question about GDB mode in emacs

[andylcx]

Hi all:
   I am using the gdb-mode in emacs and feel it is terrific nice
compared with visual studio from microsoft. But I have one question
about the gud-ui frame. To be more specificly, the problem is the
locals of xxx window(name of the debugged program). When my debugger is
in the main program, this mini-window can display all of the local
variables of the main program correctly. However, if I step into other
function or other class, it cannot display the local variables of that
function or class(the window displays "no locals"). Is there anyway to
ask this window dynamicly display all of the local variables(if it can
only display the local variables of main program, it will be bad)?
Thanks a lot for your response.
