Store with a polling proxy?

[rclifton]

Hello,

I'm trying to figure out how to build a proxy that polls the server and updates it's Store. I have a regular proxy working that will make a directFn call and update a store once. How can I do this on an interval?

The examples seems to suggest that I should add a listener to the proxy that fires off a poll event. The listener would then grab the model and update the data. Seems plausible, however I just want to make sure that the easiest way to do this. Shouldn't there simply be a proxy type that will make a direct call on an interval and automatically update its Store?

This works, once. I want it to run every X seconds until i tell it to stop.

Ext.define('MyApp.model.SummaryAppModel', {
    extend: 'Ext.data.Model',

    fields: ['name','type','value']
});

Ext.define('MyApp.store.SummaryAppStore', {
    extend: 'Ext.data.Store',
    requires: [
        'MyApp.model.SummaryAppModel'
    ],

    paramsAsHash: false,
    idProperty: 'value',
    storeId: 'SummaryAppStore',
    model: 'MyApp.model.SummaryAppModel',
    groupField: 'type',
    autoLoad: true,
    proxy: {
        type: 'direct',
        directFn: 'RTSStats.getAppStatsDirect'
    }
});

Ext.define('Ext.grid.RTSLeftPanel', {
    extend: 'Ext.grid.Panel',
    alias: 'widget.rtsleftpanel',
    collapsible: false,
    iconCls: 'icon-grid',
    frame: true,
    store: 'SummaryAppStore',
    width: 200,
    resizable: false,
    features: [groupingLeftFeature],
    columns: [{
        text: 'Field',
        flex: 1,
        dataIndex: 'name'
    },{
        text: 'Value',
        flex: 1,
        dataIndex: 'value'
    },{
        text: 'Type',
        flex: 1,
        dataIndex: 'type'
    }]
});

I have used something like this before.

    var buttonAuto = new Ext.Button({
        text: 'Set Interval',
        width: 150,
        renderTo: Ext.getBody(),
        handler: function() {

            var interval = setInterval(function() {
                store.load();
            }, 6000); // refresh every 6 sec
        }
    });

Regards,
Scott.
