here is a picture of what i want to be:
scrollbar
Actual code:
lb = Listbox(self.master, width=120, height=6)
scrollbar = Scrollbar(self.master, orient="vertical",command=lb.yview)
scrollbar.pack(side="right", fill="y")
lb.config(yscrollcommand=scrollbar.set)
scrollbar.config(command=lb.yview)
lb.place(x=5,y=5)
Thanks!
You can create a new frame with listbox and scrollbar in it:
from tkinter import *
root = Tk()
root.geometry('500x300')
frame = Frame(root)
frame.place(x = 5, y = 5) # Position of where you would place your listbox
lb = Listbox(frame, width=70, height=6)
lb.pack(side = 'left',fill = 'y' )
scrollbar = Scrollbar(frame, orient="vertical",command=lb.yview)
scrollbar.pack(side="right", fill="y")
lb.config(yscrollcommand=scrollbar.set)
for i in range(10):
lb.insert(END, 'test'+str(i))
root.mainloop()
or since you're using place (which is not recommended), you can simply calculate the position of the scrollbar. grid would be the best layout manager in this case.
The problem is if you use only the 'place' positioning, the scrollbar doesn't appear.
The solution is to make two frames - one master frame with a widget scrollbar and
a second frame inside the master frame, where you can get the listbox. The frames can be positioned with place, the widget inside the frames with pack or grid.
Below is my source code, what works perfectly.
from tkinter import *
root = Tk()
root.geometry('500x300')
frame1 = Frame(root)
frame1.place(x = 10, y = 5,width=100,height=100) # Position of where you would place your listbox
frame1a=Frame(master=frame1)
frame1a.place(x=0,y=0,height=100,width=100)
lb = Listbox(frame1a, width=50, height=6)
lb.grid(row=0,column=0 )
scrollbar = Scrollbar(frame1, orient="vertical",command=lb.yview)
scrollbar.pack(side="right", fill="y")
lb.config(yscrollcommand=scrollbar.set)
for i in range(10):
lb.insert(END, 'test'+str(i))
root.mainloop()

Been staring at this code for so long, I can't see what is wrong with it.
When I run it, I get the listbox and OK button as I expect, but the scrollbar appears in the middle
of the listbox widget and doesn't actually scroll.
import tkinter as tk
def confirm_selection():
selection = sensor_listbox.get(sensor_listbox.curselection())
print("Selected:", selection)
root = tk.Tk()
root.title("USGS Data To Download From Glovis Scenelist")
w = 730 # width for the Tk root
h = 500 # height for the Tk root
ws = root.winfo_screenwidth() # width of the screen
hs = root.winfo_screenheight() # height of the screen
x = (ws/2) - (w/2)
y = (hs/2) - (h/2)
root.geometry('%dx%d+%d+%d' % (w, h, x, y))
#create listbox and scrollbar
sensor_listbox = tk.Listbox(root, height=3,width=20)
sensor_listbox.grid(row=0, column=2)#,columnspan=3)
sensor_scroll = tk.Scrollbar(root)
sensor_scroll.grid(row=0,column=2,sticky='ns')
sensor_scroll.configure(command=sensor_listbox.yview)
sensor_listbox.configure(yscrollcommand=sensor_scroll.set)
# Add items to the listbox
sensor_list = ["Sentinel-2", "Sentinel-1", "Landsat-8/9","Landsat-7","Landsat-4/5","ASTER (SWIR On)","ASTER (SWIR Off)"]
for item in sensor_list:
sensor_listbox.insert("end",item)
sensor_listbox.select_set(4)
button = tk.Button(root, text="OK", command=confirm_selection)
button.grid(row=3, column=2)#,columnspan=3)
root.mainloop()
I was expecting the listbox to have a scrollbar attached on the right side.
Change this:
sensor_scroll.grid(row=0,column=2,sticky='ns')
to:
sensor_scroll.grid(row=0,column=2,sticky='ne')
Description
I am creating a canvas with scrollbar and adding frames with a text box in the frame and to fill the entire frame with no border. This will make it look as if the frame is the textbox. I have added shadow and styling to the frame (as coded by Bryan). This is added dynamically in for loop.
When I am trying to expand the text box to the frame, it is not expanding to fill the entire frame. There are extra spaces left.
Question
How do I fill up the entire frame with the textbox using a grid?

