Message-ID: <44563200.4030608@post.cz>

Hi,

I dont know how to dynamically add items to optionmenu.
I found this 
http://aspn.activestate.com/ASPN/docs/ActiveTcl/iwidgets/optionmenu.n.html 
insert method,  but it is not working or wrong done  by me.

w = OptionMenu(master, variable, *OPTIONS )
w.insert(1,"something")

Neither dir(w) nor print w.config() didnt help much.

Thank you

Hi Pavel,

you can access the OptionMenu's Menu by its 'menu' key:

>>> from Tkinter import *
>>> root = Tk()
>>> s = StringVar()
>>> s.set('eggs')
>>> o = OptionMenu(root, s, 'eggs', 'spam', 'foo', 'bar')
>>> o.pack()
>>> o['menu'].insert('end', 'command', label='blah')

I hope this helps

Michael

Just found there is another trouble with this. Maybe I could help 
myself, but dont know how to get from tk documentation what you have 
written - how to know why "command" should be there, why ["menu"], etc.

Anyway, I have:

w = OptionMenu(root, var,u"one", u"two", u"...",command=ok)
w.pack()
w["menu"].insert(2, "command", label=u"three")

When I choose "three" then, the function 'ok' is not called. It must be 
another argument in last line, I think.


Thank you

Hi Pavel,

the  "menu" key is created in Tkinter's OptionMenu class to give us access
to the Menu subwidget; optionmenu["menu"] is equivalent with optionmenu.__menu .
"command" is there to tell tk what to insert into the menu; try:

    optionmenu["menu"].insert('end', 'blah')

and you get a TclError:

    _tkinter.TclError: bad menu entry type "blah": must be cascade, checkbutton, command, radiobutton, or separator


> Anyway, I have:

Oops, you are right. A look at Tkinter.OptionMenu shows that it is not that trivial.
Tkinter wraps the command in its internal _setit class, so it should actually be:

    from Tkinter import _setit
    w['menu'].insert('end', 'command', label='blah', command=_setit(var, 'blah', ok))

The arguments for the _setit constructor are: _setit(variable, value, callback) .

Not very nice, indeed. Maybe it would be a nice improvement to Tkinter to add at least
an insert() and a delete() method to Tkinter.OptionMenu .

If you do not want to use the "hidden" _setit() you might define another callback for the inserted items:

    def ok_new(value):
        var.set(value)
        ok(value)

    w['menu'].insert('end', 'command', label='blah', command=lambda : ok_new('blah'))

Maybe it is even nicer not to use an OptionMenu command at all and use a trace callback for the variable instead:

>>> v = StringVar()
>>> v.set('a')
>>> def ok(*args):
...     print v.get()
... 
>>> v.trace('w', ok)
'-1216076380ok'
>>> om = OptionMenu(r, v, 'a', 'b', 'c')
>>> om.pack()
>>> om['menu'].insert('end', 'command', label='foo', command=lambda : v.set('foo'))

At least you do not need a second callback this way.

I hope this helps

Michael

this works with me even without new ok_new - with the old one:

    w['menu'].insert('end', 'command', label='blah', command=lambda : ok('blah'))

Hello, I'm new to this list. I've come in search of some answers to 
questions I hope I can articulate enough to be understood.

I would like to know how one would create a button that when clicked would 
clear the entire set of widgets (including the clicked button itself) and 
then display a whole new set of widgets.

The goal is to write a program that has about 6 different steps the user 
goes through to submit information. So for instance the first frame would 
welcome the user and display a "Click to Continue" button. When the button 
is clicked, the widgets would all disappear and be replaced by a new set of 
widgets. When these widgets are finsihed being used and the "Continue" or 
"Submit" button is clicked, again a new set of widgets would replace the 
old...and so on.

I am lost as to how I would design a class(?) that would carry out such a 
task. Ultimately, when the last set of widgets is finished, the program 
would revert back to the first set of widgets.

Is what I am asking clear? Any help would be appreciated.

Peter.

It's certainly feasible.  Before answering the technical
question, I recommend a moment more of discussion.

*My* first reaction to your description is that your users
might like a tabbed display, where finishing the interaction
with one tab automatically activates the next.  How does 
that sound to you?  My general experience is that it's
disquieting to users to erase an entire application display,
to start over with a new set of widgets; they do better with
an indication of an unchanging "foundation" that structures
the display and interaction.

I am not sure that it solves your question but the example program
tt095.py at the link
http://www.ferg.org/thinking_in_tkinter/all_programs.html
performs such a thing. it can suggest you a way to succeed your aim.

