As a workaround, I believe you can use
    input_files = root.tk.splitlist(input_files)
which will correctly deal with filenames that contain embedded
characters that have special meaning in Tcl.

Subject: [Tkinter-discuss]  command for dynamic buttons
Message-ID: <24872360.post@talk.nabble.com>


Hello!

I'm making an application with lots of similar buttons. But I can't figure
out how to make the command unique for each button.

I tried to follow the advice in 
http://mail.python.org/pipermail/python-list/2002-July/152242.html this  old
message, but every button still gives the same output.


class Program:
    def __init__(self, ruta):

        bokst = ['?', '?', '?', '?', '?', '?', '?', '?', '?', '?', '?', '?']

        i = 1
        for option in bokst:
            laddaKnapp = lambda index=0, obj=self: obj.tryck(option) 
            knapp = Button(self.nere, text=str(option), command=laddaKnapp)
            knapp.grid(row=1, column=i)
            i = i + 1

    def tryck(self, bokstav):
        self.currText.set(bokstav)
        return


I found how to do it in pygtk in 
http://www.pygtk.org/pygtk2tutorial/examples/clipboard.py this example , but
I've not been able to find a singel example of dynamic buttons in tkinter.

Actually this is not tkinter fault, and pygtk doesn't do magic here either.

For instance, if you translated this to pygtk you would get this:

import gtk

def test(option):
    print option

things = ['a', 'b', 'c', 'd']

win = gtk.Window()
hbox = gtk.HBox()
win.add(hbox)

for indx, option in enumerate(things):
    cmd = lambda event: test(option)
    btn = gtk.Button(option)
    btn.connect('clicked', cmd)
    hbox.pack_start(btn)

win.show_all()
win.connect('destroy', gtk.main_quit)
gtk.main()

Which would always print 'd'. Of course you could change that
"connect" to: btn.connect('clicked', test, option) which you would
proceed to change the test callback to accept an event parameter as
the first argument, but this code is really different.

I didn't look at the email you pointed, but if the suggestion included
there maps to the code you posted then the suggestion is wrong.

import Tkinter

def test(option):
    print option

things = ['a', 'b', 'c', 'd']

root = Tkinter.Tk()

for indx, option in enumerate(things):
    cmd = lambda opt=option: test(opt)
    btn = Tkinter.Button(text=option, command=cmd)
    btn.pack(side='left')

root.mainloop()

The line you are after is "cmd = lambda opt=option: test(opt)". If
instead you do "cmd = lambda: test(option)" (which is equivalent to
what the code you pasted was doing), then when this lambda executes it
will have to grab the value of this name "option" from somewhere,
which will be the last element from the things list.

You don't need indx neither enumerate here (same for the gtk code). I
was going to use grid like you did, but in the end the pasted code
didn't use. I hope this doesn't compromise understanding the problem
described.

You'd have to reverse your text and align it to the right side. Vertically
you'll need newlines after every character, and diagonally you'll need
newlines+spaces.

For Vertical/Diagonal text:
In Tcl/Tk 8.6, the Canavs widget allows text to be rotated 90 degrees
(or other angle).

Now, Python is still using 8.5 I believe. Does anyone know whether if you
compile Python with only Tcl/Tk 8.6 installed, the resulting system will work?

It will work Michael, but before compiling you have to do a minor
tweak on setup.py around like 1540. Just add a '8.6' and '86' on the
list that contains other version numbers so it will also accept
compiling _tkinter with Tcl/Tk 8.6.

If you are using python trunk or the py3k branch to do custom
compilations of _tkinter then update it and the above adjust won't be
necessary anymore.

I suggest to have a look at tkZinc (www.tkzinc.org). It is a Canvas++, so to speak, and I was able to make small maps of the "how to find us" kind. Some street names were shown horizontally, some vertically; I understand you need something similar.

Good luck,

Hmmm, I first thought the OP meant if there is a way to
write right to left or vertically in a Text widget ? If this is the
case I am afraid there is not much hope, I am not absolutely sure,
though.

Subject: [Tkinter-discuss] How do I identify which menu item has bee
 selected?
Message-ID: <25023156.post@talk.nabble.com>


Hi - am using python 2.6 and Tkinter 8.5.

I would like to know how to identify which 'menu item' has been selected
from a cascaded menu.  

