I'm making a table, and the grid of the table is going to be filled with buttons, Is it possible to fit more than one button in a grid space?
Yes you can. Put a frame inside the cell, and then you can put whatever you want inside the frame. Inside the frame you can use pack, place or grid since it is independent from the rest of the widgets.
For example:
import Tkinter as tk
root = tk.Tk()
l1 = tk.Label(root, text="hello")
l2 = tk.Label(root, text="world")
f1 = tk.Frame(root)
b1 = tk.Button(f1, text="One button")
b2 = tk.Button(f1, text="Another button")
l1.grid(row=0, column=0)
l2.grid(row=0, column=1)
f1.grid(row=1, column=1, sticky="nsew")
b1.pack(side="top")
b2.pack(side="top")
root.mainloop()
#jasonharper already provided the answer, but here's some code to go along with it.
This is just a random example with a bunch of buttons / frames using grid / pack. The pack for the buttons was arbitrary you could have used grid instead Each grid section has a random padx to show that it's in a different column and each different column within the grid contains multiple buttons
import tkinter as tk
root = tk.Tk()
#Now you want another frame
for i in range(5):
gridframe = tk.Frame(root)
for j in range(3):
tk.Button(gridframe, text="%d%d" % (i, j)).pack(side=tk.LEFT)
gridframe.grid(row=0, column=i, padx=20)
root.mainloop()

I am trying to make a game using python 3.8, where I have 1 canvas/frame and 2 buttons. I want the buttons to be right next to each other but whenever I run the code, there is always white space in between the 2 buttons. I tried using pack() but when you click on the buttons, it makes the buttons go above the canvas/frame instead of to the right of it.
My code:
from tkinter import *
# windows, canvas, and frames
root = Tk()
WatchRun = Canvas(root, bg="green", width=600, height=500)
WatchRun.grid(row=0, column=0, rowspan=25)
Upgrade = Frame(root, bg="yellow", width=600, height=500)
Upgrade.grid_forget()
# button functions
def show_upgrade(widget, widget2):
global upgradeBtn
global WatchRunBtn
widget.grid_forget()
widget2.grid(row=0, column=0, rowspan=25)
def show_watchrun(widget, widget2):
global upgradeBtn
global WatchRunBtn
widget.grid_forget()
widget2.grid(row=0, column=0, rowspan=25)
# variables and buttons
distance = 0
started = 0
money = 0
startImage = PhotoImage(file='start.png')
stopImage = PhotoImage(file='stop.png')
upgradeBtn = Button(root, text="Upgrades", width=9, command=lambda: show_upgrade(WatchRun, Upgrade))
upgradeBtn.grid(row=0, column=1)
WatchRunBtn = Button(root, text="Watch run", width=9, command=lambda: show_watchrun(Upgrade, WatchRun))
WatchRunBtn.grid(row=1, column=1)
#loop
root.mainloop()
It appears you're trying to use rowspan to try to force the widgets apart. That's not a good solution.
While there are multiple ways to solve the problem of the buttons not being together, the one I recommend in this specific case is to treat your GUI as if it had three rows (or maybe four, depending on what you want to happen when you resize the window).
Row 0 holds the first button, row 1 holds the second, and row 2 takes up the rest of the GUI. Then, the canvas can span all three rows.
So, start by adding a non-zero weight to the third row so that all unallocated space goes to it.
root.grid_rowconfigure(2, weight=1)
Next, add your buttons to rows 0 and 1:
upgradeBtn.grid(row=0, column=1)
WatchRunBtn.grid(row=1, column=1)
And finally, have your canvas span all three rows. It will force the window to grow larger, with all extra space being given to the third row. This allows the first two rows to retain their natural small height.
WatchRun.grid(row=0, column=0, rowspan=3)
An arguably better solution involves using pack and an extra frame or two. The UI seems to clearly have two logical sections to it: a canvas on the left and a column of buttons on the right. So, you can create one frame for the left and one for the right. Then, put the buttons in the right frame and the canvas in the left frame.