Thanks to Olivier for the sample structure. I think I understand it although 
I'm not very familiar with 'lambda'. Now Cameron has brought up a good 
point. By the way, this is an end-of-semester project for students. I am 
teaching Python for the first time to a high school class - so my knowledge 
is certainly limited. We have created a few simple programs but all have 
been command line. So ultimately the goal is simply to learn what GUIs are 
and play around, not to create anything professional. But Cameron's point is 
interesting. That is, have a set of tabs that display where in the process 
of the program the user is. This way they know how far they easily have a 
visual hold on how far they have to go and how far they've been. Of course, 
these tabs would not be clickable. I would want the buttons to cause the 
switch. I think I like that idea. Does it fit with the structure that 
Olivier offered below?

import Tkinter as tk
def change_frame(i, j):
    frames[i].pack_forget()
    frames[j].pack()

frames = []

r = tk.Tk()

#frames that you fill with your widgets
f1 = tk.Frame(r)
tk.Button(f1, command=lambda :change_frame(0,1),text='go to step 1').pack()

f2 = tk.Frame(r)
tk.Button(f2, command=lambda :change_frame(1,2),text='go to step 2').pack()

f3 = tk.Frame(r)
tk.Label(f3, text = 'step2').pack()

frames = [f1,f2,f3]

f1.pack()
r.mainloop()

It does not change the value of the variable, so the ok() callback will have to do this, like

    def ok(value):
        var.set(value)
        (...)

Now, I forgot about this solution, maybe the easiest of all.

Maybe you could use a Pmw.NoteBook and disable the tab buttons, like this (untested):

from Tkinter import *
import Pmw

root = Tk()
Pmw.initialise(root)

nb = Pmw.NoteBook(root)
nb.pack(side='top', fill='both', expand=1)

def next_page():
    pages = nb.pagenames()
    current = nb.getcurselection()
    # maybe more testing and changing the button's text here
    if current == pages[-1]:
        nb.selectpage(pages[0])
    else:
        nb.nextpage()

b = Button(root, text='Next page', command=next_page)
b.pack(side='bottom')

firstpage = nb.add('firstpage', tab_text='First page', tab_state='disabled', tab_disabledforeground='black')
(...)# add widgets and more pages

root.mainloop()

I hope this helps

Message-ID: <S377199AbWEDMdX/20060504123323Z+12856@ams016.ftl.affinity.com>


EHLO! Anyone have code showing how to reference many individual Canvas 
objects? I've built a large grid of ovals. I plan to have each oval change 
fill color numerous times based on various changing array values. I haven't 
yet successfully referenced these oval objects. Examples I've seen are all 
b1=canvas.create_oval() or similar. I thought tags might be an option, if I 
could serialize a tag specific to each oval... I'm used to thinking like 
this: 

for i in range(1,number+1)
n[i] = canvas.create_oval()
and
if variable[i] == "blue" then canvas.n[i].config(fill='blue') 

or something. Unfortunately that doesn't work --> SyntaxError: invalid 
syntax hehe 

HELP ME OBI-WAN!! YOU'RE MY ONLY HOPE!!

instead of this, there should be something like

all=[]
for i in range(1000):
    x,y=random.randint(0,X), random.randint(0,Y)
    o=canvas.create_oval((x,y,x+10,y+10), fill='red')
    all.append(o)

no, again, if you want to change color of 578th :-) oval, do it this way:
canvas.itemconfig(all[578-1], fill='pink')

Hi all,

 

I prepared a GUI which contains lots of buttons. Instead of defining
each of them one by one, I want to write a function that gets the
parameters and create a button.(Each one calls same function for
buttonclick event) Is it possible? If it is, can you give me a simple
example?

 

Thanks,

Hi Ilknur,

maybe you mean something like

    buttons = []
    r = 0
    c = 0
    for i in range(100):
        b = Button(master, text=i, **kw)
        b.grid(row=r, column=c)
        buttons.append(b)
        c += 1
        if c > 10:
            c = 0
            r += 1

I hope this helps

Hi Michael,

Actually my aim is a little bit different. I put one of the buttons in
my code;

        button_name = "menu"
        self.menu = Button(self.mycontainer,
                             command=lambda
                             arg1=button_name:
                              self.writecommand(arg1) 
                             ) 
        self.menu.configure(text="menu")
        self.menu.grid(row=2, column=0)
        ch = "<m>"
        self.menu.bind(ch,
                       lambda
                       event, arg1=button_name:
                       self.writecommand(arg1)
                       )

This part repeatedly occurs in my code for different buttons, but those
buttons placed in a different frames (not each in one, group by group)

For each button, button_name, configuration and geometry are changing.
It can be divided 2 or more functions if it can be achieved in any way. 

