ext How to add a tabpanel to a window

Of course you can!

undefined, isn't it your new window first, and then the new gridpanel?

You should first update those panels, and only if the panel object exists, you can put it in the item in the window

See here is the gridpanel in the window, I hope it helps you.

A small example that I wrote myself, it works fine.

items:[{

title:'page1',html:'content1',{title:

page2',html:'content2',{title:'page3',html:

content3',closable:true

var win=new

title:'Layout',closable:true, be careful not to write closeable (one more e).

width:600,height:350,border:false,layout:'border',items:[tabs];

Write a method in the window. Like what.

window"Then when you need to open the window, you can use .

Listen to Windows activation events or display events and refresh the FormPanel Store inside

var centerpanel = '', ,clear: function ()title: 'Homepage',autoscroll: true

function trsel(view, record, item, index, e) ,clear: function ()id: "tab" + title:,closable: true,autoscroll: true;;

Sets the display of the current panel.

Functions are called when the menu tree is clicked. You can adjust it yourself, and you can adjust this function when you click the button. However, the Internet said that using iframes is not good, and I also want to see if there are other methods.

var tabpanel1 = '');

var tabpanel2 = '',);

Tabpanel1 as the items item of tabpanel2 will do the trick.

Customize a FormPanel extension class with an array to store data for each FormPanel.

tab references a page and writes grid in the page

Which attribute of which tag you want to change, specifically, is actually explained in the ExtJS API.

There are many solutions! You can set the layout of the popup to be a column or a table. This is set to 3 columns, and then 3 panels can be put into this layout.
