Question

我有一个简单的GUI，其中包含三个框架。这些框架之一是包含画布的笔记本框架。问题在于笔记本框架无法展开以适合窗口。我尝试了grid（）和pack（）的所有不同组合。似乎对我没有任何帮助。所以我终于来了。我希望这里的人可以告诉我我做错了什么。包括我的代码的精简版：

    from tkinter import *
import ttk

window = Tk()
window.geometry("640x480")
window.title("Notebook Test")

options_list = ["one", "two", "three"]

def doNothing():
    pass

leftFrame = Frame(window)
tabFrame = Frame(window)
statusFrame = Frame(window)

leftFrame.grid(row=0, column=0, sticky="n")
tabFrame.grid(row=0, column=1, sticky="nw")
statusFrame.grid(row=2, column=0, columnspan=2, sticky="ew")

Xlabel = Label(leftFrame, text="X Function", anchor=N)
Xlabel.pack()
x_var = StringVar(leftFrame)
x_menu = ttk.Combobox(leftFrame, textvariable=x_var)
x_menu["values"] = options_list
x_menu.current(0)
x_menu.pack()

tab_control = ttk.Notebook(tabFrame)
tab1 = ttk.Frame(tab_control)
tab2 = ttk.Frame(tab_control)
tab_control.add(tab1, text="Default One")
tab_control.add(tab2, text="Default Two")
tab_control.grid()

canvas1 = Canvas(tab1, bg="blue")
canvas2 = Canvas(tab2, bg="green")

canvas1.grid()
canvas2.grid()

tab_control.bind("<ButtonPress-1>", doNothing, True)
tab_control.bind("<ButtonPress-2>", doNothing, True)
tab_control.bind("<ButtonPress-3>", doNothing, True)

status = Label(statusFrame, text = "Status:", bd=1, relief=SUNKEN, anchor=W)
status.pack(fill=X, expand=True)

window.grid_rowconfigure(1, weight=1)
window.grid_columnconfigure(1, weight=1)

window.mainloop()

这是我目前拥有的照片：

Notebook Frame that won't resize

如您所见，“蓝色”部分应填充更多窗口。

谢谢！

Answer 1

只需将height和width传递到笔记本小部件：

tab_control = ttk.Notebook(tabFrame,height=480,width=495)

要缩放标签，请将<Configure>事件绑定到根窗口：

def conf(event):
    tab_control.config(height=window.winfo_height(),width=window.winfo_width()-145)

window.bind("<Configure>",conf)

要解决您的问题，请按以下方式将.grid()更改为.pack(...)：

from tkinter import *
import tkinter.ttk as ttk

window = Tk()
window.geometry("640x480")
window.title("Notebook Test")

options_list = ["one", "two", "three"]

def doNothing(event): # added event argument
    pass

leftFrame = Frame(window)
tabFrame = Frame(window)
statusFrame = Frame(window)

leftFrame.grid(row=0, column=0, sticky="n")
tabFrame.grid(row=0, column=1, sticky="nsew") # changed "nw" to "nsew"
statusFrame.grid(row=2, column=0, columnspan=2, sticky="ew")

Xlabel = Label(leftFrame, text="X Function", anchor=N)
Xlabel.pack()
x_var = StringVar(leftFrame)
x_menu = ttk.Combobox(leftFrame, textvariable=x_var)
x_menu["values"] = options_list
x_menu.current(0)
x_menu.pack()

tab_control = ttk.Notebook(tabFrame)
tab1 = ttk.Frame(tab_control)
tab2 = ttk.Frame(tab_control)
tab_control.add(tab1, text="Default One")
tab_control.add(tab2, text="Default Two")
tab_control.pack(expand=1, fill='both') # changed from grid() to pack()

canvas1 = Canvas(tab1, bg="blue")
canvas2 = Canvas(tab2, bg="green")

canvas1.pack(fill='both', expand=1) # changed from grid() to pack()
canvas2.pack(fill='both', expand=1) # changed from grid() to pack()

tab_control.bind("<ButtonPress-1>", doNothing, True)
tab_control.bind("<ButtonPress-2>", doNothing, True)
tab_control.bind("<ButtonPress-3>", doNothing, True)

status = Label(statusFrame, text = "Status:", bd=1, relief=SUNKEN, anchor=W)
status.pack(fill=X, expand=True)

window.grid_rowconfigure(0, weight=1)  # changed row 1 to 0
window.grid_columnconfigure(1, weight=1)

window.mainloop()

ttk。带有“画布”的“笔记本”选项卡，展开以填充窗口
