## Description

## Functions

### gtk_dialog_new ()

    GtkWidget *
    gtk_dialog_new (void);

### gtk_dialog_new_with_buttons ()

    GtkWidget *
    gtk_dialog_new_with_buttons (const gchar *title,
                                 GtkWindow *parent,
                                 GtkDialogFlags flags,
                                 const gchar *first_button_text,
                                 ...);

Creates a new GtkDialog with title `title` (or `NULL` for the default title; see `gtk_window_set_title()`) and transient parent `parent` (or `NULL` for none; see `gtk_window_set_transient_for()`). The `flags` argument can be used to make the dialog modal (GTK_DIALOG_MODAL) and/or to have it destroyed along with its transient parent (GTK_DIALOG_DESTROY_WITH_PARENT). After `flags` , button text/response ID pairs should be listed, with a `NULL` pointer ending the list. Button text can be either a stock ID such as GTK_STOCK_OK, or some arbitrary text. A response ID can be any positive number, or one of the values in the GtkResponseType enumeration. If the user clicks one of these dialog buttons, GtkDialog will emit the “response” signal with the corresponding response ID. If a GtkDialog receives the “delete-event” signal, it will emit ::response with a response ID of GTK_RESPONSE_DELETE_EVENT. However, destroying a dialog does not emit the ::response signal; so be careful relying on ::response when using the GTK_DIALOG_DESTROY_WITH_PARENT flag. Buttons are from left to right, so the first button in the list will be the leftmost button in the dialog.

Here's a simple example:

    1
    2
    3
    4
    5
    6
    7
    8
    GtkWidget *dialog = gtk_dialog_new_with_buttons ("My dialog",
                                                     main_app_window,
                                                     GTK_DIALOG_MODAL | GTK_DIALOG_DESTROY_WITH_PARENT,
                                                     GTK_STOCK_OK,
                                                     GTK_RESPONSE_ACCEPT,
                                                     GTK_STOCK_CANCEL,
                                                     GTK_RESPONSE_REJECT,
                                                     NULL);

#### Parameters

title | Title of the dialog, or `NULL`. | [allow-none]
parent | Transient parent of the dialog, or `NULL`. | [allow-none]
flags | from GtkDialogFlags |
first_button_text | stock ID or text to go in first button, or `NULL`. | [allow-none]
Varargs | response ID for first button, then additional buttons, ending with `NULL` |

#### Returns

a new GtkDialog

### gtk_dialog_run ()

    gint
    gtk_dialog_run (GtkDialog *dialog);

Blocks in a recursive main loop until the `dialog` either emits the “response” signal, or is destroyed. If the dialog is destroyed during the call to `gtk_dialog_run()`, `gtk_dialog_run()` returns GTK_RESPONSE_NONE. Otherwise, it returns the response ID from the ::response signal emission.

Before entering the recursive main loop, `gtk_dialog_run()` calls `gtk_widget_show()` on the dialog for you. Note that you still need to show any children of the dialog yourself.

During `gtk_dialog_run()`, the default behavior of “delete-event” is disabled; if the dialog receives ::delete_event, it will not be destroyed as windows usually are, and `gtk_dialog_run()` will return GTK_RESPONSE_DELETE_EVENT. Also, during `gtk_dialog_run()` the dialog will be modal. You can force `gtk_dialog_run()` to return at any time by calling `gtk_dialog_response()` to emit the ::response signal. Destroying the dialog during `gtk_dialog_run()` is a very bad idea, because your post-run code won't know whether the dialog was destroyed or not.

After `gtk_dialog_run()` returns, you are responsible for hiding or destroying the dialog if you wish to do so.

Typical usage of this function might be:

    1
    2
    3
    4
    5
    6
    7
    8
    9
    10
    11
    gint result = gtk_dialog_run (GTK_DIALOG (dialog));
    switch (result)
      {
        case GTK_RESPONSE_ACCEPT:
           do_application_specific_something ();
           break;
        default:
           do_nothing_since_dialog_was_cancelled ();
           break;
      }
    gtk_widget_destroy (dialog);

Note that even though the recursive main loop gives the effect of a modal dialog (it prevents the user from interacting with other windows in the same window group while the dialog is run), callbacks such as timeouts, IO channel watches, DND drops, etc, will be triggered during a `gtk_dialog_run()` call.

#### Parameters

dialog | a GtkDialog |

#### Returns

response ID

### gtk_dialog_response ()

    void
    gtk_dialog_response (GtkDialog *dialog,
                         gint response_id);

Emits the “response” signal with the given response ID. Used to indicate that the user has responded to the dialog in some way; typically either you or `gtk_dialog_run()` will be monitoring the ::response signal and take appropriate action.

