IBM Open Class

General

An IBM C++ product originally developped by Kevin Leong, IBM Open Class (IOC) was known under several names in the C++ industry, including ICL (IBM Class Library), IUICL (IBM User Interface Class Library), and OCL (Open Class Library).

IOC was an extensive set of C++ classes that were used to build GUI applications that could then be easily cross-compiled for OS/2, Microsoft Windows, and later also for AIX. IOC also formed the basis for IBM's VisualAge for C++ graphical application builder.

Examples

The most common example would be the typical hello world:

#include <iframe.hpp>
void main()
{
    IFrameWindow frame("Hello, World!");
    frame.showModally();
}

Other examples of commonly-used classes include:

#include <istring.hpp>
IString someText("hello world");

#include <icmdhdr.hpp>
virtual Boolean myHandler::command(ICommandEvent &event) {return false;}
