Subject: [Tkinter-discuss] how do I pass variables when binding to a widget?
Message-ID: <q16gkm$l7k$1@blaine.gmane.org>

Hi
System: 	Linux,
Python Version:	3.6.7

I am trying to learn how to bind to a widget, and process the contents 
of the bound widget

here is my attempt at code:

#! /usr/bin/python3
from tkinter import *
import datetime

def NewAge(start):
     print(start)
     futureAge = start + 5
     calculated.delete(0,END)
     calculated.insert(0,futureAge)


master=Tk()
Label(master, text='present age').grid(row=0, column=0)
Label(master, text='age in 5 years').grid(row=1, column=0)
first=Entry(master)
first.grid(row=0, column=1)
calculated = Entry(master)
calculated.grid(row=1, column=1)
first.bind("<Return>", NewAge(first.get()))

Button(master, text='exit', command=master.destroy).grid(row=3, column=0)

master.mainloop()

I get the following traceback:

Traceback (most recent call last):
   File "./bind.py", line 19, in <module>
     first.bind("<Return>", NewAge(first.get()))
   File "./bind.py", line 7, in NewAge
     futureAge = start + 5
TypeError: must be str, not int

All hints & help greatly appreciated.


regards,
Chris Roy-Smith

here for some reason the traceback looks slightly different:

~$ python3 test4.py

Traceback (most recent call last):
  File "test4.py", line 24, in <module>
    first.bind("<Return>", NewAge(first.get()))
  File "test4.py", line 19, in NewAge
    futureAge = start + 5
TypeError: Can't convert 'int' object to str implicitly

What happens becomes a bit more obvious if you change your code a bit
like this:

  (...)
  first=Entry(master)
  first.grid(row=0, column=1)
  # add a default value in the first entry
  first.insert('end', 25)
  calculated = Entry(master)
  calculated.grid(row=1, column=1)
  first.bind("<Return>", NewAge(first.get()))
  (...)

Then the traceback here looks like:

~$ python3 test4.py
25
Traceback (most recent call last):
  File "test4.py", line 21, in <module>
    first.bind("<Return>", NewAge(first.get()))
  File "test4.py", line 8, in NewAge
    futureAge = start + 5
TypeError: Can't convert 'int' object to str implicitly

So, what happens is, that as soon as your bind() function call is
processed the NewAge() function is called with first.get() as argument.
Since first.get() will always return a string, trying to add an integer
value will of course cause an error.

To fix this you need to change the call to bind(), so that the second
argument is the function NewAge itself, not a *call* to that function, as
in:

  first.bind("<Return>", NewAge)

After the binding has been applied, each time the <Return> event occurs
on that widget, the NewAge function will be called by tkinter with an
Event object as argument. So the definition of the NewAge function might
for example look like this:

def NewAge(event):
    try:
        futureAge = int(event.widget.get()) + 5
        calculated.delete(0,END)
        calculated.insert(0,futureAge)
    except ValueError:
        event.widget.bell()

If you want to learn more about Events (and tkinter in general), John
Shipman's excellent tkinter reference is an invaluable source of
knowledge:

I hope this helps.

I am having a terrible time wrapping this under my head.

What is missing here to have the scrollbar working.

Everything is displayed fine.? But the slider of the scrollbar is full 
length. i.e. same height as outerframe.? which is same size as the canvas.

 ??? def setup(self):
 ??????? c = 0
 ??????? r = 0
 ??????? outer_frame = Frame(self, bg='red', padx=2, pady=2)
 ??????? outer_frame.pack()
 ??????? scrollbar = Scrollbar(outer_frame)
 ??????? scrollbar.pack( side = RIGHT, fill=Y )

 ??????? canvas = Canvas(outer_frame, height=100, 
scrollregion=(0,0,300,300), yscrollcommand=scrollbar.set)
 ??????? canvas.pack(side=LEFT, expand=YES, fill=BOTH)
 ??????? scrollbar.config(command=canvas.yview)

 ??????? for f in os.listdir(self.thumbnail_folder):

The canvas can only scroll things added to the canvas with the create_*
functions (create_image, create_window, create_line, etc). You cannot add
widgets to the canvas with pack, place, or grid, and then be able to scroll
them.

Message-ID: <1547946427.2245170.1638989256.2B81E47E@webmail.messagingengine.com>

Hi,

Is there any way to make a Label display every Unicode character, or are we just stuck until Tcl/Tk fully supports all of unicode? 

Here's my example code:
import tkinter as tk
from tkinter import ttk
root = tk.Tk()
ttk.Label(root, text='Test \U0001d306 String').grid(row=0, column=0)
root.mainloop()

And the exception:
_tkinter.TclError: character U+1d306 is above the range (U+0000-U+FFFF) allowed by Tcl

System: Linux, Python 3.6.7, Tk 8.6

Is there anything I can do to be able to display that character?

Thanks for any pointers.
-Ben

according to
https://groups.google.com/forum/#!topic/comp.lang.tcl/OJqYYzCgKQo
there is some work in progress with Tcl, otoh even if you install the
latest Tcl/Tk 8.7 it might be difficult to get past this TclError which
seems to be hardcoded into Tkinter (with Tcl I don't get any error here,
just a placeholder where the unicode character should be).

