README for wxLayout classes

||||

||||

|
||||
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.
