Edit Box supports only Keyboard inputs, replying to their events with the following messages:
1. EB_MSG_CHAR - when a character is to be inserted at the end of the current text.
2. EB_MSG_DEL - when a character is to be removed from the current text.
The Edit Box Object is rendered using the assigned style scheme. The following figure illustrates the color assignments.
