Set checkboxes as already checked

[GoogleCodeExporter]

If you set the input checkboxes as already checked on page load this is 
not replicated by the code.

Here is a possible patch for this issue.

If you add the following before the return $tree line:

$tree.find("li")
     .children(":checkbox")
     .each(function() {
         var $c = jQuery(this);
         var $checked = $c.get(0).checked;
         var $allChildren = $c.siblings('ul').children().children(':checkbox');
         var $checkedChildren = $allChildren.filter(function() { return
jQuery(this).get(0).checked });
         var $sibs = $c.siblings("div.checkbox");

         if ($checked && $checkedChildren.length == $allChildren.length) {
             $sibs.addClass("checked");
         } else if (!$checked && $allChildren.length > 0 && $checkedChildren.length >
0) {
             $sibs.addClass("half_checked");
         }
     });

initial reset of checkbox state should be also changed from .attr("checked", "")
[line 88] to .attr("checked", function() { return this.checked } )

Is this the same as bug 4?

It seems that this is the same as #4

On another note, here is a better block of code for my previous post.  It is 
much faster.

var recursiveCheck = function(branch) {
    var thisState = null;
    branch = jQuery(branch);
    branch.children("ul").children().each(function() {
        var childState = recursiveCheck(this);
        if (thisState == null) {
            thisState = childState;
        } else if (thisState != childState) {
            thisState = "half_checked";
        }
    });
    if (thisState == null) {
        thisState = (branch.children()[2].checked) ? "checked" : "";
    }
    jQuery(branch.children()[1]).addClass(thisState);
    return thisState;
}

$tree.children("li").each(function() {
    recursiveCheck(this);
});
