Class commands in Tk correspond to class constructors in Tkinter.
button .fred =====> fred = Button()
The master of an object is implicit in the new name given to it at
creation time. In Tkinter, masters are specified explicitly.
button .panel.fred =====> fred = Button(panel)
The configuration options in Tk are given in lists of hyphened tags
followed by values. In Tkinter, options are specified as
keyword-arguments in the instance constructor, and keyword-args for
configure calls or as instance indices, in dictionary style, for
established instances. See section 16.1.6 on
setting options.
button .fred -fg red =====> fred = Button(panel, fg = "red")
.fred configure -fg red =====> fred["fg"] = red
OR ==> fred.config(fg = "red")
In Tk, to perform an action on a widget, use the widget name as a
command, and follow it with an action name, possibly with arguments
(options). In Tkinter, you call methods on the class instance to
invoke actions on the widget. The actions (methods) that a given
widget can perform are listed in the Tkinter.py module.
.fred invoke =====> fred.invoke()
To give a widget to the packer (geometry manager), you call pack with
optional arguments. In Tkinter, the Pack class holds all this
functionality, and the various forms of the pack command are
implemented as methods. All widgets in Tkinter are
subclassed from the Packer, and so inherit all the packing
methods. See the Tix module documentation for additional
information on the Form geometry manager.
pack .fred -side left =====> fred.pack(side = "left")
