Body
<p>This is a little more dynamic, object-oriented version, so you can configure the options as the circle radius, border width, colors, duration and step of animation, you can also animate the circle to a certain percentage. It was quite fun to write this.</p> <pre><code><canvas id="Circle" width="300" height="300"></canvas> <script> function Animation( opt ) { var context = opt.canvas.getContext("2d"); var handle = 0; var current = 0; var percent = 0; this.start = function( percentage ) { percent = percentage; // start the interval handle = setInterval( draw, opt.interval ); } // fill the background color context.fillStyle = opt.backcolor; context.fillRect( 0, 0, opt.width, opt.height ); // draw a circle context.arc( opt.width / 2, opt.height / 2, opt.radius, 0, 2 * Math.PI, false ); context.lineWidth = opt.linewidth; context.strokeStyle = opt.circlecolor; context.stroke(); function draw() { // make a circular clipping region context.beginPath(); context.arc( opt.width / 2, opt.height / 2, opt.radius-(opt.linewidth/2), 0, 2 * Math.PI, false ); context.clip(); // draw the current rectangle var height = ((100-current)*opt.radius*2)/100 + (opt.height-(opt.radius*2))/2; context.fillStyle = opt.fillcolor; context.fillRect( 0, height, opt.width, opt.radius*2 ); // clear the interval when the animation is over if ( current < percent ) current+=opt.step; else clearInterval(handle); } } // create the new object, add options, and start the animation with desired percentage var canvas = document.getElementById("Circle"); new Animation({ 'canvas': canvas, 'width': canvas.width, 'height': canvas.height, 'radius': 100, 'linewidth': 10, 'interval': 20, 'step': 1, 'backcolor': '#666', 'circlecolor': '#fff', 'fillcolor': '#339999' }).start( 70 ); </script> </code></pre>

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.
