It's a tile editor, nothing exciting but I thought I should tell about the new release.http://koti.mbnet.fi/paulkp/stile/stile.htmThere is also C++ source code available, but windows.h is making it quite Windows-based. Hoping to replace windows file dialog some day (only part that needs windows.h).
Check out QT for the file dialog.
If you only want to navigate up and down through directories and select files it's easy, should be doable in a day or two.
