Question

ExtJs4 中如何让TreePanel的节点可拖动？

Answer 1

//在创建树时配置项enableDD给一个true值就可以了

var tree = new Ext.tree.TreePanel({
width:300,
renderTo: "tree",
root: root,
title:"异步加载数据",
enableDD:true,//允许拖动
...
..

Answer 2

加个插件就可以了
var store = Ext.create('Ext.data.TreeStore', {
root: {
expanded: true,
children: [
{ text: "detention", leaf: true },
{ text: "homework", expanded: true, children: [
{ text: "book report", leaf: true },
{ text: "alegrbra", leaf: true}
] },
{ text: "buy lottery tickets", leaf: true }
]
}
});

Ext.create('Ext.tree.Panel', {
title: 'Simple Tree',
width: 200,
height: 150,
store: store,
viewConfig: {
plugins: {
ptype: 'treeviewdragdrop'
}
},
rootVisible: false,
renderTo: Ext.getBody()
});
