  2. //    This is a demo program to show how to use some of the features of
  3. //    the GUI libraries of the ObjectEase package. To compile and run this
  4. //    demo create a project file including the files GUI.LIB and GUIDEMO.CPP.
  5. //    Make sure that the files are located where the project says they are.
  6. //    You may also need to change to path to the GUI.H file in the #includes
  7. //    portion of this file.
  8. //
  9. //    Also note that the following files MUST be in the same directory as
  10. //    The executable for this program to operate properly:
  11. //
  12. //        B1.BTN
  13. //        B2.BTN
  14. //        I1.ICN
  15. //        I2.ICN
