An interesting navigation feature to add to a word processor is that of thumbnail navigation -- create a thumbnail of every page in a document and display it on the left of the currently active document.
I have prepared a small sample application that shows you how to create this type of document navigation by using a small, zoomed TX Text Control.
Every page of the current document is displayed on a separate TX Text Control that is added to a scrollable panel control.
Take a look at the source code and try it out for yourself.
