    <p>You have to use <code>static_cast</code>:</p> <pre><code>event_t evt = static_cast&lt;event_t&gt;(&amp;SpecificClass::onBar); </code></pre> <p>This is because it is slightly dangerous to cast to <code>event_t</code>, you could accidently apply it to a <code>BaseClass</code> instance.</p> <p><strong>How it works (for the skeptical):</strong></p> <pre><code>class BaseClass { public: typedef void (BaseClass::*callback_t)(); // callback method void doSomething(callback_t callback) { // some code this-&gt;*callback(); // more code } void baseCallback(); // an example callback }; class DerivedClass : public BaseClass { public: void derivedCallback(); void doWhatever() { // some code doSomething(&amp;BaseClass::baseCallback); // more code doSomething(static_cast&lt;callback_t&gt;(&amp;DerivedClass::derivedCallback)); // et cetera }; </code></pre> <p>Here is what you should <strong>avoid,</strong> and why this is potentially dangerous:</p> <pre><code>void badCodeThatYouShouldNeverWrite() { BaseClass x; // DO NOT DO THIS IT IS BAD x.doSomething(static_cast&lt;callback_t&gt;(&amp;DerivedClass::derivedCallback)); } </code></pre> <p>The requirement for a <code>static_cast</code> makes it so you can't "accidentally" pass <code>DerivedClass</code> method pointers in. And if you think this is dangerous, just remember that it's a pointer, and pointers are always dangerous. Of course, there are ways you can do this that involve creating helper classes, but that requires a lot of extra code (possibly making a class for every function you want to pass as a callback). Or you could use closures in C++11, or something from Boost, but I realize that a lot of us do not have that option.</p>

    1. COI'm pretty sure that's not legal C++. I'm not certain, but I don't think you can cast member pointers like that, nor can you later call them through the base class, unless the member is _in_ the base class.

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.
