I don't think you are right about the code thing... But anyway, the code of this guy is a mess and mitchel already answered how it should be done. So forget about the code of the guy for a second, cause it is really simple to archive this.
Here's a working snipped how you can do this:
Ext.define('Ext.ux.DemoWin', {
extend: 'Ext.window.Window',
alias: 'widget.demowin',
width: 200,
height: 200,
title: 'demo',
initComponent: function() {
this.callParent(arguments);
},
loadRecord: function(rec) {
// simplified - just update the html. May be replaced with a dataview
this.update(rec.data.name + ' - ' + rec.data.email);
}
});
Ext.create('Ext.data.Store', {
storeId:'simpsonsStore',
fields:['name', 'email', 'phone'],
data:{'items':[
{ 'name': 'Lisa', "email":"[email protected]", "phone":"555-111-1224" },
{ 'name': 'Bart', "email":"[email protected]", "phone":"555-222-1234" },
{ 'name': 'Homer', "email":"[email protected]", "phone":"555-222-1244" },
{ 'name': 'Marge', "email":"[email protected]", "phone":"555-222-1254" }
]},
proxy: {
type: 'memory',
reader: {
type: 'json',
root: 'items'
}
}
});
Ext.create('Ext.grid.Panel', {
title: 'Simpsons',
store: Ext.data.StoreManager.lookup('simpsonsStore'),
columns: [
{ text: 'Name', dataIndex: 'name' },
{ text: 'Email', dataIndex: 'email', flex: 1 },
{ text: 'Phone', dataIndex: 'phone' }
],
height: 200,
width: 400,
renderTo: Ext.getBody(),
listeners: {
// the registration should be done with the control() method of the responsible controller
itemclick: function(grid,record) {
var win = Ext.widget('demowin').show().loadRecord(record);
}
}
});
And here's a JSFiddle
Edit which applies to Ext.ux.desktop.Module
createWindow : function(){
var desktop = this.app.getDesktop();
var win = desktop.getWindow('grid-win');
if(!win){
win = desktop.createWindow({
// ...
loadRecord: function(rec) {
this.update(rec.data.name + ' - ' + rec.data.email);
}
//....
