Could anyone share with me how to print the text of the text widget added to a Canvas object? In the code below, I want the system return the value of "hello" when mouse on the text, however, it turns out giving me "1". Don't know why. Could anyone help me?
Many many thanks!!!
import tkinter
from tkinter import *
def show_text(event):
print (canvas.text)
master = tkinter.Tk()
canvas = tkinter.Canvas(master, width = 200, height = 100)
canvas.pack()
canvas.bind('<Enter>',show_text)
canvas.text = canvas.create_text(20, 30, text="hello")
mainloop()
According to the canvas docs:
You can display one or more lines of text on a canvas C by creating a
text object:
id = C.create_text(x, y, option, ...)
This returns the object ID of the text object on canvas C.
Now, you gotta modify the code something like this:
import tkinter
from tkinter import *
def show_text(event):
print (canvas.itemcget(obj_id, 'text'))
master = tkinter.Tk()
canvas = tkinter.Canvas(master, width = 200, height = 100)
canvas.pack()
canvas.bind('<Enter>',show_text)
obj_id = canvas.create_text(20, 30, text="hello")
mainloop()
Follow up (see the documentation for Label.config:
import tkinter
from tkinter import *
from tkinter import ttk
def show_text(event):
print (canvas.itemcget(canvas.text, 'text'))
#The command of writing text 'hello' in sch_Label to replace the text 'the info shows here'
sch_Label.config(text = 'hello!')
master = tkinter.Tk()
canvas = tkinter.Canvas(master, width = 200, height = 100)
canvas.pack()
canvas.bind('<Enter>',show_text)
canvas.text = canvas.create_text(20, 30, text="hello")
pad1 = ttk.Notebook(master)
pad1.pack(side=RIGHT, expand=1, fill="both")
tab1 = Frame(pad1)
pad1.add(tab1, text = "Schedule")
pad1.pack(side=RIGHT)
sch_Label = ttk.Label(tab1, text='The info shows here')
sch_Label.pack(side="top", anchor="w")
mainloop()

I have a sequence of pop up windows. I intended to close the window once i have completed the desired task. I am using a "askokcancel" button to get users confirmation whether the activity has completed. The problem is, every time the user presses ok, the focus goes back to the main starting window and rest of the pop up windows goes to the background while staying active. I want to either close the pop up windows or keep the focus to the second last window. Below is my code:
import tkinter as tk
from tkinter import ttk, StringVar, messagebox
from tkinter.filedialog import askopenfilename
from mytest import *
from tkinter import *
class myclass:
def __init__(self, master):
self.master = master
self.frame1 = tk.Frame(self.master)
self.button1 = tk.Button(self.frame1, text = 'select me first', width = 25, command = self.buttonFunc)
self.button1.pack()
self.quitButton = tk.Button(self.frame1, text = 'Quit', width = 25, command = self.close_windows1)
self.quitButton.pack()
self.frame1.pack()
self.master.geometry("200x200+60+60")
def buttonFunc(self):
self.top = tk.Toplevel(self.master)
self.button2 = tk.Button(self.top,text="Select second",command=self.anotherButtonFunc)
self.button2.pack()
self.quitButton = tk.Button(self.top, text = 'Quit', width = 25, command = self.close_windows2)
self.quitButton.pack()
self.master.geometry("200x200+60+60")
def anotherButtonFunc(self):
self.top2 = tk.Toplevel(self.top)
self.newClass = myClassExt(self.top2)
def close_windows1(self):
self.master.destroy()
def close_windows2(self):
self.top.destroy()
class myClassExt():
def __init__(self, top2):
self.top3 = top2
self.frame2 = tk.Frame(self.top3)
self.button3 = tk.Button(self.frame2, text = 'select me third', width = 25, command = self.buttonFunc)
self.button3.pack()
self.quitButton = tk.Button(self.frame2, text = 'Quit', width = 25, command = self.close_windows4)
self.quitButton.pack()
self.frame2.pack()
self.top3.geometry("200x200+60+60")
def buttonFunc(self):
ok = messagebox.askokcancel(message='Press OK to Confirm?')
