    <p>I have been around this problem for days now.I have written my code in constructor pattern for the first time.I want to extend the height of 10 bezier lines in transition.I have tried kineticjs(i failed),tried Setinterval(creates jerk in animation).So I finally resorted to requestAnimationFrame.But because of this constructor pattern,I am totally confused where to include it and what changes are to be made.</p> <p>This is what I have done so far---<a href="http://jsfiddle.net/jayeshjain24/UmSss/" rel="nofollow">JSFIDDLE</a></p> <p>So basically I will be extending my endY and cpY1 and cpy2 in transition.Onmouseover of canvas the height of all bezier lines must increase in transition giving it an animation like feel.</p> <p>JAVASCRIPT:</p> <pre><code>//for entire code please have a look at the fiddle.this is just 10% of my code //for simplification purpose,you can use 3 instances instead of 9!!! (function() { hair = function() { return this; }; hair.prototype={ draw_hair:function(a,b,c,d,e,f,g,h){ var sx =136+a;//start position of curve.used in moveTo(sx,sy) var sy =235+b; var cp1x=136+c;//control point 1 var cp1y=222+d; var cp2x=136+e;//control point 2 var cp2y=222+f; var endx=136+g;//end points var endy=210+h; var canvas = document.getElementById('myCanvas'); var context = canvas.getContext('2d'); context.strokeStyle="grey"; context.lineWidth="8"; context.beginPath(); context.moveTo(sx,sy); context.bezierCurveTo(cp1x,cp1y,cp2x,cp2y,endx,endy); context.lineCap = 'round'; context.stroke(); } }; })(); </code></pre>

    1. COI took your code and created a Hair "class" version complete with a constructor. You supply this class with the number of hairs you need and it draws/redraws all hairs as needed as a group. I did this to improve performance because the mousemove handler will only have to respond to 1 group instead of 9 individual objects. I also added a method on the class that causes the hair to grow. As we discussed, this is done by raising the "Y" coordinate of control points and the endpoint. Good luck with your project. :)

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.
