I have below code which will create Label and Entry widgets. Also I created Scroll bar for this window but both scroll bars are not working.
Please let me know why the scroll bar is disabled. Did the code is doing wrong ?
Below is my code which will create 50 labels and entry widgets but still scroll bars are not enabled.

I couldn't find a solution to this problem anywhere on the internet.
I have given a scrollbar to a lengthy frame but when I make the frame shorter, I don't know why the scrollbar doesn't resize to the frame's length.
Above is a short program that represents the problem I am talking about. The program has 2 different pages, one with 100 buttons and the other with one button. You can switch between pages with any buttons and see that the page with one button is scrollable which shouldn't be.
Could you please provide a solution to how I could make the scrollbar resize to the frame's length? Thank you for your time.
The idea is that the scrollable canvas and its text widgets grow or fill the entire root/toplevel when I resize it.
I can do this if I work on Frames but for a scrollable frame you need to create a canvas widget and make it scrollable. Now I don't know if the problem is the canvas or the inserted widgets on the canvas?
import tkinter as tk
from tkinter import ttk
class ScrollableFrame():
def __init__(self, container, *args, **kwargs):
self.container = container
self.canvas = tk.Canvas(self.container, bg="green")
self.scrollbar = ttk.Scrollbar(self.container, orient="horizontal", command=self.canvas.xview)
self.scrollable_frame = tk.Frame(self.canvas)
self.scrollable_frame.grid(sticky="wesn")
self.scrollable_frame.bind("<Configure>", lambda e: self.canvas.configure(scrollregion=self.canvas.bbox("all")))
self.canvas.create_window((0, 0), window=self.scrollable_frame, anchor="nw")
self.canvas.configure(xscrollcommand=self.scrollbar.set)
self.canvas.grid(row=0, column=0, sticky="wesn")
self.scrollbar.grid(row=1, column=0, sticky="wesn")
if __name__ == "__main__":
root = tk.Tk()
root.configure(bg="grey20")
s = ScrollableFrame(root)
t = tk.Text(s.scrollable_frame)
t.grid(row=0, column=0, sticky="wesn")
t2 = tk.Text(s.scrollable_frame)
t2.grid(row=0, column=1, sticky="wesn")
root.mainloop()
I'm glad for help
Base on the requirement in the comment, you want to grow/shrink the two text boxes when the root window is resized. Below is the modified code with the necessary changes to achieve it:
import tkinter as tk
from tkinter import ttk
class ScrollableFrame():
def __init__(self, container, *args, **kwargs):
self.container = container
self.canvas = tk.Canvas(self.container, bg="green")
self.scrollbar = ttk.Scrollbar(self.container, orient="horizontal", command=self.canvas.xview)
self.scrollable_frame = tk.Frame(self.canvas)
self.scrollable_frame.grid(sticky="wesn")
self.scrollable_frame.bind("<Configure>", lambda e: self.canvas.configure(scrollregion=self.canvas.bbox("all")))
self.canvas.create_window((0, 0), window=self.scrollable_frame, anchor="nw", tags="scrollable")
self.canvas.configure(xscrollcommand=self.scrollbar.set)
self.canvas.grid(row=0, column=0, sticky="wesn")
self.scrollbar.grid(row=1, column=0, sticky="we") # fill horizontally only
# make self.canvas to fill all the available space of container
container.rowconfigure(0, weight=1)
container.columnconfigure(0, weight=1)
# resize self.scrollable_frame when self.canvas is resized
self.canvas.bind("<Configure>", lambda e: self.canvas.itemconfig("scrollable", width=e.width, height=e.height))
if __name__ == "__main__":
root = tk.Tk()
root.configure(bg="grey20")
s = ScrollableFrame(root)
# make the two text boxes to fill all the space of s.scrollable_frame
s.scrollable_frame.rowconfigure(0, weight=1)
s.scrollable_frame.columnconfigure((0,1), weight=1)
t = tk.Text(s.scrollable_frame)
t.grid(row=0, column=0, sticky="wesn")
t2 = tk.Text(s.scrollable_frame)
t2.grid(row=0, column=1, sticky="wesn")
root.mainloop()
So basically the logic is when the root window is resized, the canvas is resized to fill the root window. Then the frame (scrollable_frame) inside the canvas is resized to fill the canvas and finally the two text widgets are resized to fill the scrollable_frame.
I am using Python to parse entries from a log file, and display the entry contents using Tkinter and so far it's been excellent. The output is a grid of label widgets, but sometimes there are more rows than can be displayed on the screen. I'd like to add a scrollbar, which looks like it should be very easy, but I can't figure it out.
