如何在 Tkinter 中实现可滚动 Frame

from tkinter import *

def addCheck(type, homeFrame):
    '''adds a new row to the profile editor which allows the user to input a check'''
    if type == 'g':
        checkLength = 14
        listLength = len(gCheckList)
    elif type == 't':
        checkLength = 9
        listLength = len(tCheckList)
    else:
        checkLength = 0

    checkFrame = Frame(homeFrame)
    checkFrame.grid(row=2 + listLength,column=0,padx=10,pady=5)

    checkName = Text(checkFrame, width=10, height=1, font=('Courier',12))
    checkName.grid(row=0, column=0,padx=10,pady=5)

    if type == 'g':
        gCheckList.append(checkFrame)
    elif type == 't':
        tCheckList.append(checkFrame)
    else:
        return

    homeFrame.update_idletasks()

    return

#creates root
root = Tk()
root.title = 'Profile Editor'
# Suggest to remove root.geometry(...) because the window is not tall enough to show all the widgets.
#root.geometry('750x300+250+225')

#creates profile name frame
profileNameFrame = Frame(root)
profileNameFrame.grid(row=0,column=0,padx=10,pady=5)

#Creates a spot to name the profile
nameLabel = Label(profileNameFrame, text='Profile Name: ', font=('Courier',12))
nameLabel.grid(row=0,column=0,padx=10,pady=5)
nameText = Text(profileNameFrame, width=30, height=1, font=('Courier',12))
nameText.grid(row=0, column=1,padx=10,pady=5)

#Frame for title
titleFrame = Frame(root)
titleFrame.grid(row=1,column=0,padx=10,pady=5)
gCheckProfileLabel = Label(titleFrame, text='header', font=('Courier',14))
gCheckProfileLabel.grid(row=0,column=0,padx=10,pady=5)

#Frame for headers

#frame for canvas
checkFrame = Frame(titleFrame)

checkFrame.grid_rowconfigure(0,weight=1)
checkFrame.grid_columnconfigure(0,weight=1)
# don't call .grid_propagate(False)
#checkFrame.grid_propagate(False)

#canvas for scrollbar
scrollCanvas = Canvas(checkFrame, bg='yellow')
scrollCanvas.grid(row=0,column=0,sticky='news')

#link scrollbar to canvas
gScrollbar = Scrollbar(checkFrame, orient='vertical',command=scrollCanvas.yview)
gScrollbar.grid(row=0,column=1,sticky='ns')
scrollCanvas.configure(yscrollcommand=gScrollbar.set)

#Create frame to contain checks
gChecksFrame = Frame(scrollCanvas, bg='blue')
scrollCanvas.create_window((0,0),window=gChecksFrame, anchor='nw')
# don't call gChecksFrame.grid(...)
#gChecksFrame.grid(row=1,column=1,padx=10,pady=5)

# update canvas scrollregion whenever gChecksFrame is resized
gChecksFrame.bind("<Configure>", lambda e: scrollCanvas.config(scrollregion=scrollCanvas.bbox("all")))

#Creates a new check row to be added into the program
addGCheckButton = Button(titleFrame, text='+', font=('Courier',14), command=lambda: addCheck('g', gChecksFrame))
addGCheckButton.grid(row=0,column=2,padx=1,pady=5)

root.mainloop()
