<!-- ##### SECTION Title ##### -->
GtkFileFilter

<!-- ##### SECTION Short_Description ##### -->
A filter for selecting a file subset

<!-- ##### SECTION Long_Description ##### -->
<para>
A GtkFileFilter can be used to restrict the files being shown
in a #GtkFileChooser. Files can be filtered based on their name
(with gtk_file_filter_add_pattern()), on their mime type (with
gtk_file_filter_add_mime_type()), or by a custom filter function
(with gtk_file_filter_add_custom()). 
</para>

<para>
Filtering by mime types handles aliasing and subclassing of mime
types; e.g. a filter for text/plain also matches a file with mime 
type application/rtf, since application/rtf is a subclass of 
text/plain. Note that #GtkFileFilter allows wildcards for the 
subtype of a mime type, so you can e.g. filter for image/*.
</para>

<para>
Normally, filters are used by adding them to a #GtkFileChooser,
see gtk_file_chooser_add_filter(), but it is also possible
to manually use a filter on a file with gtk_file_filter_filter().

<!-- ##### STRUCT GtkFileFilter ##### -->
<para>
The <structname>GtkFileFilter</structname> struct contains
only private fields and should not be directly accessed.
</para>


<!-- ##### STRUCT GtkFileFilterInfo ##### -->
<para>
A <structname>GtkFileFilterInfo</structname> struct is used
to pass information about the tested file to 
gtk_file_filter_filter(). 
</para>

@contains: Flags indicating which of the following fields need
  are filled
@filename: the filename of the file being tested
@uri: the URI for the file being tested
@display_name: the string that will be used to display the file
  in the file chooser
@mime_type: the mime type of the file

<!-- ##### ENUM GtkFileFilterFlags ##### -->
<para>
These flags indicate what parts of a #GtkFileFilterInfo struct
are filled or need to be filled. 
</para>

@GTK_FILE_FILTER_FILENAME: the filename of the file being tested
@GTK_FILE_FILTER_URI: the URI for the file being tested
@GTK_FILE_FILTER_DISPLAY_NAME: the string that will be used to 
  display the file in the file chooser
@GTK_FILE_FILTER_MIME_TYPE: the mime type of the file

<!-- ##### USER_FUNCTION GtkFileFilterFunc ##### -->
<para>
The type of function that is used with custom filters,
see gtk_file_filter_add_custom().
</para>

@filter_info: a #GtkFileFilterInfo that is filled according
  to the @needed flags passed to gtk_file_filter_add_custom()
@data: user data passed to gtk_file_filter_add_custom()
@Returns: %TRUE if the file should be displayed
