Tkinter中标签框架的滚动条

Question

I am trying to create a scroll bar for a window created in my gui using tk.Toplevel. The frame currently often fills up with long grids of strings that are added one buy one. The rest of the GUI allows a user to write to a series of fields which are displayed one after another using a grid.

The data might look something like this:

sadas sfafaf fsaafads fdsafsf dfsfdsf fssfs fsfsfsfs fsfsfs sfsfsfs fsssfsfsf

sadas sfafaf fsaafads fdsafsf dfsfdsf fssfs fsfsfsfs fsfsfs sfsfsfs fsssfsfsf

sadas sfafaf fsaafads fdsafsf dfsfdsf fssfs fsfsfsfs fsfsfs sfsfsfs fsssfsfsf

I used this post: Adding a scrollbar to a group of widgets in Tkinter as a guide to get to where I am right now. Currently, when I open the window the scroll bar appears on the left side. As soon as I add a line the GUI freezes and I have to close it.

Here is the relevant code:

class data_popup():
    def __init__(self, parent):
        self.parent = parent
        self.top = tk.Toplevel(parent)
        self.top.title("Current Data")
        self.top.protocol('WM_DELETE_WINDOW', self.stop_close)
        #Frames
        self.header_labels_frame = tk.Frame(self.top)
        self.header_labels_frame.pack(side = tk.TOP)
        self.data_frame_1 = tk.Frame(self.top)
        self.data_frame_1.pack(side = tk.BOTTOM)        
        self.header_labels_list = []


        self.data_canvas = tk.Canvas(self.data_frame_1, borderwidth = 0)
        self.data_frame = tk.Frame(self.data_canvas)
        self.scrollbar = tk.Scrollbar(self.data_frame, orient = 'vertical', command = self.data_canvas.yview)
        self.data_canvas.configure(yscrollcommand = self.scrollbar.set)
        self.scrollbar.pack(side = 'right', fill = 'y')
        self.data_canvas.pack(side = "bottom", fill = 'both', expand = True)
        self.data_canvas.create_window((4,4), window = self.data_frame, anchor = 'nw', tags = "self.frame")
        self.data_frame.bind("<Configure>", self.myfunction)
        self.create_header()
        self.data_row_list = list()

    def myfunction(self, event):
        self.data_canvas.configure(scrollregion=self.data_canvas.bbox("all"))

Answer 1

Often, when a GUI freezes in the manner you describe, it is because you use both grid and pack in the same frame. You aren't showing the code where you add something to the frame, but my guess is, that is what is happening.
