   7
   8 wxXmlResourceHandler is an abstract base class for resource handlers
   9 capable of creating a control from an XML node.
  10
  11 See \helpref{XML-based resource system overview}{xrcoverview} for details.

  23 \membersection{wxXmlResourceHandler::wxXmlResourceHandler}\label{wxxmlresourcehandlerctor}
  24
  25 \func{}{wxXmlResourceHandler}{\void}
  26
  27 Default constructor.
  28
  29 \membersection{wxXmlResourceHandler::\destruct{wxXmlResourceHandler}}\label{wxxmlresourcehandlerdtor}
  30
  31 \func{}{\destruct{wxXmlResourceHandler}}{\void}
  32
  33 Destructor.
  34
  35 \membersection{wxXmlResourceHandler::AddStyle}\label{wxxmlresourcehandleraddstyle}
  36
  37 \func{void}{AddStyle}{\param{const wxString\& }{name}, \param{int }{value}}
  38
  39 Add a style flag (e.g. wxMB\_DOCKABLE) to the list of flags
  40 understood by this handler.
  41
  42 \membersection{wxXmlResourceHandler::AddWindowStyles}\label{wxxmlresourcehandleraddwindowstyles}
  43
  44 \func{void}{AddWindowStyles}{\void}
  45
  46 Add styles common to all wxWindow-derived classes.
  47
  48 \membersection{wxXmlResourceHandler::CanHandle}\label{wxxmlresourcehandlercanhandle}
  49
  50 \func{bool}{CanHandle}{\param{wxXmlNode* }{node}}
  51
  52 Returns true if it understands this node and can create
  53 a resource from it, false otherwise.
  54
  55 \wxheading{Note}
  56
  57 You must {\bf not} call any wxXmlResourceHandler methods except
  58 \helpref{IsOfClass}{wxxmlresourcehandlerisofclass} from this method! The instance
  59 is not yet initialized with node data at the time CanHandle is called and it is only
  60 safe to operate on {\it node} directly or to call IsOfClass.
  61
  62 \membersection{wxXmlResourceHandler::CreateChildren}\label{wxxmlresourcehandlercreatechildren}
  63
  64 \func{void}{CreateChildren}{\param{wxObject* }{parent}, \param{bool }{this\_hnd\_only = false}}
  65
  66 Creates children.
  67
  68 \membersection{wxXmlResourceHandler::CreateChildrenPrivately}\label{wxxmlresourcehandlercreatechildrenprivately}
  69
  70 \func{void}{CreateChildrenPrivately}{\param{wxObject* }{parent}, \param{wxXmlNode* }{rootnode = NULL}}
  71
  72 Helper function.
  73
  74 \membersection{wxXmlResourceHandler::CreateResFromNode}\label{wxxmlresourcehandlercreateresfromnode}
  75
  76 \func{wxObject*}{CreateResFromNode}{\param{wxXmlNode* }{node}, \param{wxObject* }{parent}, \param{wxObject* }{instance = NULL}}
  77
  78 Creates a resource from a node.
  79
  80 \membersection{wxXmlResourceHandler::CreateResource}\label{wxxmlresourcehandlercreateresource}
  81
  82 \func{wxObject*}{CreateResource}{\param{wxXmlNode* }{node}, \param{wxObject* }{parent}, \param{wxObject* }{instance}}
  83
  84 Creates an object (menu, dialog, control, ...) from an XML node.
  85 Should check for validity. {\it parent} is a higher-level object (usually window, dialog or panel)
  86 that is often necessary to create the resource.
  87 If {\bf instance} is non-NULL it should not create a new instance via 'new' but
  88 should rather use this one, and call its Create method.
  89
