All common dialogs appear to ignore the optional parent = parameter 

It seems it is because your code invoke the winfo_root() before the grid
manager finish is calculations.
and this command return a Null decimal string.

According to Tk manual "https://www.tcl.tk/man/tcl8.4/TkCmd/winfo.htm#M52" 

If you need the true width immediately after creating a widget, invoke
update to force the geometry manager to arrange it, or use winfo reqwidth to
get the window's requested width instead of its actual width.

This code works perfectly

self.update()

self.geometry("+%d+%d" % (self.parent.winfo_rootx()+50,
self.parent.winfo_rooty()+50 ) )

Thanks in advance for any help! I'm just learning Python and Tkinter. Can 
anyone suggest why this program does not insert 'some text' into text box 
t1 when the start button is clicked? No errors are thrown when I run the 
program in PyCharm

from tkinter import *

class Window(Frame):
    t1 = []
    def __init__(self, master=None)
        Frame.__init__(self, master)
        self.master = master
        self.master.title("My Title")
        StartButton = Button(self, text="Start", command=self.start, bg=
'#006ba6', fg="white")
        StartButton.grid(row=0, columnspan=3, sticky=(N, S, W, E))
        Label(self, text="Your Name").grid(row=1, sticky=(N, S, W, E))
        t1 = Text(self, height=2)
        t1.grid(row=1, column=1, sticky=(N, S, W, E))
        self.t1.insert( 0, 'some text')
        quitButton = Button(self, text="Quit", command=self.client_quit, 
bg='#006ba6', fg="white")
        quitButton.grid(row=5, columnspan=3, sticky=(N, S, W, E))
        self.grid(sticky=(N, S, W, E))

    def start(self):
        self.t1.insert(0, 'some text')

    def client_quit(self):
        exit()

root = Tk()
root.geometry()
app = Window(root)
root.mainloop()

I think your issue is that your list "t1" is not doing anything for
you.  Inside your __init__ method, "t1" and "self.t1" are not
referring to the same thing.  Your Text widget is bound to "t1", not
the list.  I am a relative newbie in tkinter, but apparently "0" is
not an allowed index.  "insert" inserts before the given index, which
in your case needs to be "END".

I don't see what this is doing.  It will not be the same as t1 in your
method below.

This needs to drop the "self" and use an appropriate index.  It should
be:  "t1.insert(END, 'some text')".

I am a bit confused about this, which dialogs do you mean exactly?

(...)

there are various problems here:
You do  self.t1.insert( 0, 'some text') , your text widget however is
"t1", self.t1 is an empty list, so your list after the button press will
look like ['some text', 'some text'] .
Next, if you try to insert a string into a text widget, you need to
specify the index with a construct like "line.character", so if you want
to insert something at the start of the first line, use 1.0 instead of 0,
otherwise a TclError will be thrown, as in:

>>> text.insert(0, 'foo')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "Tkinter.py", line 3236, in insert
    self.tk.call((self._w, 'insert', index, chars) + args)
_tkinter.TclError: bad text index "0"

Michael

the way you initialize the Text widget here effectiveley makes it into
self.t1 , so you will get an error when you try to grid() the widget,
because there is no t1. You will get the same error when the start()
function is called.
To make sure the code works as expected, you need to take care that the
widget is properly referenced, so it can be accessed later. The way to go
is something like:

     def __init__(self, master=None):
         Frame.__init__(self, master)
         self.t1 = Text()
         self.t1.grid()
         (...)

     def start(self):
         print('I am here')
         self.t1.insert(END, 'some text')


Best regards

Michael

Hi Everybody,

I like Tkinter a lot and am using it to create Gui driven Python tools for
my company. I was wondering if somebody could give me a current answer on
what the best way of writing unit tests is for Tkinter programs? I am
looking for a programmatic approach that I can automate at git commit time.
I looked at dogtail and PyUseCase? Are these tools current? What does
everybody else do?

Apologies for asking a question that I am sure has been asked several times
before, but I can't seem to find a good recent answer.

Thank you very much for the help,

James

Alan,
What are the extensions of the images you are asking 
about?  Some smart phone images I receive are jpg. 

If you go to my website, inqvista.com, and scroll thru the 
Image Management Link you can see a few images that 
are png's but others are available for tkinter,