The cascaded menu menu items are variable and created on the fly. The idea
is to use a common callback for all menu items, the callback function then
determines which selection was made and runs the appropriate function.

I have tried binding an event to the selection and then trying to get some
sort of info from the event object (event.widget()) but this appears to
return info about the menu class instance and not about it's menu items.  

I've used Java in the past - and if I recall correctly - a menu-item is a
class, in python it seems to be an attribute(list entry) of the menu class -
in which case - how do I interrogate it if I do not know it's index?

Any help is appreciated - it's starting to do my head in!!

Hi Mark,

to build a menu you have:

- create a menubar, which is a Menu object f type menubar:
      mbar = Menu( type='menubar', ... )

- create menus, which also are Menu objects, and adding to the menubar by
using the add_cascade method of the menu  bar:
      menu = menu(master=se,f.mbar, ... )
      mbar.add_cascade( menu )

- populate the menu using the add_command method of the menu:
     menu.add_command( label='Do something', command= do_command_callback )

Now, in Tkinter there is no possibility to specify parameters to pass a
callback, but there are several ways to do it, which you can find following
the links from here:  http://tkinter.unpy.net/wiki/Widgets/Button (section
parameter passing: it refers to button callbacks but the same applies for
menus).

I personally tend to suggest functools.partial, which you should use like
this to have the same callback called with a differemt menu item:

      menu.add_command( label='Do something',
command= functools.partial(do_command_callback, 1  )
       menu.add_command( label='Do something else',
command= functools.partial(do_command_callback, 2  ) )

In case you need more examples of how to use tk widgets with python, have a
look at this suite of the programs that I wrote some time ago (code is a bit
old but still working with latest python versions):

     http://tkinter.unpy.net/wiki/A_tour_of_Tkinter_widgets

P.S : in case you don't know, unlike Java, Python has not a 'default widget
set', that you must use if you are coding in python.
Instead, you can use several among the most popular widget toolkits (Gtk+,
Qt, ... ), even Swing if you use the java version of python (Jython), which
is a bit behind as language version (stable supports Python 2.5, beta
supports Python 2.6).
Tkinter has the advantage of being bundled with python (for the others you
have to dounload and install additional modules) and surely is suitable for
many tasks, especially if for you functionality is more important than look
(although with a bit of effort Tk GUI can also look cool, see for instance
aMSN, a clone of mSN Messanger written using the same toolkit of Tkinter,
but not in Python).

Sorry for the verbosity (feeling bored :-), hope I managed to help in the
process

Ciao

I will try something here, but since you didn't post what you tried it
may not be what you want. I always see my own code indented on email,
but if that is not the case for everyone then it is better to move it
to some paste bin.
Anyway, below is an attempt to do what you want but there is a problem
with it. If you can't guarantee that new entries are added to the end,
then the code needs to be adapted.

import Tkinter

root = Tkinter.Tk()

menu = Tkinter.Menu(root, tearoff=False)

def test(parent, index):
    def cb():
        print parent.entrycget(index, 'label')
    return cb

def build_menu(descr, parent):
    for item in descr:
        if isinstance(item, list):
            menu = Tkinter.Menu(root, tearoff=False)
            parent.add_cascade(label=item[0], menu=menu)
            build_menu(item[1], menu)
        else:
            indx = parent.index('last')
            if indx is None:
                indx = 0
            else:
                indx += 1
            parent.insert_command(index=indx, label=item,
                    command=test(parent, indx))

menudescr = [['File', [['Recent file list', ['a', 'b', 'c']]]]]
build_menu(menudescr, menu)

root['menu'] = menu
root.mainloop()

I don't see how is that different from Java, there are gtk bindinds
and qt bindings for Java too.

Doesn't that turn tkinter into the 'default widget set' ?

I don't understand the distinction you're drawing between Python
and Java.  What is Java's "default widget set"?  AWT?  JFC?  But
what about, for example, Thinlet?

