Alex,

Thank you for the reply!!

I'm just a python hobbyist which means - I'm not that good, yet :-)

I hadn't considered putting the 'print' statement in the OnDropFiles 
function. How simple!

BTW - I really don't want to print the names of the files. I was only 
using that as an example. I actually want to check:
1). If they're the type of files I want to accept (PDF & Tiff).
2). If the files are Landscape or Portrait.

So now (using your suggestion), I can simply do something like this:

<code>
def OnDropFiles(self, x, y, filenames):
	if checkTheseFiles(filenames):	
		[self.obj.Append(f) for f in filenames]
</code>

Where 'checkTheseFiles' is another function to maybe check the type and 
orientation. Although, I could check the file extension easily enough 
right within 'OnDropFiles'.

Thanks again for the help!!
