tkinter OptionMenu conform to standard widget options, #101284
Description
The current implementation of tkinter.OptionMenu creates the widget in a manner different from all other tkinter widgets.
cpython/Lib/tkinter/__init__.py
Line 4020 in 38cc24f
Here is a proposed method to deal with this widget.
def __init__(self, master=None, cnf={}, **kw):
"""Construct an optionmenu widget with the parent MASTER,
Supports kwarg configurations from MenuButton.
"""
values = kw.pop('values', [])
value = kw.pop('value', None)
kw['borderwidth'] = kw.get('borderwidth', 2)
variable = kw['textvariable'] = kw.pop('variable', StringVar())
variable.set(value)
kw['indicatoron'] = kw.get('indicatoron', 1)
kw['relief'] = kw.get('relief', RAISED)
kw['anchor'] = kw.get('anchor', "c")
kw['highlightthickness'] = kw.get('highlightthickness', 2)
callback = kw.pop('command', None)
Widget.__init__(self, master, "menubutton", cnf, kw)
self.widgetName = 'tk_optionMenu'
menu = self.__menu = Menu(self, name="menu", tearoff=0)
self.menuname = menu._w
menu.add_command(label=value,
command=_setit(variable, value, callback))
for v in values:
menu.add_command(label=v,
command=_setit(variable, v, callback))
self["menu"] = menuI have replace the kw dict with dict.pop and dict.get methods to allow users to override the standard values while keeping the style the same.
I have also conformed the init args to be the same as standard widgets using master, cnf and kw with default values.
This should be a drop in replacement to the OptionMenu.init method.
(FYI i dont know how to do PRs yet and the doc string probably needs editing.)

The originally proposed patch is not "a drop-in replacement", it breaks signature.
#151959 adds support of all standard options without breaking.
