C++ question

[Angus Leeming]

I've managed to create a GUI-I ControlCitation class that stores a pointer to 
a ButtonController abstract base class. However, in my xforms specific 
FormViewCitation class, I need to access FormButtonController specific 
functions and must, therefore, resort to dynamic_cast.

Are we allowed to use dynamic_cast in LyX code?
