since: 1.2

#### Description [src]

    class Adw.MessageDialog : Gtk.Window
      implements Gtk.Accessible, Gtk.Buildable, Gtk.ConstraintTarget, Gtk.Native, Gtk.Root, Gtk.ShortcutManager {
      /* No available fields */
    }

A dialog presenting a message or a question.

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 `AdwMessageDialog::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 `AdwMessageDialog: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.

When a response is activated, `AdwMessageDialog` is closed automatically.

An example of using a message dialog:

    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));

## Async API

`AdwMessageDialog` can also be used via the `adw_message_dialog_choose()` method. This API follows the GIO async pattern, and the result can be obtained by calling `adw_message_dialog_choose_finish()`, for example:

    static void
    dialog_cb (AdwMessageDialog *dialog,
               GAsyncResult     *result,
               MyWindow         *self)
    {
      const char *response = adw_message_dialog_choose_finish (dialog, result);

      // ...
    }

    static void
    show_dialog (MyWindow *self)
    {
      GtkWidget *dialog;

      dialog = adw_message_dialog_new (GTK_WINDOW (self), _("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");

      adw_message_dialog_choose (ADW_MESSAGE_DIALOG (dialog), NULL, (GAsyncReadyCallback) dialog_cb, self);
    }

## 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 `adw_message_dialog_set_response_enabled()` and `adw_message_dialog_set_response_appearance()` for details.

Example of an `AdwMessageDialog` UI definition:

    <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_cb"/>
      <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>
