Differences between versions are described within this document in paragraphs
subnodes, all of which must have the "name" property.
The <object> node represents a single object (GUI element) and it usually maps
-directly to a wxWidgets class instance. It three properties: "name", "class"
+directly to a wxWidgets class instance. It has the properties: "name", "class"
and "subclass". "class" must always be present, it tells XRC what wxWidgets
object should be created in this place. The other two are optional. "name" is
ID used to identify the object. It is the value passed to the XRCID() macro and
the resource, must be derived from "class" and must be registered within
wxWidgets' RTTI system.
+Finally, an optional "insert_at" property may be present. Currently only the
+values "begin" and "end" are supported, meaning to insert the object in the
+beginning of the parent node objects list or to append it at the end (which is
+the default if this property is absent).
+
Example:
<object name="MyList1" class="wxListCtrl" subclass="MyListCtrlClass">
...
- </object>
-
+ </object>
+
<object> node may have arbitrary child nodes. What child nodes and their
semantics are class-dependent and are defined later in this document. The user
is allowed to register new object handlers within XRC and extend it to accept

+Common attributes
+-----------------
+These attributes are supported by all windows:
+
+exstyle Int
+bg Colour
+fg Colour
+enabled Boolean true
+focused Boolean false
+hidden Boolean false
+tooltip I18nString
+font Font
+help I18nString
+
wxBitmap

+This is a special case, because it does not create a wxWindow instance but
creates wxBitmap instead. Another exceptional thing is that it does not have
any attributes. Instead, the node itself is interpreted as if it were attribute
of type Bitmap.
--------
pos Position -1,-1
size Size -1,-1
-style Style[wxButton]
+style Style[wxButton]
label I18nString
default Boolean false
Supports same attributes and children nodes as wxFrame.
+wxRadioBox
+----------
+
+This control may have "dimension" (major dimension) and (initial) "selection"
+Integer subelements and a composite "content" element similar to wxCheckList.
+The only difference is that the "item" subelements can have an optional
+"tooltip=I18nString" and "helptext=I18nString" attributes to specify
+the per-item tooltip and helptext.
+
+
wxScrolledWindow
----------------
pos Position -1,-1
tool
----
- bitmap Bitmap
+ bitmap Bitmap
bitmap2 Bitmap wxNullBitmap
toggle Boolean 0
radio Boolean 0
At most one of "toggle" and "radio" attributes may be 1.
Attribute "pos" may not appear if "label" or "radio" attributes
are used or if parent wxToolBar's style contains wxTB_TEXT.

Note:
Use of "pos" attribute is strongly discouraged, it is deprecated
usage of wxToolBar and it is not supported by MSW and GTK
