I'm creating a program by learning from youtube tutorials (I'm a complete beginner) and I have come to some difficulties. This time, I'm trying to create a scrollbar, and I want my widgets to stay on the center of my window, not the left (I'm following the Codemy.com tutorial on scrollbars).
Here is the current aspect of my program:
with scrollbar
And here is how I want it to look:
without scrollbar
This is my code right now:
import tkinter as tk
root = tk.Tk()
root.geometry("600x400")
my_canvas = tk.Canvas(root)
my_canvas.pack(side = "left", fill = "both", expand = 1)
my_scrollbar = tk.Scrollbar(root, orient = "vertical", command = my_canvas.yview)
my_scrollbar.pack(side = "right", fill = "y")
my_canvas.configure(yscrollcommand = my_scrollbar.set)
my_canvas.bind("<Configure>", lambda e: my_canvas.configure(scrollregion = my_canvas.bbox("all")))
my_frame = tk.Frame(my_canvas)
for i in range(100):
my_label = tk.Label(my_frame, text = "Label")
my_label.pack()
my_canvas.create_window((0,0), window = my_frame, anchor = "nw")
root.mainloop()
Include width = 600, anchor = "nw" in my_canvas declaration.
my_canvas.create_window((0,0), window = my_frame, width = 600, anchor = "nw")
I want to put the horizontal and vertical scrollbars at the edge of the yellow canvas using Python tkinter, but whatever I do, it does not move and just stay inside the perimeter of the canvas. Why? Below is the image:
Below is the code:
def render_gui(self):
self.main_window = tk.Tk()
self.main_window.geometry("1000x600")
self.main_window.title("Damaged Text Document Virtual Restoration")
self.main_window.resizable(True, True)
self.main_window.configure(background="#d9d9d9")
self.main_window.configure(highlightbackground="#d9d9d9")
self.main_window.configure(highlightcolor="black")
self.main_canvas = tk.Canvas(self.main_window, bg = "yellow")
self.main_canvas.pack(expand = True, fill = "both")
vsb = tk.Scrollbar(self.main_canvas, orient="vertical", command=self.main_canvas.yview)
hsb = tk.Scrollbar(self.main_canvas, orient="horizontal", command=self.main_canvas.xview)
vsb.grid(row=1, column=50,columnspan = 20, sticky='ns')
hsb.grid(row=20, column=1,rowspan = 20,sticky = 'wes')
self.main_canvas.configure(yscrollcommand=vsb.set,xscrollcommand=hsb.set)
self.main_window.mainloop()
Please help.
The problem is that you are putting the scrollbars inside the canvas, and you've put nothing else in the canvas.
When you use grid to put something inside another widget, rows and columns that are empty have a size of zero. Thus, even though you put the vertical scrollbar in column 50, columns 0 and 2-49 have a width of zero so column 50 appears on the left. (Column 1 is the width of the horizontal scrollbar.)
The same is true for the horizontal scrollbar - you're putting it in row 20, but rows 0 and 2-19 have a height of zero, so row 20 appears near the top.
Normally it's not a good idea to put scrollbars inside the canvas, since anything you draw on the canvas might be hidden or partially hidden by the scrollbars. If you want them to appear to be in the canvas, the simplest solution is to put both the canvas and the scrollbars inside a frame. You can then turn the border off on the canvas and turn the border on for the frame.
Example:
import tkinter as tk
class Example():
def render_gui(self):
self.main_window = tk.Tk()
self.main_window.geometry("1000x600")
self.main_window.title("Damaged Text Document Virtual Restoration")
self.main_window.resizable(True, True)
self.main_window.configure(background="#d9d9d9")
self.main_window.configure(highlightbackground="#d9d9d9")
self.main_window.configure(highlightcolor="black")
canvas_container = tk.Frame(self.main_window, bd=1, relief='sunken')
canvas_container.pack(expand = True, fill = "both")
self.main_canvas = tk.Canvas(canvas_container, bg = "yellow")
vsb = tk.Scrollbar(canvas_container, orient="vertical", command=self.main_canvas.yview)
hsb = tk.Scrollbar(canvas_container, orient="horizontal", command=self.main_canvas.xview)
self.main_canvas.configure(yscrollcommand=vsb.set,xscrollcommand=hsb.set)
vsb.grid(row=0, column=1, sticky="ns")
hsb.grid(row=1, column=0, sticky="ew")
self.main_canvas.grid(row=0, column=0, sticky="nsew")
canvas_container.grid_rowconfigure(0, weight=1)
canvas_container.grid_columnconfigure(0, weight=1)
self.main_window.mainloop()
e = Example()
e.render_gui()
The code has the canvas as the parent to the scrollbars.
