## Description

GtkPlacesSidebar is a widget that displays a list of frequently-used places in the file system: the user's home directory, the user's bookmarks, and volumes and drives. This widget is used as a sidebar in GtkFileChooser and may be used by file managers and similar programs.

The places sidebar displays drives and volumes, and will automatically mount or unmount them when the user selects them.

Applications can hook to various signals in the places sidebar to customize its behavior. For example, they can add extra commands to the context menu of the sidebar.

While bookmarks are completely in control of the user, the places sidebar also allows individual applications to provide extra shortcut folders that are unique to each application. For example, a Paint program may want to add a shortcut for a Clipart folder. You can do this with `gtk_places_sidebar_add_shortcut()`.

To make use of the places sidebar, an application at least needs to connect to the "open-location" signal. This is emitted when the user selects in the sidebar a location to open. The application should also call `gtk_places_sidebar_set_location()` when it changes the currently-viewed location.

## Details

### GtkPlacesSidebar

    typedef struct _GtkPlacesSidebar GtkPlacesSidebar;

### enum GtkPlacesOpenFlags

    typedef enum {
      GTK_PLACES_OPEN_NORMAL     = 1 << 0,
      GTK_PLACES_OPEN_NEW_TAB    = 1 << 1,
      GTK_PLACES_OPEN_NEW_WINDOW = 1 << 2
    } GtkPlacesOpenFlags;

These flags serve two purposes. First, the application can call `gtk_places_sidebar_set_open_flags()` using these flags as a bitmask. This tells the sidebar that the application is able to open folders selected from the sidebar in various ways, for example, in new tabs or in new windows in addition to the normal mode.

Second, when one of these values gets passed back to the application in the "open-location" signal, it means that the application should open the selected location in the normal way, in a new tab, or in a new window. The sidebar takes care of determining the desired way to open the location, based on the modifier keys that the user is pressing at the time the selection is made.

If the application never calls `gtk_places_sidebar_set_open_flags()`, then the sidebar will only use GTK_PLACES_OPEN_NORMAL in the "open-location" signal. This is the default mode of operation.

`GTK_PLACES_OPEN_NORMAL` | This is the default mode that GtkPlacesSidebar uses if no other flags are specified. It indicates that the calling application should open the selected location in the normal way, for example, in the folder view beside the sidebar.
`GTK_PLACES_OPEN_NEW_TAB` | When passed to `gtk_places_sidebar_set_open_flags()`, this indicates that the application can open folders selected from the sidebar in new tabs. This value will be passed to the "open-location" signal when the user selects that a location be opened in a new tab instead of in the standard fashion.
`GTK_PLACES_OPEN_NEW_WINDOW` | Similar to `GTK_PLACES_OPEN_NEW_TAB`, but indicates that the application can open folders in new windows.

### gtk_places_sidebar_new ()

    GtkWidget *         gtk_places_sidebar_new              (void);

Creates a new GtkPlacesSidebar widget. The application should connect to at least the "open-location" signal to be notified when the user makes a selection in the sidebar.

### gtk_places_sidebar_set_open_flags ()

    void                gtk_places_sidebar_set_open_flags   (GtkPlacesSidebar *sidebar,
                                                             GtkPlacesOpenFlags flags);

Sets the way in which the calling application can open new locations from the places sidebar. For example, some applications only open locations "directly" into their main view, while others may support opening locations in a new notebook tab or a new window.

This function is used to tell the places `sidebar` about the ways in which the application can open new locations, so that the sidebar can display (or not) the "Open in new tab" and "Open in new window" menu items as appropriate.

When the "open-location" signal is emitted, its flags argument will be set to one of the `flags` that was passed in `gtk_places_sidebar_set_open_flags()`.

Passing 0 for `flags` will cause GTK_PLACES_OPEN_NORMAL to always be sent to callbacks for the "open-location" signal.

`sidebar` : | a places sidebar
`flags` : | Bitmask of modes in which the calling application can open locations

### gtk_places_sidebar_get_open_flags ()

    GtkPlacesOpenFlags  gtk_places_sidebar_get_open_flags   (GtkPlacesSidebar *sidebar);

### gtk_places_sidebar_set_location ()

    void                gtk_places_sidebar_set_location     (GtkPlacesSidebar *sidebar,
                                                             GFile *location);

Sets the location that is being shown in the widgets surrounding the `sidebar`, for example, in a folder view in a file manager. In turn, the `sidebar` will highlight that location if it is being shown in the list of places, or it will unhighlight everything if the `location` is not among the places in the list.

`sidebar` : | a places sidebar
`location` : | location to select, or NULL for no current path. [allow-none]

Since 3.10

### gtk_places_sidebar_get_location ()

    GFile *             gtk_places_sidebar_get_location     (GtkPlacesSidebar *sidebar);

Gets the currently-selected location in the `sidebar`. This can be NULL when nothing is selected, for example, when `gtk_places_sidebar_set_location()` has been called with a location that is not among the sidebar's list of places to show.