See my comments that indicates the changes in the code. If you have questions left on it, let me know. You may find this Q&A helpfull as well. PEP 8
import tkinter as tk #no wildcard imports
#free functions under imports to ensure function is defined
def show_frame(widget, widget2):
'''common function for upgrade_btn and watchrun_btn
- packs the appropiated widget in the left_frame'''
widget.pack_forget()
widget2.pack()
distance = 0
started = 0
money = 0
#variable names lowercase
root = tk.Tk()
#split window in two containers/master/frames
left_frame = tk.Frame(root)
right_frame= tk.Frame(root)
#leftframe content
watchrun = tk.Canvas(left_frame, bg="green", width=600, height=500)
upgrade = tk.Frame(left_frame, bg="yellow", width=600, height=500)
#rightframe content
upgrade_btn = tk.Button(right_frame, text="Upgrades", width=9, command=lambda: show_frame(watchrun, upgrade))
watchrun_btn = tk.Button(right_frame, text="Watch run", width=9, command=lambda: show_frame(upgrade, watchrun))
#geometry management
left_frame.pack(side=tk.LEFT)
right_frame.pack(side=tk.RIGHT,fill=tk.Y)
watchrun.pack()
upgrade_btn.pack()
watchrun_btn.pack()

I have been making some gui applications using python tkinter.In tkinter pack and grid cannot be used together.While writing a code I had to use pack and then I needed to use 2 features called 'Cloumn' and 'row' of grid but that is impossible.
from tkinter import *
root = Tk()
button = Button(root, text="Click Me")
button.pack(side="bottom") #But I want to put that button in row=3
root.mainloop()
I need to put that button in row number 3.But how can I do it?
Is there any way to do so?
In order for pack and grid to be used in the same code you need to make sure you use them on separate containers. Each container (root window, toplevel window, frame) can only have either grid() or pack().
For example if I need to use pack on a frame and then use grid inside of that frame that is ok. But I cannot use pack inside the frame and also grid inside the frame.
If you expand the window made from the below code you will see how pack and grid can work together if used properly.
import tkinter as tk
root = tk.Tk()
top_frame = tk.Frame(root)
top_frame.pack(sid="top")
bot_frame = tk.Frame(root)
bot_frame.pack(sid="bottom")
tk.Label(top_frame, text="Row 0 of top_frame").grid(row=0, column=0)
tk.Label(bot_frame, text="Row 0 of bot_frame").grid(row=0, column=0)
tk.Label(bot_frame, text="Row 1 of bot_frame").grid(row=1, column=0)
tk.Label(bot_frame, text="Row 2 of bot_frame").grid(row=2, column=0)
tk.Button(bot_frame, text="Row 3 of bot_frame").grid(row=3, column=0)
root.mainloop()
I started with the GUI in Python and have a problem.
I've added widgets to my frame, but they're always on the left side.
I have tried some examples from the internet, but I did not manage it .
I tried .place, but it does not work for me. Can one show me how to place the widgets in the middle?
Code:
import tkinter as tk
def site_open(frame):
frame.tkraise()
window = tk.Tk()
window.title('Test')
window.geometry('500x300')
StartPage = tk.Frame(window)
FirstPage = tk.Frame(window)
for frame in (StartPage, FirstPage):
frame.grid(row=0, column=0, sticky='news')
lab = tk.Label(StartPage, text='Welcome to the Assistant').pack()
lab1 = tk.Label(StartPage, text='\n We show you helpful information about you').pack()
lab2 = tk.Label(StartPage, text='\n \n Name:').pack()
ent = tk.Entry(StartPage).pack()
but = tk.Button(StartPage, text='Press', command=lambda:site_open(FirstPage)).pack()
lab1 = tk.Label(FirstPage, text='1Page').pack()
but1 = tk.Button(FirstPage, text='Press', command=lambda:site_open(StartPage)).pack()
site_open(StartPage)
window.mainloop()
After you have created window, add:
window.columnconfigure(0, weight=1)
More at The Grid Geometry Manager
You are mixing two different Layout Managers. I suggest you either use The Grid Geometry Manager or The Pack Geometry Manager.
Once you have decided which one you would like to use, it is easier to help you :)
For example you could use the Grid Geometry Manager with two rows and two columns and place the widgets like so:
label1 = Label(start_page, text='Welcome to the Assistant')
# we place the label in the page as the fist element on the very left
# and allow it to span over two columns
label1.grid(row=0, column=0, sticky='w', columnspan=2)
button1 = Button(start_page, text='Button1', command=self.button_clicked)
button1.grid(row=1, column=0)
button2 = Button(start_page, text='Button2', command=self.button_clicked)
button2.grid(row=1, column=1)
This will lead to having the label in the first row and below the two buttons next to each other.
I have a frame in PanedWindow which i need on every tkinter GUI (in this case it's topFrame). Below it are many frames and I want to switch between those frame on button click (just like in any software where the top portion of screen is fixed and clicking on buttons the lower portion of GUI changes).