Setting the scrollbars to have the same parent as the canvas, and changing a few placement things around, renders something workable:
import tkinter as tk
class test:
def __init__(self):
self.render_gui()
def render_gui(self):
self.main_window = tk.Tk()
self.main_window.geometry("1000x600")
self.main_window.title("Damaged Text Document Virtual Restoration")
self.main_window.resizable(True, True)
self.main_window.configure(background="#d9d9d9")
self.main_window.configure(highlightbackground="#d9d9d9")
self.main_window.configure(highlightcolor="black")
self.main_canvas = tk.Canvas(self.main_window, bg = "yellow")
vsb = tk.Scrollbar(self.main_window, orient="vertical", command=self.main_canvas.yview)
hsb = tk.Scrollbar(self.main_window, orient="horizontal", command=self.main_canvas.xview)
hsb.pack(side = "bottom", fill = "x")
vsb.pack(side = "right", fill = "y")
self.main_canvas.pack(expand = True, fill = "both")
self.main_canvas.configure(yscrollcommand=vsb.set,xscrollcommand=hsb.set)
self.main_window.mainloop()
t = test()
from tkinter import *
from tkinter import scrolledtext
janela = Tk()
scroll_x = Scrollbar(janela, orient="horizontal")
text = scrolledtext.ScrolledText(janela, wrap=NONE)
text.config(xscrollcommand=scroll_x.set)
scroll_x.configure(command=text.xview)
text.pack(fill=X)
scroll_x.pack(fill=X)
janela.mainloop()
I try to put the widgets like this:
I don't understand why my code doesn't do that, tried to look for examples online but didn't find a solution and nothing I tried brought me closer to the requested result.
This is my code so far(if you have any comments about anything in the code feel free to tell me because it's my first try with tkinter and GUIs in general):
from Tkinter import *
class box(object):
def __init__ (self, colour,s):
self.root = root
self.listbox = Listbox(self.root, fg = colour, bg = 'black')
self.s = s
self.place_scrollbar()
self.listbox.pack(side = self.s)
def place_scrollbar(self):
scrollbar = Scrollbar(self.root)
scrollbar.pack(side = self.s, fill = Y)
self.listbox.config(yscrollcommand = scrollbar.set)
scrollbar.config(command = self.listbox.yview)
def write(self, contenet):
self.listbox.insert(END, contenet)
root = Tk()
root.resizable(False, False)
boxs = Frame(root)
boxs.pack()
box.root = boxs
server = box("red", LEFT)
client = box("green", RIGHT )
bf = Frame(root)
bf.pack(side = BOTTOM)
entry = Entry(bf,bg ='black', fg = 'white')
entry.pack()
root.mainloop()
You can't do this without using an additional frame to contain the box objects while still using pack, while still maintaining resizability.
But it is more organized in some cases to: use an additional frame to contain your box objects, by initializing it with a parent option.
Right now the widgets inside the box class are children to global root object. Which isn't really a good practice. So let's first pass and use a parent object to be used for widgets inside.
Replace:
def __init__ (self, colour,s):
self.root = root
self.listbox = Listbox(self.root, ...)
...
def place_scrollbar(self):
scrollbar = Scrollbar(self.root)
...
with:
def __init__ (self, parent, colour,s):
self.parent= parent
self.listbox = Listbox(self.parent, ...)
...
def place_scrollbar(self):
scrollbar = Scrollbar(self.parent)
...
