Multiple Document Interface

This program supports the Microsoft Windows Multiple Document Interface standard also known by the abbreviation MDI. As a multiple document interface, this program allows you to open a number of different documents (in our case diagrams) simultaneously in different windows and to open multiple windows that view different parts of the same document. The MDI model is very powerful for working with several diagrams at once or for managing large or complex diagrams.

Whenever you create a new diagram or open an existing diagram as described in this chapter, this program will create a new window from which to view the diagram. You can have several such windows at a time. You can also create additional views of loaded diagrams and use the window arrangement commands to minimize, maximize, cascade, and tile all of the windows.
