/* appinit.c -- Tcl and Tk application initialization.    The function Tcl_AppInit() below initializes various Tcl packages.   It is called for each Tcl interpreter created by _tkinter.create().   It needs to be compiled with -DWITH_<package> flags for each package   that you are statically linking with.  You may have to add sections   for packages not yet listed below.    Note that those packages for which Tcl_StaticPackage() is called with   a NULL first argument are known as "static loadable" packages to   Tcl but not actually initialized.  To use these, you have to load   it explicitly, e.g. tkapp.eval("load {} Blt"). */ #include <string.h>#include <tcl.h>#include <tk.h> intTcl_AppInit(Tcl_Interp *interp){	Tk_Window main_window;	const char * _tkinter_skip_tk_init; #ifdef TK_AQUA#ifndef MAX_PATH_LEN#define MAX_PATH_LEN 1024#endif	char tclLibPath[MAX_PATH_LEN], tkLibPath[MAX_PATH_LEN];	Tcl_Obj*	pathPtr;         /* pre- Tcl_Init code copied from tkMacOSXAppInit.c */	Tk_MacOSXOpenBundleResources (interp, "com.tcltk.tcllibrary",       	tclLibPath, MAX_PATH_LEN, 0); 	if (tclLibPath[0] != '\0') {       	Tcl_SetVar(interp, "tcl_library", tclLibPath, TCL_GLOBAL_ONLY);		Tcl_SetVar(interp, "tclDefaultLibrary", tclLibPath, TCL_GLOBAL_ONLY);		Tcl_SetVar(interp, "tcl_pkgPath", tclLibPath, TCL_GLOBAL_ONLY);	}	   	if (tclLibPath[0] != '\0') {		Tcl_SetVar(interp, "tcl_library", tclLibPath, TCL_GLOBAL_ONLY);		Tcl_SetVar(interp, "tclDefaultLibrary", tclLibPath, TCL_GLOBAL_ONLY);		Tcl_SetVar(interp, "tcl_pkgPath", tclLibPath, TCL_GLOBAL_ONLY);	}#endif	if (Tcl_Init (interp) == TCL_ERROR)		return TCL_ERROR; #ifdef TK_AQUA        /* pre- Tk_Init code copied from tkMacOSXAppInit.c */	Tk_MacOSXOpenBundleResources (interp, "com.tcltk.tklibrary",            tkLibPath, MAX_PATH_LEN, 1); 	if (tclLibPath[0] != '\0') {		pathPtr = Tcl_NewStringObj(tclLibPath, -1);	} else {		Tcl_Obj *pathPtr = TclGetLibraryPath();	} 	if (tkLibPath[0] != '\0') {		Tcl_Obj *objPtr; 		Tcl_SetVar(interp, "tk_library", tkLibPath, TCL_GLOBAL_ONLY);		objPtr = Tcl_NewStringObj(tkLibPath, -1);		Tcl_ListObjAppendElement(NULL, pathPtr, objPtr);	} 	TclSetLibraryPath(pathPtr);#endif #ifdef WITH_XXX		// Initialize modules that don't require Tk#endif 	_tkinter_skip_tk_init =	Tcl_GetVar(interp, "_tkinter_skip_tk_init", TCL_GLOBAL_ONLY);	if (_tkinter_skip_tk_init != NULL && strcmp(_tkinter_skip_tk_init, "1")	== 0) {		return TCL_OK;	}	if (Tk_Init(interp) == TCL_ERROR)		return TCL_ERROR; 	main_window = Tk_MainWindow(interp); #ifdef TK_AQUA	TkMacOSXInitAppleEvents(interp);	TkMacOSXInitMenus(interp);#endif    #ifdef WITH_MOREBUTTONS	{		extern Tcl_CmdProc studButtonCmd;		extern Tcl_CmdProc triButtonCmd; 		Tcl_CreateCommand(interp, "studbutton", studButtonCmd,				  (ClientData) main_window, NULL);		Tcl_CreateCommand(interp, "tributton", triButtonCmd,				  (ClientData) main_window, NULL);	}#endif #ifdef WITH_PIL /* 0.2b5 and later -- not yet released as of May 14 */	{		extern void TkImaging_Init(Tcl_Interp *);		TkImaging_Init(interp);		/* XXX TkImaging_Init() doesn't have the right return type */		/*Tcl_StaticPackage(interp, "Imaging", TkImaging_Init, NULL);*/	}#endif #ifdef WITH_PIL_OLD /* 0.2b4 and earlier */	{		extern void TkImaging_Init(void);		/* XXX TkImaging_Init() doesn't have the right prototype */		/*Tcl_StaticPackage(interp, "Imaging", TkImaging_Init, NULL);*/	}#endif #ifdef WITH_TIX        {                extern int Tix_Init(Tcl_Interp *interp);                extern int Tix_SafeInit(Tcl_Interp *interp);                Tcl_StaticPackage(NULL, "Tix", Tix_Init, Tix_SafeInit);        }#endif #ifdef WITH_BLT	{		extern int Blt_Init(Tcl_Interp *);		extern int Blt_SafeInit(Tcl_Interp *);		Tcl_StaticPackage(NULL, "Blt", Blt_Init, Blt_SafeInit);	}#endif #ifdef WITH_TOGL	{		/* XXX I've heard rumors that this doesn't work */		extern int Togl_Init(Tcl_Interp *);		/* XXX Is there no Togl_SafeInit? */		Tcl_StaticPackage(NULL, "Togl", Togl_Init, NULL);	}#endif #ifdef WITH_XXX #endif	return TCL_OK;}
