> After lots of suggestions I have as last tried programming in python.

>
> def file_ok_sel(self, w):
>
> print "%s" % self.filew.get_filename() # displays file name on
> xterm
> # create cmd to display image - qiv + filenm
> self.filenm = "qiv %s" % self.filew.get_filename()
> # display image
> os.system (self.filenm)
>
> My problem is that the python code hangs until the image (qiv) is
> killed whereas I wish the image to stay displayed while the python app
