## Description

The functions and objects described here make working with GTK+ and GIO more convenient.

GtkMountOperation is needed when mounting volumes: It is an implementation of GMountOperation that can be used with GIO functions for mounting volumes such as `g_file_mount_enclosing_volume()`, `g_file_mount_mountable()`, `g_volume_mount()`, `g_mount_unmount_with_operation()` and others.

When necessary, GtkMountOperation shows dialogs to ask for passwords, questions or show processes blocking unmount.

gtk_show_uri_on_window() is a convenient way to launch applications for URIs.

Another object that is worth mentioning in this context is GdkAppLaunchContext, which provides visual feedback when lauching applications.

## Functions

### gtk_mount_operation_new ()

    GMountOperation *
    gtk_mount_operation_new (GtkWindow *parent);

Creates a new GtkMountOperation

#### Parameters

parent | transient parent of the window, or `NULL`. | [allow-none]

#### Returns

a new GtkMountOperation

Since: 2.14

### gtk_mount_operation_is_showing ()

    gboolean
    gtk_mount_operation_is_showing (GtkMountOperation *op);

Returns whether the GtkMountOperation is currently displaying a window.

#### Parameters

op | a GtkMountOperation |

#### Returns

`TRUE` if `op` is currently displaying a window

Since: 2.14

### gtk_mount_operation_set_parent ()

    void
    gtk_mount_operation_set_parent (GtkMountOperation *op,
                                    GtkWindow *parent);

Sets the transient parent for windows shown by the GtkMountOperation.

#### Parameters

op | a GtkMountOperation |
parent | transient parent of the window, or `NULL`. | [allow-none]

Since: 2.14

### gtk_mount_operation_get_parent ()

    GtkWindow *
    gtk_mount_operation_get_parent (GtkMountOperation *op);

Gets the transient parent used by the GtkMountOperation

#### Parameters

op | a GtkMountOperation |

#### Returns

the transient parent for windows shown by `op` .

[transfer none]

Since: 2.14

### gtk_mount_operation_set_screen ()

    void
    gtk_mount_operation_set_screen (GtkMountOperation *op,
                                    GdkScreen *screen);

Sets the screen to show windows of the GtkMountOperation on.

#### Parameters

op | a GtkMountOperation |
screen | a GdkScreen |

Since: 2.14

### gtk_mount_operation_get_screen ()

    GdkScreen *
    gtk_mount_operation_get_screen (GtkMountOperation *op);

Gets the screen on which windows of the GtkMountOperation will be shown.

#### Parameters

op | a GtkMountOperation |

#### Returns

the screen on which windows of `op` are shown.

[transfer none]

Since: 2.14

### gtk_show_uri ()

    gboolean
    gtk_show_uri (GdkScreen *screen,
                  const gchar *uri,
                  guint32 timestamp,
                  GError **error);

`gtk_show_uri` has been deprecated since version 3.22 and should not be used in newly-written code.

Use `gtk_show_uri_on_window()` instead.

A convenience function for launching the default application to show the uri. Like `gtk_show_uri_on_window()`, but takes a screen as transient parent instead of a window.

Note that this function is deprecated as it does not pass the necessary information for helpers to parent their dialog properly, when run from sandboxed applications for example.

#### Parameters

screen | screen to show the uri on or `NULL` for the default screen. | [allow-none]
uri | the uri to show |
timestamp | a timestamp to prevent focus stealing |
error | a GError that is returned in case of errors |

#### Returns

`TRUE` on success, `FALSE` on error

Since: 2.14

### gtk_show_uri_on_window ()

    gboolean
    gtk_show_uri_on_window (GtkWindow *parent,
                            const char *uri,
                            guint32 timestamp,
                            GError **error);

This is a convenience function for launching the default application to show the uri. The uri must be of a form understood by GIO (i.e. you need to install gvfs to get support for uri schemes such as http:// or ftp://, as only local files are handled by GIO itself). Typical examples are

- `file:///home/gnome/pict.jpg`

- `http://www.gnome.org`

- `mailto:me@gnome.org`

Ideally the timestamp is taken from the event triggering the `gtk_show_uri()` call. If timestamp is not known you can take `GDK_CURRENT_TIME`.

This is the recommended call to be used as it passes information necessary for sandbox helpers to parent their dialogs properly.

#### Parameters

parent | parent window. | [allow-none]
uri | the uri to show |
timestamp | a timestamp to prevent focus stealing |
error | a GError that is returned in case of errors |

#### Returns

`TRUE` on success, `FALSE` on error

Since: 3.22
