<p>The jCrop plugin does most of the work. You just need a little logic to stitch it together with a slider widget (like the jqueryui slider).</p> <p>Here's a quick and dirty example. You'll certainly want to host the files on your own server, but I just wanted to throw something together.</p> <p>One significant difference is that this code forgets where you have dragged the selection and just resizes it around the current midpoint. If that is important to you, you could probably add that functionality pretty easily.</p> <pre> <html> <head> <link type="text/css" href="http://jqueryui.com/latest/themes/base/ui.all.css" rel="stylesheet" /> <script type="text/javascript" src="http://jqueryui.com/latest/jquery-1.3.2.js"></script> <script type="text/javascript" src="http://jqueryui.com/latest/ui/ui.core.js"></script> <script type="text/javascript" src="http://jqueryui.com/latest/ui/ui.slider.js"></script> <script type="text/javascript" src="http://jqueryui.com/latest/ui/ui.slider.js"></script> <script type="text/javascript" src="http://deepliquid.com/projects/Jcrop/js/jquery.Jcrop.js"></script> <link rel="stylesheet" href="http://deepliquid.com/projects/Jcrop/css/jquery.Jcrop.css" type="text/css" /> <style type="text/css"> #slider { margin: 10px; } </style> <script type="text/javascript"> var jcrop_api; $(document).ready(function(){ imgwidth = $("#cropbox").width(); imgheight = $("#cropbox").height(); aspectRatio=(imgheight > 0)?imgwidth / imgheight:1; jcrop_api = $.Jcrop('#cropbox',{ setSelect: [ 0, 0, imgwidth, imgheight ], aspectRatio: aspectRatio }); $("#slider").slider({ min: 0, max: 100, value: 100, slide: function(e,ui){ updateCrop(ui.value); } }); function updateCrop(size){ size = size / 100; maxX = $("#cropbox").width(); maxY = $("#cropbox").height(); midX = ((jcrop_api.tellSelect().x2 - jcrop_api.tellSelect().x) / 2) + jcrop_api.tellSelect().x; midY = ((jcrop_api.tellSelect().y2 - jcrop_api.tellSelect().y) / 2) + jcrop_api.tellSelect().y; midX = (midX < 0) ? midX * -1 : midX; midY = (midY < 0) ? midY * -1 : midY; sizeX = $("#cropbox").width() * size; sizeY = $("#cropbox").height() * size; x = midX - (sizeX/2); y = midY - (sizeY/2); x2 = midX + (sizeX/2); y2 = midY + (sizeY/2); // edge conditions if (x < 0){ x2 -= x2 - x; x = 0; if (x2 > maxX) x2 = maxX; } if (x2 > maxX){ x -= (x2 - maxX); x2 = maxX; if (x < 0) x = 0; } if (y < 0){ y2 -= y; y = 0; if (y2 > maxY) y2 = maxY; } if (y2 > maxY){ y -= (y2 - maxY); y2 = maxY; if (y < 0) y = 0; } jcrop_api.setSelect([ x,y,x2,y2 ]); } }); </script> </head> <body> <img src="http://deepliquid.com/projects/Jcrop/demos/demo_files/sago.jpg" id="cropbox" /> <div id="slider"></div> </body> </html> </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.
