Dialog boxes are a convenient way to prompt the user for a small amount of
|
|
input, e.g. to display a message, ask a question, or anything else that does
|
|
not require extensive effort on the user's part.
|

GTK+ treats a dialog as a window split vertically. The top section is a
|
|
#GtkVBox, and is where widgets such as a #GtkLabel or a #GtkEntry should
|
|
be packed. The bottom area is known as the
|
|
<structfield>action_area</structfield>. This is generally used for
|
|
packing buttons into the dialog which may perform functions such as
|
|
cancel, ok, or apply. The two areas are separated by a #GtkHSeparator.
|
|

<para>
|
|
#GtkDialog boxes are created with a call to gtk_dialog_new() or
|
|
gtk_dialog_new_with_buttons(). gtk_dialog_new_with_buttons() is recommended; it
|
|
allows you to set the dialog title, some convenient flags, and add simple
|
|
buttons.
|
|
</para>
|
|
|
|
<para>
|
|
If 'dialog' is a newly created dialog, the two primary areas of the window
|
|
can be accessed as <literal>GTK_DIALOG(dialog)->vbox</literal> and
|
|
<literal>GTK_DIALOG(dialog)->action_area</literal>,
|
|
as can be seen from the example, below.
|
|
</para>

|
A 'modal' dialog (that is, one which freezes the rest of the application from
|
|
user input), can be created by calling gtk_window_set_modal() on the dialog. Use
|
|
the GTK_WINDOW() macro to cast the widget returned from gtk_dialog_new() into a
|
|
#GtkWindow. When using gtk_dialog_new_with_buttons() you can also pass the
|
|
#GTK_DIALOG_MODAL flag to make a dialog modal.
|
|
</para>
|
|
|
|
<para>
|
|
If you add buttons to #GtkDialog using gtk_dialog_new_with_buttons(),
|
|
gtk_dialog_add_button(), gtk_dialog_add_buttons(), or
|
|
gtk_dialog_add_action_widget(), clicking the button will emit a signal called
|
|
"response" with a response ID that you specified. GTK+ will never assign a
|
|
meaning to positive response IDs; these are entirely user-defined. But for
|
|
convenience, you can use the response IDs in the #GtkResponseType enumeration
|
|
(these all have values less than zero). If a dialog receives a delete event,
|
|
the "response" signal will be emitted with a response ID of #GTK_RESPONSE_DELETE_EVENT.
|
|
</para>
|
|
|
|
|
|
<para>
|
|
If you want to block waiting for a dialog to return before returning control
|
|
flow to your code, you can call gtk_dialog_run(). This function enters a
|
|
recursive main loop and waits for the user to respond to the dialog, returning the
|
|
response ID corresponding to the button the user clicked.
|
|
</para>

For the simple dialog in the following example, in reality you'd probably use
|
|
#GtkMessageDialog to save yourself some effort. But you'd need to create the
|
|
dialog contents manually if you had more than a simple message in the dialog.
|
|
<example>
|
|
<title>Simple <structname>GtkDialog</structname> usage.</title>
|
|

GtkWidget *dialog, *label;

dialog = gtk_dialog_new_with_buttons ("Message",

"response",

G_CALLBACK (gtk_widget_destroy),

dialog);

gtk_widget_show_all (dialog);