You can use this function to get the selection in the `sidebar`. Also, if you connect to the "popup-menu" signal, you can use this function to get the location that is being referred to during the callbacks for your menu items.

`sidebar` : | a places sidebar
Returns : | a GFile with the selected location, or NULL if nothing is visually selected. [transfer full]

Since 3.10

### gtk_places_sidebar_set_show_desktop ()

    void                gtk_places_sidebar_set_show_desktop (GtkPlacesSidebar *sidebar,
                                                             gboolean show_desktop);

Sets whether the `sidebar` should show an item for the Desktop folder; this is off by default. An application may want to turn this on if the desktop environment actually supports the notion of a desktop.

`sidebar` : | a places sidebar
`show_desktop` : | whether to show an item for the Desktop folder

Since 3.10

### gtk_places_sidebar_get_show_desktop ()

    gboolean            gtk_places_sidebar_get_show_desktop (GtkPlacesSidebar *sidebar);

Returns the value previously set with `gtk_places_sidebar_set_show_desktop()`

`sidebar` : | a places sidebar
Returns : | `TRUE` if the sidebar will display a builtin shortcut to the desktop folder.

Since 3.10

### gtk_places_sidebar_add_shortcut ()

    void                gtk_places_sidebar_add_shortcut     (GtkPlacesSidebar *sidebar,
                                                             GFile *location);

Applications may want to present some folders in the places sidebar if they could be immediately useful to users. For example, a drawing program could add a "/usr/share/clipart" location when the sidebar is being used in an "Insert Clipart" dialog box.

This function adds the specified `location` to a special place for immutable shortcuts. The shortcuts are application-specific; they are not shared across applications, and they are not persistent. If this function is called multiple times with different locations, then they are added to the sidebar's list in the same order as the function is called.

`sidebar` : | a places sidebar
`location` : | location to add as an application-specific shortcut

Since 3.10

### gtk_places_sidebar_remove_shortcut ()

    void                gtk_places_sidebar_remove_shortcut  (GtkPlacesSidebar *sidebar,
                                                             GFile *location);

Removes an application-specific shortcut that has been previously been inserted with `gtk_places_sidebar_add_shortcut()`. If the `location` is not a shortcut in the sidebar, then nothing is done.

`sidebar` : | a places sidebar
`location` : | location to remove

Since 3.10

### gtk_places_sidebar_list_shortcuts ()

    GSList *            gtk_places_sidebar_list_shortcuts   (GtkPlacesSidebar *sidebar);

`sidebar` : | a places sidebar
Returns : | A GSList of GFile of the locations that have been added as application-specific shortcuts with `gtk_places_sidebar_add_shortcut()`. To free this list, you can use
    1
    g_slist_free_full (list, (GDestroyNotify) g_object_unref);
. [element-type GFile][transfer full]

Since 3.10

### gtk_places_sidebar_get_nth_bookmark ()

    GFile *             gtk_places_sidebar_get_nth_bookmark (GtkPlacesSidebar *sidebar,
                                                             gint n);

This function queries the bookmarks added by the user to the places sidebar, and returns one of them. This function is used by GtkFileChooser to implement the "Alt-1", "Alt-2", etc. shortcuts, which activate the cooresponding bookmark.

`sidebar` : | a places sidebar
`n` : | index of the bookmark to query
Returns : | The bookmark specified by the index `n`, or NULL if no such index exist. Note that the indices start at 0, even though the file chooser starts them with the keyboard shortcut "Alt-1". [transfer full]

Since 3.10

### gtk_places_sidebar_get_show_connect_to_server ()

    gboolean            gtk_places_sidebar_get_show_connect_to_server
                                                            (GtkPlacesSidebar *sidebar);

Returns the value previously set with `gtk_places_sidebar_set_show_connect_to_server()`

`sidebar` : | a places sidebar
Returns : | `TRUE` if the sidebar will display a "Connect to Server" item.

Since 3.10

### gtk_places_sidebar_set_show_connect_to_server ()

    void                gtk_places_sidebar_set_show_connect_to_server
                                                            (GtkPlacesSidebar *sidebar,
                                                             gboolean show_connect_to_server);

Sets whether the `sidebar` should show an item for connecting to a network server; this is off by default. An application may want to turn this on if it implements a way for the user to connect to network servers directly.

`sidebar` : | a places sidebar
`show_connect_to_server` : | whether to show an item for the Connect to Server command

Since 3.10

## Signal Details

### The `"drag-action-ask"` signal

    gint                user_function                      (GtkPlacesSidebar *sidebar,
                                                            gint              actions,
                                                            gpointer          user_data)      : Run Last

The places sidebar emits this signal when it needs to ask the application to pop up a menu to ask the user for which drag action to perform.

