21 | There are three building blocks for rich text editing: | |
22 | ||
23 | wxllist : | |
24 | ||
25 | The wxLayoutList layout engine. It is a linked list of wxLayoutObjects | |
26 | which can arrange and display them on any wxDC. I am trying to keep | |
27 | this class as simple as possible, to be just the core layout | |
28 | engine. All "convenience" functions should be defined in classes built | |
29 | on top of this. | |
30 | The wxLayoutList is derived from kbList, a double-linked list with an | |
31 | interface modelled after the STL list. As wxLayoutList depends on the | |
32 | way kbList treats iterators (i.e. the iterator value after an insert() | |
33 | or erase() operation), I don't feel like rewriting it for wxList. | |
34 | ||
35 | wxlwindow : | |
36 | ||
37 | Contains a class wxLayoutWindow, derived from wxScrolledWindow which | |
38 | can directly be used as a rich-text display or editing window. The | |
39 | function responsible for keyboard handling is virtual and can be | |
40 | overloaded for different keybindings. wxLayoutWindow can sent fake | |
41 | menu-events to the application to react to the user clicking on | |
42 | objects. | |
43 | ||
44 | wxlparser: | |
45 | ||
46 | Contains several high level functions operating on | |
47 | wxLayoutList. Currently implemented is inserting of text (including | |
48 | linebreaks) and export of objects, text or html. | |
49 | Planned for the future is an html parser for importing html. | |
50 | ||
51 | ||
52 | wxLayout.cpp is a simple test program. It will export Text and HTML to | |
53 | stdout and demonstrate some of the features and bugs of wxLayoutList. | |
54 | ||
55 | There are still things to do and I'm working on them. :-) | |
