    <p>I am trying to use Jcrop for my application, though I have run into a bug with it. I went to the demo page, and the bug exists there too. Here is how to create it.</p> <p>Go to this demo page <a href="http://deepliquid.com/projects/Jcrop/demos.php?demo=advanced" rel="nofollow">http://deepliquid.com/projects/Jcrop/demos.php?demo=advanced</a></p> <p>Make sure the following options are checked "Selection can be moved"<br> "Resizable selection" "Aspect ratio" "minSize/maxSize setting"</p> <p>Create a selected area, drag it to the upper left corner, grab the lower right corner of the selection(as if you were going to resize it) and drag it to the upper left corner of the image.</p> <p>Once you pass the upper left corner of the image the select area collapses down to a 0x0 pixel selection.</p> <p>This bug only happens when an aspect ratio is set. Otherwise it works fine.</p> <p>I'm wondering if anyone has any experience hacking around with this plugin to where they might be able to fix this bug. I've been going through it all day and haven't been able to figure it out yet.</p> <p>--Edit-- After spending a few more hours with it I was able to get the bug mostly fixed. I changed the following code.</p> <pre><code> // Magic %-) if(xx &gt;= x1) { // right side &lt;-- Changed &gt; to &gt;= if(xx - x1 &lt; min_x) { xx = x1 + min_x; } else if (xx - x1 &gt; max_x) { xx = x1 + max_x; } if(yy &gt; y1) { yy = y1 + (xx - x1)/aspect; } else { yy = y1 - (xx - x1)/aspect; } } else if (xx &lt;= x1) { // left side &lt;-- Changed &lt; to &lt;= if(x1 - xx &lt; min_x) { xx = x1 - min_x } else if (x1 - xx &gt; max_x) { xx = x1 - max_x; } if(yy &gt; y1) { yy = y1 + (x1 - xx)/aspect; } else { yy = y1 - (x1 - xx)/aspect; } } </code></pre> <p>This stopped it from collapsing, its still acts a little buggy though.</p> <p>--End Edit--</p>

    1. COI am the author of Jcrop. I am aware of this issue. As you have found, it's quite vexing. I may need some community help to resolve it. I will look into the code above and see if those changes can be applied. I will also try to take another crack at it. Feel free to contact me through my website. Thanks for posting!

    2. COActually it looks the fix is only buggy in 0.9.8, in 0.9.9 it actually seems to work pretty well. I haven't checked across browsers yet.

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.
