FileChooserDialog and FILE_CHOOSER_ACTION_SAVE

[danny van elsen <danny van elsen skynet be>]

Hello all,

How do I use the /FILE_CHOOSER_ACTION_SAVE /version of 
FileChooserDialog,  when specifying Gtk::FileFilter//s?

What I want to do is: when a file is saved, impose certain extensions to 
go with a particular type of file. Like when a graphics program asks you 
to save the file, it automatically adds the  'correct' extension for a 
.jpg or .tiff file  ...

greetings, Danny. ///
