Body
After asking my <a href="https://stackoverflow.com/questions/8982376/interfacing-with-super-and-subclass-constructors/" title="previous question">previous question</a> I have come to a situation where I use a couple of object classes stored in each other's properties to retain access to several fields and methods. For example <pre><code>classdef Class1 properties Class1Prop % A property accessible from Class1 Class2 % A cell array of class 2 objects end methods % Construct the class with all of its properties function self = Class1() end function Class1Method self.Class1Prop = ... end end end </code></pre> I populate an object of Class1 that contains a cell array of Class2. Now I would like to have methods change the values of properties inside of this object. i.e. <pre><code> Class1{index}.Class2{index}.Class2Method </code></pre> Will perform some computation and now have that value stored somewhere in that instance of the class. As stated in the matlab documentation: <blockquote> "If a function modifies a handle object passed as an input argument, the modification affects the object referenced by both the original and copied handles." </blockquote> To gain the functionality I want, I have to use value classes (with methods that return the class object) so that the value returned by the method call is changed. The value returned can be assigned as well: <pre><code>Class1{index}.Class2{index} = Class1{index}.Class2{index}.Class2Method </code></pre> However, ideally <pre><code>Class1{index}.Class2{index}.Class2Method </code></pre> would update the Class2 properties. And that is the functionality I want. Is this possible?

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.
