I am using tkinter and created a label with textvariable. What I want is to have let say top 5 customer listed in this one label. The customer list is from an excel file.
Part of my code:
import pandas as pd
import tkinter as tk
from tkinter import ttk
df = pd.read_excel('Sample.xlsx', "Sheet1")
class Application(tk.Frame):
def __init__(self, master=None):
super().__init__(master)
self.grid_rowconfigure(1, weight=1)
self.grid_columnconfigure(1, weight=1)
self.grid()
self.baseDown = tk.Frame(root, width=800, height = 400, background='#E6E6FA', relief = "groove", borderwidth = 2)
self.baseDown.grid(columnspan=7, row=1, rowspan = 4, pady = 1, padx = 2, sticky="wn")
self.BDown = tk.LabelFrame(self.baseDown, text = " Analysis ", width=800, height=400, background ='#E6E6FA', relief = 'ridge', borderwidth = 2)
self.BDown.config(font = ('Verdana', 8, 'bold'))
self.BDown.grid(columnspan=7, row=1, rowspan = 4, pady = 3, padx = 2, sticky="wn")
self.baseDown.grid()
self.cust_var = tk.StringVar()
self.lbl_custname = ttk.Label(self.BDown, textvariable = self.cust_var)
self.lbl_custname.config(font=('Segoe UI', 8), width = 100)
self.lbl_custname.grid(row=1, column=1, columnspan=3, pady = 1, padx = 2, sticky="nw")
top = df.nlargest(5, columns=['Value'])
for index, row in top.iterrows():
self.cust_var.set(row[top['Customer Name'].values.astype(str)])
root = tk.Tk()
root.configure(background = 'white')
#root.resizable(False, False)
app = Application(master=root)
app.mainloop()
The output is as below:
Customer1 NaN
Customer2 NaN
Customer3 NaN
Customer4 NaN
Customer5 NaN
Name: 20371, dType: Object
Customer list is correct, but I don't understand why NaN is there and why is the datatype appearing as well.
My excel file only carry 2 columns:
Customer Name
Value
You are setting the self.cust_var to the result of row[top['CustomerName'].values.astype(str)] 5 times.
If you want to show what you expect, you simply set the variable once (replace the for loop):
self.cust_var.set('\n'.join(top['Customer Name'].values))

I want to create a list of frames with further features like a button, label e.g.. but my issues are the size of the LabelFrame. If I put the LabelFrame in container it fits like I want to but it isn't scrollable any more. Any ideas?
from tkinter import ttk
import tkinter as tk
root = tk.Tk()
container = ttk.Frame(root)
canvas = tk.Canvas(container)
scrollbar = ttk.Scrollbar(container, orient="vertical", command=canvas.yview)
scrollable_frame = ttk.Frame(canvas)
scrollable_frame.bind(
"<Configure>",
lambda e: canvas.configure(
scrollregion=canvas.bbox("all")
)
)
canvas.create_window((0, 0), window=scrollable_frame, anchor="nw")
canvas.configure(yscrollcommand=scrollbar.set)
for i in range(50):
lf = ttk.Frame(scrollable_frame, text=i).grid(column=1, row=i)
frame_ip = tk.LabelFrame(lf, bg="white", text=i)
frame_ip.place(relwidth=0.95, relheight=0.2, relx=0.025, rely=0)
button_scroll1 = tk.Button(frame_ip, text="Start", bg="grey")
button_scroll1.place(relwidth=0.15, relx=0.025, relheight=0.15, rely=0.1)
container.pack()
canvas.pack(side="left", fill="both", expand=True)
scrollbar.pack(side="right", fill="y")
root.mainloop()
Here is your updated code with a Button, Canvas and Scrollbar inserted into each LabelFrame with grid manager.
I've also made the container resizable with row|column configure.
