    <p>Just finding my way around templates so was trying out a few stuff.</p> <p>Let me know what I am doing wrong here.</p> <p>I am trying to overload a inherited templates virtual method. </p> <pre><code>// class templates #include &lt;iostream&gt; using namespace std; template &lt;class T, class A&gt; class mypair { T a, b; public: mypair (T first, T second) {a=first; b=second;} virtual A getmax (); }; template &lt;class T, class A&gt; A mypair&lt; T, A&gt;::getmax () { A retval; retval = a&gt;b? a : b; return retval; } template &lt;class T, class A&gt; class next : public mypair &lt;T, A&gt; { A getmax () { cout &lt;&lt;" WHOO HOO"; } }; int main () { mypair &lt;double,float&gt; myobject(100.25, 75.77); next&lt;double,float&gt; newobject(100.25, 75.77); cout &lt;&lt; myobject.getmax(); return 0; } </code></pre> <p>`</p> <p>This gives the error :</p> <pre><code>function.cpp: In function ‘int main()’: function.cpp:35: error: no matching function for call to ‘next&lt;double, float&gt;::next(double, double)’ function.cpp:25: note: candidates are: next&lt;double, float&gt;::next() function.cpp:25: note: next&lt;double, float&gt;::next(const next&lt;double, float&gt;&amp;) </code></pre> <p>If this isnt the right way to proceed, some info on template inheritance would be great</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.
