Get file type from the "asksaveasfilename" function

Question

I am using tkFileDialog.asksaveasfilename function in a GUI. The following is the code:

def onSaveImage(self):
    ftypes = [('PNG', '*.png'), ('JPEG', '*.jpg'), ('PDF', '*.pdf')]
    imagefname = tkFileDialog.asksaveasfilename(parent=self, filetypes = ftypes)

The function to save the file is deduced from the filename extension. Is there a more elegant way to get the users choice of file type from the file dialog itself?

Answer 1

Maybe now it's late but Try to set defaultextension

saveDirectory=asksaveasfilename(defaultextension=".*",filetypes = (("JPEG files","*.jpg"),('all files','*.*')))

you'll get the result is the filename following by the the users choice of file type
