    <p>Okay, sample code first; this is my attempt at communicating what it is that I'm trying to do, although it doesn't compile:</p> <pre><code>#include &lt;iostream&gt; template &lt;class T&gt; class Base { public: virtual void my_callback() = 0; }; class Derived1 : public Base&lt;int&gt; , public Base&lt;float&gt; { public: void my_callback&lt;int&gt;() { cout &lt;&lt; "Int callback for Derived1.\n"; } void my_callback&lt;float&gt;() { cout &lt;&lt; "Float callback for Derived\n"; } }; class Derived2 : public Base&lt;int&gt; , public Base&lt;float&gt; { public: void my_callback&lt;int&gt;() { cout &lt;&lt; "Int callback for Derived2.\n"; } void my_callback&lt;float&gt;() { cout &lt;&lt; "Float callback for Derived2\n"; } }; int main() { { Derived1 d; Base&lt;int&gt; * i_p = d; Base&lt;float&gt; * i_f = d; i_p-&gt;my_callback(); i_f-&gt;my_callback(); } { Derived2 d; Base&lt;int&gt; * i_p = d; Base&lt;float&gt; * i_f = d; i_p-&gt;my_callback(); i_f-&gt;my_callback(); } //Desired output: // Int callback for Derived1. // Float callback for Derived1 // Int callback for Derived2. // Float callback for Derived2 system("Pause"); } </code></pre> <p>So, what I'm trying to do is to make a sort of wrapper class to inherit from that will automatically connect the derived class to various callback lists; it needs to connect a specific instance of the derived class to the list, and I want the "user" to have / get to make the callback functions as part of making the derived class, as you can see. </p> <p>It seems like this should be able to work, although I may need to use a different syntax. If it can't work, do you have any suggestions?</p>

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.