#### Parameters

dialog | a GtkDialog |
response_id | response ID |

### gtk_dialog_add_button ()

    GtkWidget *
    gtk_dialog_add_button (GtkDialog *dialog,
                           const gchar *button_text,
                           gint response_id);

Adds a button with the given text (or a stock button, if `button_text` is a stock ID) and sets things up so that clicking the button will emit the “response” signal with the given `response_id` . The button is appended to the end of the dialog's action area. The button widget is returned, but usually you don't need it.

#### Parameters

dialog | a GtkDialog |
button_text | text of button, or stock ID |
response_id | response ID for the button |

#### Returns

the button widget that was added.

[transfer none]

### gtk_dialog_add_buttons ()

    void
    gtk_dialog_add_buttons (GtkDialog *dialog,
                            const gchar *first_button_text,
                            ...);

Adds more buttons, same as calling `gtk_dialog_add_button()` repeatedly. The variable argument list should be `NULL`-terminated as with `gtk_dialog_new_with_buttons()`. Each button must have both text and response ID.

#### Parameters

dialog | a GtkDialog |
first_button_text | button text or stock ID |
Varargs | response ID for first button, then more text-response_id pairs |

### gtk_dialog_add_action_widget ()

    void
    gtk_dialog_add_action_widget (GtkDialog *dialog,
                                  GtkWidget *child,
                                  gint response_id);

Adds an activatable widget to the action area of a GtkDialog, connecting a signal handler that will emit the “response” signal on the dialog when the widget is activated. The widget is appended to the end of the dialog's action area. If you want to add a non-activatable widget, simply pack it into the `action_area` field of the GtkDialog struct.

#### Parameters

dialog | a GtkDialog |
child | an activatable widget |
response_id | response ID for `child` |

### gtk_dialog_get_has_separator ()

    gboolean
    gtk_dialog_get_has_separator (GtkDialog *dialog);

`gtk_dialog_get_has_separator` has been deprecated since version 2.22 and should not be used in newly-written code.

This function will be removed in GTK+ 3

Accessor for whether the dialog has a separator.

Sets the last widget in the dialog's action area with the given `response_id` as the default widget for the dialog. Pressing "Enter" normally activates the default widget.

#### Parameters

dialog | a GtkDialog |
response_id | a response ID |

### gtk_dialog_set_has_separator ()

    void
    gtk_dialog_set_has_separator (GtkDialog *dialog,
                                  gboolean setting);

This function will be removed in GTK+ 3

Sets whether the dialog has a separator above the buttons.

#### Parameters

dialog | a GtkDialog |
setting | `TRUE` to have a separator |

### gtk_dialog_set_response_sensitive ()

    void
    gtk_dialog_set_response_sensitive (GtkDialog *dialog,
                                       gint response_id,
                                       gboolean setting);

Calls `gtk_widget_set_sensitive (widget, `setting` )` for each widget in the dialog's action area with the given `response_id` . A convenient way to sensitize/desensitize dialog buttons.

#### Parameters

dialog | a GtkDialog |
response_id | a response ID |
setting | `TRUE` for sensitive |

### gtk_dialog_get_response_for_widget ()

    gint
    gtk_dialog_get_response_for_widget (GtkDialog *dialog,
                                        GtkWidget *widget);

Gets the response id of a widget in the action area of a dialog.

#### Parameters

dialog | a GtkDialog |
widget | a widget in the action area of `dialog` |

#### Returns

the response id of `widget` , or `GTK_RESPONSE_NONE` if `widget` doesn't have a response id set.

Since: 2.8

### gtk_dialog_get_widget_for_response ()

    GtkWidget *
    gtk_dialog_get_widget_for_response (GtkDialog *dialog,
                                        gint response_id);

Gets the widget button that uses the given response ID in the action area of a dialog.

#### Parameters

dialog | a GtkDialog |
response_id | the response ID used by the `dialog` widget |

#### Returns

the `widget` button that uses the given `response_id` , or `NULL`.

### gtk_dialog_get_action_area ()

    GtkWidget *
    gtk_dialog_get_action_area (GtkDialog *dialog);

Returns the action area of `dialog` .

#### Parameters

dialog | a GtkDialog |

#### Returns

the action area.

[transfer none]

Since: 2.14

### gtk_dialog_get_content_area ()

    GtkWidget *
    gtk_dialog_get_content_area (GtkDialog *dialog);

Returns the content area of `dialog` .

#### Parameters

dialog | a GtkDialog |

the content area GtkVBox.

[transfer none]

Since: 2.14

### gtk_alternative_dialog_button_order ()

    gboolean
    gtk_alternative_dialog_button_order (GdkScreen *screen);

Returns `TRUE` if dialogs are expected to use an alternative button order on the screen `screen` . See `gtk_dialog_set_alternative_button_order()` for more details about alternative button order.

