1 /* appinit.c -- Tcl and Tk application initialization.
2
3 The function Tcl_AppInit() below initializes various Tcl packages.
4 It is called for each Tcl interpreter created by _tkinter.create().
5 It needs to be compiled with -DWITH_<package> flags for each package
6 that you are statically linking with. You may have to add sections
7 for packages not yet listed below.
8
9 Note that those packages for which Tcl_StaticPackage() is called with
10 a NULL first argument are known as "static loadable" packages to
11 Tcl but not actually initialized. To use these, you have to load
12 it explicitly, e.g. tkapp.eval("load {} Blt").
