XRC resources format specification
|
|
==================================
|
|
|
|
!!!!! NOT YET FINISHED !!!!!
|
|
|
|
0. Introduction
|
|
---------------
|
|
|
|
This note describes the file format used for storing XRC resources that are
|
|
used by wxXmlResource class. It is probably only useful for those implementing
|
|
dialog editors with XRC support.
|
|
|
|
If you only want to use the resources, you can choose from a number of editors:
|
|
a) wxDesigner (http://www.roebling.de)
|
|
b) XRCed (wxPython/tools)
|
|
c) wxWorkshop (http://wxworkshop.sf.net)
|
|
b) wxrcedit (contrib/utils/wxrcedit)
|
|
|
|
The XRC format is based on XML 1.0 (please consult W3C's specification). There
|
|
is no DTD available since it is not possible to fully describe the format with
|
|
the limited expressive power of DTDs.
|
|
|
|
1. Terminology
|
|
--------------
|
|
|
|
The usual XML terminology applies. In particular, we shall use the terms
|
|
"node", "property" and "value" in the XML sense:
|
|
|
|
<node property1="value1" property2="value2">...</node>
|
|
|
|
The term "attribute" is specific to XRC and refers to a property-less subnode
|
|
of an <object> or <object_ref> node. In the example bellow, <pos>, <label> and
|
|
<style> are attributes, while neither <resource> nor either of <object>s is:
|
|
|
|
<?xml version="1.0" encoding="utf-8">
|
|
<resource xmlns="http://www.wxwindows.org/wxxrc" version="2.3.0.1">
|
|
<object class="wxPanel">
|
|
<style>wxSUNKEN_BORDER</style>
|
|
<object class="wxStaticText">
|
|
<label>A label</label>
|
|
<pos>10,10</pos>
|
|
</object>
|
|
</object>
|
|
</resource>
|
|
|
|
2. Elementary description
|
|
-------------------------
|
|
|
|
XRC resource file is a well-formed XML 1.0 document. All elements of XRC file are
|
|
from the http://www.wxwindows.org/wxxrc namespace.
|
|
|
|
The root node of XRC document must be <resource>. The <resource> node has
|
|
optional "version" property. Default version (in absence of the version
|
|
property) is "0.0.0.0". The version consists of four integers separated by
|
|
periods. Version of XRC format changes only if there was an incompatible
|
|
change introduced (i.e. either the library cannot understand old resource
|
|
files or older versions of the library wouldn't understand the new format).
|
|
The first three integers are major, minor and release number of the wxWindows
|
|
release when the change was introduced, the last one is revision number and
|
|
is 0 for the first incompatible change in given wxWindows release, 1 for
|
|
the second etc.
|
|
|
|
Differences between versions are described within this document in paragraphs
|
|
entitled "Version Note".
|
|
|
|
The <resource> node contains namespace declaration, too:
|
|
|
|
<resource xmlns="http://www.wxwindows.org/wxxrc" version="2.3.0.1">
|
|
|
|
The <resource> node is only allowed to have <object> and <object_ref>
|
|
subnodes, all of which must have the "name" property.
|
|
|
|
<object> - TODO (name, class, subclass)
|
|
|
|
<object_ref> - TODO (name, ref, subclass)
|
|
|
|
