我想根据用户是否点击它来定制tkinter PanedWindow上的窗扇的外观，所以我用这个来做。
import tkinter as tkfrom tkinter import ttkclass PanedTest(tk.Tk):def __init__(self, master = None) -> None:super().__init__(master)self.style = ttk.Style()self.style.configure('TPanedwindow', background='black')self.style.configure('Clicked.TPanedwindow', background='blue')self.style.configure('Sash', sashthickness = 8)self.bind_class('TPanedwindow', '<Button-1>', lambda e : e.widget.configure(style = 'Clicked.TPanedwindow'))self.bind_class('TPanedwindow', '<B1-Motion>', lambda e : e.widget.sash_place(0, e.x, e.y))self.bind_class('TPanedwindow', '<ButtonRelease-1>', lambda e : e.widget.configure(style = 'TPanedwindow'))self.paned1 = ttk.PanedWindow()self.paned1.pack()self.frame1 = ttk.Frame(self.paned1, width = 200, height = 200)self.paned1.add(self.frame1)self.frame2 = ttk.Frame(self.paned1, width = 200, height = 200)self.paned1.add(self.frame2)self.paned2 = ttk.PanedWindow(orient = 'horizontal')self.paned2.pack()self.frame3 = ttk.Frame(self.paned2, width = 200, height = 200)self.paned2.add(self.frame3)self.frame4 = ttk.Frame(self.paned2, width = 200, height = 200)self.paned2.add(self.frame4)if __name__ == "__main__":app = PanedTest()app.mainloop()
不幸的是，这会导致错误
Exception in Tkinter callbackTraceback (most recent call last):File "C:\Program Files\Python310\lib\tkinter\__init__.py", line 1921, in __call__return self.func(*args)File "paned_test.py", line 15, in <lambda>self.bind_class('TPanedwindow', '<B1-Motion>', lambda e : e.widget.sash_place(0, e.x, e.y))File "C:\Program Files\Python310\lib\tkinter\__init__.py", line 4490, in sash_placereturn self.sash("place", index, x, y)File "C:\Program Files\Python310\lib\tkinter\__init__.py", line 4464, in sashself.tk.call((self._w, 'sash') + args)) or ()_tkinter.TclError: wrong # args: should be ".!panedwindow2 sashpos index ?newpos?"
所以经过大量的测试，我设法让它和这个一起工作
import tkinter as tkfrom tkinter import ttkclass PanedTest(tk.Tk):def __init__(self, master = None) -> None:super().__init__(master)self.style = ttk.Style()self.style.configure('TPanedwindow', background='black')self.style.configure('Clicked.TPanedwindow', background='blue')self.style.configure('Sash', sashthickness = 8)self.bind_class('TPanedwindow', '<Button-1>', lambda e : e.widget.configure(style = 'Clicked.TPanedwindow'))self.bind_class('TPanedwindow', '<B1-Motion>', lambda e : e.widget.sash(0, (e.x if str(e.widget.cget('orient')) == 'horizontal' else e.y)))self.bind_class('TPanedwindow', '<ButtonRelease-1>', lambda e : e.widget.configure(style = 'TPanedwindow'))self.paned1 = ttk.PanedWindow()self.paned1.pack()self.frame1 = ttk.Frame(self.paned1, width = 200, height = 200)self.paned1.add(self.frame1)self.frame2 = ttk.Frame(self.paned1, width = 200, height = 200)self.paned1.add(self.frame2)self.paned2 = ttk.PanedWindow(orient = 'horizontal')self.paned2.pack()self.frame3 = ttk.Frame(self.paned2, width = 200, height = 200)self.paned2.add(self.frame3)self.frame4 = ttk.Frame(self.paned2, width = 200, height = 200)self.paned2.add(self.frame4)if __name__ == "__main__":app = PanedTest()app.mainloop()
我现在可以拖动窗格窗口，但它也给予这个错误
Exception in Tkinter callbackTraceback (most recent call last):File "C:\Program Files\Python310\lib\tkinter\__init__.py", line 1921, in __call__return self.func(*args)File "paned_test.py", line 48, in <lambda>self.bind_class('TPanedwindow', '<B1-Motion>', lambda e : e.widget.sash(0, (e.x if str(e.widget.cget('orient')) == 'horizontal' else e.y)))File "C:\Program Files\Python310\lib\tkinter\__init__.py", line 4463, in sashreturn self._getints(File "C:\Program Files\Python310\lib\tkinter\__init__.py", line 1467, in _getintsreturn tuple(map(self.tk.getint, self.tk.splitlist(string)))TypeError: splitlist() argument must be str, bytes or bytearray, not int
下面是两个脚本之间的区别
self.bind_class('TPanedwindow', '<B1-Motion>', lambda e : e.widget.sash_place(0, e.x, e.y))
vs
self.bind_class('TPanedwindow', '<B1-Motion>', lambda e : e.widget.sash(0, (e.x if str(e.widget.cget('orient')) == 'horizontal' else e.y)))
为什么只有第二个函数起作用，而不是专门针对我要做的事情的函数？
哦，把e.widget.cget('orient')转换成str只是因为结果是<class '_tkinter.Tcl_Obj'>。

这可能是
tkinter上的一个bug。对于使用e.widget.sash_place(0, e.x, e.y)的第一个代码，它只是在内部调用self.sash('place', index, x, y)，这会引发参数数量无效错误，因为.sash()只需要两个参数，index和pos（即index和pos）。如何在第二个代码块中使用.sash()。但是在
.sash()内部，它在self.tk.call(...)的结果上调用self._getints()，self.tk.call(...)是一个整数，但是self._getints()需要一个字符串。这就是第二个错误的含义。为了避免第二个错误，可以直接使用
e.widget.tk.call()而不是.sash()：
