Examples


    To display a progress bar in a program with a FOR loop::
     
          cgProgressBar = Obj_New("CGPROGRESSBAR", /Cancel)
          cgProgressBar -> Start
          FOR j=0,9 DO BEGIN
            IF cgProgressBar -> CheckCancel() THEN BEGIN
                ok = Dialog_Message('The user cancelled operation.')

Return


            ENDIF
            Wait, 0.5 ; Would probably be doing something ELSE here!
            cgProgressBar -> Update, (j+1)*10
          ENDFOR
          cgProgressBar -> Destroy
   
    An additional example can be found my compiling the program and typing
    this command::
