Yes, LLFloaterReg is the current mechanism for creating and displaying new types of floaters (windows).There is a separate mechanism for "notification" style dialogs, in llnotifications*.h/cpp, appropriately enough. Unfortunately, I don't think there is good documentation in the wiki for that yet
You can edit that wiki page or put your information in the discussion tab.
Login to the wiki (upper right) using your SL account information and that will
open up the edit rights. Using external links is subject to broken link errors
so, a direct edit would be best.
I had fumbled through that p
A combination of exploring the source to see how dialogs are currently
implemented & Oz's email got me on the right tracks & I can now spawn a
blank dialog from a new menu entry - incidentally the 2009 page on the
wiki for adding menu entries is still fairly current.
