Hierarquia de Objetos
This is a filter that is basically used to restrict the the files that are shown in a GtkFileChooserWidget. You may filter the files either by basis of their names (add_pattern() ), mime types (add_mime_type() ), or files that are supported by GdkPixbuf (add_pixbuf_formats() ).
When you choose to filter by mime types, note that selecting a particular mime type will also automatically include all subclasses of that type. For example, filtering for the mime type text/plain will also include all files of type application/rtf since it a subclass of text/plain. You may also use wild card to specify your mime type, such as image/*.
The most common way to use a file filter is to add it to a GtkFileChooserWidget with the set_filter method. Of course, the same method may also be used on a GtkFileChooserButton or a GtkFileChooserDialog.
