Class Details¶

class Adw.AlertDialog(**kwargs)¶

Bases:: Adw.Dialog
Abstract:: No
Structure:: Adw.AlertDialogClass

A dialog presenting a message or a question.

Alert 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`AlertDialog`:py:func:::response<Adw.AlertDialog.signals.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`AlertDialog`:py:data::close-response<Adw.AlertDialog.props.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, AdwAlertDialog is closed automatically.

An example of using an alert dialog:

```c Adw.Dialog *dialog;

dialog = Adw.AlertDialog.new (_(“Replace File?”), None);

adw_alert_dialog_format_body (ADW_ALERT_DIALOG (dialog), _(“A file named “%s” already exists. Do you want to replace it?”), filename);

adw_alert_dialog_add_responses (ADW_ALERT_DIALOG (dialog), “cancel”, _(”_Cancel”), “replace”, _(”_Replace”), None);

Adw.AlertDialog.set_response_appearance (ADW_ALERT_DIALOG (dialog), “replace”, Adw.ResponseAppearance.DESTRUCTIVE);

Adw.AlertDialog.set_default_response (ADW_ALERT_DIALOG (dialog), “cancel”); Adw.AlertDialog.set_close_response (ADW_ALERT_DIALOG (dialog), “cancel”);

g_signal_connect (dialog, “response”, G_CALLBACK (response_cb), self);

Adw.Dialog.present (dialog, parent); ```

Async API

AdwAlertDialog can also be used via the [method`AlertDialog`.choose] method. This API follows the GIO async pattern, and the result can be obtained by calling [method`AlertDialog`.choose_finish], for example:

```c static void dialog_cb (Adw.AlertDialog *dialog, Gio.AsyncResult *result, MyWindow *self) { const str *response = Adw.AlertDialog.choose_finish (dialog, result);

// … }

static void show_dialog (MyWindow *self) { Adw.Dialog *dialog;

dialog = Adw.AlertDialog.new (_(“Replace File?”), None);

adw_alert_dialog_format_body (ADW_ALERT_DIALOG (dialog), _(“A file named “%s” already exists. Do you want to replace it?”), filename);

adw_alert_dialog_add_responses (ADW_ALERT_DIALOG (dialog), “cancel”, _(”_Cancel”), “replace”, _(”_Replace”), None);

Adw.AlertDialog.set_response_appearance (ADW_ALERT_DIALOG (dialog), “replace”, Adw.ResponseAppearance.DESTRUCTIVE);

Adw.AlertDialog.set_default_response (ADW_ALERT_DIALOG (dialog), “cancel”); Adw.AlertDialog.set_close_response (ADW_ALERT_DIALOG (dialog), “cancel”);

Adw.AlertDialog.choose (ADW_ALERT_DIALOG (dialog), GTK_WIDGET (self), None, (Gio.AsyncReadyCallback) dialog_cb, self); } ```

Adw.AlertDialog as Gtk.Buildable

AdwAlertDialog 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`AlertDialog`.set_response_enabled] and [method`AlertDialog`.set_response_appearance] for details.

Example of an AdwAlertDialog UI definition:

``xml <object class=”AdwAlertDialog” 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> ``

classmethod new(heading, body)¶

Parameters:

heading (str or None) – the heading
body (str or None) – the body text

Returns:

the newly created AdwAlertDialog

Return type:

Adw.Dialog

Creates a new AdwAlertDialog.

heading and body can be set to NULL. This can be useful if they need to be formatted or use markup. In that case, set them to NULL and call [method`AlertDialog`.format_body] or similar methods afterwards:

```c Adw.Dialog *dialog;

dialog = Adw.AlertDialog.new (_(“Replace File?”), None); adw_alert_dialog_format_body (ADW_ALERT_DIALOG (dialog), _(“A file named “%s” already exists. Do you want to replace it?”), filename); ```

New in version 1.5.

add_response(id, label)¶

Parameters:

id (str) – the response ID
label (str) – the response label

Adds a response with id and label to self.

Responses are represented as buttons in the dialog.

Response ID must be unique. It will be used in [signal`AlertDialog`:py:func:::response<Adw.AlertDialog.signals.response>] to tell which response had been activated, as well as to inspect and modify the response later.

An embedded underline in label indicates a mnemonic.

[method`AlertDialog`.set_response_label] can be used to change the response label after it had been added.

[method`AlertDialog`.set_response_enabled] and [method`AlertDialog`.set_response_appearance] can be used to customize the responses further.

New in version 1.5.

choose(parent, cancellable, callback, *user_data)¶

Parameters:

parent (Gtk.Widget or None) – the parent widget
cancellable (Gio.Cancellable or None) – a GCancellable to cancel the operation
callback (Gio.AsyncReadyCallback or None) – a callback to call when the operation is complete
user_data (object or None) – data to pass to callback

This function shows self to the user.

The callback will be called when the alert is dismissed. It should call [method`AlertDialog`.choose_finish] to obtain the result.

If the window is an [class`Window`] or [class`ApplicationWindow`], the dialog will be shown within it. Otherwise, it will be a separate window.

New in version 1.5.

choose_finish(result)¶
