To interact with objects contained in a Canvas object you need to use tag_bind() which has this format: tag_bind(item, event=None, callback=None, add=None) The item parameter can be either a tag or an id. Here is an example to illustrate the concept: from tkinter import * def onObjectClick(event): print(‘Got object click’, event.x, event.y) print(event.widget.find_closest(event.x, event.y)) root … Read more
If you don’t want to hide the root but just make sure the user can only interact with the popup, you can use grab_set() and grab_release(). Example app, tested with Python 3.7 and 3.8: import tkinter as tk import sys import platform class Popup: def __init__(self): self.tl = None self.root = tk.Tk() self.root.title(“Grab Set/Release”) tk.Label(self.root, … Read more
To change the icon you should use iconbitmap or wm_iconbitmap I’m under the impression that the file you wish to change it to must be an ico file. import tkinter as tk root = tk.Tk() root.iconbitmap(“myIcon.ico”)
I think this would meet your requirements. Here’s what the output looks like: First, A class named ToolTip which has methods showtip and hidetip is defined as follows: from tkinter import * class ToolTip(object): def __init__(self, widget): self.widget = widget self.tipwindow = None self.id = None self.x = self.y = 0 def showtip(self, text): “Display … Read more
Ok some more research found this helpful post which shows this is occuring because of X’s autorepeat behaviour. You can disable this by using os.system(‘xset r off’) and then reset it using “on” at the end of your script. The problem is this is global behaviour – not just my script – which isn’t great … Read more
Advanced zoom example. Like in Google Maps. Example video (longer video here): It zooms only a tile, but not the whole image. So the zoomed tile occupies constant memory and not crams it with a huge resized image for the large zooms. For the simplified zoom example look here. Tested on Windows 7 64-bit and … Read more
There is no single magic function to force a frame to a minimum or fixed size. However, you can certainly force the size of a frame by giving the frame a width and height. You then have to do potentially two more things: when you put this window in a container you need to make … Read more
you can use multiprocessing module to implement a Pipe between the two modules. Then you can start one of the modules as a Process and use the Pipe to communicate with it. The best part about using pipes is you can also pass python objects like dict,list through it. Ex: mp2.py: from multiprocessing import Process,Queue,Pipe … Read more
Just use widget.config(highlightbackground=COLOR) Furthermore, if you don’t want that border at all, set the highlightthickness attribute to 0 (zero).
When you pack the widget you can use self.a_button = Button(root, text=”A Button”) self.a_button.grid(row=0, column=1, padx=10, pady=10) Using padx and pady you can add padding to the outer side of the button and alternatively if you want to increase the size of the button you can add inner padding using ipadx and ipady. If you … Read more
