How exactly did you install it? Please describe the exact sequence of actions that you performed. Did you just start sbopkg, searched for "thonny", then installed it? If so, it's very likely that it's the wrong way to do it, in either 14.2 or 15.0. If you go to the corresponding page on SBo http://slackbuilds.org/repository/14.2/python/thonny/ you will see that it has build dependencies. Hence, you need to generate the queue file for it:

Code:

# sqg -p thonny

Then start sbopkg, load the queue for thonny and install all the packages, as in both thonny and its dependencies.

:( This proves that you just blindly copypasted the whole without thinking. You were supposed to do

Code:



bash-4.3$ python3

after you did

Code:



bash-4.3$ python

First would check the default python version, second would explicitly check if you have python3

Again, no details about how exactly did you install Python3. And this probably implies that you did not have it already installed for something else before thonny. Then that probably you didn't go through the queue file workflow mentioned above, otherwise python3 would've been installed when you ran the queue for thonny in sbopkg.

or something similar will work.

IMHO suggesting to install software provided by SBo via pip to somebody who's not very experienced (see my copypaste comment above) will only add more confusion. Your example command will work as root, mixing stuff installed for python3 via sbopkg from SBo and software for the same python3 installed directly via pip, which is a VERY bad thing. It's possible to install things via pip as regular user, but then the pip command requires an additional --user command line argument. Yet I'm not sure using pip is needed, as I said above.

Oh please, this is Slackware, not Debian. It doesn't split python into multiple packages, adding even more confusion. If python3 was installed correctly, via the SBo script for 14.2, it contains tk, just like the vanilla python2 package. Lack of tk in python3 means that probably python3 was installed differently, hence I asked OP above to provide more details.

So it seems it could be installed with :

Please, stop suggesting pip in this context. Slackware 14.2 was the stable version for many years. You don't imagine SBo shipped python3 with no tk, considering that vanilla python2 in Slackware doesn't split the python package? See above.

How do I configure python for Tk?

As per the final error in #12 above.

I'm guessing that the standard Python install does not use Tk. Tk is something unique to Thonny

That's exactly what I did. It seemed logical and has worked in the past.
I always understood the dependencies were all installed as a package when using sbopkg

Open a python3 shell, and see if you can import tkinter. If not what is the error.

Or just keep ignoring the advise you are given.

Edit:
https://docs.python.org/3/index.html
https://docs.python.org/3/library/tkinter.html

I removed Python3 and reinstalled it paying particular attention to the output. It was very fast but I did see mention of tk flash past but it still was not installed

You are new to python. You are going to have an impossible time, unless you start at step one, then 2...

Arch calls python3 python, Slack might call that python3. It's your box, find out.

DESCRIPTION

    Tkinter provides classes which allow the display, positioning and

    control of widgets. Toplevel widgets are Tk and Toplevel. Other

    widgets are Frame, Label, Entry, Text, Canvas, Button, Radiobutton,

    Checkbutton, Scale, Listbox, Scrollbar, OptionMenu, Spinbox

    LabelFrame and PanedWindow.

    

    Properties of the widgets are specified with keyword arguments.

I suppose by "in the past" you rather mean "for other software". This indeed works. For software with no build dependencies. For software with build dependencies, you need to install them explicitly yourself, even if you use sbopkg. Or make use of queues, as I explained above.

No, not with sbopkg.

Quote:

Not once have you posted the output of a python3 shell. You posted the output to a python2 shell. They are different.

@FlinchX says Slack calls python3.python3

Are you going to post that or not?

Code:

python3

Then you can see if you can import tkinter in that shell. I am going to guess that you don't have tk/tcl installed. tkinter wont work without it.

Or, you could check and see if you have that installed.

After you get/have python3 working, tk/tcl installed so that tkinter will work...

Here is a simple little test script to see if all is well, with tkinter.

test.py

Code:

#!/usr/bin/python



from tkinter import *

from tkinter import font

from tkinter import ttk

 

class A(Tk):

    def __init__(self,*args,**kwargs):

        Tk.__init__(self,*args,**kwargs)

        self.notebook = ttk.Notebook()

        self.geometry('600x600')

        self.add_tab()

        self.notebook.grid(row=0)

 

    def add_tab(self):

        tab1 = B(self.notebook)

        tab2 = C(self.notebook) 

        tab3 = D(self.notebook)

        self.notebook.add(tab1,text="Tab1")

        self.notebook.add(tab2,text="Tab2")

        self.notebook.add(tab3,text="Tab3")



class B(Frame):

    def __init__(self,name,*args,**kwargs):

        Frame.__init__(self,*args,**kwargs)

        self.label = Label(self, text="Info for Tab1")

        self.label.config(font=24, bg='blue', fg='yellow')

        self.label.grid(row=1,column=0,padx=50,pady=100)

        self.name = name

 

class C(Frame):

    def __init__(self,name,*args,**kwargs):

        Frame.__init__(self,*args,**kwargs)

        self.label = Label(self, text="Info for Tab2")

        self.label.config(font=24, bg='green', fg='white')

        self.label.grid(row=1,column=0,padx=100,pady=150)

        self.name = name

      

class D(Frame):

    def __init__(self,name,*args,**kwargs):

        Frame.__init__(self,*args,**kwargs)

        self.label = Label(self, text="Info for Tab3")

        self.label.config(font=24, bg='yellow', fg='black')

        self.label.grid(row=1,column=0,padx=150,pady=200)

        self.name = name

 

my_app = A()

my_app.mainloop()

You can make that executable run it, or

Code:

python3 ./test.py

Again, how exactly did you install it? Via sbopkg as well? Is it this Python 3? http://slackbuilds.org/repository/14.2/python/python3/

Yes. With sbopkg

@SAJM Did you have a full 14.2 install before you started to install SBo things?

Result:

EDIT

oops I just noticed I should have run this after the Tk issue was resolved!!

Im going to remove everything and start again in this order

1. Install Python3
2. Install Thonny

Paying particular attention to dependencies.
