It would be nice if there was a simple way to return
data to a tcl script without having to do something
like this:

char result[256];
sprintf(result, "%f", h->pos.x);
Tcl_SetResult( Togl_Interp(togl),
result,
TCL_VOLATILE);
return TCL_OK;

I'd rather see something like:

Togl_result_printf("%f", h->pos.x);
return TCL_OK;

I used to use mktclapp to add GUIs to my c/c++
programs, and it had functionality similar to what I am
describing. It was *extremely* helpful when coding to
have such a simple way to return data.

    What you want is Tcl_SetObjResult(interp,
    Tcl_NewDoubleObj(h->pos.x))

    Hi Dan,

    Give this a shot:

    Tcl_SetVar2Ex(interp, "dummy", NULL,
    Tcl_NewDoubleObj(h->pos.x), 0);
