How do I float tkinter buttons vertically on the left side - python

I want my tkinter buttons, entry and text to float in the middle vertically, on the left side. I've tried using pack() with side=left, but it just stacked them horizontally, if I could stack them vertically that would be perfect. I've tried using grid, but I can't get them into the middle. I've tried anchor w but that didn't work either. Thanks!
import tkinter as tk
class Fullscreen:
def __init__(self):
self.window = tk.Tk()
self.window.title("Example")
self.fullScreenState = True
self.window.attributes("-fullscreen", self.fullScreenState)
self.w, self.h = self.window.winfo_screenwidth(), self.window.winfo_screenheight()
self.window.geometry("%dx%d" % (self.w, self.h))
self.window.bind("<F11>", self.toggleFullScreen)
self.window.bind("<Escape>", self.quitFullScreen)
def room_button():
room_text = room_key.get()
print(room_text)
def message_button():
message_text = message.get(1.0, tk.END)
handle_text = handle.get()
print(message_text)
print(handle_text)
greeting = tk.Label(text="Welcome")
# Pack displays the Label's text in the window.
greeting.grid(column=1, sticky='w')
display_room = tk.Label(text="Room:")
display_room.grid(column=1, sticky='w')
room_key = tk.Entry()
room_key.grid(column=1, sticky='w')
send_room_key = tk.Button(text="Change Rooms", command=room_button)
send_room_key.grid(column=1, sticky='w')
display_message = tk.Label(text="Message:")
display_message.grid(column=1, sticky='w')
message = tk.Text()
message.grid(column=1, sticky='w')
display_handle = tk.Label(text="Handle (optional):")
display_handle.grid(column=1, sticky='w')
handle = tk.Entry()
handle.grid(column=1, sticky='w')
send_message = tk.Button(text="Send Message", command=message_button)
send_message.grid(column=1, sticky='w')
quit_button = tk.Button(text="Quit", command=self.window.destroy)
quit_button.grid(column=1, sticky='w')
self.window.mainloop()
def toggleFullScreen(self, event):
self.fullScreenState = not self.fullScreenState
self.window.attributes("-fullscreen", self.fullScreenState)
def quitFullScreen(self, event):
self.fullScreenState = False
self.window.attributes("-fullscreen", self.fullScreenState)
if __name__ == '__main__':
app = Fullscreen()

Is this how You want them to be:
from tkinter import Tk, Frame, Label, Entry, Button
root = Tk()
root.geometry('500x400')
widget_frame = Frame(root)
widget_frame.pack(side='left')
Label(widget_frame, text='Enter info below').pack()
entry = Entry(widget_frame)
entry.pack()
Button(widget_frame, text='Submit').pack()
root.mainloop()
You can just use a frame that will be packed to the left and pack widgets inside the frame and they will be on the left side and in the center

You can also use this:
import tkinter as tk
root = tk.Tk()
root.geometry("500x400")
label = tk.Label(root, text="Enter info below")
label.grid(row=1, column=1, pady=(150, 0))
entry = tk.Entry(root)
entry.grid(row=2, column=1)
button = tk.Button(root, text='Submit')
button.grid(row=3, column=1)
root.mainloop()
The pady=(150, 0) tell the grid method that it should leave 150 pixels above the widget empty. This will give you more control over where the widgets are placed.

tkinter: LabelFrame in a separate TopLevel window

My "simple" intention is to create a Dialog - launched by a button - where I have several LabelFrames with their radio button.
I tried with 1 LabelFrame with this simple code the radios appear in the main window, not in the dialogue one !!!! I cannot understand why. Please help.. ty for your attention
Here's the code:
import tkinter as tk
from tkinter import ttk
class PersonEmptyDocsDialog(tk.Toplevel):
def __init__(self, root,personid):
super().__init__(root)
self.personid = personid
self.code = tk.StringVar()
frame1 = ttk.Labelframe(self,text='testo').grid(column=0,row=0,padx=20,pady=20)
ttk.Radiobutton(frame1, text="Option 1", variable=self.code, value="0-0-0").pack()
ttk.Radiobutton(frame1, text="Option 1", variable=self.code, value="0-0-1").pack()
ttk.Radiobutton(frame1, text="Option 1", variable=self.code, value="0-0-2").pack()
self.ok_button = tk.Button(self, text="OK", command=self.on_ok).grid(column=0,row=1)
#self.ok_button.pack()
def on_ok(self, event=None):
self.destroy()
def show(self):
self.wm_deiconify()
self.wait_window()
return self.code.get()
class Example():
def __init__(self, root):
mainframe = ttk.Frame(root).pack(fill="both", expand=True)
self.root = root
ttk.Button(mainframe, text="Get Input", command=self.on_button).pack(padx=8, pady=8)
ttk.Label(mainframe, text="", width=20).pack(side="bottom", fill="both", expand=True)
def on_button(self):
string = PersonEmptyDocsDialog(self.root, 12).show()
print(string)
root = tk.Tk()
root.wm_geometry("400x200")
Example(root)
root.mainloop()
You cannot put in one line. You need to break this into in line 11
frame1 = ttk.Labelframe(self,text='testo')
frame1.grid(column=0,row=0,padx=20,pady=20)
Output:
Output after clicking Get input button:

