(31) tcl/tk tree display on win32 systems (Windows 95, 98, NT, 2000)
a. I went to http://dev.scriptics.com/software/tcltk/download82.html and downloaded the
install file tcl823.exe.
Clicking on this, I let it unpack in the default directory, which was c:\Program Files\Tcl
In c:\Program Files\Tcl\bin there is a program called: wish82.exe. I added c:\Program Files\Tcl\bin
to my PATH.
This is the program that I use to display trees from SWI Prolog.
NB: If you install one of the more recent versions of tcl/tk, they should still work. But to use them
with our wish_tree predicate, you will have to (i) find out the name of your wish executable (the
equivalent of our wish82.exe, and then (ii) replace occurrences of wish82.exe in wish_tree with
that name.
b. I installed swiprolog, and put the icon for c:\Program Files\pl\bin\plwin.exe on my desktop.
c. Clicking on this icon, I set the properties of this program so that it would run in my prolog directory,
which is c:\pl
d. Then I downloaded all the win32 SWI-Prolog files from the webpage into my prolog directory, c:\pl
e. Then, starting pl from the icon on the desktop, I can execute
?- [wish_tree.pl].
?- wish_tree(a/[b/[],c/[]]).
This draws a nice tree in a wish window.
f. TODO: Really, we should provide a proper tk interface for SWI Prolog, or else an implementation of
the tree display in XPCE. If anyone wants to do this, and succeeds, please share the fruits of your
labor!
