GtkFileFilter

typedef struct _GtkFileFilter GtkFileFilter;

The GtkFileFilter struct contains only private fields and should not be directly accessed.

GtkFileFilterInfo

typedef struct {
  GtkFileFilterFlags contains;

  const gchar *filename;
  const gchar *uri;
  const gchar *display_name;
  const gchar *mime_type;
} GtkFileFilterInfo;

A GtkFileFilterInfo struct is used to pass information about the tested file to gtk_file_filter_filter().

enum GtkFileFilterFlags

typedef enum {
  GTK_FILE_FILTER_FILENAME     = 1 << 0,
  GTK_FILE_FILTER_URI          = 1 << 1,
  GTK_FILE_FILTER_DISPLAY_NAME = 1 << 2,
  GTK_FILE_FILTER_MIME_TYPE    = 1 << 3
} GtkFileFilterFlags;

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

GtkFileFilterFunc ()

gboolean            (*GtkFileFilterFunc)                (const GtkFileFilterInfo *filter_info,
                                                         gpointer data);

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

gtk_file_filter_new ()

GtkFileFilter*      gtk_file_filter_new                 (void);

Creates a new GtkFileFilter with no rules added to it. Such a filter doesn't accept any files, so is not particularly useful until you add rules with gtk_file_filter_add_mime_type(), gtk_file_filter_add_pattern(), or gtk_file_filter_add_custom(). To create a filter that accepts any file, use:

GtkFileFilter *filter = gtk_file_filter_new ();
gtk_file_filter_add_pattern (filter, "*");

Since 2.4

gtk_file_filter_set_name ()

void                gtk_file_filter_set_name            (GtkFileFilter *filter,
                                                         const gchar *name);

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

Since 2.4

gtk_file_filter_get_name ()

const gchar*        gtk_file_filter_get_name            (GtkFileFilter *filter);

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

Since 2.4

gtk_file_filter_add_mime_type ()

void                gtk_file_filter_add_mime_type       (GtkFileFilter *filter,
                                                         const gchar *mime_type);

Adds a rule allowing a given mime type to filter.

Since 2.4

gtk_file_filter_add_pattern ()

void                gtk_file_filter_add_pattern         (GtkFileFilter *filter,
                                                         const gchar *pattern);

Adds a rule allowing a shell style glob to a filter.

Since 2.4

gtk_file_filter_add_pixbuf_formats ()

void                gtk_file_filter_add_pixbuf_formats  (GtkFileFilter *filter);

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

Since 2.6

gtk_file_filter_add_custom ()

void                gtk_file_filter_add_custom          (GtkFileFilter *filter,
                                                         GtkFileFilterFlags needed,
                                                         GtkFileFilterFunc func,
                                                         gpointer data,
                                                         GDestroyNotify notify);

Adds rule to a filter that allows files 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 2.4

gtk_file_filter_get_needed ()

GtkFileFilterFlags  gtk_file_filter_get_needed          (GtkFileFilter *filter);

Gets the fields that need to be filled in for the structure passed to gtk_file_filter_filter()

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

Since 2.4

gtk_file_filter_filter ()

gboolean            gtk_file_filter_filter              (GtkFileFilter *filter,
                                                         const GtkFileFilterInfo *filter_info);

Tests whether a file should be displayed according to filter. The GtkFileFilterInfo structure filter_info should include the fields returned from gtk_file_filter_get_needed().

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