    <p>I'm trying to write a 3d environment with FirstPersonControls.js for the movement and the following for the mouseclick listener:</p> <pre><code>function onDocumentMouseDown(event) { event.preventDefault(); var vector = new THREE.Vector3((event.clientX / window.innerWidth) * 2 - 1, -(event.clientY / window.innerHeight) * 2 + 1, 0.5); projector.unprojectVector(vector, camera); var raycaster = new THREE.Raycaster(camera.position, vector.sub(camera.position).normalize()); var intersects = raycaster.intersectObjects(adblocks); if (intersects.length &gt; 0) { intersects[0].object.material.color.setHex(Math.random() * 0xffffff); } } </code></pre> <p>and in init():</p> <pre><code>document.addEventListener('mousedown', onDocumentMouseDown, false); </code></pre> <p>I've done this on another document and it worked fine, however, this time I'm trying to include FirstPersonControls.js.</p> <p>In FirstPersonControls.js, I disabled the mousedown and mouseup listeners, by commenting out the listeners, like this:</p> <pre><code>//this.domElement.addEventListener( 'mousedown', bind( this, this.onMouseDown ), false ); //this.domElement.addEventListener( 'mouseup', bind( this, this.onMouseUp ), false ); </code></pre> <p>That worked fine. FirstPersonControls.js works fine by itself. However, when I add the extra listener for the MouseDown event, the key input (w, a, s, d, q, r, and f) stops responding. If I hold down a key immediately at page load, that key will work until I stop, then everything stops responding. Also, another thing I don't understand, and this may be related, which is why I'm mentioning it, is if I comment out this line in FirstPersonControls.js:</p> <pre><code>this.domElement.addEventListener( 'mousemove', bind( this, this.onMouseMove ), false ); </code></pre> <p>Nothing is changed. Everything keeps functioning exactly the same, which doesn't make sense to me, because I thought that's where the mousemovement event is binded to the document.</p>

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
