Display List as Multiline Label in TKinter
I have a Table i am generating using a List (Baseline_Data).
I can get this to print to the terminal fine using:
for row in Baseline_Data:
# Display List as Table
print('\t'.join(row))
What i cant get to work is for this to display in my Tkinter GUI. I found the best way to achieve this would be to generate a label and configure the text.
I have tried:
Import_Lab.config(text=("\t".join(row)))
Which only displays the last row of my List
Import_Lab.config(text=('\n'.join(row)))
Which does the same but displays it as a column
Import_Lab.config(text=(Baseline_Data))
Which displays the full List but as one long continuous line.
How do i display this List as a Multi-line Label ?
import tkinter as tk
from tkinter import ttk
from tkinter import *
root = Tk()
note = ttk.Notebook(root)
def Import_Button1_Press():
Baseline_Data = [
[' IM |', 'IM.Ser', 'Maj', 'Min', 'IIB.Ser', 'Maj', 'Min', 'ManfDate'],
['---------------------------------------------------------------------------'],
['1 - IM1 |', "12345", "22", "33", "12345", "55", "66", "123456"],
['1 - IM2 |', "12345", "22", "33", "12345", "55", "66", "123456"],
['1 - IM3 |', "12345", "22", "33", "12345", "55", "66", "123456"],
['1 - IM4 |', 'NA', 'NA', 'NA', 'NA', 'NA', 'NA', 'NA'],
['1 - IM5 |', "12345", "22", "33", "12345", "55", "66", "123456"],
['1 - IM6 |', "12345", "22", "33", "12345", "55", "66", "123456"],
['2 - IM1 |', "12345", "22", "33", "12345", "55", "66", "123456"],
['2 - IM2 |', "12345", "22", "33", "12345", "55", "66", "123456"],
['2 - IM3 |', "12345", "22", "33", "12345", "55", "66", "123456"],
['2 - IM4 |', 'NA', 'NA', 'NA', 'NA', 'NA', 'NA', 'NA'],
['2 - IM5 |', "12345", "22", "33", "12345", "55", "66", "123456"],
['2 - IM6 |', "12345", "22", "33", "12345", "55", "66", "123456"]
]
for row in Baseline_Data:
# Display List as Table
print('\t'.join(row))
Tab1 = ttk.Frame(note)
canvas1 = Canvas(Tab1, width=550, height=350)
canvas1.pack()
Tab2 = ttk.Frame(note)
canvas2 = Canvas(Tab2, width=550, height=350)
canvas2.pack()
Import_Button1 = tk.Button(Tab2, text = 'Import XML [Baseline]', width=25, height=2, command=Import_Button1_Press)
Import_Button_Window = canvas2.create_window(25, 40, anchor = 'w', window = Import_Button1)
Import_Lab = Label(Tab2, anchor=W)
Import_Lab_Window = canvas2.create_window(275, 175, anchor = 'center', window = Import_Lab)
note.add(Tab1, text = " Main ")
note.add(Tab2, text = " Baseline Data ")
note.pack()
root.mainloop()
Solution
You need to generate the complete string, with all the lines (rows of the table) and then pass it to the text argument, for example:
Import_Lab.config(text="\n".join("\t".join(row) for row in Baseline_Data))
For the table to display correctly, use a monospace font for that label.
from tabulate import tabulate
import tkinter as tk
from tkinter import ttk
def import_button1_press():
baseline_data = [
[' IM |', 'IM.Ser', 'Maj', 'Min', 'IIB.Ser', 'Maj', 'Min', 'ManfDate'],
['---------------------------------------------------------------------------'],
['1 - IM1 |', "12345", "22", "33", "12345", "55", "66", "123456"],
['1 - IM2 |', "12345", "22", "33", "12345", "55", "66", "123456"],
['1 - IM3 |', "12345", "22", "33", "12345", "55", "66", "123456"],
['1 - IM4 |', 'NA', 'NA', 'NA', 'NA', 'NA', 'NA', 'NA'],
['1 - IM5 |', "12345", "22", "33", "12345", "55", "66", "123456"],
['1 - IM6 |', "12345", "22", "33", "12345", "55", "66", "123456"],
['2 - IM1 |', "12345", "22", "33", "12345", "55", "66", "123456"],
['2 - IM2 |', "12345", "22", "33", "12345", "55", "66", "123456"],
['2 - IM3 |', "12345", "22", "33", "12345", "55", "66", "123456"],
['2 - IM4 |', 'NA', 'NA', 'NA', 'NA', 'NA', 'NA', 'NA'],
['2 - IM5 |', "12345", "22", "33", "12345", "55", "66", "123456"],
['2 - IM6 |', "12345", "22", "33", "12345", "55", "66", "123456"]
]
table = "\n".join("\t".join(row) for row in baseline_data)
import_lab.config(text=table)
root = tk.Tk()
note = ttk.Notebook(root)
tab1 = ttk.Frame(note)
canvas1 = tk.Canvas(tab1, width=850, height=650)
canvas1.pack()
tab2 = ttk.Frame(note)
canvas2 = tk.Canvas(tab2, width=850, height=650)
canvas2.pack()
import_button1 = tk.Button(
tab2, text='Import XML [Baseline]',
width=25, height=2,
command=import_button1_press
)
import_button_window = canvas2.create_window(
25, 40, anchor='w', window=import_button1
)
import_lab = tk.Label(tab2, font=('Consolas', 10), justify=tk.LEFT, anchor='nw')
import_lab_window = canvas2.create_window(
425, 350, anchor='center', window=import_lab
)
note.add(tab1, text=" Main ")
note.add(tab2, text=" Baseline Data ")
note.pack()
root.mainloop()
Another option to generate plain text tables easily is to use the tabulate package:
from tabulate import tabulate
import tkinter as tk
from tkinter import ttk
def import_button1_press():
baseline_data = [
[' IM |', 'IM.Ser', 'Maj', 'Min', 'IIB.Ser', 'Maj', 'Min', 'ManfDate'],
['---------------------------------------------------------------------------'],
['1 - IM1 |', "12345", "22", "33", "12345", "55", "66", "123456"],
['1 - IM2 |', "12345", "22", "33", "12345", "55", "66", "123456"],
['1 - IM3 |', "12345", "22", "33", "12345", "55", "66", "123456"],
['1 - IM4 |', 'NA', 'NA', 'NA', 'NA', 'NA', 'NA', 'NA'],
['1 - IM5 |', "12345", "22", "33", "12345", "55", "66", "123456"],
['1 - IM6 |', "12345", "22", "33", "12345", "55", "66", "123456"],
['2 - IM1 |', "12345", "22", "33", "12345", "55", "66", "123456"],
['2 - IM2 |', "12345", "22", "33", "12345", "55", "66", "123456"],
['2 - IM3 |', "12345", "22", "33", "12345", "55", "66", "123456"],
['2 - IM4 |', 'NA', 'NA', 'NA', 'NA', 'NA', 'NA', 'NA'],
['2 - IM5 |', "12345", "22", "33", "12345", "55", "66", "123456"],
['2 - IM6 |', "12345", "22", "33", "12345", "55", "66", "123456"]
