|api| Class API
===============


.. class:: GenericTreeItem(object)

   This class holds all the information and methods for every single item in
   :class:`CustomTreeCtrl`. This is a generic implementation of :class:`TreeItem`.

   .. method:: __init__(self, parent, text="", ct_type=0, wnd=None, image=-1, selImage=-1, data=None, separator=False)

      Default class constructor.
      For internal use: do not call it in your code!
      
      :param `parent`: the tree item parent, an instance of :class:`GenericTreeItem` (may
       be ``None`` for root items);
      :param string `text`: the tree item text;
      :param integer `ct_type`: the tree item kind. May be one of the following integers:
      
       =============== =========================================
       `ct_type` Value Description
       =============== =========================================
              0        A normal item
              1        A checkbox-like item
              2        A radiobutton-type item
       =============== =========================================
      
      :param `wnd`: if not ``None``, a non-toplevel window to be displayed next to
       the item, an instance of :class:`wx.Window`;
      :param integer `image`: an index within the normal image list specifying the image to
       use for the item in unselected state;
      :param integer `selImage`: an index within the normal image list specifying the image to
       use for the item in selected state; if `image` > -1 and `selImage` is -1, the
       same image is used for both selected and unselected items;
      :param object `data`: associate the given Python object `data` with the item;
      :param bool `separator`: ``True`` if the item is a separator, ``False`` otherwise.
      
      :note: Regarding radiobutton-type items (with `ct_type` = 2), the following
       approach is used:
      
       - All peer-nodes that are radiobuttons will be mutually exclusive. In other words,
         only one of a set of radiobuttons that share a common parent can be checked at
         once. If a radiobutton node becomes checked, then all of its peer radiobuttons
         must be unchecked.
       - If a radiobutton node becomes unchecked, then all of its child nodes will become
         inactive.
      
      
      :note: Separator items should not have children, labels, data or an associated window.
       Other issues/features associated to separator items:
      
       - You can change the color of individual separators by using :meth:`CustomTreeCtrl.SetItemTextColour() <customtreectrl.CustomTreeCtrl.SetItemTextColour>`,
         or you can use :meth:`CustomTreeCtrl.SetSeparatorColour() <customtreectrl.CustomTreeCtrl.SetSeparatorColour>` to change the color of all
         separators. The default separator colour is that returned by `SystemSettings.GetColour(wx.SYS_COLOUR_GRAYTEXT)`;
       - Separators can be selected just like any other tree item;
       - Separators cannot have text;
       - Separators cannot have children;
       - Separators cannot be edited via the ``EVT_TREE_BEGIN_LABEL_EDIT`` event.

       =============== =========================================
              0        A normal item
              1        A checkbox-like item
              2        A radiobutton-type item
       =============== =========================================
      
      :note: Regarding radiobutton-type items (with `ct_type` = 2), the following
       approach is used:
      
       - All peer-nodes that are radiobuttons will be mutually exclusive. In other words,
         only one of a set of radiobuttons that share a common parent can be checked at
         once. If a radiobutton node becomes checked, then all of its peer radiobuttons
         must be unchecked.

         inactive.
