Text Editor Data Structures
There are tons of articles about plain text editor data structures, but what about <i>rich</i> text editor data structures? Let's say i want to implement a text editor that can have bold, italic, underline, etc text but also be able to do automatic word breaking, align paragraph text to left/middle/right, insert images and/or other objects, have floating images and/or other objects around which the other (non floating) text/images/objects wrap, etc.<p>What would be the data structures for that? I can only think of trying to replicate something like the HTML DOM but i have a feeling something like Write for Windows 3.1 used a simpler data structure.