Michael

when I try to change your example a bit, like this:

l = ttk.Label(root)
l.grid()
l.tk.eval(l._w + ' configure -text "Test \U0001d306 String"')

there is actually some character displayed which looks similar to this
one: https://www.compart.com/en/unicode/U+1D306 , which I found rather
surprising since with Tcl I get only a placeholder. The same happens when
I replace your unicode character with the smiley \U0001f600 they used in
the page I referred to before. tk.eval appears to do some magic here.

tinkering a bit more I found another solution which seems more obvious,
however I was not able to get this working with Python3. With Python2
when I do the following:

from Tkinter import *
import ttk

root = Tk()
l = ttk.Label(root)
l.pack(padx=40, pady=40)

s = u'Test \U0001d306 String'
s1 = s.encode('utf-8')
l.configure(text=s1)

root.mainloop()

the label's text looks like expected. Maybe that is just the same "magic"
that tk.eval applies. It does not seem to be that easy with Python3
though, apparently I missed some of the subtleties with Python3's unicode
handling mechanisms.

Thanks so much for your replies!

Here's my little test script, with trying what you wrote, and the results I got (all on python 3):
import tkinter as tk
from tkinter import ttk
root = tk.Tk()
l = ttk.Label(root)
l.grid(row=0, column=0)
text = 'Test \U0001d306 String'

#l.configure(text=text)
#  Result: _tkinter.TclError: character U+1d306 is above the range (U+0000-U+FFFF) allowed by Tcl

#l.configure(text=text.encode('utf8'))
#  Result: no exception, but wrong characters show up

l.tk.eval(l._w + f' configure -text  "{text}"')
#  Result: works!

root.mainloop()

So, tkinter maintainers, would there be a way to build this into tkinter, so it transparently handles all unicode characters? If so, would there be interest in patches for it?

the same here.

I tried to investigate a bit further and found this thread which seems
to more or less address this issue:

https://bugs.python.org/issue13153

It looks like the Tkinter maintainers are waiting for Tk 9.0 to come to
life which is supposed to introduce full unicode support.
There seem also to be some issues with different systems not behaving
exactly alike.

I also found a thread where a couple of workarounds are suggested:

https://stackoverflow.com/questions/40222971/python-find-equivalent-surrogate-pair-from-non-bmp-unicode-char

however none of these seem to work here ?

> If so,

Of course you can try.
Personally I would not bother (even if I had the skills to provide a
patch :)

I have Anaconda 3 with Python 2 and 3 environments on a MacBook running High Sierra.
One section of a program creates rectangles on a canvas (plotting GPS data points). Binding <Button-1> to a rectangle works fine (displays info about the point when clicked), but binding to <Button-3> doesn't work (it should "zap" the point out of the list and redraw the plot). The function for zapping never gets called, and there's no errors in the Terminal/xterm. It doesn't work with the Python 2 or 3 environment. Tcl/Tk versions are 8.6/8.6 in both environments. Shift-clicking, control-clicking, shift-control-clicking on the canvas or created items seems fine. Just this <Button-3> deal doesn't.

The same code runs fine in an Anaconda Python 3 environment in CentOS (using VMWare).
A Python package we make for our programs on the Mac (and one for Linux) with Python 2.7.9 Tcl/Tk 8.6/8.6 which starts XQuartz on a Mac when we start a Tkinter program is fine (it's what some are trying to replace with this whole Anaconda stuff).
Python 3 on Win10 works fine.

There is some old chatter about anaconda/conda Tkinter not being great on Macs on the net, but I've never seen a solution to get Anaconda to use a different Tcl/Tk library. The Anaconda Tkinter looks like junk. Apple's Tcl/Tk/Tkinter has never worked/looked well.

Anyone seen this <Button-3> business? Any ideas? Thanks!

Bob

This is handy. Instead of <Button-3> stock/default/unfiddled-with Anaconda Tkinter is calling it <Button-2>. My Tkinter programs have been around since 2004. I've never had to watch for <Button-2>. It must be in some configuration file somewhere, but I'll just watch for it. Don't want the user to have to mess around and change things.

Never mind. :)

Hi, we're Apple.  We know that your existing code is working fine, but we're going to change things up for no good reason.  Wanna buy a new underpowered Mac?

Unfortunately, it doesn't only apply to Tkinter and Python.

Haha! I have two late-2012 mini's, two mid-2012 MacBooks, a mid-2010 27" iMac, and two not new iPads that I can't type fast enough on to keep up with. Oh, and a Raspberry Pi in the mail. :)

I think this is an Anaconda thing. Other Tkinters on macOS seem to work fine, except, like I said, Apple's version (the one that comes with the OS). It has never been good. It looks like half-drowned Aqua, some Radiobutton groups don't behave, and it used to throw a fit over simple exit() commands.

Oh well, it's just a bunch of if-statements to fix it. It keeps you on your toes. :)
