+/**
+ * AdwMessageDialog:
+ *
+ * A dialog presenting a message or a question.
+ *
+ * <picture>
+ * <source srcset="message-dialog-dark.png" media="(prefers-color-scheme: dark)">
+ * <img src="message-dialog.png" alt="message-dialog">
+ * </picture>
+ *
+ * Message dialogs have a heading, a body, an optional child widget, and one or
+ * multiple responses, each presented as a button.
+ *
+ * Each response has a unique string ID, and a button label. Additionally, each
+ * response can be enabled or disabled, and can have a suggested or destructive
+ * appearance.
+ *
+ * When one of the responses is activated, or the dialog is closed, the
+ * [signal@MessageDialog::response] signal will be emitted. This signal is
+ * detailed, and the detail, as well as the `response` parameter will be set to
+ * the ID of the activated response, or to the value of the
+ * [property@MessageDialog:close-response] property if the dialog had been
+ * closed without activating any of the responses.
+ *
+ * Response buttons can be presented horizontally or vertically depending on
+ * available space.
+ *
+ * An example of using a message dialog:
+ *
+ * ```c
+ * GtkWidget *dialog;
+ *
+ * dialog = adw_message_dialog_new (parent, _("Replace File?"), NULL);
+ *
+ * adw_message_dialog_format_body (ADW_MESSAGE_DIALOG (dialog),
+ * _("A file named “%s” already exists. Do you want to replace it?"),
+ * filename);
+ *
+ * adw_message_dialog_add_responses (ADW_MESSAGE_DIALOG (dialog),
+ * "cancel", _("_Cancel"),
+ * "replace", _("_Replace"),
+ * NULL);
+ *
+ * adw_message_dialog_set_response_appearance (ADW_MESSAGE_DIALOG (dialog), "replace",
ADW_RESPONSE_DESTRUCTIVE);
+ *
+ * adw_message_dialog_set_default_response (ADW_MESSAGE_DIALOG (dialog), "cancel");
+ * adw_message_dialog_set_close_response (ADW_MESSAGE_DIALOG (dialog), "cancel");
+ *
+ * g_signal_connect (dialog, "response", G_CALLBACK (response_cb), self);
+ *
+ * gtk_window_present (GTK_WINDOW (dialog));
+ * ```
+ *
+ * ## AdwMessageDialog as GtkBuildable
+ *
+ * `AdwMessageDialog` supports adding responses in UI definitions by via the
+ * `<responses>` element that may contain multiple `<response>` elements, each
+ * respresenting a response.
+ *
+ * Each of the `<response>` elements must have the `id` attribute specifying the
+ * response ID. The contents of the element are used as the response label.
+ *
+ * Response labels can be translated with the usual `translatable`, `context`
+ * and `comments` attributes.
+ *
+ * The `<response>` elements can also have `enabled` and/or `appearance`
+ * attributes. See [method@MessageDialog.set_response_enabled] and
+ * [method@MessageDialog.set_response_appearance] for details.
+ *
+ * Example of an `AdwMessageDialog` UI definition:
+ *
+ * ```xml
+ * <object class="AdwMessageDialog" id="dialog">
+ * <property name="heading" translatable="yes">Save Changes?</property>
+ * <property name="body" translatable="yes">Open documents contain unsaved changes. Changes which are not
saved will be permanently lost.</property>
+ * <property name="default-response">save</property>
+ * <property name="close-response">cancel</property>
+ * <signal name="response" handler="response_id"/>
+ * <responses>
+ * <response id="cancel" translatable="yes">_Cancel</response>
+ * <response id="discard" translatable="yes" appearance="destructive">_Discard</response>
+ * <response id="save" translatable="yes" appearance="suggested" enabled="false">_Save</response>
+ * </responses>
+ * </object>
+ * ```
+ *
+ * ## Accessibility
+ *
+ * `AdwMessageDialog` uses the `GTK_ACCESSIBLE_ROLE_DIALOG` role.
+ *
+ * Since: 1.2
+ */
+
+/**
+ * AdwResponseAppearance:
+ * @ADW_RESPONSE_DEFAULT: the default appearance.
+ * @ADW_RESPONSE_SUGGESTED: used to denote important responses such as the
+ * affirmative action.
+ * @ADW_RESPONSE_DESTRUCTIVE: used to draw attention to the potentially damaging
+ * consequences of using the response. This appearance acts as a warning to
+ * the user.

+ * Describes the possible styles of [class@MessageDialog] response buttons.
