    Composition

32. HTML Composition JS Window WebView Creation Sequence: <Window>! <WebView />!

    </Window>!

33. Interaction HTML JS App-to-Chart Communication: App Ti.App.fireEvent(…);! WebView with Events

34. Interaction HTML App WebView Chart-to-App Communication: Ti.App.fireEvent(…);! JS with Events

35. Interaction HTML JS WebView App-to-Chart Communication: App webView.evalJS(…);! without Events

36. Interaction HTML App WebView Chart-to-App Communication: // NOPE! JS without

    Events

37. Interaction // Event handler in HTML/JS.! function render(e) {…};! Ti.App.addEventListener(‘renderChart’,

    render);! (In HTML/JS) // Send data to the chart.! Ti.App.fireEvent(‘renderChart’, {…});! (In App) App-to-Chart Communication: with Events

38. Interaction // Event handler in app.! function chartCB(e) {…};! Ti.App.addEventListener(‘chartTapped’,

    chartCB);! (In App) // Send data to the app.! Ti.App.fireEvent(‘chartTapped’, {…});! (In HTML/JS) with Events Chart-to-App Communication:

39. Interaction // No event handler, just the method to render

    data.! function render(chartInfo) {…};! (In HTML/JS) // Send data to the chart.! var data = JSON.stringify(chartInfo);! webView.evalJS(‘render(‘ + data + ‘)’);! (In App) App-to-Chart Communication: without Events