Thanks,

ilknur

In this example program, the canvas item is moved in the direction
indicated by the arrow key(s) pressed.  It works by setting a "dx" value
when Left or Right is pressed, and then setting "dx" back to 0 when one
of those keys is released.  Approximately each 20ms the dx and dy values
are added to the location of the box, and it's moved on the canvas using
coords().  It's probably a good idea to set dx and dy to 0 when you see
a <FocusOut> event, because when you lose focus you may not see all the
KeyRelease events for keys that were pressed at the time.

import Tkinter

x = y = 150
dx = dy = 0

def wrap(v, l):
    v = v % l
    if v < 0: return v + l
    return v

def update():
    global x, y
    x = wrap(x + dx, 300)
    y = wrap(y + dy, 300)
    c.coords(item, (x-5, y-5, x+5, y+5))
    c.after(20, update)

def set_dx(v):
    global dx; dx = v
def set_dy(v):
    global dy; dy = v


t = Tkinter.Tk()
t.bind("<KeyPress-Up>", lambda e: set_dy(-3))
t.bind("<KeyPress-Down>", lambda e: set_dy(3))
t.bind("<KeyPress-Left>", lambda e: set_dx(-3))
t.bind("<KeyPress-Right>", lambda e: set_dx(3))
t.bind("<KeyRelease-Up>", lambda e: set_dy(0))
t.bind("<KeyRelease-Down>", lambda e: set_dy(0))
t.bind("<KeyRelease-Left>", lambda e: set_dx(0))
t.bind("<KeyRelease-Right>", lambda e: set_dx(0))

c = Tkinter.Canvas(t, width=300, height=300)
c.pack()
item = c.create_rectangle((-1,-1,-1,-1), fill="blue", outline="white")

update()
c.mainloop()

Hi all,

Let's say you had the following class below (MakeChoice) that was used to 
cast a vote. When the program is running, eventually the user will confirm 
choices made through some sort of "SUBMIT" button. When that button is 
clicked, we want the selected value (on a few sets of radio buttons) to be 
written to a file. What is the container of the currently selected value and 
how does one have that value be written to a file when a button is clicked?

I hope my question is clear.

Thanks!

Hi Peter,

do you mean something like this:

def create_widgets(self):
    (... snip ...)
    self.submit_button = Button(self, text='Submit', command=self.submit)
    self.submit_button.grid(row=8, column=0)

def submit(self):
    f = open(your_filename_here, 'w')
    f.write(self.current_selection_get())
    f.close()

The value of the StringVar is updated automatically each time the user changes the selection.

I hope this helps

Michael

Hi Peter,

do you mean something like this:

def create_widgets(self):
     (... snip ...)
     self.submit_button = Button(self, text='Submit', command=self.submit)
     self.submit_button.grid(row=8, column=0)

def submit(self):
     f = open(your_filename_here, 'w')
     f.write(self.current_selection_get())
     f.close()

The value of the StringVar is updated automatically each time the user 
changes the selection.

I hope this helps

Michael

Message-ID: <79CD3DAD56583A4298D4941761CF687A448F42@cabottrexch.cabot.local>

Hi all,

 

I am trying to call my function by keypress. Some specific keys will be
assigned to some buttons. All widgets are created in a class. I wrote
the code as below:

 

    functionalkeys=("Left", "F1",...)

 

    def assignkey(self, event):

        if event.keysym not in self.functionalkeys:

            return

        self.callcommand(event.keysym)

        

   

    def callcommand(self, arg1):

        if arg1=="Left":

            self.writecommand('left')

 

        if arg1=="F1":

            self.writecommand('menu')

 

         ..........

        else:

            return 

 

and bind assignkey() to my buttons,

 

        self.menu=Button(...)

        self.menu.bind("<KeyPress>", self.assignkey)

 

this is working if I focused on the button, otherwise no action. I also
bind keypress event to my main frame, but it is also not working. I am
new for learning tk and most probably I am doing some basic thing wrong
but I could not find it:-( Is there anyone to tell me how can I call the
function without focusing the related button?

 

Thanks....

Hello Ilknur,

you need focus to get key events.
So normally you set focus for the parent of all buttons
(or the toplevel widget)
and also bind the command to that widget.
So:

  self.focus_set ()
  self.bind ( '<KeyPress>', self.assignkey )

in the __init__ of your class should work.
(your class needs to be a subclass of some widget, for example Frame)

Hope this helps,

Hi all,

 

I have a problem with toplevel window. It is created within a function
and I am calling that function by button press. I have created 4 buttons
that call same toplevel creating function. For the first call, there is
no problem. The toplevel window is created and get the arguments. But
the other call for that function results with an error message like;

 

"Toplevel instance has no __call__ method"

 

I could not solve what is the problem with it? What should I do to solve
the problem?

