Question

I am designing a gui with Tkinter and specific buttons are misbehaving. The main app window includes a button to connect to a machine. The button command works fine, as the connection is successful, but the button does not change relief or color when clicked. If I click out of the app (or create a new window via one of the buttons inside the app), then click back to the main window, the button looks exactly as intended. It is only on startup that the button decides to be lazy.

Once the machine is connected, it brings up more buttons that look and operate correctly, it is only the first button that is a problem. Below are some pictures of the buttons and how they look before and after connecting.

New buttons after connecting

If it helps, I am using OSX 10.10 with updated Python 3.6.5(64-bit for OSX ~~10.6+~~ 10.9+),~~, as well as ActiveTcl version 8.5.18.0~~.

The following code brings up a test button with the same problem.

import tkinter as tk

if __name__ == '__main__':
    root = tk.Tk()
    root.title('Button Test')

    button = tk.Button(root, text = 'test me', padx= '20', pady = '20')
    button.grid()

    root.mainloop()

EDIT: I have searched around and found that some people fixed issues similar to this by updating Python/Tcl packages, but my issue seems to be persistent.

EDIT2: I tried changing the type from tk.Button() to tk.ttk.Button() and this seems to fix the visual bug, but it draws a grey border around the new button due to the default "style" option. That is a separate issue however and others have asked how to fix it on here.

Answer 1

我也一直在对此进行研究，显然Mac OSX不支持按钮或浮雕样式的背景色。您可以找到它IronPDF。

但是，我发现有一个模块可以对OSX进行更多自定义。您可以找到它Here

Answer 2

我在这里看到几个错别字。

变化：

import tkinter as tk

if __name__ = '__main__': # needs to be == not =.
    root = tk.Tk()
    root.title('Button Test')
    # test= should be text=. remove command if you are not using it.
    # typo in padx. padx '20; should be padx='20'
    button = tk.Button(root, test = 'test me', command = None, padx '20;, pady = '20')
    button.grid()

    root.mainloop()

对此：

import tkinter as tk

if __name__ == '__main__':
    root = tk.Tk()
    root.title('Button Test')

    button = tk.Button(root, text='test me', padx='20', pady='20')
    button.grid()

    root.mainloop()

Tkinter button relief on OSX not changing until I switch windows