This makes it so that you now need to initialize the object like the following:
server = box(root, "red", LEFT)
client = box(root, "green", RIGHT )
Now that we can pass a parent widget, let's create a parent frame to contain them. Actually, there's an un-used frame already, boxs let's use that by passing it as the parent as opposed to root:
server = box(boxs, "red", LEFT)
client = box(boxs, "green", RIGHT )
Now everything looks fine, optionally if you want to make it so that entry occupies as much left space as possible currently add fill='x' as an option to the pack of both the entry and the frame that contains it:
bf.pack(side = BOTTOM, fill='x')
...
entry.pack(fill='x')
Your whole code should look like:
from Tkinter import *
class box(object):
def __init__ (self, parent, colour,s):
self.parent = parent
self.listbox = Listbox(self.parent, fg = colour, bg = 'black')
self.s = s
self.place_scrollbar()
self.listbox.pack(side = self.s)
def place_scrollbar(self):
scrollbar = Scrollbar(self.parent)
scrollbar.pack(side = self.s, fill = Y)
self.listbox.config(yscrollcommand = scrollbar.set)
scrollbar.config(command = self.listbox.yview)
def write(self, contenet):
self.listbox.insert(END, contenet)
root = Tk()
root.resizable(False, False)
boxs = Frame(root)
boxs.pack()
box.root = boxs
server = box(boxs, "red", LEFT)
client = box(boxs, "green", RIGHT )
bf = Frame(root)
bf.pack(side = BOTTOM, fill='x')
entry = Entry(bf,bg ='black', fg = 'white')
entry.pack(fill='x')
root.mainloop()
Or: use grid instead of pack (with columnspan=2 option for entry).
General Answer
More generally putting a widget beneath two widgets that are side-by-side can be done by:
Encapsulating the side-by-side widgets with a frame, and then simply putting the frame above the other widget:
try: # In order to be able to import tkinter for
import tkinter as tk # either in python 2 or in python 3
except ImportError:
import Tkinter as tk
def main():
root = tk.Tk()
side_by_side_widgets = dict()
the_widget_beneath = tk.Entry(root)
frame = tk.Frame(root)
for name in {"side b", "y side"}:
side_by_side_widgets[name] = tk.Label(frame, text=name)
side_by_side_widgets[name].pack(side='left', expand=True)
frame.pack(fill='x')
the_widget_beneath.pack()
root.mainloop()
if __name__ == '__main__':
main()
Using grid:
try: # In order to be able to import tkinter for
import tkinter as tk # either in python 2 or in python 3
except ImportError:
import Tkinter as tk
def main():
root = tk.Tk()
side_by_side_widgets = dict()
the_widget_beneath = tk.Entry(root)
for index, value in enumerate({"side b", "y side"}):
side_by_side_widgets[value] = tk.Label(root, text=value)
side_by_side_widgets[value].grid(row=0, column=index)
the_widget_beneath.grid(row=1, column=0, columnspan=2)
root.mainloop()
if __name__ == '__main__':
main()
Without using additional frames, by calling pack for the_widget_beneath with side='bottom' as the first pack call, as in Bryan's comment:
try: # In order to be able to import tkinter for
import tkinter as tk # either in python 2 or in python 3
except ImportError:
import Tkinter as tk
def main():
root = tk.Tk()
side_by_side_widgets = dict()
the_widget_beneath = tk.Entry(root)
the_widget_beneath.pack(side='bottom')
for name in {"side b", "y side"}:
side_by_side_widgets[name] = tk.Label(root, text=name)
side_by_side_widgets[name].pack(side='left', expand=True)
root.mainloop()
if __name__ == '__main__':
main()
You can more easily notice reliability to global objects by creating a global main method, and add main-body of your script there and call:
...
def main():
root = Tk()
root.resizable(False, False)
boxs = Frame(root)
boxs.pack()
box.root = boxs
server = box(boxs, "red", LEFT)
client = box(boxs, "green", RIGHT )
bf = Frame(root)
bf.pack(side = BOTTOM, fill='x')
entry = Entry(bf,bg ='black', fg = 'white')
entry.pack(fill='x')
root.mainloop()
if __name__ == '__main__':
main()
How to put a widget beneath two widgets that are side-by-side using pack?
For a very simple layout like in your diagram, you simply need to pack the thing on the bottom first. That is because pack uses a "cavity" model. Each widget is organized in an unfilled cavity. Once that widget has been placed, that portion of the cavity is filled, and is unavailable for any other widgets.
