* 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.
+ AWT is experimental, please consider filing bugs when you encounter
+ them. The default window size for AWT is 132x40, which is set in
+ jexer.session.AWTSession.
A demo application showing the existing UI controls is available via
'java -jar jexer.jar' or 'java -Djexer.AWT=true -jar jexer.jar' .
---------------
- TTerminalWindow will hang on input from the remote if the
- TApplication is exited before closing the TTerminalWindow. This
- is due to a Java limitation/interaction between blocking reads
- (necessary to get UTF8 translation correct) and file streams.
+ TApplication is exited before the TTerminalWindow's process has
+ closed on its own. This is due to a Java limitation/interaction
+ between blocking reads (which is necessary to get UTF8 translation
+ correct) and file streams.

+ emulation limitations.

Roadmap
-------
0.0.2:
+ - Making TMenu keyboard accelerators active/inactive
- AWT:
- Blinking cursor
- - Fix mouse artifacts
+ - Handle kbTab (disable focus traversal BS)
+ - Block cursor
- ECMA48Backend running on socket
- TTreeView
- TDirectoryList
- TFileOpen
- Decide on naming convention: getText, getValue, getLabel: one or all
of them?
+ - Refactor:
+ - TKeypress:
+ - getCh() --> getChar()
+ - getAlt/getCtrl/getShift --> isAltDown / isCtrlDown / isShiftDown
+ - Other boolean getters --> isSomething
0.0.3:
- Bugs
- TSubMenu keyboard mnemonic not working
- - Making TMenu keyboard accelerators active/inactive
- TDirectoryList cannot be navigated only with keyboard
- TTreeView cannot be navigated only with keyboard
- RangeViolation after dragging scrollbar up/down