I'm learning Tkinter at the moment. From my book, I get the following code for producing a simple vertical scrollbar:
from tkinter import * # Import tkinter
class ScrollText:
def __init__(self):
window = Tk() # Create a window
window.title("Scroll Text Demo") # Set title
frame1 = Frame(window)
frame1.pack()
scrollbar = Scrollbar(frame1)
scrollbar.pack(side = RIGHT, fill = Y)
text = Text(frame1, width = 40, height = 10, wrap = WORD,
yscrollcommand = scrollbar.set)
text.pack()
scrollbar.config(command = text.yview)
window.mainloop() # Create an event loop
ScrollText() # Create GUI
which produces the following nice output:
enter image description here
However, when I then try to change this code in the obvious way to get a horizontal scrollbar, it's producing a weird output. Here's the code I'm using
from tkinter import * # Import tkinter
class ScrollText:
def __init__(self):
window = Tk() # Create a window
window.title("Scroll Text Demo") # Set title
frame1 = Frame(window)
frame1.pack()
scrollbar = Scrollbar(frame1)
scrollbar.pack(side = BOTTOM, fill = X)
text = Text(frame1, width = 40, height = 10, wrap = WORD,
xscrollcommand = scrollbar.set)
text.pack()
scrollbar.config(command = text.xview)
window.mainloop() # Create an event loop
ScrollText() # Create GUI
and here's what I get when I run this:
enter image description here
You're assigning horizontal scrolling, xscrollcommand, to a vertical scrollbar. You need to modify Scrollbar's orient option to 'horizontal' which is by default 'vertical'.
Try replacing:
scrollbar = Scrollbar(frame1)
with:
scrollbar = Scrollbar(frame1, orient='horizontal')
I am new to tkinter and python3. I have worked on creating a scrollbar for a frame that is a child of a canvas which is also a child of Toplevel(). The scrollbar buttons function well but the bar/box itself stretches from top to bottom and cannot move. Furthermore, using the scroll buttons, the user can scroll way beyond the content (where there nothing to view).
Here is the code.
#! /usr/bin/env python3
from tkinter import *
from filegroups import typeGroups
app = Tk()
types_window = Toplevel(app)
types_window.wm_title('Types')
yscrollbar = Scrollbar(types_window, orient=VERTICAL)
yscrollbar.grid(row=0, column=1, sticky=N+S)
canvas = Canvas(types_window,
width = 300,
height = 500,
yscrollcommand=yscrollbar.set)
canvas.grid(row=0,column=0)
canvas.config(scrollregion=canvas.bbox("all"))
yscrollbar.config(command=canvas.yview)
frame = Frame(canvas)
canvas.create_window(0,0,anchor=NW,window=frame)
for key in sorted(typeGroups.keys()):
options_frame = LabelFrame(frame, text=key)
options_frame.grid(padx=5, pady=10)
for item in typeGroups[key]:
item_button = Checkbutton(options_frame,
text=item)
item_button.grid()
app.mainloop()
You need to update the canvas scrollregion after filling the frame with labels by adding these two lines just before app.mainloop():
canvas.update_idletasks()
canvas.config(scrollregion=canvas.bbox("all"))
The call to update_idletasks is needed to ensure that the canvas content is updated before we ask for the bounding box.
I've embedded 100 rows in 2 columns. Each row is inside a single frame, and all packed inside a text widget. I'm trying to add a scroll bar, but it scrolls only text, while the columns won't move.
frame_fields = tk.Text(self.window)
frame_fields.pack_propagate(0)
tf = {}
text_labels = tk.Text(frame_fields)
text_labels.pack(side='left', expand='yes', fill='both')
scrollbar = tk.Scrollbar(frame_fields)
scrollbar.config(command=text_labels.yview)
scrollbar.pack(side='right', fill='y')
text_labels.config(yscrollcommand=scrollbar.set)
for f in range(100):
tf[f] = tk.Frame(text_labels)
e_find = tk.Entry(tf[f])
e_replace = tk.Entry(tf[f])
e_find.pack(side='left')
e_replace.pack(side='left')
tf[f].pack()
frame_fields.pack()
How should I change this code, so text_labels scroll?
A Solution
The code below creates the scrollable cells:
def create_cells(self):
"""Create cells for exception text"""
# ----------------------------------------------
frame_fieldsscroll = tk.Text(self.main, relief='flat')
text_fields = tk.Text(frame_fieldsscroll, relief='flat')
frame_fieldsscroll.window_create('insert', window=text_fields)
tf = {}
for f in range(31):
e_find = tk.Entry(text_fields, width=16, relief='flat')
e_replace = tk.Entry(text_fields, width=16, relief='flat')
e_find.insert(0, 'find'+str(f))
e_replace.insert(0, 'replace'+str(f))
e_find.grid(row=0, column=0)
e_replace.grid(row=0, column=1)
text_fields.window_create('insert', window=e_find)
text_fields.window_create('insert', window=e_replace)
text_fields.insert('end', '\n')
scrollbar = tk.Scrollbar(frame_fieldsscroll, width=15)
scrollbar.config(command=text_fields.yview)
text_fields.config(yscrollcommand=scrollbar.set)
frame_fieldsscroll.pack()
scrollbar.pack(side='right', fill='y')
text_fields.pack(fill='both')
text_fields.configure(state='disabled')
frame_fieldsscroll.configure(state='disabled')
For objects in a window to be scrollable along with the text you must add them with the window_create method of the text widget instead of using pack or grid or place.
