Freeze is a tool to create stand-alone applications. When freezing Tkinter
applications, the applications will not be truly stand-alone, as the application
will still need the Tcl and Tk libraries.
One solution is to ship the application with the Tcl and Tk libraries, and point
to them at run-time using the TCL_LIBRARY and TK_LIBRARY
environment variables.
To get truly stand-alone applications, the Tcl scripts that form the library
have to be integrated into the application as well. One tool supporting that is
SAM (stand-alone modules), which is part of the Tix distribution
(http://tix.sourceforge.net/).
Build Tix with SAM enabled, perform the appropriate call to
Tclsam_init(), etc. inside Python’s
Modules/tkappinit.c, and link with libtclsam and libtksam (you
might include the Tix libraries as well).
On platforms other than Windows, yes, and you don’t even
need threads! But you’ll have to restructure your I/O
code a bit. Tk has the equivalent of Xt’s XtAddInput() call, which allows you
to register a callback function which will be called from the Tk mainloop when
I/O is possible on a file descriptor. See File Handlers.
An often-heard complaint is that event handlers bound to events with the
bind() method don’t get handled even when the appropriate key is pressed.
The most common cause is that the widget to which the binding applies doesn’t
have “keyboard focus”. Check out the Tk documentation for the focus command.
Usually a widget is given the keyboard focus by clicking in it (but not for
labels; see the takefocus option).
