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:
|
1998-06-29 08:44:36 -04:00
|
|
|
|
|
|
|
|
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. :-)
