Designing a Modern System from the Ground Up
• High Performance Computing Environment at the Beamline Distributed Architecture Cross Platform Compatibility GUI’s Implemented in Tcl/Tk
• Extending this System for Remote Access Viewing the Data from a Remote Platform Live Video Feed from the Experimental Floor Remote File Access and Data Archiving General Security Considerations Delivering X-window Legacy Applications with Terminal Server
Tcl / Tk for GUI Development
Source: John Ousterhoust, IEEE Computer, March 1998
• Rapid Development GUI needs only a
fraction of the code necessary in C, C++ or Java.
Easy for the novice programmer!
Quick coding & easy maintenance is essential for rapidly changing beamline environment.
Other Advantages of Tcl /Tk
Platform Independence Unix, VMS, Mac, and Win32. Scripts can be distributed without compilation and run on any computer Tcl/Tk
has been installed on. Or…scripts can be bundled with Tcl/Tk binaries and distributed as a single
executable file.
Extensible in C/C++ Tcl was designed to be extended readily in C or C++. High performance code, multiple threads, etc., best implemented as
extensions. XOS library is used for sockets.
Object Orientation The [Incr Tcl] extension to Tcl provides object-oriented features such as
classes. The [Incr Widgets] extension provides an object oriented framework for
building complex widgets from built-in Tcl widgets.
