Jexer - Java Text User Interface library
========================================
This library is currently in design, but when finished it is intended
to implement a text-based windowing system loosely reminiscient of
Borland's [Turbo Vision](http://en.wikipedia.org/wiki/Turbo_Vision)
library. For those wishing to use the actual C++ Turbo Vision
library, see [Sergio Sigala's updated
version](http://tvision.sourceforge.net/) that runs on many more
platforms.
WARNING: THIS IS ALPHA CODE!
This library is intended to implement a text-based windowing system
loosely reminiscient of Borland's [Turbo
Vision](http://en.wikipedia.org/wiki/Turbo_Vision) library. For those
wishing to use the actual C++ Turbo Vision library, see [Sergio
Sigala's updated version](http://tvision.sourceforge.net/) that runs
on many more platforms.
Two backends are available:
* A command-line ECMA-48 / ANSI X3.64 type terminal (tested on Linux +
xterm) via System.in and System.out. Input/output is handled
through terminal escape sequences generated by the library itself:
ncurses is not required or linked to. xterm mouse tracking using
UTF8 coordinates is supported. This is the default backend.
* System.in/out to a command-line ECMA-48 / ANSI X3.64 type terminal
(tested on Linux + xterm). I/O is handled through terminal escape
sequences generated by the library itself: ncurses is not required
or linked to. xterm mouse tracking using UTF8 coordinates is
supported. This is the default backend on non-Windows platforms.
* Java Swing/AWT UI. This backend can be selected by setting
jexer.AWT=true.
* Java AWT UI. This backend can be selected by setting
jexer.AWT=true. This is the default backend on Windows platforms.
AWT is VERY experimental, please consider filing bugs when you
encounter them.
A demo application showing the existing UI controls is available via
'java -jar jexer.jar' or 'java -Djexer.AWT=true -jar jexer.jar' .

The library is currently under initial development, usage patterns are
still being worked on. Generally the goal will be to build
applications somewhat as follows:

Roadmap

- AWTBackend
0.0.2:
- AWT:
- Blinking cursor
- More optimal refresh
- Jittery refresh with mouse movement
- Clean up TWidget constuctors (everyone is doing setX() / setY() / set...)
- ECMA48Backend running on socket
- TTreeView
- TDirectoryList
- TFileOpen
- Decide on naming convention: getText, getValue, getLabel: one or all
of them?
- TPasswordField (displays stars when not active)
0.0.3:
