    <p>I think you should follow up on your idea of giving the TSomething class serialization methods of it's own.</p> <p>Here's an example, using XML for serialization:</p> <pre><code>TSomething = class(TPersistent) protected FNumber: Integer; FLine: String; public procedure WriteToXmlNode(XmlNode: IXmlNode); procedure ReadFromXmlNode(XmlNode: IXmlNode); published property Number: Integer read FNumber write FNumber; property Line: String read FLine write FLine; end; TOther = class(TPersistent) protected FSomething: TSomething; public procedure WriteToXmlNode(XmlNode: IXmlNode); procedure ReadFromXmlNode(XmlNode: IXmlNode); published property Something: TSomething read FSomething write FSomething; end; </code></pre> <p>In other words, letting each of the classes know how to serialize themselves to XML.</p> <p>The write method of TOther will then look like this:</p> <pre><code>procedure TOther.WriteToXmlNode(XmlNode: IXmlNode) var ChildNode: IXmlNode; begin // Write something ChildNode := XmlNode.AddChild('Something'); Something.WriteToXmlNode(ChildNode); end; </code></pre> <p>And the read method will look like this:</p> <pre><code>procedure TOther.ReadFromXmlNode(XmlNode: IXmlNode) var ChildNode: IXmlNode; begin // Read ChildNode := XmlNode.ChildNodes.First; while Assigned(ChildNode) do begin // Read something if ChildNode.NodeName = 'Something' then Something.ReadFromXmlNode(ChildNode); // Next child node ChildNode := ChildNode.NextSibling; end; end; </code></pre> <p>That's the general gist of it. </p> <p>I think you'll be using a similar approach in your example, even if you do not choose to serialize to XML.</p> <p><strong>Edit</strong>: It was a bit unclear what you wanted in your question. If you're writing components, and you want the properties of the components to be properly serialized when you work with them at design time, this is not the way to go. The method I describe is for serializing arbitrary objects during runtime.</p>

    1. COthis is all fine and dandy but i think that following Tony Hopkinons's suggestion, I might sa aswell not reinvent a weel and use `TPersistent ` forj all my serialization needs. As I said, because I don't know any better I started from `TObject`, but since something other might have that, I might as well use the framework that already exists. The question that I'm asking is as much about improving what I have written (BORROWED) as it is about alternative and better solutions to my issue.

    2. CO@Raith Yes, you can proceed in the direction that you're going, and use Delphi's TWriter and TReader classes for serialization. If you do that, you need to handle the property type tkClass, as someone else suggested. Personally I prefer to reinvent the wheel in cases like this, for portability reasons.

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.
