<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;"><p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">This isn't the proper way to do private classes.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Private classes are done like this:</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">1) In the header:</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;"><div class="codehilite" style="background: #f8f8f8"><pre style="line-height: 125%"><span style="color: #008000; font-weight: bold">private</span><span style="color: #666666">:</span>
struct ExternalExtractorPrivate<span style="color: #666666">;</span>
ExternalExtractorPrivate <span style="color: #666666">*</span>d_ptr<span style="color: #666666">;</span>
Q_DECLARE_PRIVATE<span style="color: #666666">(</span>ExternalExtractor<span style="color: #666666">);</span>
</pre></div>
</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Basically, the private class should be named ParentClassPrivate, the next line should create a ParentClassPrivate pointer called d_ptr (the variable name is important), and then you use the Q_DECLARE_PRIVATE(ParentClass) macro call (not ParentClassPrivate) to set up the accessor.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">I've used the struct keyword instead of class because everything inside the public class is typically public - and in C++ structs are just classes where everything is public by default.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Doing it this way is better because the macros take care of casting the pointer correctly - suppose someone subclasses ParentClass to ChildClass, raw pointers won't work because it's still a pointer to ParentClass::Private, not ChildClass::Private.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">2) When you use the d-pointer inside a function, do this:</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;"><div class="codehilite" style="background: #f8f8f8"><pre style="line-height: 125%">someFunc()
{
Q_D(ParentClass) // not ParentClassPrivate
d->whatever = whatever;
}
</pre></div>
</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Note that you're using d-> and not d_ptr->. The Q_D() macro automatically static_casts() the d_ptr into the appropriate type and makes a variable d (local to your function) that you can use to access the private class.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">For more information, refer to:
