User Input

User Input

This section explains the translation of physical user events into programmatic character strings or special keyboard data (such as "backspace"). This kind of work should be done by toolkits. If you can use a toolkit to manage event processing for you, do so, and blissfully ignore this section. If you are writing a toolkit text object, or are writing a truly extraordinary application, then this section is for you.

This section on user input covers these topics:

"About User Input and Input Methods" presents an overview of user input and input methods.
"About X Keyboard Support" covers X keyboard support, including keys, keycodes, keysyms, and composed characters.
"Input Methods (IMs)" describes opening and closing input methods, and IM styles.
"Input Contexts (ICs)" explains an IM styles, IC values, pre-edit and status attributes, and creating and using ICs.
"Events Under IM Control" describes differences in processing events under IM control including XFilterEvent() and LookupString routines.
