| Abstract | While many implementations of Common Lisp provide graphical toolkits, Common Lisp as a whole lacks a standard way of creating graphical user interfaces. This is related to the fact that there is also no portable Common Lisp foreign function interface. To work around this limitation, the Lisp bindings to the Tk graphics toolkit use Lisp streams to talk to a Tcl/Tk subprocess. As a consequence, LTk is a highly portable solution to the GUI problem, allowing LTk based programs to run under 9 different Lisp implementations and the multitude of operation systems supported by Tk. LTk wraps all Tk widgets in CLOS objects, so creating and interacting with widgets is fully integrated into Lisp. Even creating new widgets by inheriting from an existing widget is supported. The LTk-remote package extends LTk by the ability to use sockets for the communication with the Tcl/TK process and thus is network transparent. To run a LTK-remote program, only a very small Tcl script is needed on the client machine. As the widgets are fully rendered by the Tcl clients, this mechanism is also highly efficient with respect to the necessary network bandwidth. This paper describes the implementation of LTk and shows the CLOS interface to the Tk widgets. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
