    <p>A possible solution:</p> <pre><code>#include &lt;iostream&gt; #include &lt;type_traits&gt; class A { public: //... static const char fooString[]; }; const char A::fooString[] = "This is a Foo."; class B { public: //... static const char barString[]; }; const char B::barString[] = "This is a Bar."; class C { public: //... static const char fooString[]; }; const char C::fooString[] = "This is also a Foo."; void doFoo(const char*s) { std::cout &lt;&lt; "doFoo: " &lt;&lt; s &lt;&lt; "\n"; } void doBar(const char*s) { std::cout &lt;&lt; "doBar: " &lt;&lt; s &lt;&lt; "\n"; } template&lt;class T&gt; class Something { public: //This version should be called if T has a static member called "fooString", //so it should be called if T is either class A or C template &lt;typename TT = T, typename std::enable_if&lt;TT::fooString != 0, bool&gt;::type = false&gt; void doSomething() { doFoo(T::fooString); } //This version should be called if T has a static member called "barString", //so it should be called if T is class B template &lt;typename TT = T, typename std::enable_if&lt;TT::barString != 0, bool&gt;::type = false&gt; void doSomething() { doBar(T::barString); } }; int main() { Something&lt;A&gt; a; Something&lt;B&gt; b; Something&lt;C&gt; c; a.doSomething(); //should call doFoo(A::fooString) b.doSomething(); //should call doBar(B::barString) c.doSomething(); //should call doFoo(C::fooString) } </code></pre> <p>Output:</p> <pre><code>doFoo: This is a Foo. doBar: This is a Bar. doFoo: This is also a Foo. </code></pre>

    1. COIt won't compile for me, it says that default template arguments can only be used on class templates. However, I've never heard of the type_traits header and it sounds promising, I'll try to look into it.

    2. COThe solution needs a compiler with C++11 support, gcc 4.7 for example. `type_traits` is new, and using function template default arguments is now allowed.

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