if not ok:
pass
else:
messagebox.showinfo("Success","Well done")
self.close_windows4()
def close_windows4(self):
self.top3.destroy()
if __name__ == "__main__":
root = tk.Tk()
myclass = myclass(root)
root.mainloop()
From this made up example, i somehow want to either close window number 2 after user presses OK or keep the focus on window 2 rather than window 1. Please guide
There is no way to close a message box, although you can easily make your own. You just have to make a new tkinter window, and set an image, title, and text, then add a close button, and return the tk window. I made a function like this myself, for this very reason. Here is the function:
def mymessage(title, text, spacing = 25, buttonText = "Close", image = None):
tk2 = Tk()
tk2.resizable(0, 0)
tk2.title(title)
if image != None:
image = Label(tk2, image = PhotoImage(file = image))
image.pack()
spacer = Frame(tk2, relief = FLAT, bd = 0, width = 200, height = 25)
spacer.pack()
label = Label(tk2, text = text)
label.pack()
button = Button(tk2, text = buttonText, width = 5, height = 1, command = tk2.destroy)
button.pack()
return tk2
After calling the function, it returns the tk window, for easy destruction.
I am having this issue where the scroll bar is not displaying on the listbox. I do not know what the issue is as.
I believe the issue is originating from the Scrollbar variables as the Listbox appears to be displaying and functioning properly.
The output is displaying the listbox with no scrollbar on the right (as set)
Here is the Listbox with the for loop however, it is displaying the wrong dimensions
Here is the code:
#imports
from tkinter import *
from tkinter import messagebox as ms
from tkinter import ttk
import sqlite3
from PIL import Image,ImageTk
import datetime
global time
time = datetime.datetime.now()
class main:
def __init__(self,master):
self.master = master
def search_user_sql(self):
self.search_user_sqlf = Frame(self.master, height=300, width =200)
scrollbar = Scrollbar(self.search_user_sqlf)
scrollbar.pack(side = RIGHT,fill = BOTH)
myList = Listbox(self.search_user_sqlf, yscrollcommand= scrollbar.set)
myList.pack( side = LEFT, fill = BOTH, expand = 2)
scrollbar.config( command = myList.yview )
self.search_user_sql()
root = Tk()
root.title("Gym Membership System")
main(root)
root.mainloop()
You need to pack the frame to display it. To pack() the frame with the correct size settings, try:
search_user_sqlf = Frame(master, height=300, width=200)
search_user_sqlf.pack(expand=True, fill='both')
search_user_sqlf.pack_propagate(0)
Here is how to attach a scrollbar to list set in a frame in Tkinter:
from tkinter import *
master = Tk()
search_user_sqlf = Frame( master, width=400, height=400)
search_user_sqlf.pack(expand=True, fill='both')
search_user_sqlf.pack_propagate(0)
scrollbar = Scrollbar(search_user_sqlf)
scrollbar.pack(side=RIGHT, fill=Y)
myList = Listbox(search_user_sqlf, yscrollcommand=scrollbar.set)
for line in range(100):
myList.insert(END, "This is line number " + str(line))
myList.pack( side = LEFT, fill = BOTH , expand = 2)
scrollbar.config( command = myList.yview )
mainloop()
from tkinter import *
import random
root = Tk()
frame1 = Frame(root, width = 400, height = 600)
greet = Label(random.choice(("Hi", "Hello")))
frame1.pack(side=TOP)
greet.pack()
So Actually I want something like this When I Run it should print a label because it can't print like a variable so I tried it. Is there Any other way of printing it in the Tkinter window as label?
You need to assign the string to print to the text property of the label
from tkinter import *
import random
root = Tk()
frame1 = Frame(root, width = 400, height = 600)
greet = Label(text=random.choice(("Hi", "Hello")))
frame1.pack(side=TOP)
greet.pack()
root.mainloop()
I need help about this program, this program should open image in new tkinter window by clicking on button, but it doesn't it just opens new window without image.
Where is the problem?
Using: python 3.3 and tkinter
This is program:
import sys
from tkinter import *
def button1():
novi = Toplevel()
canvas = Canvas(novi, width = 300, height = 200)
canvas.pack(expand = YES, fill = BOTH)
gif1 = PhotoImage(file = 'image.gif')
canvas.create_image(50, 10, visual = gif1, anchor = NW)
mGui = Tk()
button1 = Button(mGui,text ='Sklop',command = button1, height=5, width=20).pack()
mGui.mainloop()
create_image needs a image argument, not visual to use the image, so instead of visual = gif1, you need image = gif1. The next problem is that you need to store the gif1 reference somewhere or else it'll get garbage collected and tkinter won't be able to use it anymore.
