I have a GridPanel with a Remove button. How can my deleteHandler figure out which rows have been selected?


Ext.onReady(function(){

Ext.QuickTips.init();

var xg = Ext.grid;

// shared reader
var reader = new Ext.data.ArrayReader({}, [
{name: 'company'},
{name: 'price', type: 'float'},
{name: 'change', type: 'float'},
{name: 'pctChange', type: 'float'},
{name: 'lastChange', type: 'date', dateFormat: 'n/j h:ia'},
{name: 'industry'},
{name: 'desc'}
]);


////////////////////////////////////////////////////////////////////////////////////////
// Grid 4
////////////////////////////////////////////////////////////////////////////////////////
var sm2 = new xg.CheckboxSelectionModel({
listeners: {
// On selection change, set enabled state of the removeButton
// which was placed into the GridPanel using the ref config
selectionchange: function(sm) {
if (sm.getCount()) {
grid4.removeButton.enable();
} else {
grid4.removeButton.disable();
}
}
}
});

function addHandler(scope, options)
{
alert('a here');
}

function deleteHandler(scope, options)
{
alert('d here');
}

var grid4 = new xg.GridPanel({
id:'button-grid',
store: new Ext.data.Store({
reader: reader,
data: xg.dummyData
}),
cm: new xg.ColumnModel([
sm2,
{id:'company',header: "Company", width: 40, sortable: true, dataIndex: 'company'},
{header: "Price", width: 20, sortable: true, renderer: Ext.util.Format.usMoney, dataIndex: 'price'},
