滾動條沒有填充或出現（tkinter）

Question

我的滾動條有問題。 我嘗試了一些放置它的解決方案，但每次都遇到了一些麻煩。 有時我看不到滾動條，有時它沒有填滿y-axis 。

首先，我嘗試不使用畫布，僅使用框架（ allTelemtry ）並使用grid() ，但無法實現工作滾動條。 然后我嘗試使用 canvas 以便可以使用pack() ，但它仍然無法正常工作。

from tkinter import *
from tkinter import ttk

root = Tk()
root.state('zoomed')

# creating notebook
telemetry = ttk.Notebook(root, width=1083, height=200)
telemetry.place(x=440, y=560)

allTelemetry = Frame(telemetry)
allTelemetry.pack(fill="both", expand = 1)

# creating canvas for scrollbar 
allTelemetryCanvas = Canvas(allTelemetry)
allTelemetryCanvas.pack(fill="both", expand = 1)

dotTelemetry = Frame(telemetry)
dotTelemetry.pack(fill="both", expand = 1)

telemetry.add(allTelemetry, text= u"Hepsini Goster")
telemetry.add(dotTelemetry, text= u"Anlik Telemetri")

#------------------------------------------------------------
teleTitle = [" ", "Takmno","Paketno","Zaman",
        "1Basn","2Basn",
        "Nem",
        "1kseklik","2Ykseklik",
        "rtifaFark","niHz","Scaklk","PilGerilimi",
        "La1","Lo1","Al1",
        "La2","Lo2","Al2",
        "Drm",
        "x","y","z",
        "DnSays","Video"]

empty = Label(allTelemetryCanvas, text="",width=3)
empty.grid(row=0,column=0,padx=1, pady=1)
for j in range(1,25):
    teleTitle[j] = teleTitle[j].encode('UTF-8')

    entry = Label(allTelemetryCanvas,text=teleTitle[j].decode(),anchor='w', width=5, bd=2)
    entry.grid(row=0, column=j,padx=1, pady=1)

packet=1
for i in range(1,10):
    packetNum = Label(allTelemetryCanvas, text = packet, anchor="w",width=3)
    packetNum.grid(row=i, column=0,pady=0.5)
    packet = packet+1
    for j in range(1,25):
        takenData = Entry(allTelemetryCanvas,width=5)
        takenData.grid(row=i, column=j,pady=0.5)

# !!!!!!!!!!!!!!!!!
scrollbar = ttk.Scrollbar(allTelemetry, orient='vertical', command=allTelemetryCanvas.yview)
scrollbar.pack(side=RIGHT, fill="y")
allTelemetryCanvas['yscrollcommand'] = scrollbar.set


root.mainloop()

Answer 1

在第 24 行，我添加了allTelemetryCanvas.create_window 。 在第 27-32 行，我添加了dotTelemetry.bind 。 我在mainloop()之前的第 66 行替換了allTelemetryCanvas.configure 。

from tkinter import *
from tkinter import ttk

root = Tk()
root.state('zoomed')

# creating notebook
telemetry = ttk.Notebook(root, width=1083, height=200)
telemetry.place(x=440, y=560)

allTelemetry = Frame(telemetry)
allTelemetry.pack(fill="both", expand = 1)

# creating canvas for scrollbar 
allTelemetryCanvas = Canvas(allTelemetry)
allTelemetryCanvas.pack(side="left", fill="both", expand=True)

dotTelemetry = Frame(telemetry)
dotTelemetry.pack(fill="both", expand = 1)

telemetry.add(allTelemetry, text= u"Hepsini Goster")
telemetry.add(dotTelemetry, text= u"Anlik Telemetri")

allTelemetryCanvas.create_window((0, 0), window=dotTelemetry, anchor="nw")


dotTelemetry.bind(
    "<Configure>",
    lambda e: allTelemetryCanvas.configure(
        scrollregion=allTelemetryCanvas.bbox("all")
      )
)

allTelemetryCanvas.configure(yscrollcommand=scrollbar.set)

root.mainloop()
