diff Modules/_tkinter.c @ 6343:689de613ea1c legacy-trunk
Add an optional hack for threads in Tkinter.
This one works! However it requires using a modified version of
tclNotify.c (provided), which requires access to the Tcl source
to compile it. In order to enable this hack, add the following
to the Setup line for _tkinter:
tclNotify.c -DHAVE_PYTCL_WAITUNTILEVENT -I$(TCL)/generic
where TCL points to the source tree of Tcl 8.0. Other versions
of Tcl are not supported.
The tclNotify.c file is copyrighted by Sun Microsystems; the
licensing terms are in the file license.terms. According to this
file, no further permission to distribute this is required,
provided the file license.terms is included. Hence, I am checking
that in, too.
