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_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:

                                       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

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

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,
               gint       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.