Thanks Francesco, Guilherme -

you've both given me plenty to experiment with (and learn :-)). I have a
'partial' solution to what I'm trying to achieve (code snippet below) 
.........
                self.menubar = Menu(self.frm)

                # create the variable 'Action' sub-menu list
                # each sub-menu entry will have an (on)value which
corresponds to it's DB tablename (self.tables[value - 1])
                self.muVar=IntVar()
                self.mnth_mu=Menu(self.menubar, tearoff=0)
                self.on=IntVar()
                x=0

                # Strip out the month_yr part of the DB tablename (e.g.
04_April_09) and create a radiobutton entry on the
                # menu for each table that currently exists - a table is
only created at the start of a month
                for mnth in self.tables:
                        st=mnth.split("_",1)[1]
                        self.mnth_mu.add_radiobutton(label=st,
variable=self.muVar, value=self.on.get(), command=self.alt_cmd)
                        x+=1
                        self.on.set(x)

                # create the 'Action' menu list
                self.act_mu = Menu(self.menubar, tearoff=0)
                self.act_mu.add_command(label="Low stock - closing less
monthly sales", command=self.low_stock)
                self.act_mu.add_command(label="Profit and Loss",
command=self.pandl)
                self.act_mu.add_cascade(label="Stock/Order History",
menu=self.mnth_mu)
                self.act_mu.add_cascade(label="Top two sellers by quantity",
menu=self.mnth_mu)
                self.act_mu.add_cascade(label="Top two earners",
menu=self.mnth_mu)
                self.act_mu.add_cascade(label="Bottom two sellers by
quantity", menu=self.mnth_mu)
                self.act_mu.add_cascade(label="Bottom two earners",
menu=self.mnth_mu)
                self.menubar.add_cascade(label="Actions", menu=self.act_mu)

                # display the menu
                parent.config(menu=self.menubar)
........
               def alt_cmd(self):
                    # Determine the selection, match it to the correct
tablename then call appropriate function to generate the sql
                    print self.muVar.get()
........
The issue is that all the 'Actions' after and including Stock/Order history
will display the same sub-menu (self.mnth_mu).

The code as it stands enables me to identify which month has been selected
for a particular 'Action' but not which 'Action' it refers to i.e. works
fine if self.mnth.mu is used only once.

A solution is to create a separate menu for each 'Action' - I am averse to
doing this because the sub-menu for each action that requires a sub-menu is
identical and yes I'm a bit of a lazy programmer! 

I was hoping to - whatever the level of a menu - when a selection is made -
to be able to identify the 'Action' and the 'Month' selected.

I hope this makes sense ... I shall look into what you both have said
cheers

Well, my real suggestion would be to change this application. Don't
you think it is weird that when you select a month for a specific
action, all the other actions will have the same month selected ? How
can you know which one is active by looking in the menus ? Even if you
changed it to have multiple tcl variables, you still wouldn't know
which exact thing is active.

Nevertheless, I gave it a try and the code is below. It does create a
new menu for each action, but it is just about the same effort of
creating a single one.


import Tkinter

root = Tkinter.Tk()

def test(action):
    def cb():
        print month_var.get(), action
    return cb

def create_month_menu(action):
    month_menu = Tkinter.Menu(action_menu, tearoff=False)
    for month in ('Jan', 'Feb', 'Mar'):
        month_menu.add_radiobutton(label=month, variable=month_var,
                command=test(action))
    return month_menu

menu = Tkinter.Menu(tearoff=False)
action_menu = Tkinter.Menu(menu, tearoff=False)
month_var = Tkinter.StringVar()

for action in ('A1', 'A2'):
    action_menu.add_cascade(label=action, menu=create_month_menu(action))

menu.add_cascade(label='Actions', menu=action_menu)
root['menu'] = menu

root.mainloop()

Since the OP seemed to link too close Python to Tkinter ( or at list I read
it that way ) I just wanted to clarify that Tkinter
is not the only choice when it comes to GUI in python. I draw the parallel
because last time I worked with Java (which was some time ago ) Swing was
almost the only option (with AWT being obsoleted and other bindings being
non-exixtent ).

I don't see how, honestly. He started saying "Hi - am using python 2.6
and Tkinter 8.5.", how does that link too close Python to Tkinter ?
Plus, this is a tkinter list, I don't know what are you expecting
(hopefully not that people post offtopic questions just to show they
use another toolkit).

I entirely agree that Python supports a wealth of GUI toolkits;
'fact, I've mentioned before in publications that Python is ef-
fectively the single language with the broadest span in that
regard.