So something like this:
import sys
from tkinter import * #or Tkinter if you're on Python2.7
def button1():
novi = Toplevel()
canvas = Canvas(novi, width = 300, height = 200)
canvas.pack(expand = YES, fill = BOTH)
gif1 = PhotoImage(file = 'image.gif')
#image not visual
canvas.create_image(50, 10, image = gif1, anchor = NW)
#assigned the gif1 to the canvas object
canvas.gif1 = gif1
mGui = Tk()
button1 = Button(mGui,text ='Sklop',command = button1, height=5, width=20).pack()
mGui.mainloop()
It's also probably not a good idea to name your Button the same name as the function button1, that'll just cause confusion later on.
from tkinter import *
root = Tk()
root.title("Creater window")
def Img():
r = Toplevel()
r.title("My image")
canvas = Canvas(r, height=600, width=600)
canvas.pack()
my_image = PhotoImage(file='C:\\Python34\\Lib\idlelib\\Icons\\Baba.gif', master= root)
canvas.create_image(0, 0, anchor=NW, image=my_image)
r.mainloop()
btn = Button(root, text = "Click Here to see creator Image", command = Img)
btn.grid(row = 0, column = 0)
root.mainloop()
I have a tkinter program:
import urllib.request
from tkinter import *
root = Tk()
root.iconbitmap(default='icon.ico')
root.wm_title('Got Skills\' Skill Tracker')
frame = Frame(width="500",height="500")
frame.pack()
def show():
name = "zezima"
page = urllib.request.urlopen('http://hiscore.runescape.com/index_lite.ws?player=' + name)
page = page.readlines()
skills = []
for line in page:
skills.append([line.decode("utf-8").replace("\n", "").split(",")])
skills = skills[0:25]
for item in skills:
toPrint = item[0][0],"-",item[0][1],"-",item[0][1],"\n"
w = Message(frame, text=toPrint)
w.pack()
menu = Menu(root)
root.config(menu=menu)
filemenu = Menu(menu)
menu.add_cascade(label="Commands", menu=filemenu)
filemenu.add_command(label="Show Skills", command=show)
root.mainloop()
When I run the above script, it shows this (which is good):
alt text http://img708.imageshack.us/img708/8821/tkinter1.png
When I click Commands > Show Skills, it turns into this. (Linked because it's tall.) It shows the right thing, but...I can imagine you see the problem.
Two questions:
-How do I add a scrollbar to the frame, and keep the frame a fixed size? (Ideally, keep the size of the first image, add the output of show(), add a scrollbar to the first image of the program.)
-With the following code:
for item in skills:
toPrint = item[0][0],"-",item[0][1],"-",item[0][2],"\n"
w = Message(frame, text=toPrint)
w.pack()
Is that the best way to output what I'm outputting? The list (skills) looks like [[1,2,3],[4,5,6]..], and I want to display 1-2-3 on a line, 4 - 5 - 6 on a line, etc.
But, I don't want that extra line in between them like there is now, and I was wondering if how I did it is the best way to go about doing it.
To add the scroll bars, use tkinter.tix.ScrolledWindow.
To remove extra space drop the extra "\n" and display a string, not a tuple. Here is the complete code:
import urllib.request
from tkinter import *
from tkinter.tix import *
root = Tk()
root.iconbitmap(default='icon.ico')
root.wm_title('Got Skills\' Skill Tracker')
frame = Frame(width="500",height="500")
frame.pack()
swin = ScrolledWindow(frame, width=500, height=500)
swin.pack()
win = swin.window
def show():
name = "zezima"
page = urllib.request.urlopen('http://hiscore.runescape.com/index_lite.ws?player=' + name)
page = page.readlines()
skills = []
for line in page:
skills.append([line.decode("utf-8").replace("\n", "").split(",")])
skills = skills[0:25]
for item in skills:
toPrint = item[0][0],"-",item[0][1],"-",item[0][1]
w = Message(win, text=' '.join(toPrint), width=500)
w.pack()
menu = Menu(root)
root.config(menu=menu)
filemenu = Menu(menu)
menu.add_cascade(label="Commands", menu=filemenu)
filemenu.add_command(label="Show Skills", command=show)
root.mainloop()
Here's a class for scrolling frames. Just pass the window object as traditional tkinter style and use obj.frame as window for new widgets.
class ScrollableFrame:
