Overview

XProcess is the parent class for XApplication and XThread, you cannot create an instance of XProcess, you have to chose one the child classes. This classes should only be used if you need window-management.
XProcess and derived is killed automaticaly if you use windows and/or dialogs: it counts the opened dialogs and windows, if the last window/dialog is closed the thread/application is terminated. If you dont open dialogs or windows you need to terminate the application/thread yourself.
