[Mono-osx] Dynamically add User Control (SubView) defined in the Nib

[Tomas Trescak]

Dears

I'm very new to the Cocoa - Objective C programming, but I have more 
than 8 years of c# programming.
My problem is following:

How do I dynamically add a new user control (Cocoa control) to the 
interface.
The control is defined in the NIB (.nix) file.
I could not do this nor in the Interface Designer, nor in the program code.
For the "Groupbox" control I have found a method "AddSubview" which does 
nothing, but I'm just probably not using it right.

Any ideas are greatly appreciated

Have a wonderful day

Tomas
