You can create two types of windows:
A modal window is a restricted window that the user must respond to before moving the input focus to another window. Modal windows must be dismissed before control can be returned to a modeless window. They become active as soon as they are displayed, and require that you define a means of exit or dismissal.
A modeless window is an unrestricted window that the user can exit freely. Modeless windows, which are the default window type, can be displayed at the same time as multiple other modeless windows. They are not necessarily active when displayed.
