780,051 | 780,052 | defining hash in tr1 for a template class | <p>I have the class Gateway.
I need to store object of this class in a hash table (using tr1::unordered_set).
I've used both the unorderd_set and the class Gateway in another context and they work fine, yet I can't figure how to put a gateway in a unordered set because I can't define its <code>hash</code> function in tr1's namespace.</p>
<p>I've tried: (and many other variants)</p>
<pre><code>namespace std {
namespace tr1 {
template<> <typename T> inline size_t hash<(typename Gateway<T>)>::operator()(Gateway<T> gT) const {
return gT.getCore()->hash(); //!DOESN't WORK
}
}
</code></pre>
<p>The compiler says the this (<code>typename Gateway<T></code>) is wrong. If i take the <code>()</code> off, it assumes the <code>>></code> in the end of <code>hash<typename Gateway<T>>()</code> is the output stream.</p>
<p>While in the past i've done this</p>
<pre><code>namespace std {
namespace tr1 {
template<> inline size_t hash<Board>::operator()(Board b) const {
return b.hash(); //!WORKS FINE
}
}
}
</code></pre>
<p>Can anyone shed some light on the problem?</p>
<p><strong>Update</strong></p>
<p>Thanks for the answer yet there is still a problem The compiler says invalid use of incomplete type <code>struct std::tr1::hash<></code></p>
<p>This sort of error happens when we use the class without its complete definition, yet the class is fully defined before the declaration. I've already used this without templates in a very similar fashion without a problem.</p>

<p>I needed to create a concreate class based on third-party abstract base class. As always, I told Visual Studio to implement abstract base class, which it did, but the code didn't compile complaining about missing getter. However, event after adding getter manualy, the code still didn't compile. It turned out that this getter is internal. Funny thing about internal property is that it's not shown in metadata (View Definition). Vendor will make it protected in the next release, but at the time being, unless I'm missing some other way, there is nothing I can do about it, right?</p>

<p><strong>Original Post:</strong>
I am wondering why my <code>ListView</code> is not fading the top or bottom of my list. I have a feeling that because I have made a custom <code>ListItem</code>, that it ignores any fading that the <code>ListView</code> is trying to do.</p>
<p>I have tried:</p>
<ul>
<li>manually setting fading edge to <code>vertical</code> for moth the <code>ListItem</code> and the <code>ListView</code></li>
<li>setting the fading edge length to some value to see if it was defaulting to 0 for some reason.</li>
</ul>
<p>Is there something I need to implement in my <code>ListItem</code> to allow it to fade properly? Here is a picture of my <code>ListItem</code>. It has a 9-patch background image, a few <code>TextView</code>s, and a <code>ProgressBar</code>. Some of the <code>TextView</code>s have a custom font applied to them in code.</p>

But I thought that object's clone doesn't do anything.<br>

<p>I know I'm still a beginner because simple things still perplex me but every book I read for beginners honestly just rehashes what I do already know but every 'more advanced' book doesn't really allow me to learn, they depend on example files and I never really understand why they built 'said' function or 'said' class. So onto my question...</p>
<p>Is there any recommendations on a book or ANYTHING that pushes me out of this stage, I've used head first and normally they are really good but my issue there is they have me back tracking just to move forward again, It worked in HTML but its confusing in Python, basically I think I need to build a program while following along, Again I like HeadFirst's style but I need something that isn't going to make me have to remember one thing just to forget it...</p>
<p>for record, I've checked into some O'Reilly books</p>
