<p>Use <a href="http://www.lwjgl.org/javadoc/org/lwjgl/input/Keyboard.html#getEventKeyState%28%29" rel="nofollow"><code>Keyboard.getEventKeyState</code></a> to determine the current event, followed by <a href="http://www.lwjgl.org/javadoc/org/lwjgl/input/Keyboard.html#getEventKey%28%29" rel="nofollow"><code>Keyboard.getEventKey</code></a> to determine which key this is. Then, you need to make sure you disable repeat events via <a href="http://www.lwjgl.org/javadoc/org/lwjgl/input/Keyboard.html#enableRepeatEvents%28boolean%29" rel="nofollow"><code>Keyboard.enableRepeatEvents</code></a>. Maintain state for the current movement, changing based on these events, and every tick move accordingly. Something like the following, as quick sketch:</p> <pre><code>Keyboard.enableRepeatEvents(false); ... /* in your game update routine */ final int key = Keyboard.getEventKey(); final boolean pressed = Keyboard.getEventKeyState(); final Direction dir = Direction.of(key); if (pressed) { movement = dir; } else if (movement != Direction.NONE && movement == dir) { movement = Direction.NONE; } ... /* later on, use movement to determine which direction to move */ </code></pre> <p>In the above example, <code>Direction.of</code> returns the appropriate direction for the pressed key,</p> <pre><code>enum Direction { NONE, LEFT, RIGHT, DOWN, UP; static Direction of(final int key) { switch (key) { case Keyboard.KEY_A: return Direction.LEFT; case Keyboard.KEY_D: return Direction.RIGHT; case Keyboard.KEY_W: return Direction.UP; case Keyboard.KEY_S: return Direction.DOWN; default: return Direction.NONE; } } } </code></pre>

Guidance

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.
