README for wxLayout classes
---------------------------
All the source in this directory is copyrighted under the
GPL (GNU GENERAL PUBLIC LICENSE), version 2,
by Karsten Ballueder <ballueder@usa.net>.
This is still work in progress, so if you want to make any significant
changes, please get in touch with me before.
There are three building blocks for rich text editing:
wxllist :
The wxLayoutList layout engine. It is a linked list of wxLayoutObjects
which can arrange and display them on any wxDC. I am trying to keep
this class as simple as possible, to be just the core layout
engine. All "convenience" functions should be defined in classes built
on top of this.
The wxLayoutList is derived from kbList, a double-linked list with an
interface modelled after the STL list. As wxLayoutList depends on the
way kbList treats iterators (i.e. the iterator value after an insert()
or erase() operation), I don't feel like rewriting it for wxList.
wxlwindow :
Contains a class wxLayoutWindow, derived from wxScrolledWindow which
can directly be used as a rich-text display or editing window. The
function responsible for keyboard handling is virtual and can be
overloaded for different keybindings. wxLayoutWindow can sent fake
menu-events to the application to react to the user clicking on
objects.
wxlparser:
Contains several high level functions operating on
wxLayoutList. Currently implemented is inserting of text (including
linebreaks) and export of objects, text or html.
Planned for the future is an html parser for importing html.
wxLayout.cpp is a simple test program. It will export Text and HTML to
stdout and demonstrate some of the features and bugs of wxLayoutList.
There are still things to do and I'm working on them. :-)

BUGS
=====================================================================
- dmalloc shows duplicate deletion after merging two lines and
deleting the second half
- word wrap for objects with lots of non-space needs to search in positive
direction if begin of first object is reached
TODO
=====================================================================
- typedef wxCoords CoordType ??
- merge RecalulateXXX and Layout() into one
- remove UpdateCursorScreenCoords() which is no longer needed
- UNDO!!
- replacement of llist in window
- selection highlighting is a bit broken
Improve speed! (See layout problem below!)
- wxlwindow needs to shrink scrollbar range when window contents get removed
- When selecting with the mouse, scroll window if pointer is outside.
- The import of a private data object does not work yet, we need to get
the objects back from the string.
- Changing default settings in Clear() or changing/inserting/deleting
a wxLayoutObject needs to update the m_StyleInfo in all lines, only
then can we start using that one.
- update rectangle (needs support in wxllist and wxWindows)
--> needs a bit of fixing still
some code bits are commented out in wxlwindow.cpp
offset handling seems a bit dodgy, white shadow to top/left of cursor
- DragNDrop
- Update docs, do full rtf/html editing.
- Verify html export.
