Re: Change a Property of an Item

Hi !

I suppose you are using developer/2000 (?!?!?). To change the enabled (or any other) property for some item, you have to use the Set_Item_Property() function ...

Something like this

  Enable:
  Set_Item_Property('MYBUTTON',ENABLED,PROPERTY_TRUE);

  Disable:
  Set_Item_Property('MYBUTTON',ENABLED,PROPERTY_FALSE);

For some edit field you may have to set the navigable/updateable properties also to allow focus on these fields ...

  Set_Item_Property('MYFIELD',UPDATEABLE,PROPERTY_TRUE);   Set_Item_Property('MYFIELD',NAVIGABLE,PROPERTY_TRUE);

I have actually used functions (below) to enable/disable or show/hide items.

FUNCTION DisableItem( ItemName VARCHAR2 ) RETURN BOOLEAN IS   DItem Item;

BEGIN
  DItem := Find_Item(ItemName);
  If Not Id_Null(DItem) Then
    If Get_Item_Property(DItem,ENABLED) = 'TRUE' Then       Set_Item_Property(DItem,ENABLED,PROPERTY_FALSE);

-- Enable ...
--    If Get_Item_Property(DItem,ENABLED) = 'FALSE' Then
--      Set_Item_Property(DItem,ENABLED,PROPERTY_TRUE);

    End If;
  Else
    Return FALSE;
  End If;

  Return TRUE;
END; Tom Söderberg
