    <p>I wrote a simple program with <strong>SFML</strong> and <strong>OpenGL</strong> which draws a spinning square that can be moved around the screen with the arrow keys.</p> <p>It works fine on all the Linux and Mac computers I've tested it on, but when I try to move the square on Windows (by holding down an arrow key) it moves a small distance and then stops moving and spinning. I'm pretty sure the program is getting stuck in the <code>GetEvent</code> method - my guess is that when I've held the key down long enough for it to start repeating, the event stack keeps getting new events added to it before I can pop everything off it (and if I turn the key repeat rate on Windows right down to the minimum then the problem goes away - I don't really like this as a solution though). </p> <p>I found that pressing and holding Alt, Ctrl, Delete, Page up, Page down, Home, End etc all cause this behavior too (even though I don't specifically detect any of these keys in the program), but all the letter keys, as well as space, enter, backspace and the keypad arrow keys work fine (i.e. they don't cause the program to pause if I hold them down for too long).</p> <p>I don't have the exact code (I just turned my laptop off), but it looks like:</p> <pre><code>while(running) { while(app.GetEvent(event)) if(event.Type==sf::Event::Closed) running=false; if(input.IsKeyDown(sf::Key::Right)); // move right // etc etc // update rotation // draw everything } </code></pre> <p>Any ideas as to what the exact problem might be, and how I could fix it?</p>

    1. COHave you tried storing keystates in booleans, then doing logic based on the boolean states? So . . . . . if(input.IsKeyDown(sf::Key::Right)) right = true; . . . . . . if(right) moveRight();

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.
