A GtkFileFilter can be used to restrict the files being shown
in a GtkFileChooser
. Files can be filtered based on their name
(with gtkFileFilterAddPattern
), on their mime type (with
gtkFileFilterAddMimeType
), or by a custom filter function
(with gtkFileFilterAddCustom
).
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/*.
Normally, filters are used by adding them to a GtkFileChooser
,
see gtkFileChooserAddFilter
, but it is also possible
to manually use a filter on a file with gtkFileFilterFilter
.
