Tkinter is widely used to create GUI-based applications. It provides various widgets including buttons, text boxes, and labels. We can customize the position of widgets and retrieve their coordinates on the tkinter frame using geometry methods. To get the actual coordinates of a widget, we can use the geometry methods available in tkinter's library. The winfo_rootx() and winfo_rooty() functions return the actual coordinates of the widget with respect to the root window. Syntax widget.winfo_rootx() # Returns x-coordinate widget.winfo_rooty() # Returns y-coordinate Example Here's how to get the current coordinates of different ... Read More