Python tkinker resitze Canvas

I have an Python3 Tkinter Programm. I have 3 Frames in the Main Window and in one Frame an canvas with scroll Option - now i want resitze the Canvas Area .
Now if i resize it moves the Scroll Bar for Y out the Window and the scrollbar for x works also not as expected (get bigger but slide area don't change)
How i Mange it to resize an Canvas in an grid Layout - The Window must be the same size , the Scrollbas must be updatet and the Canvas Plane must be bigger.
an excerpt from my code:
import tkinter as tk
def menu_build():
caninfo[0] += 10
cangui.configure(width = caninfo[0])
#cangui.configure(scrollregion=cangui.bbox("all"))
def gui():
master = tk.Tk()
master.title( "Easy Switch" )
master.geometry("480x320")
frametop = tk.Frame(master, bg="blue", bd=2)
frametop.grid(column=0,row=0)
frameex = tk.Frame(master, bg="yellow", bd=2)
frameex.grid(column=1,row=1)
framegui = tk.Frame(master, bg="red", bd=2)
framegui.grid(column=0, columnspan=2, row=1)
menu = tk.Menu(master)
master.config(menu=menu)
filemenu = tk.Menu(menu)
menu.add_cascade(label="Config", menu=filemenu)
filemenu.add_command(label="Resize",command=menu_build)
global cangui
cangui = tk.Canvas(framegui, width=385, height=250)
#caninfo = [385,250]
cangui.grid(row=1, column=2)
scroll_x = tk.Scrollbar(framegui, orient="horizontal", command=cangui.xview)
scroll_x.grid(row=2, column=2, sticky="ew")
scroll_y = tk.Scrollbar(framegui, orient="vertical", command=cangui.yview)
scroll_y.grid(row=1, column=3, sticky="ns")
cangui.configure(yscrollcommand=scroll_y.set,xscrollcommand=scroll_x.set)
cangui.configure(scrollregion=cangui.bbox("all"))
cwcb = tk.Checkbutton(framegui, text="ccw").grid(row=2,column=0)
cangui.create_arc(90,90,110,110,style=tk.PIESLICE,width=4,start=0,extent=300)
master.mainloop()
global caninfo
caninfo = [385,250]
if __name__ == "__main__":
gui()
no need to resize the canvas Area
wrote an extra funktion
win = [int(cangui.cget("width")),int(cangui.cget("height"))]
draw_xy = cangui.bbox("all")
swin = (min(0,draw_xy[0]),min(0,draw_xy[1]),max(draw_xy[2],win[0]),max(draw_xy[3],win[1]))
cangui.configure(scrollregion=swin)
reason: canvas.bbox("all") gives only the positon from most upper/left grafic and i want 0/0

How to expand buttons and labels to fill the x axis in python tkinter?

This is a part of code from my school project.

self.info_frame.grid_propagate(0)
root = Tk()
student_window(root)

And it looks something like this.
The Student Panel for my project
The whole window is divided into three frames and want to expand each label and button of the left frame(self.option_frame) to fill it horizontally. I tried doing sticky=EW and sticky=NSEW but still some space is left. How do I fix that?
You need to call self.option_frame.columnconfigure(0, weight=1) to make column 0 to use all the available horizontal space.
I was just trying some things and what I have found to be working is to make the label width bigger than than the frame then anchoring the text to the left.

What is a good way to stop 2 labels in the same row and column from covering each other in tkinter?

