Abstract

 This demo shows how to write commands that glue together
 existing Java applications.

Why Bother?

 In time, many applications require more functionality than 
 was originally provided.  If a feature has already been 
 implemented in a different application, you can use scripting 
 to glue the existing feature to your new application.  

 Suppose FileDialogApp and ListboxApp are existing Java applications.
 FileDialogCmd and ListboxCmd provide an interface between Tcl
 and the existing applications.  JarCmd is another example of how to 
 write new Tcl commands in Java (see simplepkg for an very simple
 example of how this is done.)  The GlueExtension class is the
 device that dynamically loads all of the new Tcl commands into
 the Interpreter.

Running The Demo

 To see the demo in action start out by typing "make demos" in the
 directory you compiled in. This will create a demos subdirectory
 in the directory you compiled in. At this point you will want to
 start up a java enabled shell and source the glue.tcl file. The
 easiest way to do this is to type "make shell" and then cd to the
 demos/gluepkg directory that was created inside the directory
 you compiled in. At this point you can just type "source glue.tcl"
 at the Tcl prompt.

 When you source the glue.tcl script, a file dialog menu will pop
 up, select a valid jar file and press OK.  This window will
 disappear and another window will be displayed.  The new window
 contains a listing of all of the files in the selected jar file.
 By selecting one or more of the files and pressing OK, the
 selected files will be extracted from the jar file and displayed
 to stdout.
