Ulc Models
Alert
UlcAlert is typically opened as a child of UlcShell, as follows:
(UlcAlert confirm: 'Do you really want to quit?'
title: 'Please Confirm'
parent: aShell)
ifTrue: [aShell parent terminate]
UlcAlert handles itself with respect to its parent, so there is no need to add alerts to UlcApplication.
