Class: Field_Attributes

Private: This replaces the use of arrays to get at this value. This allows us to find specific validation types (like checkboxes) more quickly than scanning an array

************************************************************************// Construct_object ype // Define storage for validation types. Access to storage is private. // ************************************************************************//

************************************************************************// Create_Items. // Set any defaults required by this class when the main file is created. // Create a string which contains all validation types. Set all to // No extended validation type. // ************************************************************************//

************************************************************************// Function Field_CheckBox_Value // Return the Value associated with the field and its select-state. // ************************************************************************//

************************************************************************// Get Field_error_Number // Get Field_error_Message // Used to retreive the error number and message for a particular field // ************************************************************************//

************************************************************************// Field_Fill_List // All extended validations know how to send callback messages (iMsg) to // the calling object (iObj). This allows external lists to get filled w/ // the contents of a range. Used by combo boxes, spinners, etc. // ************************************************************************//

************************************************************************// Procedure Field_fill_list_Field_Check // Callback to provide all valid value for this validation. // Call back with all valid check values // ************************************************************************//

************************************************************************// Procedure Field_fill_list_Field_Checkbox // Callback to provide all valid value for this validation. // Just call back with the two true and false values // ************************************************************************//

************************************************************************// Procedure Field_fill_list_Field_Range // Callback to provide all valid value for this validation. // Just call back with the two range values // ************************************************************************//

************************************************************************// Procedure Field_fill_list_Field_table // Callback to provide all valid value for this validation. // Pass the request on to the validation table. This is the most common // use of this. // ************************************************************************//

************************************************************************// Field_Table_Object // Return the id of the validation table if one exists. Otherwise return // a zero. // ************************************************************************//

************************************************************************// Get/Set Field_Validation_Type // Returns the extended validation type for the passed field. // ************************************************************************//

************************************************************************// Function Field_Value_Select_State // Return the select_state based on the passed value and field // ************************************************************************//

************************************************************************// Next_Validation_Type // Return field number of next field matching the passed validation type. // Pass validation type and last position checked. Return 0 if no match // ************************************************************************//

************************************************************************// Procedure Prompt_Object // Often extended valditation types can provide automatic prompt // objects. If the extended type supports a prompt object and there is // a global validation_list object, we will use it // ************************************************************************//

************************************************************************// Procedure Set Field_Error // This procedure will be called by the Extended_Data_Set to set the // errornumber and message which will be triggered when it needs to. // ************************************************************************//

************************************************************************// Procedure Set Field_Value_Range // Procedure to set the range for a field. It will automatically set the // validation type of the field as well. // ************************************************************************//

************************************************************************// Procedure Set Field_Value_Check // Procedure to set the check for a field. It will automatically set the // validation type of the field as well. // ************************************************************************//

************************************************************************// Procedure Set Field_CheckBox_Values // Procedure to set up a checkbox field. We will store the TRUE and FALSE // Values in the extended array. // ************************************************************************//

************************************************************************// Procedure Set Field_Value_Table // The object keeps track of a validation table object. This table object // can be any type of object must at a minimum understand a small message // protocol (see xvaltbl.pkg for info) // ************************************************************************//

************************************************************************// Validate_Field // This function manages the validation of a field against its extended // validations. // ************************************************************************//

************************************************************************// Validate_Field_Check // Function to check a fields value agains a given check string. // ************************************************************************//

************************************************************************// Validate_Field_Checkbox Check that the buffer value is one of the two checkbox values. // ************************************************************************//

************************************************************************// Validate_Field_Range // Function to check a fields value agains a given check string. // ************************************************************************//

************************************************************************// Validate_Field_Table // This valdates against a validation table if appropriate (if a table // exists and the table's validate_State is T). It validates by passing // the message validate_value to the validation table object // ************************************************************************//
