Differences between versions are described within this document in paragraphs
The <resource> node contains namespace declaration, too:
- <resource xmlns="http://www.wxwindows.org/wxxrc" version="2.3.0.1">
+ <resource xmlns="http://www.wxwidgets.org/wxxrc" version="2.5.3.0">
The <resource> node is only allowed to have <object> and <object_ref>
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 wxWindows class instance. It three properties: "name", "class"
-and "subclass". "class" must always be present, it tells XRC what wxWindows
-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 is also used to construct wxWindow's id and name attributes and must be unique
-among all children of the neareset container object (wxDialog, wxFrame, wxPanel,
-wxNotebook) upside from the object in XML nodes hiearchy (two distinct containers
-may contain objects with same "name", though). "subclass" is
-optional name of class whose constructor will be called instead of the constructor
-for "class". Subclass must be available in the program that loads the resource,
-must be derived from "class" and must be registered within wxWindows' 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> 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 new <object>
-classes (and therefore different <object>'s child nodes).
-
-<object_ref> node is identical to <object>, except that it does _not_ have "class"
-property and has additonal required property "ref". It's concept is similar to Unix
-symlinks: value of the "ref" property is equal to the value of "name" property of
-some existing node (called referred node) in the resources (not neccessary top-level).
-Referred node's "class" property and all subnodes are copied in place of the referee
-<object_ref> node which is then processed as regular <object> node. If the <object_ref>
-node itself has child nodes, then these nodes _override_ any nodes from the referred node.

Style[wxSomeClass]
------------------
List of style flags that can be passed to wxSomeClass' constructor. Flags are
-written in same way as in C++ code (e.g. "wxSUNKEN_BORDER", "wxHW_SCROLLBAR_NEVER")
-and are delimined with any combination of whitespaces and '|'. Possible flags

+Font
+----
+Font value. A font can be described either in terms of its elementary
+properties, or it can be derived from one of system fonts. The font node
+may contain following subnodes (the table lists subnode name on the left and
+variable type as per the definitions above on the right side):
+
+size UnsignedInteger
+style normal | italic | slant
+weight normal | bold | light
+family roman | script | decorative | swiss | modern | teletype
+underlined Boolean
+face comma-separated list of faces
+encoding charset of the font (meaningless in Unicode build), as string
+sysfont symbolic name of system standard font
+ (one of wxSYS_*_FONT constants)
+relativesize Float, font size relative to choosen system font's size;
+ can only be used when 'sysfont' is used and when 'size' is not
+ used
+
+All of them are optional, if they are missing, wxFont default is used.
+
+Examples:
+
+ <font>
+ <face>arial,helvetica</face>
+ <size>12</size>
+ </font>
+
+ <font>
+ <sysfont>wxSYS_DEFAULT_GUI_FONT</sysfont>
+ <weight>bold</weight>
+ <relativesize>1.5</relativesize>
+ </font>
+
+
+Colour
+------
+A colour value is either explicit RGB value in the standard #rrggbb format
+where rr, gg and bb are hexadecimal case-insensitive values in the 00..FF
+range, or a symbolic name. Symbolic names are wxSYS_COLOUR_* constants defined
+by wxWidgets, written as strings.
+
+Example:
+
+ <bg>wxSYS_COLOUR_SCROLLBAR</bg>
+ <fg>#FF0000</fg>

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