    <p>In the interest of full disclosure, I wrote the following tool. I apologize if this reads like an advertisement.</p> <p>You can use the <a href="https://bitbucket.org/alfonse/glloadgen/wiki/Home" rel="noreferrer">OpenGL Loader Generator</a>. It's a tool that generates headers and source files for loading OpenGL functions. You specify which extensions and OpenGL versions you're interested in, and it only outputs the enums and functions for those versions. That's the primary feature of the tool: getting clean headers and source files that only contain the stuff you intend to use.</p> <p>But the secondary feature is that it has different styles of generation. These styles define the specifics of how the output is generated.</p> <p>The <a href="https://bitbucket.org/alfonse/glloadgen/wiki/Style_Pointer_C" rel="noreferrer">standard "pointer_c" style</a> generates code that looks a lot like GLEW, where the functions are <code>#define</code>s. That is actually <em>essential</em> in C, because you can't redefine globally accessible variables/function names. So you can't define a function pointer that has the same name as a non-pointer function. Such as <code>glVertex3f</code>; that name is already defined by the OpenGL library on some platforms, so you can't define a new version of it. You have to <code>#define</code> around it.</p> <p>C++ on the other hand has namespaces. So in <a href="https://bitbucket.org/alfonse/glloadgen/wiki/Style_Pointer_CPP" rel="noreferrer">the "pointer_cpp" style</a>, you get C++ headers and source that puts most of OpenGL in the <code>gl</code> namespace. This also means that the Pointer CPP style doesn't have to use #defines. So it doesn't. <code>gl::Vertex3f</code> is a function pointer with real argument types and names. Any decent code completion tool should be able to understand these.</p> <p><a href="https://bitbucket.org/alfonse/glloadgen/wiki/Style_No_Load_CPP" rel="noreferrer">The "noload_cpp" style</a> does the same thing. The difference is that there's no initialization function you have to call; you can call any function pointer and it will dynamically load that function if it hasn't been loaded already.</p> <p>Spurred by this discussion, I have released a version of the tool that includes <a href="https://bitbucket.org/alfonse/glloadgen/wiki/Style_Function_CPP" rel="noreferrer">the func_cpp style</a>. This uses inline functions to forward calls to the function pointers. This is directly using functions, so if it can't parse these, then there's no hope for your autocompletion tool.</p>

    1. COSo if I use this, and use pointer_cpp style or noload_cpp style I can get argument completion with clang_complete? Because basically what clang_complete uses is clang on the fly and generates completion just from using the compiler, which is why GLEW didn't want to show any argument completion because it wasn't defining any arguments.

    2. CO@zero57: Well I can't *guarantee* it, as I've never used Clang for content completion. But those styles generate explicit function pointers, not `#define`s. So you've got a much better chance of it working. For what it's worth, VS2008 seems to work on it.

    3. COSo I tried using OpenGL Loader Generator, but it just didn't work for me, I tried all styles but unfortunately it didn't want to autocomplete. I did like the idea though, however. It basically removes all deprecated features with ease.

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.
