    <p>I have a bit of a problem with inheritance of delegates. Delegate as far as i understand is a pointer to a pair: an instance and a method, the thing is this is the method referenced in the creation of the delegate, and not affected by inheritance. So, this won't work:</p> <pre><code>public class BaseObject { public delegate void del(); public BaseObject() { next=Method; } public del next; public void ExecuteNext() { next(); } public virtual void Method() { Debug.Log("BASE"); } } public class InheritedObject:BaseObject { override public void Method() { Debug.Log("INHERITED"); } } ... (new InheritedObject()).ExecuteNext(); </code></pre> <p>Execute runs the base Method(), I want it to run the inherited Method(). I have found some way around, but it is inefficient, distracting and very error prone, anyway here's the current working version that I'd like to get rid of:</p> <pre><code>class BaseObject { public delegate void del(); BaseObject() { next=DoMethod; /// using DoMethod here } public del next; public void ExecuteNext() { next(); } public void DoMethod() { /// using DoMethod here Method(); } public virtual void Method() { // do base } } class InheritedObject:BaseObject { override public void Method() { // do inherited } } ... (new InheritedObject()).Execute(); </code></pre> <p>This DoMethod aproach works but has many problems, </p> <ol> <li>lots of useless code</li> <li>error prone when using the class - easy to mistake obj.next=<code>DoMethod</code> with obj.next=<code>Method</code></li> <li>error prone when inheriting the class - I have to remember to not to inherit the DoMethod, and lots of virtual and overrides.</li> </ol> <p>Any suggestions how can I do that better? Perhaps some annotation magic that does the <code>DoMethod</code> by itself? I've already thought of dictionaries - they aren't good here, they add even another level of confusion (Mono, .NET 2, Unity3d framework)</p>

    1. COYou could start with the reasoning behind this approach. Why do you need the delegate at all?

    2. CO`(new InheritedObject()).Method();` works. As Daniel said, why the `delegate`?

    3. COThis is just a minimal code example, in real usage this construct is a multi level inherited state machine for game logic of a character.

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.
