|
||
* PACKAGE: [incr Tcl]
|
||
* DESCRIPTION: Object-Oriented Extensions to Tcl
|
||
*
|
||
* [incr Tcl] provides object-oriented extensions to Tcl, much as
|
||
* C++ provides object-oriented extensions to C. It provides a means
|
||
* of encapsulating related procedures together with their shared data
|
||
* in a local namespace that is hidden from the outside world. It
|
||
* promotes code re-use through inheritance. More than anything else,
|
||
* it encourages better organization of Tcl applications through the
|
||
* object-oriented paradigm, leading to code that is easier to
|
||
* understand and maintain.
|
||
*
|
||
* ADDING [incr Tcl] TO A Tcl-BASED APPLICATION:
|
||
*
|
||
* To add [incr Tcl] facilities to a Tcl application, modify the
|
||
* Tcl_AppInit() routine as follows:
|
||
*
|
||
* 1) Include this header file near the top of the file containing
|
||
* Tcl_AppInit():
|
||
*
|
||
* #include "itcl.h"
|
||
*
|
||
* 2) Within the body of Tcl_AppInit(), add the following lines:
|
||
*
|
||
* if (Itcl_Init(interp) == TCL_ERROR) {
|
||
* return TCL_ERROR;
|
||
* }
|
||
*
|
||
* 3) Link your application with libitcl.a
|
||
*
|
||
* NOTE: An example file "tclAppInit.c" containing the changes shown
|
||
* above is included in this distribution.
|
||
