   1 \section{\class{wxNodeBase}}\label{wxnode}
   2
   3 A node structure used in linked lists (see \helpref{wxList}{wxlist}) and
   4 derived classes. You should never use wxNodeBase class directly because it
   5 works with untyped (void *) data and this is unsafe. Use wxNode-derived classes
   6 which are defined by WX\_DECLARE\_LIST and WX\_DEFIBE\_LIST macros instead as
   7 described in \helpref{wxList}{wxlist} documentation (see example there). wxNode
   8 is defined for compatibility as wxNodeBase containing "wxObject *" pointer, but
   9 usage of this class is deprecated.

  25 \membersection{wxNodeBase::GetData}
  26
  27 \func{void *}{Data}{\void}
  28
  29 Retrieves the client data pointer associated with the node.
  30
  31 \membersection{wxNodeBase::GetNext}
  32
  33 \func{wxNodeBase *}{Next}{\void}
  34
  35 Retrieves the next node (NULL if at end of list).
  36
  37 \membersection{wxNodeBase::Previous}
  38
  39 \func{wxNodeBase *}{GetPrevious}{\void}
  40
  41 Retrieves the previous node (NULL if at start of list).
  42
  43 \membersection{wxNodeBase::SetData}
  44
  45 \func{void}{SetData}{\param{void *}{data}}
  46
  47 Sets the data associated with the node (usually the pointer will have been
  48 set when the node was created).
  49
  50 \membersection{wxNodeBase::IndexOf}
  51
  52 \func{int}{IndexOf}{\void}
  53
  54 Returns the zero-based index of this node within the list. The return value
  55 will be NOT\_FOUND if the node has not been added to a list yet.
