....The user can see the last PVM call made by each task as the application is running. Fourth, XPVM is a post mortem analysis tool. XPVM writes out a trace file that can be replayed, stopped, stepped, and rewound in order to study the behavior of a completed parallel run. XPVM is built on TCL TK [3], which is a library for developing XWindows applications. TCL makes it easy to change, customize, and extend the XPVM interface. Figure 1 shows a snapshot of the XPVM interface during use. The interface is divided into four parts. The top row of buttons perform the basic functions of the textual ....

....the UNIX shell but better) From the implementors point of view, Tcl s advantages are its small code size, its fast execution (fast enough to use for mouse event loops) and its simple interface to C procedure calls with string arguments. Tcl has one further advantage: it is the basis for Tk [4], an X11 toolkit similar to Xt. Tk provides a base set of graphics and text oriented widgets, a mechanism for defining new widgets, and a simplified interface between user applications and the X window system. For SGI users, Tk replaces the window management and event handling services that are ....

....an independent program written in C which makes available a well dened set of functionalities through specic TCL commands. These commands extend the generic set of commands provided by TCL, which include assignment, loops, string and array manipulations, input output, etc. TCL also comes with TK [Ousterhout, 1991], a graphic toolkit allowing fast development of user interfaces for TCL based applications. As any X11 toolkit, TK can be used at two dioeerent levels, dealing respectively with composing existing graphic interactors called widgets and dening new types of widgets. TK also includes a simple ....

....[Palm1994] single stroke handwriting recognizer (similar to the one on the PalmPilot TM) allows text and gesture input. A button manager senses the user pressing and releasing Lectrice s buttons (see below) and converts the actions into commands for visible applications. Finally, the Tcl Tk [Oust1991] runtime provides a toolkit for building applications for the prototype. Lectk, a derivative of the Virtual Paper viewer, is the flagship application built specifically for Lectrice. Other applications most notably the Netscape Navigator Web browser run on a remote server and use the X ....

....with PCs, encoding is either good or fast; with IBM RS6Ks, we get both, but at considerably higher cost. As a starting point for our secure videoconferencing prototype, we chose VIC [6] the popular and sophisticated MBONE videoconferencing tool. VIC implements user interface management in Tcl Tk [7], so it is flexible and easy to extend. VIC offers optional DES encryption of the video stream, but leaves key distribution to users. VIC also includes a weak cipher that XORs the video data stream with a constant key value. This is not secure but provides a best case performance baseline. 3. ....

Graphical User Interface Tool Command Language (Tcl) is an interpreted and extensible programming language (Ousterhout, 1991). The most popular set of extensions to Tcl is a graphics tool kit, called Tk. Tk is a library for implementing of graphical applications for X windows. We used the Tcl Tk combination to implement the graphical user interface for MetVUW Workbench. Because Tcl Tk code controls both the user ....

Wafe is in some respects similar to the Tcl Tk package (Ousterhout 1991) but, instead of providing its own look and feel, integrates a variety of different GUI components primarily based on MIT s generic X Toolkit. Several components are completely unrelated with GUI. Wafe provides a C code generator to ease the integration of new components. Tool Command Language ....

A Toolkit is a library of widgets that can be called by application programs. Examples of Toolkits are the Andrew Toolkit [47] tk [48], Garnet [49] and the Java toolkit [50] Creating an interface with a toolkit can only be done by programmers, because toolkits only have a procedural interface. Call back procedures have to be provided by the programmer, which serve as event handlers for all the actions in the interface. There ....

Animation and visualization An important part of algorithm design is to visualize the dynamics of a signal processing system using interactive, animated graphics. We have linked the interpreted language Tcl [4] and its associated X window toolkit Tk [5] with the Ptolemy system. This provides a powerful, extensible environment within which users can construct customized, animated, interactive simulations. In figure 4, we show an example of how this is used. 2.3.

The VDB is written in Tcl Tk [17][18] with extensions such as a Tcl interface to POSTGRES and the icon display widget. The browser currently has 5500 lines of Tcl Tk code. VDB currently supports bibliographic, series, and keyword queries. We need to complete the panels to specify relational queries (e.g. restrictions and ....
