Tkinter, adding widgets in an embedded Frame widget in a Text widget

Question

I know we can add embedded widgets in a Text widget using Text method .window_create().But is it possible to add other widgets onto this embedded widget?

For example, I have a Text widget, I want to add a Frame widget under each line, and would like to use this embedded Frame widget as a container for adding e.g. Label widget to display features and annotations for specific part of the text.

How could I achieve, or is there an alternative way?

Here is some example code:

from tkinter import *

root = Tk()
myText = Text(root)
myText.pack()

text = """ACAACATACGAGCCGGAAGCATAAAG
TGTAAAGCCTGGGGTGCCTAATGAGT
GAGCTAACTCACATTAGGCTGAATTA
GGCGCGCCT"""

mylist = text.splitlines()

for row in range(len(mylist)):    
    myText.insert('end', mylist[row])
    myText.insert("end", '\n')
    myText.window_create('end', window=Frame(myText, width=180), stretch=1)
    myText.insert("end", '\n')

root.mainloop()

The above code will generate this:

With this example code above, how can I add additional widget (e.g. Labels) on those Frames, so that I can display descriptions on certain fragments of the text.

Thanks for helping!!

You add labels to the frame the same way you add labels to any other frame. Have you tried that? — Bryan Oakley
@ Bryan Oakley, sorry Bryan, I don't quite understand what you mean. There is no variable associated to the Frame object(s) in my example code, how to I refer them? Do you mean something similar as the answer posted below by @acw1668? Or would you please share an example? Thanks! — Zhenhua Xu
"There is no variable associated to the Frame object(s) in my example code, how to I refer them?" - by saving a reference to the frame in a variable. — Bryan Oakley

You can store the frames in a list and then use the list to access the individual frame that you want to add labels to it:

frames = []  # store the frames
for row in range(len(mylist)):    
    myText.insert('end', mylist[row])
    myText.insert("end", '\n')
    frames.append(Frame(myText, width=180)) # create frame and store it in frames
    myText.window_create('end', window=frames[-1], stretch=1)
    myText.insert("end", '\n')

# add a label to each frame
for i, frame in enumerate(frames, 1):
    Label(frame, text=f"Hello in frame #{i}").pack()
