本文介绍了一个针对ExtJS中TreeNode组件的简单修改，通过调整ensureVisible方法使其支持回调函数，确保节点可见的同时可以执行额外操作。

The function "ensureVisible" uses "expandPath" which takes a callback to call when the necessary expansions have been completed. "ensureVisible" should also offer the callback.

I'm using:

Ext.override(Ext.tree.TreeNode, {
    ensureVisible : function(callback){
        this.getOwnerTree().expandPath(this.getPath(), false, callback);
    }
});

Can we have that small tweak Please?
