The Leditbox class is an editbox or multi-line editbox that allows you to enter and edit data. The enter key inserts a line feed into the editbox. The tab key (on_tab_key event) moves the focus to the next or previous object. The ctrl-tab (on_tab_key event with control key pressed) inserts spaces into the editbox.

• Working

To do:

History:

• 8/24/2003 - Completed adding support for scrollbars, cut, copy, paste, and highlighting text using the keyboard or mouse.
