问题 I have a Python script that handles Modbus communications. One feature I added was a "graph" that shows the response times along with a color coded line that indicates if the response was successful, had an exception, or an error. The graph is just a scrollable canvas widget from Tkinter. After graphing a certain number of lines old lines will be deleted and then a new one will be added to the end. For this example I have it set to 10, which means there will never be more than 10 lines on the

问题 In the last couple of weeks, I've been trying to make an application that can read EEG data from OpenBCI Cyton (@250Hz) and plot a graph in 'real-time'. What seems to work better here are threads. I applied the tips I found here 1 to communicate the thread with Tkinter, but the application still doesn't work (gives me the error RecursionError: maximum recursion depth exceeded while calling a Python object ). Maybe I'm doing something wrong because I'm trying to use multiple .py files? See

问题 I have this little Tkinter GUI where I have a table. I want to make the text bold in the headings and also change its background color. I know that we can do this by ttk.Style() and configure but nothing is changing in the table. It's still looking plain or am I doing this wrong. Please help. from tkinter import ttk import tkinter as tk from tkinter import * window = tk.Tk() window.state('zoomed') treev = ttk.Treeview(window, selectmode ='browse') treev.place(x= 600, y= 200, width= 350,

问题 I have created a grid of buttons using the code below: for x in range(10): for y in range(10): btn = Button(frame, command=button_click(x, y)) btn.config(height=1, width=1) btn.grid(column=x, row=y, sticky='nsew') and I want to write the function button_click to turn the button a different colour once it has been clicked but as I have created all the buttons in a loop I don't have a specific variable name for each button so I'm not sure how best to do it? I didn't want to write 100 lines of

问题 I am making minesweeper game in Python and use tkinter library to create gui. Is there any way to bind to tkinter Button two commands, one when button is right-clicked and another when it's left clicked? 回答1: Typically buttons are designed for single clicks only, though tkinter lets you add a binding for just about any event with any widget. If you're building a minesweeper game you probably don't want to use the Button widget since buttons have built-in behaviors you probably don't want.
