Body
<pre><code>CCString *s_piece__locks = "TEST"; cocos2d::CCString *s_piece__locks2 = "TEST"; </code></pre> What the heck is this supposed to do? Declaring a pointer does not generate any object except the pointer itself. So basically, for this to "work", there would need to be another <code>CCString</code> object around already, that happens to represent the string "TEST". But even if that's given, how is C++ supposed to know which one to point to? It would need to look <code>"TEST"</code> up in some kind of e.g. hash map. None of this makes any sense. Change your code to either <ul> <li>Direct use of object on stack: <pre><code>cocos2d::CCString s_piece; s_piece = "TEST"; </code></pre></li> <li>Assigning new content to an object that resides somewhere else. You'd normally use a reference for this, e.g. <pre><code>void assign_test_to(cocos2d::CCString& target) { target = "TEST"; } </code></pre> it's also possible with a pointer <pre><code>void assign_test_to_ptr(cocos2d::CCString* target) { *target = "TEST"; } </code></pre> but don't do that unless you have a specific reason to.</li> </ul> In principle, there's another possibility: <pre><code>cocos2d::CCString* s_piece_locks = new CCString; *s_piece_locks = "TEST"; </code></pre> but you want to avoid this, as it can very easily lead to memory leaks. What would be ok is <pre><code>std::unique_ptr<cocos2d::CCString> s_piece_locks = new CCString; *s_piece_locks = "TEST"; </code></pre>

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.