The documentation implies that only the List, Textbox, Canvas and Entry widgets support the scrollbar interface. None of these appear to be suitable for displaying a grid of widgets. It's possible to put arbitrary widgets in a Canvas widget, but you appear to have to use absolute co-ordinates, so I wouldn't be able to use the grid layout manager?
I've tried putting the widget grid into a Frame, but that doesn't seem to support the scrollbar interface, so this doesn't work:
mainframe = Frame(root, yscrollcommand=scrollbar.set)
Can anyone suggest a way round this limitation? I'd hate to have to rewrite in PyQt and increase my executable image size by so much, just to add a scrollbar!
Overview
You can only associate scrollbars with a few widgets, and the root widget and Frame aren't part of that group of widgets.
There are at least a couple of ways to do this. If you need a simple vertical or horizontal group of widgets, you can use a text widget and the window_create method to add widgets. This method is simple, but doesn't allow for a complex layout of the widgets.
A more common general-purpose solution is to create a canvas widget and associate the scrollbars with that widget. Then, into that canvas embed the frame that contains your label widgets. Determine the width/height of the frame and feed that into the canvas scrollregion option so that the scrollregion exactly matches the size of the frame.
Why put the widgets in a frame rather than directly in the canvas? A scrollbar attached to a canvas can only scroll items created with one of the create_ methods. You cannot scroll items added to a canvas with pack, place, or grid. By using a frame, you can use those methods inside the frame, and then call create_window once for the frame.
Drawing the text items directly on the canvas isn't very hard, so you might want to reconsider that approach if the frame-embedded-in-a-canvas solution seems too complex. Since you're creating a grid, the coordinates of each text item is going to be very easy to compute, especially if each row is the same height (which it probably is if you're using a single font).
For drawing directly on the canvas, just figure out the line height of the font you're using (and there are commands for that). Then, each y coordinate is row*(lineheight+spacing). The x coordinate will be a fixed number based on the widest item in each column. If you give everything a tag for the column it is in, you can adjust the x coordinate and width of all items in a column with a single command.
Object-oriented solution
Here's an example of the frame-embedded-in-canvas solution, using an object-oriented approach:
import tkinter as tk
class Example(tk.Frame):
def __init__(self, parent):
tk.Frame.__init__(self, parent)
self.canvas = tk.Canvas(self, borderwidth=0, background="#ffffff")
self.frame = tk.Frame(self.canvas, background="#ffffff")
self.vsb = tk.Scrollbar(self, orient="vertical", command=self.canvas.yview)
self.canvas.configure(yscrollcommand=self.vsb.set)
self.vsb.pack(side="right", fill="y")
self.canvas.pack(side="left", fill="both", expand=True)
self.canvas.create_window((4,4), window=self.frame, anchor="nw",
tags="self.frame")
self.frame.bind("<Configure>", self.onFrameConfigure)
self.populate()
def populate(self):
'''Put in some fake data'''
for row in range(100):
tk.Label(self.frame, text="%s" % row, width=3, borderwidth="1",
relief="solid").grid(row=row, column=0)
t="this is the second column for row %s" %row
tk.Label(self.frame, text=t).grid(row=row, column=1)
def onFrameConfigure(self, event):
'''Reset the scroll region to encompass the inner frame'''
self.canvas.configure(scrollregion=self.canvas.bbox("all"))
if __name__ == "__main__":
root=tk.Tk()
example = Example(root)
example.pack(side="top", fill="both", expand=True)
root.mainloop()
Procedural solution
Here is a solution that doesn't use a class:
import tkinter as tk
def populate(frame):
'''Put in some fake data'''
for row in range(100):
tk.Label(frame, text="%s" % row, width=3, borderwidth="1",
relief="solid").grid(row=row, column=0)
t="this is the second column for row %s" %row
tk.Label(frame, text=t).grid(row=row, column=1)
def onFrameConfigure(canvas):
'''Reset the scroll region to encompass the inner frame'''
canvas.configure(scrollregion=canvas.bbox("all"))
root = tk.Tk()
canvas = tk.Canvas(root, borderwidth=0, background="#ffffff")
frame = tk.Frame(canvas, background="#ffffff")
vsb = tk.Scrollbar(root, orient="vertical", command=canvas.yview)
canvas.configure(yscrollcommand=vsb.set)
vsb.pack(side="right", fill="y")
canvas.pack(side="left", fill="both", expand=True)
canvas.create_window((4,4), window=frame, anchor="nw")
frame.bind("<Configure>", lambda event, canvas=canvas: onFrameConfigure(canvas))
populate(frame)
root.mainloop()
Make it scrollable
Use this handy class to make the frame containing your widgets scrollable. Follow these steps:
create the frame
display it (pack, grid, etc)
make it scrollable
add widgets inside it
call the update() method
import tkinter as tk
from tkinter import ttk
class Scrollable(tk.Frame):
"""
Make a frame scrollable with scrollbar on the right.
