Each instance has its own associated Tcl interpreter. Inherits from Misc and Wm.\n\nTo create a Tcl interpreter without initializing the Tk subsystem, use the Tcl factory function instead.\n\nThe Tk class is typically instantiated using all default values. However, the following keyword arguments are currently recognized\n\nscreenName When given (as a string), sets the DISPLAY environment variable. (X11 only) baseName Name of the profile file. By default, baseName is derived from the program name (sys.argv[0]). className Name of the widget class. Used as a profile file and also as the name with which Tcl is invoked (argv0 in interp). useTk If True, initialize the Tk subsystem. The tkinter.Tcl() function sets this to False. sync If True, execute all X server commands synchronously, so that errors are reported immediately. Can be used for debugging. (X11 only) use Specifies the id of the window in which to embed the application, instead of it being created as an independent toplevel window. id must be specified in the same way as the value for the -use option for toplevel widgets (that is, it has a form like that returned by ~Misc.winfo_id).\n\nTk reads and interprets profile files, named .{className}.tcl and .{baseName}.tcl, into the Tcl interpreter and calls exec on the contents of .{className}.py and .{baseName}.py. The path for the profile files is the HOME environment variable or, if that isn't defined, then os.curdir.\n\nA !Toplevel widget is a top-level window, similar to a Frame except that its X parent is the root window of a screen rather than its logical parent. Its primary purpose is to serve as a container for dialog boxes and other collections of widgets; its only visible features are its background and an optional 3-D border. Notable options include menu, which installs a Menu as the window's menubar. Inherits from BaseWidget and Wm, so a toplevel is managed by the window manager. Refer to the Tk toplevel manual page for the full list of options.\n\nAttribution: Adapted from Python Documentation under PSF-2.0.
