Hi Lee, There are two ways we can bind C with JS. First implementation is to create a runtime object which doesn't have a data type (JavaScriptCore/bindings/testbindings.cpp). This means you can create an object like "foo" with any number of properties and methods. and you can directly access
foo.fooBar(); or foo.var However you cannot create more than one object like: var a = new Complex(a,b); a.real a.img For this you need to understand the math_object.cpp. Regards, Shakti On Thu, Apr 3, 2008 at 3:31 PM, Lee Ka Yuk <[EMAIL PROTECTED]> wrote: > Hi all, > > I'm using the WebKit project for webpage rendering on Qtopia. > I would like to add some Javascript objects that can be accessed in the > webpage and implemented with C/C++. > > I studied JavaScriptCore/kjs/math_object.* and successfully added a object > in JavaScriptCore/kjs. > But I doubt if this is the "correct" way of doing so. > And this method is not at all useful if I would like to access the SAME > C/C++ object in the main application. > Say I added a foo object with member var, I would like to modify and > retrieve foo.var in BOTH QtLauncher and Javascript (synchronization put > aside first). > > There are some test apps in JavaScriptCore/bindings/ that seems to do what > I wanted. > But I'm again confused what are the different between C-binding in > JavaScriptCore/bindings/c and those code in JavaScriptCore/bindings/. > JavaScriptCore/bindings/NP_jsobject.h seems to be yet another API. > > Then I noticed WebCore also provide some binding in WebCore/bindings/js. > How is it different from that in JavaScriptCore/bindings? > > Which binding should I use that would fit the architecture best? > Must I understand JavaScriptCore/API in order to add the object?