If you need to use this function, you should probably connect to the ::notify:gtk-alternative-button-order signal on the GtkSettings object associated to `screen` , in order to be notified if the button order setting changes.

#### Parameters

screen | a GdkScreen, or `NULL` to use the default screen. | [allow-none]

#### Returns

Whether the alternative button order should be used

Since: 2.6

### gtk_dialog_set_alternative_button_order ()

    void
    gtk_dialog_set_alternative_button_order
                                   (GtkDialog *dialog,
                                    gint first_response_id,
                                    ...);

Sets an alternative button order. If the “gtk-alternative-button-order” setting is set to `TRUE`, the dialog buttons are reordered according to the order of the response ids passed to this function.

By default, GTK+ dialogs use the button order advocated by the Gnome

Human Interface Guidelines with the affirmative button at the far

right, and the cancel button left of it. But the builtin GTK+ dialogs and GtkMessageDialogs do provide an alternative button order, which is more suitable on some platforms, e.g. Windows.

Use this function after adding all the buttons to your dialog, as the following example shows:

    1
    2
    3
    4
    5
    6
    7
    8

    cancel_button = gtk_dialog_add_button (GTK_DIALOG (dialog),
                                           GTK_STOCK_CANCEL,
                                           GTK_RESPONSE_CANCEL);

    ok_button = gtk_dialog_add_button (GTK_DIALOG (dialog),
                                       GTK_STOCK_OK,
                                       GTK_RESPONSE_OK);

    gtk_widget_grab_default (ok_button);

    help_button = gtk_dialog_add_button (GTK_DIALOG (dialog),
                                         GTK_STOCK_HELP,
                                         GTK_RESPONSE_HELP);

    gtk_dialog_set_alternative_button_order (GTK_DIALOG (dialog),
                                             GTK_RESPONSE_OK,
                                             GTK_RESPONSE_CANCEL,
                                             GTK_RESPONSE_HELP,
                                             -1);

#### Parameters

dialog | a GtkDialog |
first_response_id | a response id used by one `dialog` 's buttons |
Varargs | a list of more response ids of `dialog` 's buttons, terminated by -1 |

Since: 2.6

### gtk_dialog_set_alternative_button_order_from_array ()

    void
    gtk_dialog_set_alternative_button_order_from_array
                                   (GtkDialog *dialog,
                                    gint n_params,
                                    gint *new_order);

Sets an alternative button order. If the “gtk-alternative-button-order” setting is set to `TRUE`, the dialog buttons are reordered according to the order of the response ids in `new_order` .

See `gtk_dialog_set_alternative_button_order()` for more information.

This function is for use by language bindings.

#### Parameters

dialog | a GtkDialog |
n_params | the number of response ids in `new_order` |
new_order | an array of response ids of `dialog` 's buttons. | [array length=n_params]

## Property Details

### The `“has-separator”` property

      “has-separator”            gboolean

When `TRUE`, the dialog has a separator bar above its buttons.

`GtkDialog:has-separator` has been deprecated since version 2.22 and should not be used in newly-written code.

This property will be removed in GTK+ 3.

Owner: GtkDialog

Flags: Read / Write

Default value: FALSE

## Style Property Details

Owner: GtkDialog

Flags: Read

Allowed values: >= 0

Default value: 5

### The `“button-spacing”` style property

      “button-spacing”           int

Spacing between buttons.

Owner: GtkDialog

Flags: Read

Allowed values: >= 0

Default value: 6

### The `“content-area-border”` style property

Width of border around the main dialog area.

Owner: GtkDialog

Flags: Read

Allowed values: >= 0

Default value: 2

### The `“content-area-spacing”` style property

      “content-area-spacing”     int

Default value: 0

Since: 2.16

## Signal Details

### The `“close”` signal

    void
    user_function (GtkDialog *dialog,
                   gpointer   user_data)

The ::close signal is a

keybinding signal

which gets emitted when the user uses a keybinding to close the dialog.

The default binding for this signal is the Escape key.

#### Parameters

user_data | user data set when the signal handler was connected. |

Flags: Action

### The `“response”` signal

    void
    user_function (GtkDialog *dialog,
                   int        response_id,
                   gpointer   user_data)

Emitted when an action widget is clicked, the dialog receives a delete event, or the application programmer calls `gtk_dialog_response()`. On a delete event, the response ID is GTK_RESPONSE_DELETE_EVENT. Otherwise, it depends on which action widget was clicked.

#### Parameters

dialog | the object on which the signal is emitted |
response_id | the response ID |
user_data | user data set when the signal handler was connected. |

Flags: Run Last
