## Description

The selection mechanism provides the basis for different types of communication between processes. In particular, drag and drop and GtkClipboard work via selections. You will very seldom or never need to use most of the functions in this section directly; GtkClipboard provides a nicer interface to the same functionality.

Some of the datatypes defined this section are used in the GtkClipboard and drag-and-drop API's as well. The GtkTargetEntry structure and GtkTargetList objects represent lists of data types that are supported when sending or receiving data. The GtkSelectionData object is used to store a chunk of data along with the data type and other associated information.

## Details

### GtkTargetEntry

    typedef struct {
      gchar *target;
      guint  flags;
      guint  info;
    } GtkTargetEntry;

A GtkTargetEntry structure represents a single type of data than can be supplied for by a widget for a selection or for supplied or received during drag-and-drop. It contains a string representing the drag type, a flags field (used only for drag and drop - see GtkTargetFlags), and an application assigned integer ID. The integer ID will later be passed as a signal parameter for signals like "selection_get". It allows the application to identify the target type without extensive string compares.

### GtkTargetList

    typedef struct {
      GList *list;
      guint ref_count;
    } GtkTargetList;

A GtkTargetList structure is a reference counted list of GtkTargetPair. It is used to represent the same information as a table of GtkTargetEntry, but in an efficient form. This structure should be treated as opaque.

### GtkTargetPair

    typedef struct {
      GdkAtom   target;
      guint     flags;
      guint     info;
    } GtkTargetPair;

Internally used structure in the drag-and-drop and selection handling code.

### gtk_target_list_new ()

    GtkTargetList *     gtk_target_list_new                 (const GtkTargetEntry *targets,
                                                             guint ntargets);

Creates a new GtkTargetList from an array of GtkTargetEntry.

`targets` : | Pointer to an array of GtkTargetEntry
`ntargets` : | number of entries in `targets`.
Returns : | the new GtkTargetList.

### gtk_target_list_ref ()

    GtkTargetList *     gtk_target_list_ref                 (GtkTargetList *list);

Increases the reference count of a GtkTargetList by one.

`list` : | a GtkTargetList
Returns : | the passed in GtkTargetList.

### gtk_target_list_unref ()

    void                gtk_target_list_unref               (GtkTargetList *list);

Decreases the reference count of a GtkTargetList by one. If the resulting reference count is zero, frees the list.

`list` : | a GtkTargetList

### gtk_target_list_add ()

    void                gtk_target_list_add                 (GtkTargetList *list,
                                                             GdkAtom target,
                                                             guint flags,
                                                             guint info);

Appends another target to a GtkTargetList.

`list` : | a GtkTargetList
`target` : | the interned atom representing the target
`flags` : | the flags for this target
`info` : | an ID that will be passed back to the application

### gtk_target_list_add_table ()

    void                gtk_target_list_add_table           (GtkTargetList *list,
                                                             const GtkTargetEntry *targets,
                                                             guint ntargets);

Prepends a table of GtkTargetEntry to a target list.

`list` : | a GtkTargetList
`targets` : | the table of GtkTargetEntry
`ntargets` : | number of targets in the table

### gtk_target_list_add_text_targets ()

    void                gtk_target_list_add_text_targets    (GtkTargetList *list,
                                                             guint info);

Appends the text targets supported by GtkSelection to the target list. All targets are added with the same `info`.

`list` : | a GtkTargetList
`info` : | an ID that will be passed back to the application

Since 2.6

### gtk_target_list_add_image_targets ()

    void                gtk_target_list_add_image_targets   (GtkTargetList *list,
                                                             guint info,
                                                             gboolean writable);

Appends the image targets supported by GtkSelection to the target list. All targets are added with the same `info`.

`list` : | a GtkTargetList
`info` : | an ID that will be passed back to the application
`writable` : | whether to add only targets for which GTK+ knows how to convert a pixbuf into the format

Since 2.6

### gtk_target_list_add_uri_targets ()

    void                gtk_target_list_add_uri_targets     (GtkTargetList *list,
