[Mono-list] Problems with delegates (Qt#)
Mon, 30 Dec 2002 17:56:55 -0600
Qt# is having major problems involving delegates. Essentially, we are creating
delegates for C# instances/methods (since a delegate for an instance
encapsulates both the instance and the method), and we are passing the
delegate to unmanaged code. The unmanaged code is supposed to invoke the
delegate at the appropriate time.
Under Mono, delegates with no parameters (e.g. void quit() ) work, but
delegates that take an int, for example (e.g. void display(int) ), are never
The same problems occurs when using mint or mono, and it does not matter
whether the code is compiled with mcs or csc. Interestingly, the same code
does work correctly under Portable.NET.
I really do not know what to do at this point. I have spent hours and hours
trying to figure out why this isn't working. It's seems as though the runtime
is not allowed the unmanaged code to invoke the managed code.