In your case, you want the bottom cavity to be filled with the entry widget, so you should pack it first. Then, in the remaining upper cavity you can place your two frames side-by side, one on the left and one on the right.
For example:
import Tkinter as tk
root = tk.Tk()
entry = tk.Entry(root)
frame1 = tk.Frame(root, width=100, height=100, background="red")
frame2 = tk.Frame(root, width=100, height=100, background="green")
entry.pack(side="bottom", fill="x")
frame1.pack(side="left", fill="both", expand=True)
frame2.pack(side="right", fill="both", expand=True)
root.mainloop()
In the body of your question things get a bit more complicated, as you don't just have three widgets like your title suggests, you have several, with some being packed in the root and some being packed elsewhere, with pack statements scattered everywhere.
When using pack, it's best to group widgets into vertical or horizontal slices, and not mix top/bottom with left/right within the same group. It almost seems like you're trying to do that with your boxes, but then you don't -- your "box" is actually two widgets.
Bottom line: be organized. It also really, really helps if all of your pack (or place or grid) statements for a given parent are all in the same block of code. When you scatter them around it makes it impossible to visualize, and impossible to fix. Also, make sure that widgets have the appropriate parents.
I am using Tix to automatically create a scroll bar as the content changes. I want to keep a button or two in the user's view while they scroll through the contents of the application.
I haven't seen this question for Tkinter/Tix yet so I thought I'd ask.
The following code will create a sample of the problem where the button is at a fixed point in the window, and is subject to being scrolled.
from Tkinter import *
import Tix
class some_GUI:
def __init__(self, root):
sw= Tix.ScrolledWindow(root, scrollbar=Tix.AUTO)
sw.pack(fill=Tix.BOTH, expand=1)
frame1 = Frame(sw.window)
frame1.grid(row = 0, column = 1)
frame2 = Frame(sw.window)
frame2.grid(row = 0, column = 2)
def quit():
root.quit()
for i in range(0,300):
label1 = Label(frame1, text = "foo")
label1.grid(row = i, column = 0)
button = Button(frame2, text = "Quit", command = quit)
button.pack()
root = Tix.Tk()
display = some_GUI(root)
root.mainloop()
I want the button(s) to be in "frame2" and centered vertically relative to the application's window. I tried using winfo_height/winfo_width to find the frame's height/ width to work with update, but these values didn't change with the addition of the labels and button.
Attempted/possible solutions:
I put frame2 in sw.subwidgets_all[1] by doing the following:
frame1.pack(side = LEFT)
frame2 = Frame(sw.subwidgets_all()[1])
frame2.pack(side = RIGHT)
button = Button(frame2, text = "Quit", command = quit)
button.pack(side = RIGHT)
This allows the fixed position relative to the application, but the window resizes relative to the button's parent instead of frame1. Another drawback is that the horizontal scrollbar is only relative to frame1.
Find the midpoint of the scrollbar and update the position of the buttons relative to those coordinates using place(maybe?) not sure how to accomplish this, and seeing SO solutions in general I think this might be an inefficient way of doing this.
EDIT: Although this isn't exactly what I had in mind, the following code works as per falsetru's suggestion in the comments:
from Tkinter import *
import Tix
class some_GUI:
def __init__(self, root):
def quit():
root.quit()
frame2 = Frame(root)
frame2.pack(side = RIGHT)
button = Button(frame2, text = "Quit", command = quit)
button.pack()
frame1 = Frame(root)
frame1.pack(side = LEFT)
sw= Tix.ScrolledWindow(frame1, scrollbar=Tix.AUTO)
sw.pack(fill=Tix.BOTH, expand=1)
for widget in sw.subwidgets_all():
print widget
for i in range(0,300):
label1 = Label(sw.window, text = "foo")
label1.grid(row = i, column = i)
print root.winfo_toplevel()
for widget in sw.subwidgets_all():
print widget
root = Tix.Tk()
display = some_GUI(root)
root.mainloop()
You can put the button out of ScrollWindows:
import Tix
from Tkinter import *
def build_ui(root):
sw = Tix.ScrolledWindow(root, scrollbar=Tix.AUTO)
sw.pack(side=LEFT, fill=Tix.BOTH, expand=1)
for i in range(300):
label1 = Label(sw.window, text="foo")
label1.grid(row=i, column=0)
button = Button(root, text="Quit", command=root.quit)
button.pack(side=RIGHT)
root = Tix.Tk()
build_ui(root)
root.mainloop()
The second option you mentioned could be the one that satisfies your situation, however that is computationally expensive as you will need to delete the button(s) and redraw them over and over relatively to the scrollbar up/down motion. Not only this is ugly by design but it can be an obstacle for any further scalability of your application or even lead to unexpected bugs if your application runs some serious operations.
