Bug 133680 – [GTK] WebKitWebView::create should receive information about the navigation action

• Component: WebKitGTK
• Status: RESOLVED FIXED

[Carlos Garcia Campos]

In order to properly implement a popup blocker, the signal should provide information about the navigation action like the navigation type, the request, mouse button and key modifiers and whether it was triggered by a user gesture, at least.

This breaks the API, as we commented in the mailing list. I hope only ephy uses this API, so it will not cause major problems for most of the users that will only have to recompile when we bump the binary version.

Thanks for the patch. If this patch contains new public API please make sure it follows the guidelines for new WebKit2 GTK+ API. See http://trac.webkit.org/wiki/WebKitGTK/AddingNewWebKit2API

Seems okay, though I have a few  nits. I think, if possible, it'd be better to pass WebHitTestResult& everywhere instead of the internal data structure. Probably a good idea to fix up the style errors too. :)

Why not use a bool here?

Nit: Probably "action" is a better name.

Is this really the correct marshaller for a OBJECT and an enum value?

Nit: ContextMenuclient -> ContextMenuClient.

Wow. It'd be great to avoid all these copies! Why not just pass a const WebHitTestResult& instead of Data?

Probably should be called action or navigation_action.

I'm using WebHitTestResult::Data because that's what we receive now in API:UIClient methods, WebHitTestResult is the C API wrapper, but we are not using the C API for the UI client anymore. So, instead of allocating a WebHitTestResult I prefer to use the given const reference. It's only a problem for the context menu, until we use a custom client that receives a const WebHitTestResult::Data& too. And the style issues are false positives of std::function

Oops.

No reason, we can use bool as well.

Ok.

Yes, the generic marshaller can be used for any parameters

That's what the previous FIXME is about :-)

Are these false-positives?

Yes, the style checker thinks they are function calls, but they are std::function parameters

std::function<void ()>, std::function<void (bool) and std::function<void (const String&)>

[Carlos Garcia Campos]

Any other objection here?
