1 | Jexer - Java Text User Interface library |
2 | ======================================== | |
3 | ||
3cb99336 | 4 | This library implements a text-based windowing system loosely |
a7f45950 KL |
5 | reminiscent of Borland's [Turbo |
6 | Vision](http://en.wikipedia.org/wiki/Turbo_Vision) system. It looks | |
7 | like this: | |

11 | Jexer works on both Xterm-like terminals and Swing, and supports |
12 | images in both Xterm and Swing. On Swing, images are true color: | |

a7f45950 | 16 | On Xterm, images are dithered to a common palette: |

62 | The examples/ folder currently contains: | |
63 | ||
64 | * A [prototype tiling window | |
d4c334ef | 65 | manager](/examples/JexerTilingWindowManager.java) in less than 250 |
528874e2 KL |
66 | lines of code. |
67 | ||
9ad2ce4f KL |
68 | * A much slicker [prototype tiling window |
69 | manager](/examples/JexerTilingWindowManager2.java) in less than 200 | |
70 | lines of code. | |
71 | ||
5434cb2b KL |
72 | * A [prototype image thumbnail |
73 | viewer](/examples/JexerImageViewer.java) in less than 350 lines of | |
74 | code. | |

76 | jexer.demos contains official demos showing all of the existing UI |
77 | controls. The demos can be run as follows: | |
4b257bd8 KL |
78 | |
79 | * 'java -jar jexer.jar' . This will use System.in/out with | |
a7f45950 | 80 | Xterm-like sequences on non-Windows non-Mac platforms. On Windows |
92453213 | 81 | and Mac it will use a Swing JFrame. |
4b257bd8 KL |
82 | |
83 | * 'java -Djexer.Swing=true -jar jexer.jar' . This will always use | |
84 | Swing on any platform. | |
85 | ||
86 | * 'java -cp jexer.jar jexer.demos.Demo2 PORT' (where PORT is a | |
a7f45950 KL |
87 | number to run the TCP daemon on). This will use the Xterm backend |
88 | on a telnet server that will update with screen size changes. | |
4b257bd8 | 89 | |
92453213 | 90 | * 'java -cp jexer.jar jexer.demos.Demo3' . This will use |
a7f45950 | 91 | System.in/out with Xterm-like sequences. One can see in the code |
92453213 KL |
92 | how to pass a different InputReader and OutputReader to |
93 | TApplication, permitting a different encoding than UTF-8. | |
94 | ||
95 | * 'java -cp jexer.jar jexer.demos.Demo4' . This demonstrates hidden | |
96 | windows and a custom TDesktop. | |
97 | ||
88a99379 KL |
98 | * 'java -cp jexer.jar jexer.demos.Demo5' . This demonstrates two |
99 | demo applications using different fonts in the same Swing frame. | |
100 | ||
15c86fc2 | 101 | * 'java -cp jexer.jar jexer.demos.Demo6' . This demonstrates two |
a7f45950 | 102 | applications performing I/O across three screens: an Xterm screen |
15c86fc2 | 103 | and Swing screen, monitored from a third Swing screen. |
88a99379 | 104 | |
ba71ae78 KL |
105 | * 'java -cp jexer.jar jexer.demos.Demo7' . This demonstrates the |
106 | BoxLayoutManager, achieving a similar result as the | |
107 | javax.swing.BoxLayout apidocs example. | |
