uim

Not a standalone command. Used within C/C++ programs via `libXmu`.

The UIM command is part of the libXmu (X Miscellaneous Utilities) library. It provides mechanisms for managing user interfaces, primarily focused on creating and manipulating simple forms with fields for data input and output within an X Window System environment. While UIM itself isn't a direct command-line tool to be invoked by the user, it's a set of routines and data structures that a developer would use in their C/C++ applications.

The routines handle things like creating forms, adding fields (text, numeric, etc.), handling user input within those fields, and providing callbacks when the user interacts with the form. It relies heavily on other X libraries like Xlib and Xt. Due to the age and relative obsolescence of Xmu, direct use of UIM in modern application development is rare, having been superseded by more modern UI frameworks like Qt and GTK.

UIM relies on the Xmu library, which is considered somewhat outdated. Modern UI frameworks are generally preferred for new application development. Direct use of UIM requires proficiency in C/C++ and X Window System programming.

To use UIM, you need to link your C/C++ program against libXmu. Header files define the functions and data structures. An example interaction might include creating a form with `UIMCreateForm`, adding text fields with `UIMCreateTextField`, and setting callbacks to handle events when the user modifies the text in the fields. Detailed documentation would be within libXmu's headers.

It is important to note that there aren't direct command-line arguments.

UIM was developed as part of the X Consortium's efforts to provide a standard set of utilities for X Window System programming. The Xmu library, including UIM, was widely used in the early days of X development, particularly for quick prototyping and creating simple user interfaces. However, its limitations and the emergence of more powerful UI toolkits have led to its decline in popularity.
