Ext.onReady(function(){
var tree = new Ext.tree.TreePanel({
renderTo:'tree-div',
title: 'My Task List',
height: 300,
width: 400,
useArrows:true,
autoScroll:true,
animate:true,
enableDD:true,
containerScroll: true,
rootVisible: false,
frame: true,
root: {
nodeType: 'async'
},
在上面的代碼中,useArrows:true
的含義是什麼?是用箭頭顯示樹結構的屬性(內置)?'useArrows:true'的意義是什麼?
