CustomerView v03-00 24May13
|
||
|
|
-------------
|
||
|
|
The "view" (or "gui") part of the Customer component - part of the sample
|
||
|
|
Order Management application.
|
||
|
|
Changes:
|
||
|
|
v00-02: Prevented close on enter key by providing no-op "ok" method.
|
||
|
|
Changed tab order on window by changing sequence of controls in .rc file
|
||
|
|
v00-03: Changed symbolic IDs to conform with naming convention
|
||
|
|
Added initAutoDetection method because deleted dlgData. from
|
||
|
|
dlg~new statement in starter.rex.
|
||
|
|
v00-04: Took out the OK method - include that in Exercise05.
|
||
|
|
v00-05: Modified to use CustomerData and CustomerModel classes.
|
||
|
|
Mods after Exercise04:
|
||
|
|
v02-00: Added "newInstance" class method - removed routine "StartCustomerView".
|
||
|
|
v02-01 19Sep11: Corrected for stand-alone invocation.
|
||
|
|
v02-02 04Oct11: Added msgbox for unimplemented menu item.
|
||
|
|
v02-03 28Jan12: Changed class name HRS to HRSclv to allow for multiple
|
||
|
|
HRS classes in same file at some future time.
|
||
|
|
v02-04 11Feb12: moved .application~setDefaults() to app startup file.
|
||
|
|
changed to .application~addToConstDir() here.
|
||
|
|
v02-05 19Feb12: Moved .Application~addToConstDir statement from newInstance
|
||
|
|
method to top of file - just before ::requires statement(s).
|
||
|
|
v03-00 09Aug12: Changed to use MVF. Stand-alone startup removed.
|
||
|
|
09Jan13: Removed stand-alone startup (not now needed).
|
||
|
|
Commented out most 'say' instructions.
|
||
|
|
Removed 'getData' method - redundant with MVF.
|
||
|
|
Modified handling of Cust Address due to change in data
|
||
|
|
format of Cust Address (now provided as string via MVF
|
||
|
|
from Customer File).
|
||
|
|
Deleted a number of "say" instructions.
