Body
<p>I have adopted the code from Mason, did the reader exercise, and put it in a separate unit:</p> <pre><code>unit uJSONTools; interface Uses Classes, SysUtils, DBXJSON; procedure PrettyPrintJSON(JSONValue: TJSONValue; OutputStrings: TStrings; indent: integer = 0); // Formats JSONValue to an indented structure and adds it to OutputStrings implementation const INDENT_SIZE = 2; procedure PrettyPrintPair(JSONValue: TJSONPair; OutputStrings: TStrings; last: boolean; indent: integer); const TEMPLATE = '%s : %s'; var line: string; newList: TStringList; begin newList := TStringList.Create; try PrettyPrintJSON(JSONValue.JsonValue, newList, indent); line := format(TEMPLATE, [JSONValue.JsonString.ToString, Trim(newList.Text)]); finally newList.Free; end; line := StringOfChar(' ', indent * INDENT_SIZE) + line; if not last then line := line + ','; OutputStrings.add(line); end; procedure PrettyPrintArray(JSONValue: TJSONArray; OutputStrings: TStrings; last: boolean; indent: integer); var i: integer; begin OutputStrings.add(StringOfChar(' ', indent * INDENT_SIZE) + '['); for i := 0 to JSONValue.size - 1 do PrettyPrintJSON(JSONValue.Get(i), OutputStrings, indent + 1); OutputStrings.add(StringOfChar(' ', indent * INDENT_SIZE) + ']'); end; procedure PrettyPrintJSON(JSONValue: TJSONValue; OutputStrings: TStrings; indent: integer = 0); var i: integer; begin if JSONValue is TJSONObject then begin OutputStrings.add(StringOfChar(' ', indent * INDENT_SIZE) + '{'); for i := 0 to TJSONObject(JSONValue).size - 1 do PrettyPrintPair(TJSONObject(JSONValue).Get(i), OutputStrings, i = TJSONObject(JSONValue).size - 1, indent + 1); OutputStrings.add(StringOfChar(' ', indent * INDENT_SIZE) + '}'); end else if JSONValue is TJSONArray then PrettyPrintArray(TJSONArray(JSONValue), OutputStrings, i = TJSONObject(JSONValue).size - 1, indent + 1) else OutputStrings.add(StringOfChar(' ', indent * INDENT_SIZE) + JSONValue.ToString); end; end. </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
