[PyQt] QFIleDialog.getSaveFileName get the selectedFilter

[Darryl Wallace]

I prefer to use the static method for the getSaveFilename in the 
QFileDialog so that the user sees the Windows/Mac native dialog.

My problem is that if the user doesn't type the file extension the in 
the save file name (say when selecting an image type to save a file as), 
then I don't have a way of checking to see what type of file they wanted 
to save as.

Is there away to get the selectedFilter using this method?

Thanks,
Darryl