`sidebar` : | the object which received the signal.
`actions` : | Possible drag actions that need to be asked for.
`user_data` : | user data set when the signal handler was connected.
Returns : | the final drag action that the sidebar should pass to the drag side of the drag-and-drop operation.

Since 3.10

### The `"drag-action-requested"` signal

    gint                user_function                      (GtkPlacesSidebar *sidebar,
                                                            GdkDragContext   *context,
                                                            GObject          *dest_file,
                                                            gpointer          source_file_list,
                                                            gpointer          user_data)             : Run Last

When the user starts a drag-and-drop operation and the sidebar needs to ask the application for which drag action to perform, then the sidebar will emit this signal.

The application can evaluate the `context` for customary actions, or it can check the type of the files indicated by `source_file_list` against the possible actions for the destination `dest_file`.

The drag action to use must be the return value of the signal handler.

`sidebar` : | the object which received the signal.
`context` : | GdkDragContext with information about the drag operation
`dest_file` : | GFile with the tentative location that is being hovered for a drop
`source_file_list` : | List of GFile that are being dragged. [element-type GFile][transfer none]
`user_data` : | user data set when the signal handler was connected.
Returns : | The drag action to use, for example, GDK_ACTION_COPY or GDK_ACTION_MOVE, or 0 if no action is allowed here (i.e. drops are not allowed in the specified `dest_file`).

Since 3.10

### The `"drag-perform-drop"` signal

    void                user_function                      (GtkPlacesSidebar *sidebar,
                                                            GObject          *dest_file,
                                                            gpointer          source_file_list,

The places sidebar emits this signal when the user completes a drag-and-drop operation and one of the sidebar's items is the destination. This item is in the `dest_file`, and the `source_file_list` has the list of files that are dropped into it and which should be copied/moved/etc. based on the specified `action`.

`sidebar` : | the object which received the signal.
`dest_file` : | Destination GFile.
`source_file_list` : | GList of GFile that got dropped. [element-type GFile][transfer none]
`action` : | Drop action to perform.
`user_data` : | user data set when the signal handler was connected.

### The `"open-location"` signal

    void                user_function                      (GtkPlacesSidebar  *sidebar,
                                                            GObject           *location,
                                                            GtkPlacesOpenFlags open_flags,
                                                            gpointer           user_data)       : Run First

The places sidebar emits this signal when the user selects a location in it. The calling application should display the contents of that location; for example, a file manager should show a list of files in the specified location.

`sidebar` : | the object which received the signal.
`location` : | GFile to which the caller should switch.
`open_flags` : | a single value from GtkPlacesOpenFlags specifying how the `location` should be opened.
`user_data` : | user data set when the signal handler was connected.

Since 3.10

### The `"populate-popup"` signal

    void                user_function                      (GtkPlacesSidebar *sidebar,
                                                            GObject          *menu,
                                                            GObject          *selected_item,
                                                            GObject          *selected_volume,
                                                            gpointer          user_data)            : Run First

The places sidebar emits this signal when the user invokes a contextual menu on one of its items. In the signal handler, the application may add extra items to the menu as appropriate. For example, a file manager may want to add a "Properties" command to the menu.

It is not necessary to store the `selected_item` for each menu item; during their GtkMenuItem::activate callbacks, the application can use `gtk_places_sidebar_get_location()` to get the file to which the item refers.

The `selected_item` argument may be NULL in case the selection refers to a volume. In this case, `selected_volume` will be non-NULL. In this case, the calling application will have to `g_object_ref()` the `selected_volume` and keep it around for the purposes of its menu item's "activate" callback.

The `menu` and all its menu items are destroyed after the user dismisses the menu. The menu is re-created (and thus, this signal is emitted) every time the user activates the contextual menu.

`sidebar` : | the object which received the signal.

### The `"show-connect-to-server"` signal

    void                user_function                      (GtkPlacesSidebar *sidebar,
                                                            gpointer          user_data)      : Run First

The places sidebar emits this signal when it needs the calling application to present an way to connect directly to a network server. For example, the application may bring up a dialog box asking for a URL like "sftp://ftp.example.com". It is up to the application to create the corresponding mount by using, for example, `g_file_mount_enclosing_volume()`.

`sidebar` : | the object which received the signal.
`user_data` : | user data set when the signal handler was connected.

                                                            gchar            *primary,
                                                            gchar            *secondary,
                                                            gpointer          user_data)      : Run First

The places sidebar emits this signal when it needs the calling application to present an error message. Most of these messages refer to mounting or unmounting media, for example, when a drive cannot be started for some reason.

`sidebar` : | the object which received the signal.
`primary` : | primary message with a summary of the error to show.
`secondary` : | secondary message with details of the error to show.
`user_data` : | user data set when the signal handler was connected.
