Hello all.

I am new to this and it is not quite easy to find any good docs online except a Squeak image in my hands.

The idea is to allow user to select a fixed size square area in the picture all controlled by my seaside app.

to do so I gonna use Scriptaculous, something like:

html image url: 'test.png';
	id: 'picture';
	width: 800;
	height: 600.

html div id: 'square-selector';
	style: 'border: solid 1px red; width: 432px; height: 432px; position relative; background: transparent';
 	script: (
		html draggable revert: false;
		onEnd: ()

The question is what to put into onEnd: () ???

I want to check drop location of my square-selector inside the picture, adjust it if user went outside the picture
and finally have x and y of top left corner of my square-selector relative to picture stored in ivars (which is trivial).

http://scriptaculous.seasidehosting.st/ examples seems to show that it is possible, but not very clear how to do it.

Please help
