我在 tkinter 上工作，这里提供了一个可滚动框架类： https://gist.github.com/mp035/9f2027c3ef9172264532fcd6262f3b01
该类的实际代码是：
class ScrollFrame(ttk.Frame):
def __init__(self, parent):
super().__init__(parent) # create a frame (self)
s=ttk.Style()
s.configure('TFrame', background="#eff0f1")
#place canvas on self
self.canvas = tk.Canvas(self, borderwidth=0, background="#eff0f1", height = appHeight)
#place a frame on the canvas, this frame will hold the child widgets
self.viewPort = ttk.Frame(self.canvas, style='TFrame')
#place a scrollbar on self
self.vsb = ttk.Scrollbar(self, orient="vertical", command=self.canvas.yview)
#attach scrollbar action to scroll of canvas
self.canvas.configure(yscrollcommand=self.vsb.set)
#pack scrollbar to right of self
self.vsb.pack(side="right", fill="y")
#pack canvas to left of self and expand to fil
self.canvas.pack(side="left", fill="both", expand=True)
self.canvas_window = self.canvas.create_window((4,4),
#add view port frame to canvas
window=self.viewPort, anchor="nw",
tags="self.viewPort")
#bind an event whenever the size of the viewPort frame changes.
self.viewPort.bind("<Configure>", self.onFrameConfigure)
#bind an event whenever the size of the viewPort frame changes.
self.canvas.bind("<Configure>", self.onCanvasConfigure)
#perform an initial stretch on render, otherwise the scroll region has a tiny border until the first resize
self.onFrameConfigure(None)
def onFrameConfigure(self, event):
'''Reset the scroll region to encompass the inner frame'''
#whenever the size of the frame changes, alter the scroll region respectively.
self.canvas.configure(scrollregion=self.canvas.bbox("all"))
def onCanvasConfigure(self, event):
'''Reset the canvas window to encompass inner frame when required'''
canvas_width = event.width
#whenever the size of the canvas changes alter the window region respectively.
self.canvas.itemconfig(self.canvas_window, width = canvas_width)
它实际上工作得很好，除了我不能让鼠标滚轮在滚动条上工作......我必须单击滑块并使其滑动。每当我尝试使用鼠标滚轮滚动时，我都会在控制台中收到此错误：
Traceback (most recent call last):
File "D:\Anaconda\lib\tkinter\__init__.py", line 1705, in __call__
return self.func(*args)
File "D:\Anaconda\lib\tkinter\__init__.py", line 1739, in yview
res = self.tk.call(self._w, 'yview', *args)
_tkinter.TclError: unknown option "": must be moveto or scroll
我找到了这个主题： tkinter：将鼠标滚轮绑定到滚动条
但是为适应我的课程而给出的答案似乎都不起作用。
有谁知道如何调整我的可滚动框架以使鼠标滚轮正常工作？ 预先感谢！
好的，我找到了答案，所以我在这里发布解决方案：
在 init 的末尾，我添加了以下内容：
self.viewPort.bind('<Enter>', self._bound_to_mousewheel)
self.viewPort.bind('<Leave>', self._unbound_to_mousewheel)
然后我添加了这个：
def _bound_to_mousewheel(self, event):
self.canvas.bind_all("<MouseWheel>", self._on_mousewheel)
def _unbound_to_mousewheel(self, event):
self.canvas.unbind_all("<MouseWheel>")
def _on_mousewheel(self, event):
self.canvas.yview_scroll(int(-1*(event.delta/120)), "units")
我现在可以用鼠标滚轮滚动栏，无论指针在哪里！
所以这是完全工作的可滚动框架类代码：
class ScrollFrame(ttk.Frame):
def __init__(self, parent):
super().__init__(parent) # create a frame (self)
s=ttk.Style()
s.configure('TFrame', background="#eff0f1")
#place canvas on self
self.canvas = tk.Canvas(self, borderwidth=0, background="#eff0f1", height = appHeight)
#place a frame on the canvas, this frame will hold the child widgets
self.viewPort = ttk.Frame(self.canvas, style='TFrame')
#place a scrollbar on self
self.vsb = ttk.Scrollbar(self, orient="vertical")
#attach scrollbar action to scroll of canvas
self.canvas.configure(yscrollcommand=self.vsb.set)
#pack scrollbar to right of self
self.vsb.pack(side="right", fill="y")
#pack canvas to left of self and expand to fil
self.canvas.pack(side="left", fill="both", expand=True)
self.canvas_window = self.canvas.create_window((4,4),
#add view port frame to canvas
window=self.viewPort, anchor="nw",
tags="self.viewPort")
#bind an event whenever the size of the viewPort frame changes.
self.viewPort.bind("<Configure>", self.onFrameConfigure)
#bind an event whenever the size of the viewPort frame changes.
self.canvas.bind("<Configure>", self.onCanvasConfigure)
#perform an initial stretch on render, otherwise the scroll region has a tiny border until the first resize
self.onFrameConfigure(None)
self.viewPort.bind('<Enter>', self._bound_to_mousewheel)
self.viewPort.bind('<Leave>', self._unbound_to_mousewheel)
def _bound_to_mousewheel(self, event):
self.canvas.bind_all("<MouseWheel>", self._on_mousewheel)
def _unbound_to_mousewheel(self, event):
self.canvas.unbind_all("<MouseWheel>")
def _on_mousewheel(self, event):
self.canvas.yview_scroll(int(-1*(event.delta/120)), "units")
def onFrameConfigure(self, event):
'''Reset the scroll region to encompass the inner frame'''
#whenever the size of the frame changes, alter the scroll region respectively.
self.canvas.configure(scrollregion=self.canvas.bbox("all"))
def onCanvasConfigure(self, event):
'''Reset the canvas window to encompass inner frame when required'''
canvas_width = event.width
#whenever the size of the canvas changes alter the window region respectively.
self.canvas.itemconfig(self.canvas_window, width = canvas_width)
当你想在 tkinter 中创建页面时，你所要做的就是这样调用它：
class NewPage(ttk.Frame):
def __init__(self, parent, controller):
ttk.Frame.__init__(self, parent)
self.scrollFrame = ScrollFrame(self)
如果你想在其中添加小部件，只需使用“self.scrollFrame.viewPort”构建它们，如下所示：
label = ttk.Label(self.scrollFrame.viewPort, text = "Label", anchor = "center")
