Windows applications that draw their own screen elements should pick up the size settings that the user has selected in the Display settings of the Control Panel. For example, a private dialog box manager that draws custom dialog boxes should use the dialog box font that the user has selected for the rest of the system. The same principle applies for scroll bars, custom menus, and other interface controls. Provide a magnification option in the View menu to allow flexible choice of enlarged text. Compare with Microsoft Word or Lotus 123.
Magnification features scale everything in the document to a user-selected ratio.
Use of the TrueType scalable font technology ensures that characters will remain clearly defined at almost any size. Draft mode means providing an option to display all text in a single font and size. If possible, allow the user to choose the draft font and size. Use underlining or a similar form of highlighting to indicate text that should be drawn with special formatting, such as bold or italics. Wrap to window options are helpful when displaying text documents.
