10 | This is still work in progress, so if you want to make any significant | |
11 | changes, please get in touch with me before. | |

14 | |
15 | wxllist : | |
16 | ||
17 | The wxLayoutList layout engine. It is a linked list of wxLayoutObjects | |
18 | which can arrange and display them on any wxDC. I am trying to keep | |
19 | this class as simple as possible, to be just the core layout | |
20 | engine. All "convenience" functions should be defined in classes built | |
21 | on top of this. | |
22 | The wxLayoutList is derived from kbList, a double-linked list with an | |
23 | interface modelled after the STL list. As wxLayoutList depends on the | |
24 | way kbList treats iterators (i.e. the iterator value after an insert() | |
25 | or erase() operation), I don't feel like rewriting it for wxList. | |
26 | ||
27 | wxlwindow : | |
28 | ||
29 | Contains a class wxLayoutWindow, derived from wxScrolledWindow which | |
30 | can directly be used as a rich-text display or editing window. The | |
31 | function responsible for keyboard handling is virtual and can be | |
32 | overloaded for different keybindings. wxLayoutWindow can sent fake | |
33 | menu-events to the application to react to the user clicking on | |
34 | objects. | |
35 | ||
36 | wxlparser: | |
37 | ||
38 | Contains several high level functions operating on | |
39 | wxLayoutList. Currently implemented is inserting of text (including | |
40 | linebreaks) and export of objects, text or html. | |
41 | Planned for the future is an html parser for importing html. | |
42 | ||
43 | ||
44 | wxLayout.cpp is a simple test program. It will export Text and HTML to | |
45 | stdout and demonstrate some of the features and bugs of wxLayoutList. | |
46 | ||
47 | There are still things to do and I'm working on them. :-) | |
