Version: unspecified (using Devel) OS: MS Windows Binding delegates to Qyoto slots often failed for me. Recently recompiled for .NET 4 and the Managed Debugging Assistant pointed me to the following problems: - The Extern functions in QObjectExtras.cs don't have a CallingConvention specified, defaults to the wrong __stdcall on Windows. - In C# code, the delegate is 'set' with ConnectDelegate, then stored as Function pointer in C. When it is invoked, InvokeDelegate will create a new delegate from that function pointer. .NET requires a fully defined delegate type instead of the general Delegate for this. The first issue is easily solved, the second I solved for me by changing delegateinvocation.h to pass the GCHandle instead of the function pointer: int qt_metacall(QMetaObject::Call call, int id, void **a) { id = QObject::qt_metacall(call, id, a); if (id < 0) return id; if (call == QMetaObject::InvokeMetaMethod) { if (id == 0) { smokeStackFromQtStack(_stack, a + 1, 0, _items, _mocargs); next(); (*InvokeDelegate)(_handle, _sp); } --id; } return id; } And SmokeInvocation.cs to accept it and find the delegate linked to it: static public void InvokeDelegate(IntPtr _d, IntPtr stack) { Delegate d = (Delegate)GCHandle.FromIntPtr(_d).Target; unsafe { Reproducible: Sometimes
Can you attach a patch (produced with 'git diff' for example)? I'd apply this, if it looks good.
