    # directory for the dialog, and no default file name is forced. This can easilly
    # be changed in your program. This is an 'save' dialog.

    # Unlike the 'open dialog' example found elsewhere, this example does NOT
    # force the current working directory to change if the user chooses a different
    # directory than the one initially set.

        # data that the user provided to you, but since we didn't actually start
        # with any data to work with, that would be difficult.
        # 
        # The code to do so would be similar to this, assuming 'data' contains
        # the data you want to save:
        #
        # fp = file(path, 'w') # Create file anew
        # fp.write(data)
        # fp.close()
        #
        # You might want to add some error checking :-)
        #

    # Note that the current working dir didn't change. This is good since
    # that's the way we set it up.

overview = """\
This class provides the file selection dialog. It incorporates OS-native features
depending on the OS in use, and can be used both for open and save operations. 
The files displayed can be filtered by setting up a wildcard filter, multiple files
can be selected (open only), and files can be forced in a read-only mode.

There are two ways to get the results back from the dialog. GetFiles() returns only
the file names themselves, in a Python list. GetPaths() returns the full path and 
filenames combined as a Python list.

One important thing to note: if you use the file extension filters, then files saved
with the filter set to something will automatically get that extension appended to them
if it is not already there. For example, suppose the dialog was displaying the 'egg'
extension and you entered a file name of 'fried'. It would be saved as 'fried.egg.'
Yum!
