Hello Gavin,
I had a look at the .ccg, .hg and .defs and it seems that enough
parameters have been passed in between them. However I am having a hard
time understanding the WebKit-Gtk code. Here is the appropriate section
of it.
webkit_web_inspector_signals[INSPECT_WEB_VIEW] =
g_signal_new("inspect-web-view",
G_TYPE_FROM_CLASS(klass),
(GSignalFlags)G_SIGNAL_RUN_LAST,
0,
webkit_inspect_web_view_request_handled,
NULL,
webkit_marshal_OBJECT__OBJECT,
WEBKIT_TYPE_WEB_VIEW , 1,
WEBKIT_TYPE_WEB_VIEW);
Here is the signal wrapper in webinspector.hg:
_WRAP_SIGNAL(WebView& inspect_web_view(WebView& web_view),
"inspect-web-view", no_default_handler)
Thanks for your time.

Hi Dannick,
These sorts of errors typically mean that there is some disagreement
on the number or types of parameters between the C signal and its C++
wrapper (in this case "inspect_web_view" on WebKitWebInspector), or in
your parameter conversion definitions. Check the definition of this
signal in the actual WebKit-GTK C code, in the .defs files (I assume
that you have regenerated these as needed), and in your .hg and .ccg
files.
Regards,
Gavin Lambert

value-initialization of reference type 'WebKit::WebView&'
Compilation error messages from libsigc++'s many C++ template
functions and template classes can be very difficult to interpret.
The compiler says the error is in slot.h, but don't take that for
granted. It can be somewhere else. To start with, it's interesting
to know what's in webinspector.cc, around line 249.

Sorry I did not get back sooner here is the function from
webinspector.cc at around line 249. It starts at 235.
static WebKitWebView*
WebInspector_signal_inspect_web_view_callback(WebKitWebInspector*
self, WebKitWebView* p0,void* data)
{
using namespace WebKit;
typedef sigc::slot< WebView&,WebView& > SlotType;
// Do not try to call a signal on a disassociated wrapper.
if(Glib::ObjectBase::_get_current_wrapper((GObject*) self))
{
#ifdef GLIBMM_EXCEPTIONS_ENABLED
try
{
#endif //GLIBMM_EXCEPTIONS_ENABLED
if(sigc::slot_base *const slot =
Glib::SignalProxyNormal::data_to_slot(data))
return ((*static_cast<SlotType*>(slot))(*Glib::wrap(p0)
)).gobj();
#ifdef GLIBMM_EXCEPTIONS_ENABLED
}
catch(...)
{
Glib::exception_handlers_invoke();
}
#endif //GLIBMM_EXCEPTIONS_ENABLED
}
typedef WebKitWebView* RType;
return RType();
}
Here is a link to the github repository I created with the changes I
have made until now.