Seems to work fine.
import tkinter as tk
from tkinter import ttk
root = tk.Tk()
root.rowconfigure(0, weight = 1)
root.columnconfigure(0, weight = 1)
root.geometry("341x448")
container = ttk.Frame(root)
container.rowconfigure(0, weight = 1)
container.columnconfigure(0, weight = 1)
canvas = tk.Canvas(container)
scrollbar = ttk.Scrollbar(container, orient = tk.VERTICAL, command = canvas.yview)
scrollable_frame = ttk.Frame(canvas)
scrollable_frame.bind(
"<Configure>",
lambda e: canvas.configure(
scrollregion=canvas.bbox("all")))
canvas.create_window((0, 0), window = scrollable_frame, anchor = tk.NW)
canvas.configure(yscrollcommand = scrollbar.set)
for i in range(15):
L = ttk.LabelFrame(scrollable_frame, text = "Sample scrolling label")
L.grid(row = i, column = 0, sticky = tk.NSEW)
B = ttk.Button( L, text = f"Button {i}")
B.grid(row = 0, column = 0, sticky = tk.NW)
K = tk.Canvas(
L, width = 300, height = 100,
scrollregion = "0 0 400 400", background = "#ffffff")
K.grid(row = 1, column = 0, sticky = tk.NSEW)
S = ttk.Scrollbar( L, command = K.yview)
S.grid(column = 1, row = 1, sticky = tk.NSEW)
K["yscrollcommand"] = S.set
container.grid(row = 0, column = 0, sticky = tk.NSEW)
canvas.grid(row = 0, column = 0, sticky = tk.NSEW)
scrollbar.grid(row = 0, column = 1, sticky = tk.NS)
root.mainloop()
I'm studying GUI, so please understand my poor codes below.
I was trying to make a program which gets game-character's information. So if you press the 'search' button, the list would be shown below. But... it only shows about 11 names due to the window size. So i wanted to put a scrollbar for that area, but I just don't know how to link the scroll bar to control the area. I meant, the scroll bar itself has created, and it does scroll itself, but it doesn't scroll the window I wanted. I must have linked it wrong but... not sure.
Below is the minimized example code, but it's still quite long and crude. Sorry for that again.
If anyone can enlighten me, it would be really great help for this and my future works as well.

First, using grid() to put frame_buttons into the canvas will not affect the scrollregion of the canvas. Use canvas.create_window() instead.
Second, it is better to bind <Configure> event on frame_buttons and update canvas' scrollregion inside the bind callback. Then adding widgets to frame_buttons will automatically update the scrollregion.
Also note that you have created new scrollbar and put it at same position whenever search_chr() is executed. Better create the scrollbar only once outside the function.
I would like print all the information present in the excel data in new tkinter window
You can use Tkinter's grid.
For example, to create a simple excel-like table:
from Tkinter import *
root = Tk()
height = 5
width = 5
for i in range(height): #Rows
for j in range(width): #Columns
b = Entry(root, text="")
b.grid(row=i, column=j)
mainloop()
To print, consider the following example in which I make a button with Tkinter that gets some text from a widget and then prints it to console using the print() function.
