Object hierarchy for FileFilter


public class FileFilter : InitiallyUnowned, Buildable

A GtkFileFilter can be used to restrict the files being shown in a FileChooser.

Files can be filtered based on their name (with add_pattern), on their mime type (with add_mime_type), or by a custom filter function (with add_custom).

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 FileFilter 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 FileChooser, see add_filter, but it is also possible to manually use a filter on a file with filter.

GtkFileFilter as GtkBuildable

The GtkFileFilter implementation of the GtkBuildable interface supports adding rules using the <mime-types>, <patterns> and < applications> elements and listing the rules within. Specifying a <mime-type> or <pattern> has the same effect as as calling add_mime_type or add_pattern.

An example of a UI definition fragment specifying GtkFileFilter rules:

<object class="GtkFileFilter">
<mime-type>image/ *</mime-type>
