CEFUserData usage

[Meghavi]

Hi,

I am not able to gather much information about CEFUserData and in which scenarios to use it.
Can someone provide a simple usecase for which CEFUserData could be used.

Thanks

UserData allows you to associate an object derived from CefBase with a V8 object. It's life span will be correllated with the V8 object's life span (the V8 object keeps a reference to the UserData object that gets released when the V8 object is GC'ed). The UserData object can be retrieved from the V8 object in native code via GetUserData.

That looks like a cool feature. I haven't noticed it earlier in header files. How should I make the cast
when calling GetUserData(), for it to be safe?

Only your application will assign UserData objects, so you can provide your own base class extending CefBase that provides isX() and toX() methods.

Thanks.
Can this CefUserData be accessed in Javascript?

No, UserData is only available from native code. You can of course define your own JS bindings that access the UserData.

Thanks this feature has proved very useful to us

Hello,

Just like Meghavi, I'm interested in how can I benefit from using CefUserData?

Meghavi, could you please elaborate on how you used the CefUserData?

Thanks
