Revision 1.1 1992/09/08 14:43:05 james Initial revision Revision 1.7 92/06/20 04:21:14 lee altered wrapping to 1) ignore wrap_state, and 2) only save if not a child of a deo (child_wrapping will save if it's a child of a deo).

Revision 1.5 92/06/03 15:17:29 steve-l altered Child_Wrapping for proper argument dereferencing Revision 1.4 92/06/03 15:09:53 steve-l added WRAPPING function Revision 1.3 92/05/14 15:46:18 unknown Updated Copyright slug - SWM.

Lowe This module defines the messages and properties required to support the data-editing standard for data-entry objects, collected in the abstract class Find_Edit_Mixin. This file should be USEd prior to and IMPORTed within the scope of the class definition by any user-interface (esp. data-entry) class which must support the data-entry object standards. This file is used by ENTRYFRM.PKG, TEXT_WIN.PKG, and TABLE.PKG. ************************************************************************/

  • define_find_edit()
    Description This procedure defines the accelerator keys and properties required to support the data-editing standard for data-entry objects. This includes accelerator keys to support the finding, clearing, saving, and deleting of database records, and two properties governing certain automatic functions of editing (see Notes). Assumptions/Preconditions This procedure should only be called from within the Construct_Object procedure of a class definition. Exceptions None. Notes The Auto_Save_State property governs whether a Save is automatically issued upon rotation wrap-around (from the last object/item to the first object/item). The Auto_Clear_DEO_State property governs whether a Clear is automatically issued after a successful Save or Delete operation.
    • IntegerAuto_Save_State
    • IntegerAuto_Clear_DEO_State
  • Find_GE()
    Description This procedure finds greater-than-or-equal-to using the file and field, if any, of the current item. Assumptions/Preconditions None. Exceptions None. Notes Depends entirely upon Request_Find.
  • Find_Next()
    Description This procedure finds greater-than using the file and field, if any, of the current item. Assumptions/Preconditions None. Exceptions None. Notes Depends entirely upon Request_Find.
  • Find_Previous()
    Description This procedure finds less-than using the file and field, if any, of the current item. Assumptions/Preconditions None. Exceptions None. Notes Depends entirely upon Request_Find.
  • Find_First()
    3/22/2002: Added find_first and Find_last. Previously this was accomplished by sending beginning_of_data and end_of_data. The problem with that message is that it had multiple meaning. In a edit or grid, it means go to top/bottom of file. In forms, it means first last record. Since we can not change this without breaking existing programs we will create a message that *always* does a find first/last record. This can be used in tool bars (or anywhere) to consistently provide the same behavior.
  • Find_Last()
  • SuperFind()
    Description This procedure superfinds greater-than-or-equal-to using the file and field, if any, of the current item. Assumptions/Preconditions None. Exceptions None. Notes Depends entirely upon Request_SuperFind.
  • SuperFind_Next()
    Description This procedure superfinds greater-than using the file and field, if any, of the current item. Assumptions/Preconditions None. Exceptions None. Notes Depends entirely upon Request_SuperFind.
  • SuperFind_Previous()
    Description This procedure superfinds less-than using the file and field, if any, of the current item. Assumptions/Preconditions None. Exceptions None. Notes Depends entirely upon Request_SuperFind.
  • IntegerWrapping()
  • BooleanDeo_Find_Object()
    Returns True to indicate that this DEO supports the Find mixin protocol. This is used by menu items to determine if you are within a DEO control finding obejct and should therefore send a DEO message.
