how to make a dialog box to save files??

hi i want to make a dialog box, where i can see the file system like the action save of some other program.
how can i make this??

for a platform-independent way to get the contents of directories and work with files, I highly recommend boost::filesystem.

The GUI part is, of course, up to you

We implemented simple platform independent file dialog. You can look at file dialog in LayoutEditor in trunk.
