How to get a menu checkbutton to call a function in Python + Tkinter? -

-

so, i'm in personal project (just try myself) python + tkinter. encrypter, means gets piece of text , encrypts using famous cyphers (like numerical cypher, caesar's cypher, , others).
now, wanted give user option save text encrypted, , encrypted text generated program. that, created 2 checkbutton on program's menu: 1 "save text" , other "save encrypted text". question is, tried attach function it's command option, so, guess should run function when option clicked. isn't happening.
i'll explain funcitions shouls before passing code.
should prompt question, asking user if he/she wants create text file text , encrypted text (this isn't database, it's user able read later text's he/she encrypted , encrypted version, if he/she wants to). so, code:

encryptermenu = menu(menubar, tearoff=0) encryptermenu.add_checkbutton(label="save text", variable=v, command=savetext) encryptermenu.add_checkbutton(label="save encrypted text", variable=w, command=saveencryptedtext) menubar.add_cascade(label="encrypter", menu=encryptermenu)

the checkbutton options, , functions:

def savetext():     sdtst = messagebox.askyesno(title="save text", message="a .txt file created @ same directory program save text decided encrypt. ok?")  def saveencryptedtext():     sdtset = messagebox.askyesno(title="save encrypted text", message="a .txt file created @ same directory program save encrypted text generated program. ok?")

should checkbutton run function on-click or making confusion? anyway, hope me.

to answer specific question, yes, function called when click on checkbutton.

you should calling add_command rather add_checkbutton on menu. using checkbutton call function menu highly unusual , confuse users.

c++ - Function signature as a function template parameter -

-
i'd use function signature template argument. works great classes, when try same trick function templates, msvc throws error: error c2768: 'func' : illegal use of explicit template arguments here's code: template <typename signature> void func(); template <typename r, typename a1> void func<r(a1)>(); what should make work? you cannot partially specialize function template, not supported language. can create partially specialized class template static member function, , possibly trampoline function instantiate class template , invoke static function. something this: namespace detail { template<typename signature> struct helper; template<typename r, typename a1> struct helper<r(a1)> { static void call() { // stuff r , a1... } }; } template<typename signature> void func() { detail::helper<signature>::call(); }

algorithm - What are some ways to combine a number of (potentially incompatible) sorted sub-sets of a total set into a (partial) ordering of the total set? -

i have sorting problem i'm pretty sure doesn't have canonical "answer" - has number of different approaches, each pros/cons. i'm interested in hearing different approaches. suppose bunch of people {p_i | i=1,...,m} ranking favorite ice cream flavors. in total there n different flavors, single person p_i ranks n_i << n flavors or familiar with. i'm interested in combining these sub-rankings plausible overall ranking of n flavors. for concrete situation: m , n both 1000 (by coincidence), , each n_i 20 . can assume there's enough overlap in flavors people rank such no flavor "isolated". again, i'm interested in hearing different ways approach this, if there isn't single clear answer. thanks! one way approach problem construct directed cyclic graph representing of constraints on ordering of elements. nodes in graph represent different elements compared , have edge first node second node if had ranked first e...

there's function on page want call after loads. not own page, can't insert html it. can please provide specific examples how chrome extension or greasemonkey?
