我将如何解决这个问题Tcl将确保checkbutton，spinbox和radiobutton widgets都与数组变量相关联。然后，我会在数组上放置一个跟踪，这将导致每次写入变量时调用函数。 Tcl令人无聊。

How I would solve this in Tcl would be to make sure that the checkbutton, spinbox and radiobutton widgets are all associated with an array variable. I would then put a trace on the array which would cause a function to be called each time that variable is written. Tcl makes this trivial.

不幸的是，Tkinter不支持使用Tcl数组。幸运的是，这很容易入侵。如果你是冒险的，请尝试以下代码。

Unfortunately Tkinter doesn't support working with Tcl arrays. Fortunately, it's fairly easy to hack in. If you're adventurous, try the following code.

从全面披露部门：我今天早上在大约半个小时内将这一扔了。我没有在任何真正的代码中实际使用这种技术。但是，我无法抗拒挑战，想知道如何使用Tkinter使用数组。

From the full disclosure department: I threw this together this morning in about half an hour. I haven't actually used this technique in any real code. I couldn't resist the challenge, though, to figure out how to use arrays with Tkinter.
