31. Application WebView HTML / CSS / JS JS Chart Library 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

51. WebView Event Quiz When is the “load” event fired? A.  After the WebView contents have loaded B.  After the WebView contents have rendered C.  Never
52. WebView Event Quiz When is the “load” event fired? A.  After the WebView contents have loaded B.  After the WebView contents have rendered C.  Never
53. WebView Event Quiz When do the contents start loading? A.  After the Window has been laid out B.  After the WebView has been laid out C.  Before the WebView has been laid out
54. WebView Event Quiz When do the contents start loading? A.  After the Window has been laid out B.  After the WebView has been laid out C.  Before the WebView has been laid out * “postlayout” event
55. WebView Event Quiz When is the WebView laid out? A.  Before the Window “postlayout” event B.  After the WebView “focus” event C.  Whenever the OS feels like it
56. WebView Event Quiz When is the WebView laid out? A.  Before the Window “postlayout” event B.  After the WebView “focus” event C.  Whenever the OS feels like it
57. WebView Event Quiz Order of events: 1.  “postlayout” 2.  “beforeload” 3.  “load” (App lays out Views As-Needed)
58. Performance Views are being laid out …
59. Performance “postlayout” and “load” “postlayout” and “load”
60. Performance “postlayout” and “load”
61. Performance “postlayout” and “load” “postlayout” and “load” “postlayout” and “load”
62. Performance WebView loads are throttled … NO big spikes! NO crashes!
63. Reasonable Expectations •  Kickass Charts •  Performance •  Don’t Be So Lazy Enterprise Charting! ✔ ✔ ✔
64. SUMMARY! Amazing charts!! Happy clients!! Don’t FEAR the HYBRID! Great performance!!
