Print Page - TreeGrid: empty folder icon

Hello together,

based on the Lazy loading nodes in TreeGrid example (http://www.jeasyui.com/tutorial/tree/treegrid5.php) i have question about node with an empty children list.

I have modified the data set for this example and add a node with an empty children list on the end

{
   "id":99,
   "name":"D",
   "size":"",
   "date":"02/19/2010",
   "children":[
   ]
}

In the a attached picture (empty_folder1.jpg) you can see a folder icon for D.

If i remove the lazy load functionality by removing the loadFilter data-option from the html file i got this result (empty_folder2.jpg)

The you can see a file icon for D.

How i can defined which icon is display for a node with a children list without members (empty folder).

Override the 'setData' function as below and they will have the same behavior.

Code:

function setData(data){
	var todo = [];
	for(var i=0; i<data.length; i++){
		todo.push(data[i]);
	}
	while(todo.length){
		var node = todo.shift();
		if (node.children && node.children.length){
			node.state = 'closed';
			node.children1 = node.children;
			node.children = undefined;
			todo = todo.concat(node.children1);
		}
	}
}
