我正在与网格树拖ñ滴。我能够通过从网格中拖动它来将新节点添加到树的根，但是我不知道如何将子节点添加到节点，我将它徘徊在？我花了2天的DIS但没有luck.below是我的代码：extjs 4网格树拖拽
Ext.define('Overdrive.view.ui.MyViewport', {
extend: 'Ext.container.Viewport',
initComponent: function() {
var me = this;
me.items = [{
xtype: 'panel',
height: 600,
layout: {
align: 'stretch',
type: 'hbox'
},
title: 'PARENT',
items: [{
xtype: 'treepanel',
border: '',
id: 'treepanel',
collapseDirection: 'left',
collapsible: true,
title: 'Items',
titleCollapse: true,
store: 'Test',
flex: 1,
viewConfig: {
listeners: {
render: function (tree) {
var dropTarget = new Ext.dd.DropTarget(tree.el, {
ddGroup: 'gridtotree',
copy: false,
notifyDrop: function (dragSource, event, data) {
var idFrom = data.records[0].data.name;
var node = Ext.getCmp('treepanel').getRootNode(); //working
node.appendChild({
'text': idFrom,
'children': []
});
}
});
}
}
}
}, {
xtype: 'panel',
height: 596,
flex: 3,
items: [{
xtype: 'panel',
height: 285,
layout: {
type: 'anchor'
}
}, {
xtype: 'gridpanel',
id: 'itemtypegrid',
title: 'Item Type',
store: 'GridTest',
enableDragDrop: true,
ddText: 'Shift Row',
columns: [{
xtype: 'gridcolumn',

text: 'Name'
}],
viewConfig: {
plugins: [
Ext.create('Ext.grid.plugin.DragDrop', {
ddGroup: 'gridtotree',

}]
}];
me.callParent(arguments);
}
