extjs treenode position

is there any开发者_开发知识库way to find the xy position of a treenode

Assuming that you are referring to a TreeNodeUI element, all you need to do is get the underlying HTML element using Ext.get, then call the getXY method. It should be something like this:

var extElem = Ext.get(treeNode.getEl()); //the Ext.get may not be necessary in this case.
var xy = extElem.getXY(); //returns [x, y]
