-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.

- Layout() recalculates the objects, sizes, etc.
- Draw() just draws them with the current settings, without

- Each line has its own wxLayoutStyleInfo structure which gets updated