The only realistic solution I see for your problem is to fix the button(s) on (for example the bottom of) the upper canvas (or whatever region you want to set) and outside the scrollable region as #falsetru commented you.
Is there a way to add a scrollbar to my entire window without putting everything into a frame? I've set everything up with .grid, and I don't like the idea of wrapping a frame around everything.
root = Tk()
root.maxsize(900,600)

How to add scrollbars to full window in tkinter ?
here is the answer for python 3...
from tkinter import *
from tkinter import ttk
root = Tk()
root.title('Full Window Scrolling X Y Scrollbar Example')
root.geometry("1350x400")
# Create A Main frame
main_frame = Frame(root)
main_frame.pack(fill=BOTH,expand=1)
# Create Frame for X Scrollbar
sec = Frame(main_frame)
sec.pack(fill=X,side=BOTTOM)
# Create A Canvas
my_canvas = Canvas(main_frame)
my_canvas.pack(side=LEFT,fill=BOTH,expand=1)
# Add A Scrollbars to Canvas
x_scrollbar = ttk.Scrollbar(sec,orient=HORIZONTAL,command=my_canvas.xview)
x_scrollbar.pack(side=BOTTOM,fill=X)
y_scrollbar = ttk.Scrollbar(main_frame,orient=VERTICAL,command=my_canvas.yview)
y_scrollbar.pack(side=RIGHT,fill=Y)
# Configure the canvas
my_canvas.configure(xscrollcommand=x_scrollbar.set)
my_canvas.configure(yscrollcommand=y_scrollbar.set)
my_canvas.bind("<Configure>",lambda e: my_canvas.config(scrollregion= my_canvas.bbox(ALL)))
# Create Another Frame INSIDE the Canvas
second_frame = Frame(my_canvas)
# Add that New Frame a Window In The Canvas
my_canvas.create_window((0,0),window= second_frame, anchor="nw")
for thing in range(100):
Button(second_frame ,text=f"Button {thing}").grid(row=5,column=thing,pady=10,padx=10)
for thing in range(100):
Button(second_frame ,text=f"Button {thing}").grid(row=thing,column=5,pady=10,padx=10)
root.mainloop()
you might be able to set a scrollbarr to root.
scrollderoot = tkinter.Scrollbar(orient="vertical", command=root.yview)
scrollderoot.grid(column=5, row=0, sticky='ns', in_=root) #instead of number 5, set the column as the expected one for the scrollbar. Sticky ns will might be neccesary.
root.configure(yscrollcommand=scrollderoot.set)
Honestly i didn't tried this but "should" work. Good luck.
This approach uses no Frame objects and is different in that it creates a very large Canvas with Scrollbars and asks you for an image to display on it.
The screen is then set with self.root.wm_attributes("-fullscreen", 1)
and self.root.wm_attributes("-top", 1)

From the great effbot docs:
In Tkinter, the scrollbar is a separate widget that can be attached to
any widget that support the standard scrollbar interface. Such widgets
include:
the Listbox widget.
the Text widget.
the Canvas widget
the Entry widget
So, you cannot directly use a scrollbar in a Frame. It may be possible to create your own Frame sub-class that supports the scrollbar interface.
Out of the 4 widgets listed above, only one allows other widgets within it: the Canvas. You can use a Canvas to have scrollable content, but placing widgets within a Canvas does not use pack or grid, but uses explicit pixel locations (i.e. painting on the Canvas).
Here's a class, and some example usage, that uses the .place method to add a scrollbar for the whole window. You can create a Frame object, and place it at your desired (x, y) coordinates. Then, simply pass your Frame object in place of root in main.frame to create a scrollable window at your desired coordinates.
