-/**
- * @file lllineeditor.h
- * @brief Text editor widget to let users enter/edit a single line.
- *
- * Features:
- * Text entry of a single line (text, delete, left and right arrow, insert, return).
- * Callbacks either on every keystroke or just on the return key.
- * Focus (allow multiple text entry widgets)
- * Clipboard (cut, copy, and paste)
- * Horizontal scrolling to allow strings longer than widget size allows
- * Pre-validation (limit which keys can be used)
- * Optional line history so previous entries can be recalled by CTRL UP/DOWN
- *
