gtk:alert-dialog-show (dialog parent)

dialog -- a gtk:alert-dialog object
parent -- a parent gtk:window widget

Show the alert dialog to the user. This function is a simple version of the gtk:alert-dialog-choose function intended for alert dialogs with a single button. If you want to cancel the alert dialog or if the alert dialog has more than one button, you should use that function instead and provide it with a g:cancellable object or callback respectively.
