1 | XRC resources format specification |
2 | ================================== | |
3 | ||
4 | !!!!! NOT YET FINISHED !!!!! | |
5 | ||
6 | 0. Introduction | |
7 | --------------- | |
8 | ||
9 | This note describes the file format used for storing XRC resources that are | |
10 | used by wxXmlResource class. It is probably only useful for those implementing | |
11 | dialog editors with XRC support. | |
12 | ||
13 | If you only want to use the resources, you can choose from a number of editors: | |
14 | a) wxDesigner (http://www.roebling.de) | |
15 | b) XRCed (wxPython/tools) | |
16 | c) wxWorkshop (http://wxworkshop.sf.net) | |
17 | b) wxrcedit (contrib/utils/wxrcedit) | |
18 | ||
19 | The XRC format is based on XML 1.0 (please consult W3C's specification). There | |
20 | is no DTD available since it is not possible to fully describe the format with | |
21 | the limited expressive power of DTDs. | |
22 | ||
23 | 1. Terminology | |
24 | -------------- | |
25 | ||
26 | The usual XML terminology applies. In particular, we shall use the terms | |
27 | "node", "property" and "value" in the XML sense: | |
28 | ||
29 | <node property1="value1" property2="value2">...</node> | |
30 | ||
31 | The term "attribute" is specific to XRC and refers to a property-less subnode | |
32 | of an <object> or <object_ref> node. In the example bellow, <pos>, <label> and | |
33 | <style> are attributes, while neither <resource> nor either of <object>s is: | |
34 | ||
35 | <?xml version="1.0" encoding="utf-8"> | |
36 | <resource version="2.3.0.1"> | |
37 | <object class="wxPanel"> | |
38 | <style>wxSUNKEN_BORDER</style> | |
39 | <object class="wxStaticText"> | |
40 | <label>A label</label> | |
41 | <pos>10,10</pos> | |
42 | </object> | |
43 | </object> | |
44 | </resource> | |
45 | ||
46 | 2. Elementary description | |
47 | ------------------------- | |
48 | ||
49 | XRC resource file is a well-formed XML 1.0 document. | |
50 | ||
51 | The root node of XRC document must be <resource>. The <resource> node has | |
52 | optional "version" property. Default version (in absence of the version | |
53 | property) is "0.0.0.0". The version consists of four integers separated by | |
54 | periods. Version of XRC format changes only if there was an incompatible | |
55 | change introduced (i.e. either the library cannot understand old resource | |
56 | files or older versions of the library wouldn't understand the new format). | |
57 | The first three integers are major, minor and release number of the wxWindows | |
58 | release when the change was introduced, the last one is revision number and | |
59 | is 0 for the first incompatible change in given wxWindows release, 1 for | |
60 | the second etc. | |
61 | ||
62 | Differences between versions are described within this document in paragraphs | |
63 | entitled "Version Note". | |
64 | ||
65 | The <resource> node is only allowed to have <object> and <object_ref> | |
66 | subnodes, all of which must have the "name" property. | |
67 | ||
68 | <object> - TODO (name, class, subclass) | |
69 | ||
70 | <object_ref> - TODO (name, ref, subclass) | |
71 | ||
