VMSSheetManager

In order to make an application window or sheet visible within the application frame, we have to add code to the VMSSheetManager. Figure 12-5 shows the additional code required for this class to handle the Employee List window.

You can see from the additional code listed for the {open-sheet} method in Figure 12-5 that enabling the VMSSheetManager to handle another window is as simple as creating a new case clause in the {switch} expression. We have added code that executes when the "employee" String is passed across as the method argument, which uses the {create-layout} method on the EmployeeSheet class to first create the visual elements on the window and then call the {add-sheet} method to present a new sheet to the user.
