    <p>Let's say I have two base abstract classes with completely different functionality: Laptop and Smartphone. (Suppose the functionality is completely different). And in my current project I had already many implementations of laptops and smartphones, and they always were completely different.</p> <p>But suddenly I received a request to add a class that is an implementation of pc-tablet, that is actually have functions of both smartphone and laptop. It is too late to change the base classes, and actually I'm very sure that this pc-tablet will appear only once.</p> <p>The problem is, I should be able to contain my pc-tablet in the conainer for smartphones, but it should also be laptop, because of the inherited functionality (actually beside that, in some part of the project pc-tablet is used only as laptop, and it doesn't need smartphone functionality. Moreover it is bad to look at pc-tablet as smartphone for that particular part of the project). So I have PcTabletAsLaptop : Laptop class, that is actually a laptop, and not a smartphone.</p> <p>My solution is to add a wrapper:</p> <pre><code>class PcTablet : SmartPhone { private PcTabletAsLaptop _pcTablet; // Here goes all the methods of PcTabletAsLaptop as proxies: public void Call(int number) { _pcTablet.Call(number); } // ..... } </code></pre> <p>There are 200+ methods and I want them to be generated automatically from PcTabletAsLaptop.</p> <p>This solution looks quite complicated. My question is it good, or maybe there are some simplier ways to do that?</p>

    1. COCan you not add a further base class "MobileDevice" and have them all inherit from that?

    3. CO@DaveBish I do not want to change original hierarchy, as the project is already in production. Actually, this is a requirement from customer (we are writing framework, so code design is considered as part of the requirement too)

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.