from tkinter import *
from tkinter import ttk
def print_text(*args):
try:
print(text1.get())
except ValueError:
pass
root = Tk()
root.title("Little tkinter app for printing")
mainframe = ttk.Frame(root, padding="3 3 12 12")
mainframe.grid(column = 0, row = 0, sticky = (N,W,E,S))
mainframe.columnconfigure(0, weight = 1)
mainframe.rowconfigure(0, weight = 1)
text1 = StringVar()
text_entry = ttk.Entry(mainframe, width = 20, textvariable=text1)
text_entry.grid(column = 1, row = 2, sticky = (N,W,E,S))
ttk.Button(mainframe, text = "Print!", command =
print_text(text1)).grid(column = 1, row = 3, sticky = (E))
for child in mainframe.winfo_children():
child.grid_configure(padx = 5, pady = 5)
text_entry.focus()
root.bind('<Return>', print_text)
root.mainloop()
Can anyone help me why columnspan not having any effect in this code:
import tkinter as tk
root = tk.Tk()
frametop = tk.Frame(root).grid(row = 0, column = 0, columnspan = 2)
labeltest1 = tk.Label(frametop, text="A").grid(row = 0, column = 0)
labeltest2 = tk.Label(frametop, text="B").grid(row = 0, column = 1)
labeltest3 = tk.Label(frametop, text="C").grid(row = 0, column = 2)
framebottom = tk.Frame(root).grid(row = 1, column = 0)
labeltest4 = tk.Label(framebottom, text="Hello World").grid(row = 1, column = 0)
labeltest5 = tk.Label(framebottom, text="Hello World").grid(row = 1, column = 1)
labeltest6 = tk.Label(framebottom, text="Hello World").grid(row = 1, column = 2)
root.mainloop()
labeltest1, labeltest2, labeltest3 are being distributed in column similar to the widgets of framebottom. What I wanted is a grid of 3 columns inside a frame with a columnspan = 2 with the same row.
Something similar to this:
|| A | B | C ||
| Hello World | Hello World | Hello World |
The way your code is organized, the Frames have no effect; when you grid on the same line as the widget creation, None gets returned and stored in the variables you are using for the Frames, and Label. A consequence is that the labels are inserted directly into root.
The following does the same, with a placement of the labels per your request.
import tkinter as tk
root = tk.Tk()
tk.Label(root, text="A").grid(row=0, column=0, columnspan=2)
tk.Label(root, text="B").grid(row=0, column=2, columnspan=2)
tk.Label(root, text="C").grid(row=0, column=4, columnspan=2)
tk.Label(root, text="Hello World").grid(row=1, column=0, columnspan=3)
tk.Label(root, text="Hello World").grid(row=1, column=3, columnspan=3)
tk.Label(root, text="Hello World").grid(row=1, column=6, columnspan=3)
root.mainloop()
GUI appearance (osX):
def mouse_click(event):
#'reports' to both terminal and results text box
parent_name = Frame.winfo_parent(root)
parent = Frame._nametowidget(parent_name)
result = ("{0}: {1},{2}\n ".format('Clicked at', event.x, event.y))
print('clicked at',parent, event.x, event.y)
from tkinter import *
root = Tk()
root.title("Change Text")
root.geometry('700x500')
top=root.winfo_toplevel()
for rn in range(0,9): # rn = row number
top.rowconfigure(rn, weight=1)
top.rowconfigure(rn, weight=0)
for cn in range(0,5): # cn = column number
top.columnconfigure(cn, weight=1)
# FRAME 1
frame1 = Frame(root, borderwidth = 2, background = '#EFE0CD', relief = RIDGE,width = 25, height = 20)
frame1.bind("<Button-1>", mouse_click)
frame1.grid(column = 0, row = 0, columnspan = 2, rowspan = 3, sticky = N+S+E+W)
frame1_lbl = Label(frame1, text='Frame 1', font='comic-sans-MS 10 ', fg ='red', bg = '#EFE0CD')
frame1_lbl.grid(row=0, column =0)
# FRAME 2
frame2 = Frame(root, borderwidth = 2, background = '#CCC6B0', relief = RIDGE,width = 25, height = 20)
frame2.bind("<Button-1>", mouse_click)
frame2.grid(column = 0, row = 3, columnspan = 2, rowspan = 3, sticky = N+S+E+W)
frame2_lbl = Label(frame2, text='Frame 2', font='comic-sans-MS 10', fg ='red', bg = '#CCC6B0')
frame2_lbl.grid(row=0, column =0,)
root.mainloop()
I know that this is a really dumb question. How do I identify the Frame in which the mouse is clicked so that report prints clicked frame1 or frame2 at x y coordinates?. I found a bit about using winfo_parent but have obviously not used it properly.
Thank you
The event object that is passed in to the callback has a widget attribute which is a reference to the widget that got the event. So, event.widget is what you want to print.