I know i need grid layout for it. But, it is not happening and i am not getting a solution anywhere.I have researched a lot on this topic everywhere but this solution is nowhere. Here is my code... i have written in comments those code which i feel are not working fine.
#python 3.5
from tkinter import *
#function to raise the frame on button click
def raiseFrame(frame):
frame.tkraise()
m = PanedWindow(height=500, width=1000, orient=VERTICAL)
m.pack(fill=BOTH, expand=1)
#to expand the column and row to fill the extra space
m.grid_columnconfigure(index=0, weight=1) #this code is not working as it should
m.grid_rowconfigure(index=0, weight=1) #this code is not working as it should
#top frame has two buttons which switches the bottom frames
topFrame = Frame(m, bg="blue")
m.add(topFrame)
button1 = Button(topFrame, text="Raise Frame 2", command=lambda: raiseFrame(frame2)) #raises frame 2 on clicking it
button1.pack(side=LEFT)
button2 = Button(topFrame, text="Raise Frame 1", command=lambda: raiseFrame(frame1)) #raises frame 1 on clicking it
button2.pack(side=LEFT)
#bottomframe acts as container for two other frames which i need to switch
bottomframe = Frame(m, bg="orange")
m.add(bottomframe)
frame1 = Frame(bottomframe, bg="yellow")
frame1.grid(row=0, column=0, sticky="news") ## sticky is not working ##
frame2 = Frame(bottomframe, bg="green")
frame2.grid(row=0, column=0, sticky="news") ## sticky is not working ##
label1 = Label(frame1, text="i should change")
label1.pack(padx=10, pady=10)
label2 = Label(frame2, text="i am changed !!")
label2.pack(padx=10, pady=10)
mainloop()
1)Please correct my code.
2)Explain me why in the "topFrame" even though i have not written
topFrame.pack(fill=BOTH, expand=True)
my code is showing the above property and it's expanding as well as filling both X and Y.
Same goes for the bottomFrame, it's orange colour is filling the entire space which does not happen in normal frames. So, is it some special feature of PanedWindow ?
You don't want to call topFrame.pack() and m.add(topFrame). You either pack/place/grid the window, or you add it to a paned window, you don't do both.
Also, if the frame is going to be in the paned window it needs to be a child of the paned window rather than a child of the root window.
I wrote a collapsible frame widget and was hoping to give it a dock/undock property. From what I've read, widgets can't be placed "over" other widgets (except on canvases, which I wish to avoid) so I can't just "lift" the frame, and their master cannot be changed so I can't simply place the frame into a new Toplevel. The only other option I can think of is to copy the widget into the new Toplevel. Unfortunately, I don't see any options on the copy or deepcopy operations to change the Master before the new widget is created.
So, the question:
Are these assumptions accurate, or is there a way to do any of these things?
If not, do I have any other options than the solution I put together here:
def copywidget(self, frame1, frame2):
for child in frame1.winfo_children():
newwidget = getattr(tkinter,child.winfo_class())(frame2)
for key in child.keys(): newwidget[key] = child.cget(key)
if child.winfo_manager() == 'pack':
newwidget.pack()
for key in child.pack_info():
newwidget.pack_info()[key] = child.pack_info()[key]
elif child.winfo_manager() == 'grid':
newwidget.grid()
for key in child.grid_info():
newwidget.grid_info()[key] = child.grid_info()[key]
elif child.winfo_manager() == 'place':
newwidget.place()
for key in child.place_info():
newwidget.place_info()[key] = child.place_info()[key]
There is no way to reparent a widget to a different toplevel. The easiest thing is to make a method that recreates the widgets in a new parent.
Widgets can be stacked on top of each other, though it requires care. You can, for instance, use grid to place two widgets in the same cell, and you can use place to put one widget on top of another .
Using this answer you are able to copy one widget onto another master. Then, you simply forget the previous widget, and it will work as a moved widget.
Example code:
root = tk.Tk()
frame1 = tk.Frame(root, bg='blue', width=200, height=100)
frame1.grid(row=0, column=0, pady=(0, 5))
frame_to_clone = tk.Frame(frame1)
frame_to_clone.place(x=10, y= 15)
tk.Label(frame_to_clone, text='test text').grid(row=0, column=0)
frame2 = tk.Frame(root, bg='green', width=80, height=180)
frame2.grid(row=1, column=0, pady=(0, 5))
# Move frame_to_clone from frame1 to frame2
cloned_frame = clone_widget(frame_to_clone, frame2)
cloned_frame.place(x=10, y=15)
# frame_to_clone.destroy() # Optional destroy or forget of the original widget
root.mainloop()
