In my previous posts here and here I showed how to create a simple application which uses Document/View framework. Now I’m going to show more complex example – image viewer with scrolling and selection rectangle.

The simplest task here is modification of our wxDocument-related class.
wxDocTemplateto handle desired file extensions (in our case it’s TXT).
