The Web Browser Engine exports a global pointer called _webViewInstancePtr. It performs a similar function to the GfWindow object's setInstancePtr() function for WebKit operations, where the GfWindow object is not known. In general, this pointer must be set whenever the launcher has created multiple WebView instances and the launcher's event handler makes calls into WebKit using the WebView API. This is so that the dispatch and timer pulses received back from WebKit always contain correct instance information. |
