menu.C from Chapter 24, Menus
gives an example of using
stop_message().
stop_message() is a shortcut for
using create_ok_dialog() to create
a dialog with a label, and then
show it.
The dialog has the “stop” icon.
alert_message() creates a similar dialog
with the “alert” icon.
stop_message()'s second, optional
x::w::stop_message_config
parameter customizes the ad-hoc error message dialog's appearance.
The ad-hoc dialog gets automatically destroyed
when it's closed.
alert_message()'s second optional parameter
is unimaginatively called
x::w::alert_message_config
exception_message() takes an
x::exception
parameter instead of a plain string, and formats the exception
accordingly.
