    <p><a href="http://doc.qt.nokia.com/latest/threads-qtconcurrent.html" rel="nofollow noreferrer"><code>QtConcurrent</code></a> is awesome.</p> <p>I'll let the Qt docs speak for themselves:</p> <blockquote> <p>QtConcurrent includes functional programming style APIs for parallel list processing, including a MapReduce and FilterReduce implementation for shared-memory (non-distributed) systems, and classes for managing asynchronous computations in GUI applications.</p> </blockquote> <p>For instance, you give <code>QtConcurrent::map()</code> an iterable sequence and a function that accepts items of the type stored in the sequence, and that function is applied to all the items in the collection. This is done in a multi-threaded manner, with a thread pool equal to the number of logical CPU's on the system. </p> <p>There are plenty of other function in <code>QtConcurrent</code>, like <code>filter()</code>, <code>filteredReduced()</code> etc. The standard CompSci map/reduce functions and the like.</p> <p>I'm totally in love with this, but I'm starting work on an OSS project that will not be using the Qt framework. It's a library, and I don't want to force others to depend on such a large framework like Qt. I'm trying to keep external dependencies to a minimum (it's the decent thing to do).</p> <p>I'm looking for a generic C++ framework that provides the same/similar high-level primitives that <code>QtConcurrent</code> does, and that works with STL collections. AFAIK <code>boost</code> has nothing like this (I may be wrong though). <code>boost::thread</code> is very low-level compared to what I'm looking for (but if the requested lib used <code>boost::thread</code> for the low-level work, that would be great).</p> <p>I know C# has something very similar with their Parallel Extensions so I know this isn't a Qt-only idea.</p> <p>What do you suggest I use?</p>

    1. COQtConcurrent is cool. I adapted the Mandelbrot example to use a parallel interface...might interest you: http://hostilefork.com/thinker-qt/

    2. CO@Hostile Yes, QtConcurrent is cool. As I've said, I'm using it all the time. I'm just looking for something like it that works with STL collections and without Qt itself.

    3. COI may be wrong, but I thought the modularity of Qt would mean that you have to use at most only QtCore and QtConcurrent (and not "such a large framework as Qt")?

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.
