Re: Cedet Semantic does not show overloaded functions in either: semantic-ia-complete-symbol-menu OR autocomplete-text after period

Hi Dixon,

You can use the function:

M-x semantic-ia-show-variants RET

to show all the variants available with the same name.

What happens when you are doing completions is up the the completion UI 
engine.  The core routine `semantic-analyze-possible-completions' takes 
arguments that will allow it to return all the variants if desired.

I don't do too much with my functions `semantic-ia-complete-symbol-menu' 
etc as there are other things like company-mode and autocomplete where 
the author spends much more time one what keypresses should do than I do.

That said, if you think the menu should show the variants, and would 
like to provide a patch for a better version, that is fine with me.  The 
code should be a very simple change if you look at how 'show variants' 
works vs the menu function.  Probably just adding a couple symbols as 
below untested patch.  Doing the same to the completion-tip might be 
nice too.  I'd recommend trying it out for a while and make sure it 
doesn't drive you batty first though.  :)

Eric
