Message-ID: said:
Does it open an external tcl process;
No.
The ancient version of Ruby/Tk uses interprocess communication
with the Tcl/Tk (wish) process.
does it include the Tcl libraries and run Tk in-process;
Current Ruby/Tk links Tcl and Tk libraries and works on one
process (except native threads created in Tcl/Tk libraries).
So, supported features (widget, option, and so on) depend on
the linked Tcl/Tk linbrary version. And Ruby/Tk can controll
all features of the linked Tcl/Tk libraries by Tk.ip_invoke
or Tk.ip_eval as if the features are introduced after the
latest Ruby/Tk release (including unknown Tcl/Tk extension).
has all the Tcl/Tk code been ported into Ruby/Tk so that Tcl
isn't necessary?
No.
Ruby/Tk uses native Tcl/Tk libraries. Therefore, needs both
of Tcl and Tk libraries.
Some features of Tcl/Tk are supported by Tcl/Tk's library
scripts. If need to make the features work, linked Tcl/Tk
libraries must be able to access the library scripts.
Also, does Ruby/Tk support antialiasing? I know the latest versions
of Perl/Tk do. If not, are there any plans to port Perl/Tk's
antialiased font to Ruby/Tk?
Based on 'New Tcl/Tk8.5 features',
-------------------------------------------
anti-aliased font support on X-Windows (already supported on Win/Mac)
-------------------------------------------
(see
http://www.tcl.tk/software/tcltk/8.5.html).
It means that Ruby/Tk supports antialiased font if your Ruby/Tk
works with libraries of Tcl/Tk8.5.
Please check your Tcl/Tk version by Tk::TK_PATCHLEVEL.
Ruby/Tk on latest CVS is tested with the latest version of Tcl/Tk
(develop:8.5a1 and stable:8.4.6).
