Hello, Having read through the following document "Using JavaScript From Objective-C":
http://developer.apple.com/documentation/AppleApplications/Conceptual/SafariJSProgTopics/Tasks/ObjCFromJavaScript.html#//apple_ref/doc/uid/30001215-BBCBFJCD It seems that the method: WebView::windowScriptObject would be useful to achieve what I wish to do (add a custom JavaScript object). However looking at the source code, it is not implemented on windows: http://trac.webkit.org/browser/trunk/WebKit/win/WebView.cpp#L2709 On Sun, May 17, 2009 at 6:30 PM, Darin Adler <da...@apple.com> wrote: > On May 15, 2009, at 7:35 AM, Jack Wootton wrote: > >> 4.
