Python Tkinter：将滚动条附加到列表框而不是窗口

Question

这是我目前窗口的截图：

我的问题是我根本无法让滚动条出现在列表框的右侧而不是主窗口的右侧。代码在这里：

from Tkinter import *

def onselect(event):
    w = event.widget
    index = int(w.curselection()[0])
    value = w.get(index)
    info = find_info(value)
    listSelection.delete(0, END)
    listSelection.insert(END, "Node ID: " + info[0])
    listSelection.insert(END, "Owner/Description: " + info[1])
    listSelection.insert(END, "Last Latitude: " + info[2])
    listSelection.insert(END, "Last Longitude: " + info[3])



mapNodes = "http://ukhas.net/api/mapNodes"
nodeData = "http://ukhas.net/api/nodeData"
current_id = 0

window = Tk() # create window
window.configure(bg='lightgrey')
window.title("UKHASnet Node Manager")
window.geometry("680x400")

lbl1 = Label(window, text="Node List:", fg='black', font=("Helvetica", 16, "bold"))
lbl2 = Label(window, text="Node Information:", fg='black', font=("Helvetica", 16,"bold"))
lbl1.place(x=0, y=0)
lbl2.place(x=200, y=0)

scrollbar = Scrollbar(window, orient="vertical")
listNodes = Listbox(window, width=20, height=20, yscrollcommand=scrollbar.set, font=("Helvetica", 12))
scrollbar.config(command=listNodes.yview)
scrollbar.pack(side="right", fill="y")

listSelection = Listbox(window, width=50, height=4, font=("Helvetica", 12))

# pack objects onto window
listNodes.place(x=1, y=40)
listSelection.place(x=200, y=40)

感谢任何帮助，我正在运行 Ubuntu 14.04 和 Python 2.7.5

Answer 1

您已将滚动条附加到 window

Scrollbar(window, orient="vertical")

尝试附加到listNodes

Scrollbar(listNodes, orient="vertical")

或使用Listbox 创建Frame 并将滚动条附加到该框架。

编辑：Frame的示例

from Tkinter import *

window = Tk()
window.geometry("680x500")

Label(window, text="Top label").pack()

frame = Frame(window)
frame.pack()

listNodes = Listbox(frame, width=20, height=20, font=("Helvetica", 12))
listNodes.pack(side="left", fill="y")

scrollbar = Scrollbar(frame, orient="vertical")
scrollbar.config(command=listNodes.yview)
scrollbar.pack(side="right", fill="y")

listNodes.config(yscrollcommand=scrollbar.set)

for x in range(100):
    listNodes.insert(END, str(x))

Label(window, text="Bottom label").pack()

window.mainloop()

编辑： 代码中的框架 - 我使用 grid/pack，因为我更喜欢它。

我添加了一些代码，所以现在在窗口调整大小时列出调整大小。

from Tkinter import *

def onselect(event):
    w = event.widget
    index = int(w.curselection()[0])
    value = w.get(index)
    info = find_info(value)
    listSelection.delete(0, END)
    listSelection.insert(END, "Node ID: " + info[0])
    listSelection.insert(END, "Owner/Description: " + info[1])
    listSelection.insert(END, "Last Latitude: " + info[2])
    listSelection.insert(END, "Last Longitude: " + info[3])



mapNodes = "http://ukhas.net/api/mapNodes"
nodeData = "http://ukhas.net/api/nodeData"
current_id = 0

window = Tk() # create window
window.configure(bg='lightgrey')
window.title("UKHASnet Node Manager")
window.geometry("680x400")

lbl1 = Label(window, text="Node List:", fg='black', font=("Helvetica", 16, "bold"))
lbl2 = Label(window, text="Node Information:", fg='black', font=("Helvetica", 16,"bold"))
lbl1.grid(row=0, column=0, sticky=W)
lbl2.grid(row=0, column=1, sticky=W)

frm = Frame(window)
frm.grid(row=1, column=0, sticky=N+S)
window.rowconfigure(1, weight=1)
window.columnconfigure(1, weight=1)

scrollbar = Scrollbar(frm, orient="vertical")
scrollbar.pack(side=RIGHT, fill=Y)

listNodes = Listbox(frm, width=20, yscrollcommand=scrollbar.set, font=("Helvetica", 12))
listNodes.pack(expand=True, fill=Y)

scrollbar.config(command=listNodes.yview)

listSelection = Listbox(window, height=4, font=("Helvetica", 12))
listSelection.grid(row=1, column=1, sticky=E+W+N)


for x in range(100):
    listNodes.insert(END, x)

for x in "ABCD":
listSelection.insert(END, x + ": ?")

Answer 2

由于您使用的是place（我不推荐），所以只需做一些数学运算来计算滚动条的位置。

在这种特定情况下，更好的选择是使用grid，因为您显然希望将事物组织成行和列。标题位于第 0 行，列表框/滚动条组合位于第 1 行。第一个标题位于第 0 列和第 1 列，列表框位于第 0 列，滚动条位于第 1 列。第二个标题位于第 2 列，而另一个列表框进入第 3 列。
