我试图让命令在现有按钮下添加/添加新按钮以打开像blender style gui这样的新窗口？
from tkinter import*
from tkinter import ttk
import tkinter as tk
#creating frame to basic window, add scrollbar to canvas and background image
class mainWindow:
def __init__(self, master):
frame = ttk.Frame(master).pack(fill=X)
cv = tk.Canvas(frame, scrollregion=(0,0,270,2750), height=2800, width=270, bg = "cyan")
self.image1 = PhotoImage(file="logoQs270x700.png")
image = cv.create_image(0, 0, anchor = NW, image=self.image1)
scb = tk.Scrollbar(frame, command=cv.yview)
cv.pack(side=LEFT)
scb.pack(side=RIGHT, fill=Y)
cv.configure(yscrollcommand=scb.set)
a='white'
b='purple'
c=22
f = 'Neuropol'
g = GROOVE
h = 'violet'
#basic button
btn1 = tk.Button(frame, text = "Site Prep", fg = a, anchor = W, font = f)
btn1.configure(width = c, activebackground = h, relief = g, bg = b)
btn1_window = cv.create_window(5, 5, anchor=NW, window=btn1)
#basic window
root = tk.Tk()
root.title('Built Up Rates')
root.geometry('280x700+0+0')
A=mainWindow(root)
root.mainloop()
这个想法是当点击它打开时，有一个像标题一样的按钮 在它下面的子标题并向下移动它下面的现有按钮 如果再次单击相同的按钮，它会向上移动标题按钮并隐藏 子标题或子标签.. [徽标图片] [1] [搅拌机Gui样品未激活] [2] [激活时的搅拌器Gui样本] [3]

我的建议是使用框架而不是画布。使用框架，您可以使用pack，它擅长从上到下堆叠小部件。您无需进行任何计算即可将小部件放置在正确的位置。
小部件中的每个部分都应该是一个框架，然后您只需将它们从上到下打包。在该部分中，您需要两个小部件：标题的标签和内容的框架。打开和关闭该部分只需要在内部框架上调用pack或pack_forget。
由于python是面向对象的，因此您应该将每个可扩展部分视为一个对象。您的GUI整体上变成了从上到下堆叠的这些对象的集合。我们可以创建一个负责展开/折叠机制的基类，子类可以添加它们需要在框架内显示的任何小部件。
让我们从可扩展框架的基类开始。我们将创建用于打开或关闭框架的小部件，并且我们将创建一个内部框架来保存按钮和属于该框架的其他东西。我们将添加一个分隔符，以模仿您问题中屏幕截图的外观。
import Tkinter as tk
import ttk
class ExpandoFrame(tk.Frame):
closed_glyph = u"\u25b6"
opened_glyph = u"\u25bc"
def __init__(self, parent, title):
tk.Frame.__init__(self, parent, borderwidth=0)
self.title = title
self.sep = ttk.Separator(self, orient="horizontal")
self.header = tk.Label(self, width=20, anchor="w")
self.inner = tk.Frame(self)
self.sep.pack(side="top", fill="x")
self.header.pack(fill="x", padx=4)
self.collapse()
self.header.bind("<1>", self.toggle)
这个类有三个方法：一个用于显式扩展该部分，一个用于显式地折叠它，另一个用于从一个切换到另一个。
def toggle(self, event=None):
if self.closed_glyph in self.header.cget("text"):
self.expand()
else:
self.collapse()
def expand(self):
self.header.configure(text="%s %s" % (self.opened_glyph, self.title))
self.inner.pack(side="top", fill="both", expand=True)
def collapse(self):
self.header.configure(text="%s %s" % (self.closed_glyph, self.title))
self.inner.pack_forget()
这为我们奠定了基础。现在，每个子类都可以在内部框架中放置它想要的任何小部件。以下是几个例子：
class SectionSitePrep(ExpandoFrame):
def __init__(self, parent):
ExpandoFrame.__init__(self, parent, "Site Preparation")
self.cb1 = tk.Checkbutton(self.inner, text="Choose this")
self.cb2 = tk.Checkbutton(self.inner, text="Or this")
self.cb1.pack(side="top", anchor="w")
self.cb2.pack(side="top", anchor="w")
class SectionWblff(ExpandoFrame):
def __init__(self, parent):
ExpandoFrame.__init__(self, parent, "WBLFF")
self.rbvar = tk.StringVar(value=1)
self.rb1 = tk.Radiobutton(self.inner, text="One", variable=self.rbvar, value=1)
self.rb2 = tk.Radiobutton(self.inner, text="Two", variable=self.rbvar, value=2)
self.rb3 = tk.Radiobutton(self.inner, text="Three", variable=self.rbvar, value=3)
self.rb1.pack(side="left")
self.rb2.pack(side="left")
self.rb3.pack(side="left")
最后，你可以将这些部分从上到下放在一个pack的框架中：
class Example(tk.Frame):
def __init__(self, parent):
tk.Frame.__init__(self, parent)
s1 = SectionSitePrep(self)
s2 = SectionWblff(self)
s1.pack(side="top", fill="x")
s2.pack(side="top", fill="x")

简单且有效;）通过作弊..它与同一帧中的现有按钮重叠并打开按钮的新命令..使用包，网格和帧销毁

这实际上有效。扩展风格tittle ..通过作弊..重叠技术现有主要按钮在框架中，使用pack，grid和frame.destroy（）并使用新命令，从而附加所需按钮：）