When button 1 is pressed I want this program to say word 'hi' and when button 2 is pressed I want it to say 'goodbye' in the same spot as it says hi and override what button 1 produced. However, it doesn't override it just merges the 2 labels together. What is a good way to prevent this from happening while making sure both labels appear in the same spot?
from tkinter import *
root = Tk()
def press():
word = Label(root, text='hi')
word.grid(row=0, column=1)
def press_2():
word_2 = Label(root, text='goodbye')
word_2.grid(row=0, column=1)
button_1 = Button(root, text=1, command=press)
button_2 = Button(root, text=2, command=press_2)
button_1.grid(row=0, column=0)
button_2.grid(row=1, column=0)
root.mainloop()
You just need to use one Label and keep changing its text. We can do this efficiently by using a lambda for the widget command. As stated by #Bryan Oakley, using a StringVar adds unnecessary overhead. This is a slightly modified version from my original. In this version we use the config method of the widget to set the text. As a bonus the code is formatted with a class structure. Using a procedural style with tkinter eventually turns into a big mess. Considering the required imports are minimal, we import them directly and do not need to prefix every widget.
from tkinter import Tk, Button, Label
class Application(Tk):
def __init__(self, *args, **kwargs):
Tk.__init__(self, *args, **kwargs)
lbl = Label(self, text='hi')
lbl.grid(row=0, column=1)
btn1 = Button(self, text='1',)
btn1.config(command=lambda m='hi': lbl.config(text=m))
btn1.grid(row=0, column=0)
btn2 = Button(self, text='2')
btn2.config(command=lambda m='goodbye': lbl.config(text=m))
btn2.grid(row=1, column=0)
if __name__ == "__main__":
app = Application()
app.minsize(100, 50)
app.title("My Application")
app.mainloop()
from tkinter import *
root = Tk()
def press():
label['text'] = "hi"
def press_2():
label['text'] = "goodbye"
label = Label(root)
label.grid(row=0, column=1)
button_1 = Button(root, text=1, command=press)
button_2 = Button(root, text=2, command=press_2)
button_1.grid(row=0, column=0)
button_2.grid(row=1, column=0)
root.mainloop()
Put it on the windows firstly,Then change the text config.
A better way to do so would be by using config() method of widgets. But here i dont know if its gonna help out much. But give it a try
from tkinter import *
root = Tk()
def press():
word.config(text='hi')
def press_2():
word.config(text='goodbye')
button_1 = Button(root, text=1, command=press)
button_2 = Button(root, text=2, command=press_2)
button_1.grid(row=0, column=0)
button_2.grid(row=1, column=0)
word = Label(root, text='') #creating a blank label to edit later on in functions
word.grid(row=0, column=1)
root.mainloop()

How to add multiline text dynamically in tkinter python?

I have created a chat application, in which i use ListBox for showing the chat history. It looks good until I enter a long sting which goes beyond the screen. Is there a way to break the string and show in new line or any other way to show the complete string. I'm new to Tkinter and im not aware of many widgets available.
Here is my sample code
from tkinter import *
class Actions:
def chatUpdate(chat):
chatlist.insert(Actions.chatLast,chat)
Actions.chatLast=Actions.chatLast+1
chatlist.pack( side=LEFT, fill=BOTH)
chatBox.config(command=chatlist.yview)
def callUpdater():
txt=textBox.get()
text_text.set("")
Actions.chatUpdate(txt)
root = Tk()
root.title("Chat App")
frame1 = Frame(root, bd=4)
frame1.pack(side=TOP)
frame2 = Frame(root, bd=4)
frame2.pack(side=TOP)
frame3 = Frame(root, bd=4)
frame3.pack(side=TOP)
# chat box
chatBox = Scrollbar(frame1)
chatBox.pack(side=RIGHT, fill=Y)
chatlist = Listbox(frame1, yscrollcommand = chatBox.set, width=50)
Actions.chatLast=0
Actions.chatUpdate(" ")
# text box
textView = Label(frame2, text="Input: ")
textView.pack(side=LEFT)
text_text = StringVar()
textBox = Entry(frame2, textvariable=text_text, bd=0, width=40, bg="pink")
textBox.pack(side=RIGHT)
# send button
button = Button(frame3, text="Send", fg="black", command=callUpdater)
button.pack(side=TOP)
root.mainloop()
You can replace the Listbox by a Text widget in 'disabled' mode which automatically wraps long lines. You will just need to put the widget back in 'normal' mode each time you insert text:
from tkinter import *
def callUpdater():
text = textBox.get()
textBox.delete(0, 'end')
chat.configure(state='normal')
chat.insert('end', text + '\n')
chat.configure(state='disabled')
root = Tk()
chatBox = Scrollbar(root)
chat = Text(root, wrap='word', state='disabled', width=50,
yscrollcommand=chatBox.set)
chatBox.configure(command=chat.yview)
chat.grid(row=0, columnspan=2, sticky='ewns')
chatBox.grid(row=0, column=2, sticky='ns')
Label(root, text="Input: ").grid(row=1, column=0)
textBox = Entry(root, bd=0, width=40, bg="pink")
textBox.grid(row=1, column=1)
Button(root, text="Send", command=callUpdater).grid(row=2, columnspan=2)
root.mainloop()
By the way, both the Listbox and Text widgets support the index 'end' so you don't have to keep track of how many lines you have inserted.
