ZoomToFitWidthOnLoad in Stagewebview

Hi, I'd like to zoom a StageWebView's HTML content to fit it's width on load to avoid horizontal scrolling. I tried to dispatch an "gesture_zoom" event on the webview but that did not work. I have seen this feature in the QNXStageWebView class from the Blackberry Tablet SDK.

Does annoyone know how to achieve this ? Any help would be highly appreciated

Cheers!
