+Similarly, subclass TWindow and add some widgets:
+
+```Java
+class MyWindow extends TWindow {
+
+ public MyWindow(TApplication application) {
+ // See TWindow's API for several constructors. This one uses the
+ // application, title, width, and height. Note that the window width
+ // and height include the borders. The widgets inside the window
+ // will see (0, 0) as the top-left corner inside the borders,
+ // i.e. what the window would see as (1, 1).
+ super(application, "My Window", 30, 20);
+
+ // See TWidget's API for convenience methods to add various kinds of
+ // widgets. Note that ANY widget can be a container for other
+ // widgets: TRadioGroup for example has TRadioButtons as child
+ // widgets.
+
+ // We will add a basic label, text entry field, and button.
+ addLabel("This is a label", 5, 3);
+ addField(5, 5, 20, false, "enter text here");
+ // For the button, we will pop up a message box if the user presses
+ // it.
+ addButton("Press &Me!", 5, 8, new TAction() {
+ public void DO() {
+ MyWindow.this.messageBox("Box Title", "You pressed me, yay!");
+ }
+ } );
+ }
+}
+```
+
+Put these into a file, compile it with jexer.jar in the classpath, run
+it and you'll see an application like this:

+
+
+
+More Examples
+-------------
+
+The examples/ folder currently contains:
+
+ * A [prototype tiling window
+ manager](/examples/JexerTilingWindowManager.java) in less than 250
+ lines of code.
+
+ * A [prototype image thumbnail
+ viewer](/examples/JexerImageViewer.java) in less than 350 lines of
+ code.
+
+jexer.demos contains official demos showing all of the existing UI
+controls. The demos can be run as follows:
+
+ * 'java -jar jexer.jar' . This will use System.in/out with
+ xterm-like sequences on non-Windows non-Mac platforms. On Windows
+ and Mac it will use a Swing JFrame.
+
+ * 'java -Djexer.Swing=true -jar jexer.jar' . This will always use
+ Swing on any platform.
+
+ * 'java -cp jexer.jar jexer.demos.Demo2 PORT' (where PORT is a
+ number to run the TCP daemon on). This will use the telnet
+ protocol to establish an 8-bit clean channel and be aware of
+ screen size changes.
+
+ * 'java -cp jexer.jar jexer.demos.Demo3' . This will use
+ System.in/out with xterm-like sequences. One can see in the code
+ how to pass a different InputReader and OutputReader to
+ TApplication, permitting a different encoding than UTF-8.
+
+ * 'java -cp jexer.jar jexer.demos.Demo4' . This demonstrates hidden
+ windows and a custom TDesktop.
+
+ * 'java -cp jexer.jar jexer.demos.Demo5' . This demonstrates two
+ demo applications using different fonts in the same Swing frame.
+
+ * 'java -cp jexer.jar jexer.demos.Demo6' . This demonstrates two
+ applications performing I/O across three screens: an xterm screen
+ and Swing screen, monitored from a third Swing screen.

+Terminal Support

+The table below lists terminals tested against Jexer's ECMA48/Xterm
+backend.
+
+| Terminal | Environment | Mouse Click | Mouse Cursor | Images |
+| -------------- | ------------------ | ----------- | ------------ | ------ |
+| xterm | X11 | yes | yes | yes |
+| lcxterm(3) | CLI, Linux console | yes | yes | no |
+| rxvt-unicode | X11 | yes | yes | no |
+| alacritty(3) | X11 | yes | yes | no |

+| qodem(3) | CLI, Linux console | yes | yes(4) | no |
+| qodem-x11(3) | X11 | yes | no | no |
+
+1 - Passes mouse to its host terminal, so will support mouse if the
+host terminal does.
+
+2 - Also fails to filter out sixel data, leaving garbage on screen.
+
+3 - Latest in repository.
+
+4 - Requires TERM=xterm-1003 before starting.
+
+5 - Opening image crashes terminal.

+
+System Properties
+-----------------
+
+The following properties control features of Jexer:
+
+ jexer.Swing
+ -----------
+
+ Used only by jexer.demos.Demo1 and jexer.demos.Demo4. If true, use
+ the Swing interface for the demo application. Default: true on
+ Windows (os.name starts with "Windows") and Mac (os.name starts with
+ "Mac"), false on non-Windows and non-Mac platforms.
+
+ jexer.Swing.cursorStyle
+ -----------------------
+
+ Used by jexer.backend.SwingTerminal. Selects the cursor style to
+ draw. Valid values are: underline, block, outline. Default:
+ underline.
+
+ jexer.Swing.tripleBuffer
+ ------------------------
+
+ Used by jexer.backend.SwingTerminal. If true, use triple-buffering
+ which reduces screen tearing but may also be slower to draw on
+ slower systems. If false, use naive Swing thread drawing, which may
+ be faster on slower systems but also more likely to have screen
+ tearing. Default: true.
+
+ jexer.TTerminal.ptypipe
+ -----------------------
+
+ Used by jexer.TTerminalWindow. If true, spawn shell using the
+ 'ptypipe' utility rather than 'script'. This permits terminals to
+ resize with the window. ptypipe is a separate C language utility,
+ available at https://gitlab.com/klamonte/ptypipe. Default: false.
+
+ jexer.TTerminal.closeOnExit
+ ---------------------------
+
+ Used by jexer.TTerminalWindow. If true, close the window when the
+ spawned shell exits. Default: false.
+
+ jexer.ECMA48.rgbColor
+ ---------------------
+
+ Used by jexer.backend.ECMA48Terminal. If true, emit T.416-style RGB
+ colors for normal system colors. This is expensive in bandwidth,
+ and potentially terrible looking for non-xterms. Default: false.
+
+ jexer.ECMA48.sixel
+ ------------------
+
+ Used by jexer.backend.ECMA48Terminal. If true, emit image data
+ using sixel, otherwise show blank cells where images could be. This
+ is expensive in bandwidth, very expensive in CPU (especially for
+ large images), and will leave artifacts on the screen if the
+ terminal does not support sixel. Default: true.
