// PopControl: 		the base of pop up control(eg:a calendar on it)
// Author: 		Lucas zheng
// Date:		2004-6-9
// Param: 		dataStr=the html code of what you want to show
// Using:
//      first.  new a popControl object,use obj.show(popCtrl,textCtrl,valueCtrl,distance) to show the control
//		  popCtrl=the object to snap with;
//                textCtrl=the object to set the return text;
//                valueCtrl=the object to set the return value;
//                distance=the object to move left or right a distance;
//	second. use obj.setReturn() / obj.hide() / obj.popControlKeyDown(event,index) / document.onclick() to hide the control
//	third.  you can add event at beforeShow/afterShow/beforeHide/afterHide/beforeReture()/afterReturn()
//                like this: obj.beforeShow="alert('before show')";
//	fourth. use obj.setReturn(text,val) to get you return and hide control
//                i.e.: var popCtrl=new popControl("<table border=1><tr><td onClick='hideControls();'>asdf,fdsa</td></tr></table>", "left");
