Tuohy Augmentations: Validate_items Next Val_MX.pkg - Validate Mixin for alternate validation capabilities. 1. Validate_All_Items_State property - Is set TRUE during a save validation and false during a navigation validation. Let's developer take different actions based on a save validate and a navigate validate. 2. Validate_Mode - Determines when validations are sent. VALIDATE_DEFAULT Works the way it does now. Validates occur if Object_Validation is TRUE (which is the default). This means that validates normally occur during downward navigation and save (when Validate_Items is sent by DSO). VALIDATE_ON_SAVE Validates are only sent during a save. When this property is set object_validation is also set FALSE. It is only turned on inside of Validate_Items. VALIDATE_ON_SAVE_NEXT Validates are only sent during a save and during NEXT navigation (ENTER and TAB). When this property is set object_validation is also set FALSE. It is only turned on inside of Validate_Items and Next messages. Note: When this property is SET the Obvject_Validation property is also set. It is set TRUE if mode is set to VALIDATE_DEFAULT, else it is set False. It is not expected that you will dynamically change the Validate_Mode property. You'll probably set it once, when the object is created. 12/22/94 JJT - Added code from server.pkg to validate_items. 05/25/95 JJT - Created Object_item_Validation sets object_validation. ************************************************************************ 11/11/95 JJT - Validate Items now sends a smarter activate message Activate_area (also defined here). ************************************************************************

    1) If Validate_mode is SAVE or SAVE_NEXT then make sure that the validations occur (set object_validation to TRUE). If the mode is DEFAULT the property is probably already true. 2) Set Validate_All_Items_State to T. Validate handlers can query this property to determine if a validate is due to navigation or saving

    1) If Validate_mode is SAVE_NEXT then make sure that the validations occur (set object_validation to TRUE). If the mode is DEFAULT the property is probably already true. This insures that validates occur during "procedural" data-entry (pressing enter or tab) but not during event-driven data-entry
    • Integeroldval
  • Set(integer fg)
    Set object_validation. This is sent to the focus object through entry_clear/clear_all. All objects understand this message but only item based (entry_form and table) objects uses this. See Deodlgmx.pkg