 

Thanks,

Hi Ilknur,

can you show us the code and a complete traceback, otherwise we can only guess.
The error message you described can be reproduced by the folllowing code snippet:

>>> t=Toplevel()
>>> t()
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
AttributeError: Toplevel instance has no __call__ method
>>>

so maybe the problem is the name you give to your Toplevel instance.

Michael

Hi Ilknur,

self.newkey is the name of the method that creates the Toplevel window, if you name the window self.newkey, too,
you override the method. Now when in your self.Button_Press() method the call to self.newkey() occurs,
you actually try to "call" the newly created Toplevel window which leads to the error message you saw.



 however, still I could not reach my aim. As you will see below, I could not assign self.userkey which is gotten from the user on toplevel window, to the userdefinedkey[] array. the aim is, at first click of a key should result with a toplevel window that gets the key parameter from the user. the other press of the same key should result by calling a different function with the parameter taken. there are more than one such a key on my GUI. I hope, I can explain my aim and problems:) thanks from now...

The problem here seems similar, if I understand you correctly. Each call to self.newkey() overrides a bunch of
variable names.
I think a better approach would be to write a separate class for your dialog window; if I understand the use
of your dialog window correctly, it is probably the best (and easiest) to use an askstring() dialog from the
tkSimpleDialog module, e.g.:

    (...)
    # do not forget to make the list a class attribute first
    self.userdefinedkeys = ['', '']
    # define the buttons like this:
    self.key1 = Button(self.mycontainer, text="Key1", command=lambda index=0 : self.button_press(index))
    (...)

    def button_press(self, index):
        if self.userdefinedkeys[index]:
            # alternative callback here
            print self.userdefinedkeys[index]
        else:
            self.userdefinedkeys[index] = tkSimpleDialog.askstring("Enter new key", "Key name:")

I hope this helps

Subject: [Tkinter-discuss] Scroll a table, but not the first two rows?
Message-ID: <20060531082340.GQ17400@kira.niekel.net>

Hi,

I'm trying to build a window that has a table with multiple columns. I'm
using Pmw.ScrolledFrame now, creating the table with the
.grid(row=N,column=N). This works quite good, but when more rows appear
than fit in the window, the header of the column scrolls off. 

Is it possible to have the headers above the columns not scroll, but scroll
the data below it? The columns and their header should be aligned properly.

Thanks,
Chris Niekel

Why don't you separate the table from the header? The header should be *outside* the ScrolledFrame, so it's not scrolled

Then the grids are different, and the columns are not aligned anymore. Or
is there a way to force that?

Hi Chris,

maybe you can calculate the needed width for the header and the associated column and then
configure both to have the same width. If you bind this method to <Configure> events for
both the header and the column you should be able to make sure that the width will
be updated every time the needed width of the column changes.

I hope this helps

just curious, why not use the MCListbox widget instead of hand-rolling
your own widget using ScrolledFrame?

as a bonus, the MCListbox has settable widths for the columns.   You
could create two of them inside a frame, use the top one for your
headers,and the bottom one for data.  You should be able to find the
widget here:

That's how I manage it. It's rather ugly, but it works. I sure wish 
Tkinter had a nice table widget.

Anyway, here's a code fragment (using bare Tkinter; I don't use pmw). 
The basic architecture (which is a bit weird and perhaps not ideal) is:
- The main widget produces a title frame, the vertical scroll bar and 
the scrolled table.
- The scrolled table is implemented as a widget that not only creates 
the main table, but also fills in the titles in the title frame. The 
code fragment is from this latter widget (and the title frame was passed 
in as an argument to __init___):

    def _addTitle(self, text, col):
        """Create and grid a title label and two associated
        width measuring frames (one in the title frame, one in the main 
frame).
        
        Inputs:
        - text  text for title
        - col   column for title
        """
        strWdg = Tkinter.Label(self._titleFrame, text=text)
        strWdg.grid(row=0, column=col)
        titleSpacer = Tkinter.Frame(self._titleFrame)

To see the whole thing, download TUI source from here
<http://tycho.apo.nmsu.edu:81/TUI-images/>
and look at TUI/TUIMenu/Permissions/
(PermisWindow.py imlements the high-level window;
PermisInputWdg.py implements the scrolled table)

Hmmm; I take it that <URL: http://tkinter.unpy.net/wiki/Table >
isn't for you.  On the other hand, you might combine <URL:

Nice tip!  Sure opens up the spectrum for Tkinter, by allowing us to make
better use of the wide range of Tcl widgets without having to take on the
