GtkRecentFilter as GtkBuildable

The GtkRecentFilter 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>, <pattern> or <application> has the same effect as calling gtk_recent_filter_add_mime_type(), gtk_recent_filter_add_pattern() or gtk_recent_filter_add_application().

GtkRecentFilterFunc ()

gboolean
(*GtkRecentFilterFunc) (const GtkRecentFilterInfo *filter_info,
                        gpointer user_data);

The type of function that is used with custom filters, see gtk_recent_filter_add_custom().

gtk_recent_filter_new ()

GtkRecentFilter *
gtk_recent_filter_new (void);

Creates a new GtkRecentFilter with no rules added to it. Such filter does not accept any recently used resources, so is not particularly useful until you add rules with gtk_recent_filter_add_pattern(), gtk_recent_filter_add_mime_type(), gtk_recent_filter_add_application(), gtk_recent_filter_add_age(). To create a filter that accepts any recently used resource, use:

1
2

GtkRecentFilter *filter = gtk_recent_filter_new ();
gtk_recent_filter_add_pattern (filter, "*");

Since: 2.10

gtk_recent_filter_get_name ()

const gchar *
gtk_recent_filter_get_name (GtkRecentFilter *filter);

Gets the human-readable name for the filter. See gtk_recent_filter_set_name().

Since: 2.10

gtk_recent_filter_set_name ()

void
gtk_recent_filter_set_name (GtkRecentFilter *filter,
                            const gchar *name);

Sets the human-readable name of the filter; this is the string that will be displayed in the recently used resources selector user interface if there is a selectable list of filters.

Since: 2.10

gtk_recent_filter_add_mime_type ()

void
gtk_recent_filter_add_mime_type (GtkRecentFilter *filter,
                                 const gchar *mime_type);

Adds a rule that allows resources based on their registered MIME type.

Since: 2.10

gtk_recent_filter_add_pattern ()

void
gtk_recent_filter_add_pattern (GtkRecentFilter *filter,
                               const gchar *pattern);

Adds a rule that allows resources based on a pattern matching their display name.

Since: 2.10

gtk_recent_filter_add_pixbuf_formats ()

void
gtk_recent_filter_add_pixbuf_formats (GtkRecentFilter *filter);

Adds a rule allowing image files in the formats supported by GdkPixbuf.

Since: 2.10

gtk_recent_filter_add_application ()

void
gtk_recent_filter_add_application (GtkRecentFilter *filter,
                                   const gchar *application);

Adds a rule that allows resources based on the name of the application that has registered them.

Since: 2.10

gtk_recent_filter_add_group ()

void
gtk_recent_filter_add_group (GtkRecentFilter *filter,
                             const gchar *group);

Adds a rule that allows resources based on the name of the group to which they belong

Since: 2.10

gtk_recent_filter_add_age ()

void
gtk_recent_filter_add_age (GtkRecentFilter *filter,
                           gint days);

Adds a rule that allows resources based on their age - that is, the number of days elapsed since they were last modified.

Since: 2.10

gtk_recent_filter_add_custom ()

void
gtk_recent_filter_add_custom (GtkRecentFilter *filter,
                              GtkRecentFilterFlags needed,
                              GtkRecentFilterFunc func,
                              gpointer data,
                              GDestroyNotify data_destroy);

Adds a rule to a filter that allows resources based on a custom callback function. The bitfield needed which is passed in provides information about what sorts of information that the filter function needs; this allows GTK+ to avoid retrieving expensive information when it isn’t needed by the filter.

Since: 2.10

gtk_recent_filter_get_needed ()

GtkRecentFilterFlags
gtk_recent_filter_get_needed (GtkRecentFilter *filter);

Gets the fields that need to be filled in for the GtkRecentFilterInfo passed to gtk_recent_filter_filter()

This function will not typically be used by applications; it is intended principally for use in the implementation of GtkRecentChooser.

Since: 2.10

gtk_recent_filter_filter ()

gboolean
gtk_recent_filter_filter (GtkRecentFilter *filter,
                          const GtkRecentFilterInfo *filter_info);

Tests whether a file should be displayed according to filter . The GtkRecentFilterInfo filter_info should include the fields returned from gtk_recent_filter_get_needed(), and must set the GtkRecentFilterInfo.contains field of filter_info to indicate which fields have been set.

This function will not typically be used by applications; it is intended principally for use in the implementation of GtkRecentChooser.

Since: 2.10

GtkRecentFilter

typedef struct _GtkRecentFilter GtkRecentFilter;

struct GtkRecentFilterInfo

struct GtkRecentFilterInfo {
  GtkRecentFilterFlags contains;

  const gchar *uri;
  const gchar *display_name;
  const gchar *mime_type;
  const gchar **applications;
  const gchar **groups;

  gint age;
};

A GtkRecentFilterInfo struct is used to pass information about the tested file to gtk_recent_filter_filter().

enum GtkRecentFilterFlags

These flags indicate what parts of a GtkRecentFilterInfo struct are filled or need to be filled.
