When are toolkit file dialogs used?

[Richard Stallman]

In man/files.texi I am rewriting

  When Emacs is built with a suitable GUI toolkit, it pops up the
standard File Selection dialog of that toolkit instead of prompting for
the file name in the minibuffer.  On Unix and GNU/Linux platforms, Emacs
does that when built with LessTif and Motif toolkits; on MS-Windows, the
GUI version does that by default.

as follows:

  When Emacs is built with a suitable GUI toolkit, commands invoked
with the mouse use standard File Selection dialog of that toolkit
instead of prompting for the file name in the minibuffer.  On Unix and
GNU/Linux platforms, Emacs does that when built with GTK, LessTif, and
Motif toolkits; on MS-Windows, the GUI version does that by default.


However, is that correct nowadays?  Or is more changed needed?
