11 Dialog boxes are a convenient way to prompt the user for a small amount of
12 input, eg. to display a message, ask a question, or anything else that does not
13 require extensive effort on the user's part.
17 Gtk+ treats a dialog as a window split horizontally. The top section is a
18 #GtkVBox, and is where widgets such as a #GtkLabel or a #GtkEntry should be
19 packed. The second area is known as the
20 <structfield>action_area</structfield>. This is generally used for packing
21 buttons into the dialog which may perform functions such as cancel, ok, or
22 apply. The two areas are separated by a #GtkHSeparator.
26 #GtkDialog boxes are created with a call to gtk_dialog_new() or
27 gtk_dialog_new_with_buttons(). gtk_dialog_new_with_buttons() is recommended; it
28 allows you to set the dialog title, some convenient flags, and add simple
33 If 'dialog' is a newly created dialog, the two primary areas of the window
34 can be accessed as GTK_DIALOG(dialog)->vbox and GTK_DIALOG(dialog)->action_area,
35 as can be seen from the example, below.
39 A 'modal' dialog (that is, one which freezes the rest of the application from
40 user input), can be created by calling gtk_window_set_modal() on the dialog. Use
41 the GTK_WINDOW() macro to cast the widget returned from gtk_dialog_new() into a
42 #GtkWindow. When using gtk_dialog_new_with_buttons() you can also pass the
43 GTK_DIALOG_MODAL flag to make a dialog modal.
47 If you add buttons to #GtkDialog using gtk_dialog_new_with_buttons(),
48 gtk_dialog_add_button(), gtk_dialog_add_buttons(), or
49 gtk_dialog_add_action_widget(), clicking the button will emit a signal called
50 "response" with a response ID that you specified. GTK+ will never assign a
51 meaning to positive response IDs; these are entirely user-defined. But for
52 convenience, you can use the response IDs in the #GtkResponseType enumeration
53 (these all have values less than zero). If a dialog receives a delete event, the
54 "response" signal will be emitted with a response ID of GTK_RESPONSE_NONE.
59 If you want to block waiting for a dialog to return before returning control
60 flow to your code, you can call gtk_dialog_run(). This function enters a
61 recursive main loop and waits for the user to respond to the dialog, returning the
62 response ID corresponding to the button the user clicked.
66 For the simple dialog in the following example, in reality you'd probably use
67 #GtkMessageDialog to save yourself some effort. But you'd need to create the
68 dialog contents manually if you had more than a simple message in the dialog.

75 void quick_message(#gchar *message) {

81 dialog = gtk_dialog_new_with_buttons ("Message",
82 main_application_window,
83 GTK_DIALOG_DESTROY_WITH_PARENT,
87 label = gtk_label_new (message);
89 /* Ensure that the dialog box is destroyed when the user responds. */
91 gtk_signal_connect_object (GTK_OBJECT (dialog), "response",
92 GTK_SIGNAL_FUNC (gtk_widget_destroy),
95 /* Add the label, and show everything we've added to the dialog. */
97 gtk_container_add (GTK_CONTAINER (GTK_DIALOG(dialog)->vbox),
99 gtk_widget_show_all (dialog);

128 <structfield>window</structfield> is a #GtkWindow, but should not be
129 modified directly, (use the functions provided, such as
130 gtk_window_set_title(). See the #GtkWindow section for more).
133 <structfield>vbox</structfield> is a #GtkVBox - the main part of the dialog box.
136 <structfield>action_area</structfield> is a #GtkHBox packed below the dividing #GtkHSeparator in the dialog. It is treated exactly the same as any other #GtkHBox.