Well, my real suggestion would be to change this application. Don't
you think it is weird that when you select a month for a specific
action, all the other actions will have the same month selected ? 


yeah I know - I've used a radiobutton  to see if it could be used instead of
a cascaded menu. The 'partial' bit is that I was able to to identify the
selection through the use the variables but as you say - it is not a good
way to go about this.

I've just run your code and it is exactly what I'm trying to do :-D however
I ideally want to use add_cascade() instead of add_radiobutton() .. my
problem is that a menu object does not provide for use
of variables and so far, using variables is the only way I've managed to get
a 'partial' solution albeit a bad one!!

Therefore the solution I've been trying to achieve is what your code does
but using add_cascade().  Failing that a rethink of the app. 

thanks again
cheers

Did you mean add_command instead of add_cascade ? It is possible to do
what you want, the first code I pasted didn't use Tcl variables so
maybe you could try adjusting it to your needs.

Sorry my fault - have not explained it well - what I mean is the 'variable'
coption that is available in add_checkbutton() and
add_radiobutton() but not in add_cascade().

It is through the use of the 'variable' coption that the month selected is
determined - knowing the month that has been selected is crucial in
determining which function to run. I could not see a way of using a cascaded
menu and still determine the month selected.

Having said that - seeing the way that you have written your code (I must
say I do like!) - I reckon I've been approaching this from the wrong angle
and am fairly sure that I can adapt it to what I need - this I'll do. 

There is always the option to simplify it all e.g. include a menubutton on
the menubar from which a month can be selected then run all 'actions'
against that month - though not as flexible from a user perspective.

Will work on what you have shown me.
cheers

Subject: [Tkinter-discuss] Create Buttons on the fly
Message-ID: <7e7b6e9e0908310840g2f04364bj14ed42a39f4f4aa2@mail.gmail.com>

Hello all,
I have a long list of objects, which I print to a GUI.  I want to filter
this list, print the filtered list to the GUI, but maintain the ability to
look at the previous lists.

My program currently takes the list (L1), prints it to a Listbox, and adds a
button (B1) for the list.  Next, I filter the list, print the new filtered
list (L2 subset of L1) to the same Listbox (removing the elements of L1 not
in L2), and add an additional button for the new list. And so on...

How do I find a way to associate the old list L1 to the command for the
button (B1)?  Note, I do not want to create a separate command for each
button because I want to run an unlimited number of filters.  I need to have
B1 linked to L1, B2 linked to L2, B3 linked to L3, etc.

Here is some relevant code (n.b., the whole project is much larger, so this
is merely a snippet).

#n.b., L from the description above is all_entities.  So, L1 is
all_entities[1], etc.
#filter_group is an index tracking the current group to be filtered.

    #Filter the list
    def search_entities(self):
        tmp1 = askstring('Search Entity','Entity Type',initialvalue='gene')
        filtered = []
        #Create sublist
        for ent in self.backend.all_entities[self.filter_group]:
            if ent.etype.endswith("findthisstring"):
                filtered.append(ent)

        #Store sublist
        self.backend.all_entities.append(filtered)
        self.filter_group += 1
        self.add_filter_button()

    def add_filter_button(self):
        tmp = 'B%s' % self.filter_group
        filt = Button(self,text = tmp,command=self.fill_listbox(self))
        filt.grid(row=3,column=self.filter_group,sticky=E)
        self.fill_listbox()

    def fill_listbox(self):
       #clear listbox
       if self.ent_listbox.size() > 0:
            self.ent_listbox.delete(0,END)
        #Restore list box
        for ent in self.backend.all_entities[self.filter_group]:
            self.ent_listbox.insert(END,ent.name)

The way my code exists now, I would need to modify the variable filter_group
when I click a button.  How can I accomplish this?  How do I tell
filter_group to be 1 if I click button 1 and 2 if I click button 2?

Sorry if this post is long.  Let me know if you need more information.

The answer is implicit in <URL:
http://tkinter.unpythonic.net/wiki/Widgets/Button >, especially
in the section titled "Parameter-passing".  Is that enough of a
hint for you to reach the answer on your own?  Otherwise, I
expect one of us will make time over the next thirty hours or so
to provide an explicit coding.

That is very helpful.
I appreciate your expeditious response.

Thanks,
