyles}

\func{void}{AddWindowStyles}{\void}

Add styles common to all wxWindow-derived classes.

\membersection{wxXmlResourceHandler::CanHandle}\label{wxxmlresourcehandlercanhandle}

\func{bool}{CanHandle}{\param{wxXmlNode* }{node}}

Returns true if it understands this node and can create
a resource from it, false otherwise.

\wxheading{Note}

You must {\bf not} call any wxXmlResourceHandler methods except 
\helpref{IsOfClass}{wxxmlresourcehandlerisofclass} from this method! The instance
is not yet initialized with node data at the time CanHandle is called and it is only
safe to operate on {\it node} directly or to call IsOfClass.

\membersection{wxXmlResourceHandler::CreateChildren}\label{wxxmlresourcehandlercreatechildren}

\func{void}{CreateChildren}{\param{wxObject* }{parent}, \param{bool }{this\_hnd\_only = false}}

Creates children.

\membersection{wxXmlResourceHandler::CreateChildrenPrivately}\label{wxxmlresourcehandlercreatechildrenprivately}

\func{void}{CreateChildrenPrivately}{\param{wxObject* }{parent}, \param{wxXmlNode* }{rootnode = NULL}}

Helper function.

\membersection{wxXmlResourceHandler::CreateResFromNode}\label{wxxmlresourcehandlercreateresfromnode}

\func{wxObject*}{CreateResFromNode}{\param{wxXmlNode* }{node}, \param{wxObject* }{parent}, \param{wxObject* }{instance = NULL}}

Creates a resource from a node.

\membersection{wxXmlResourceHandler::CreateResource}\label{wxxmlresourcehandlercreateresource}

\func{wxObject*}{CreateResource}{\param{wxXmlNode* }{node}, \param{wxObject* }{parent}, \param{wxObject* }{instance}}

Creates an object (menu, dialog, control, ...) from an XML node.
Should check for validity. {\it parent} is a higher-level object (usually window, dialog or panel)
that is often necessary to create the resource.
If {\bf instance} is non-NULL it should not create a new instance via 'new' but
should rather use this one, and call its Create method.

\membersection{wxXmlResourceHandler::DoCreateResource}\label{wxxmlresourcehandlerdocreateresource}

\func{wxObject*}{DoCreateResource}{\void}

Called from CreateResource after variables
were filled.

\membersection{wxXmlResourceHandler::GetAnimation}\label{wxxmlresourcehandlergetanimation}

\func{wxAnimation}{GetAnimation}{\param{const wxString\& }{param = wxT("animation")}}

Creates a \helpref{animation}{wxanimation} from the filename specified in \arg{param}.

\membersection{wxXmlResourceHandler::GetBitmap}\label{wxxmlresourcehandlergetbitmap}

\func{wxBitmap}{GetBitmap}{\param{const wxString\& }{param = wxT("bitmap")}, \param{wxSize }{size = wxDefaultSize}}

Gets a bitmap.

\membersection{wxXmlResourceHandler::GetBool}\label{wxxmlresourcehandlergetbool}

\func{bool}{GetBool}{\param{const wxString\& }{param}, \param{bool }{defaultv = false}}

Gets a bool flag (1, t, yes, on, true are true, everything else is false).

\membersection{wxXmlResourceHandler::GetColour}\label{wxxmlresourcehandlergetcolour}

\func{wxColour}{GetColour}{\param{const wxString\& }{param}, \param{const wxColour\& }{default = wxNullColour}}

Gets colour in HTML syntax (\#RRGGBB).

\membersection{wxXmlResourceHandler::GetCurFileSystem}\label{wxxmlresourcehandlergetcurfilesystem}

\func{wxFileSystem\&}{GetCurFileSystem}{\void}

Returns the current file system.

\membersection{wxXmlResourceHandler::GetDimension}\label{wxxmlresourcehandlergetdimension}

\func{wxCoord}{GetDimension}{\param{const wxString\& }{param}, \param{wxCoord }{defaultv = 0}}

Gets a dimension (may be in dialog units).

\membersection{wxXmlResourceHandler::GetFont}\label{wxxmlresourcehandlergetfont}

\func{wxFont}{GetFont}{\param{const wxString\& }{param = wxT("font")}}

Gets a font.

\membersection{wxXmlResourceHandler::GetID}\label{wxxmlresourcehandlergetid}

\func{int}{GetID}{\void}

Returns the XRCID.

\membersection{wxXmlResourceHandler::GetIcon}\label{wxxmlresourcehandlergeticon}

Gets node content from wxXML\_ENTITY\_NODE.

\membersection{wxXmlResourceHandler::GetParamNode}\label{wxxmlresourcehandlergetparamnode}

\func{wxXmlNode*}{GetParamNode}{\param{const wxString\& }{param}}

Finds the node or returns NULL.

\membersection{wxXmlResourceHandler::GetParamValue}\label{wxxmlresourcehandlergetparamvalue}

\func{wxString}{GetParamValue}{\param{const wxString\& }{param}}

Only understands flags added with AddStyle.

\membersection{wxXmlResourceHandler::GetText}\label{wxxmlresourcehandlergettext}

Gets text from param and does some conversions:

\begin{itemize}\itemsep=0pt
\item replaces $\backslash$n, $\backslash$r, $\backslash$t by respective characters (according to C syntax)
\item replaces {\tt\$} by {\tt\&} and {\tt\$\$} by {\tt\$} (needed for {\tt\_File} to {\tt\&File}
translation because of XML syntax)
\item calls wxGetTranslations (unless disabled in wxXmlResource)
\end{itemize}

\membersection{wxXmlResourceHandler::HasParam}\label{wxxmlresourcehandlerhasparam}

\func{bool}{HasParam}{\param{const wxString\& }{param}}

Check to see if a parameter exists.

\func{bool}{IsOfClass}{\param{wxXmlNode* }{node}, \param{const wxString\& }{classname}}

Convenience function. Returns true if the node has a property class equal to classname,
e.g. <object class="wxDialog">.

\membersection{wxXmlResourceHandler::SetParentResource}\label{wxxmlresourcehandlersetparentresource}

\func{void}{SetParentResource}{\param{wxXmlResource* }{res}}