After adding or removing widgets to the scrollable frame,
call the update() method to refresh the scrollable area.
"""
def __init__(self, frame, width=16):
scrollbar = tk.Scrollbar(frame, width=width)
scrollbar.pack(side=tk.RIGHT, fill=tk.Y, expand=False)
self.canvas = tk.Canvas(frame, yscrollcommand=scrollbar.set)
self.canvas.pack(side=tk.LEFT, fill=tk.BOTH, expand=True)
scrollbar.config(command=self.canvas.yview)
self.canvas.bind('<Configure>', self.__fill_canvas)
# base class initialization
tk.Frame.__init__(self, frame)
# assign this obj (the inner frame) to the windows item of the canvas
self.windows_item = self.canvas.create_window(0,0, window=self, anchor=tk.NW)
def __fill_canvas(self, event):
"Enlarge the windows item to the canvas width"
canvas_width = event.width
self.canvas.itemconfig(self.windows_item, width = canvas_width)
def update(self):
"Update the canvas and the scrollregion"
self.update_idletasks()
self.canvas.config(scrollregion=self.canvas.bbox(self.windows_item))
Usage example
root = tk.Tk()
header = ttk.Frame(root)
body = ttk.Frame(root)
footer = ttk.Frame(root)
header.pack()
body.pack()
footer.pack()
ttk.Label(header, text="The header").pack()
ttk.Label(footer, text="The Footer").pack()
scrollable_body = Scrollable(body, width=32)
for i in range(30):
ttk.Button(scrollable_body, text="I'm a button in the scrollable frame").grid()
scrollable_body.update()

I expect an expanded scrollable notebook/frame filled entire Tk() window.
Because the "ai" of stackoverflow don't allow use code from another thread, here is code https://pastebin.com/ykJGViAz
Inside init, do this instead
self.mainframe.grid(row=0, column=0, sticky="nsew")
self.TNotebook_Overview.grid(row=0, column=0, sticky="nsew")
This tells the frame to fill as much space as it needs
Just add this in the third line of init in the class overview:
self.mainframe.pack(fill = BOTH, expand = 1)
I have read a number of threads and other resources to try to find the correct way to handle this but I have not found anything that works with my application.
Here is what I am trying to accomplish.
When a query is completed and the insert of the data to a Listbox is done I cannot seem to get it to margin the data insert by 1 character space.
I am using pack() and I have read the tkinter manual for this and have tried each example available along with others found on various threads here.
The widget:
output = tkinter.Listbox(window_2, height = 20, font='Times 10',
width=42, bd=1, bg = '#FFD599', fg = '#9A0615', selectmode=SINGLE)
output.pack()
output.place(x=210, y=195)
I have tried padx and pady with pack() without success, although this works successfully with the Text widget. I have also attempted to use a few alternatives that I have found here on the site but all without success in margining the Listbox when the data is inserted.
Any advice?
pack's padx/pady and ipadx/ipady options don't affect the data that is inside the listbox. The listbox itself doesn't have any options to add an internal margin.
To get a margin around the inside of the listbox, what I normally do is give it a zero borderwidth and highlightthickness, and then place it in a frame with the same background color and let the frame be the border. You can then add any padding you want between the border and the listbox.
This is also convenient because you can put a scrollbar inside the frame, giving it the appearance that it is inside the listbox without actually being inside the listbox.
Example:
import tkinter as tk
root = tk.Tk()
root.configure(background="gray")
listbox_border = tk.Frame(root, bd=1, relief="sunken", background="white")
listbox_border.pack(padx=10, pady=10, fill=None, expand=False)
listbox = tk.Listbox(listbox_border, width=20, height=10,
borderwidth=0, highlightthickness=0,
background=listbox_border.cget("background"),
)
vsb = tk.Scrollbar(listbox_border, orient="vertical", command=listbox.yview)
listbox.configure(yscrollcommand=vsb)
vsb.pack(side="right", fill="y")
listbox.pack(padx=10, pady=10, fill="both", expand=True)
for i in range(100):
listbox.insert("end", "Item #{}".format(i))
root.mainloop()
here is a variation on the much appreciated answer by Bryan Oakley.
it uses ttk widgets instead of tk widgets
the scrollbar tracks your position in the list box when you scroll with the mouse
uses the oStyle.theme_use("clam") because it may look more modern...this can be commented out
'
import tkinter as tk
from tkinter import ttk
try: # allows the text to be more crisp on a high dpi display
