Dialog.with_buttons

Creates a new `GtkDialog` with the given title and transient parent.

The flags argument can be used to make the dialog modal, have it destroyed along with its transient parent, or make it use a headerbar.

Button text/response ID pairs should be listed in pairs, with a null pointer ending the list. Button text can be arbitrary text. A response ID can be any positive number, or one of the values in the [enum@Gtk.ResponseType] enumeration. If the user clicks one of these buttons, `GtkDialog` will emit the [signal@Gtk.Dialog:GtkDialog:response] signal with the corresponding response ID.

If a `GtkDialog` receives a delete event, it will emit response with a response ID of gtk_response_delete_event.

However, destroying a dialog does not emit the response signal; so be careful relying on response when using the gtk_dialog_destroy_with_parent flag.

Here’s a simple example: ```c GtkWindow *main_app_window; // Window the dialog should show up on GtkWidget *dialog; GtkDialogFlags flags = GTK_DIALOG_MODAL | GTK_DIALOG_DESTROY_WITH_PARENT; dialog = gtk_dialog_new_with_buttons ("My dialog", main_app_window, flags, _("_OK"), GTK_RESPONSE_ACCEPT, _("_Cancel"), GTK_RESPONSE_REJECT, NULL); ```
