I have been working on a bus tracker app for Philadelphia, and I wrote it as a web app to ease porting to iOS/Android/etc. I figured I could make it into a native app using a QtWebView, but when I try to build it Javascript tells me that there is no navigator.geolocation object. According to the docs there should be, but I can't find a simple example of how to make it work anywhere on the web (I'm rather new to QT, so the one app that I found I couldn't figure out which parts were the functional bits I needed).

Could anyone give me some advice here?

Theoretically using
Code:
bool WebView::evaluateJavaScript ( string scriptSource )
you can pass QML variables to the webview element, so you can use a QML PositionSource element to find the location and pass it as a variable to the web view

Ok, so I would need to just pass in JavaScript that redefines navigator.geolocation.getCurrentPosition to call with the current lat/lon. How do I set up a PositionSource element? Is there a good source for tutorials on things like this? (Again, I'm rather new to QT.)

I don't know of a good tutorial but you can start here

http://doc.qt.nokia.com/qtmobility/q...ionsource.html

and check oobProfile source for a working example
