python - 如何使框架无法调整大小

Question

我的框架中有一个“添加任务”按钮，它创建了一个新的文本小部件来输入一些文本，并添加了文本小部件，框架保持垂直扩展

我试过使用 resizable(False, False)，它显示 AttributeError: '_tkinter.tkapp' object has no attribute 'resizable'

class Container(tk.Frame):
    def __init__(self, parent = None, priority = 3, bg = 'bisque'):
        tk.Frame.__init__(self, parent)
        self.f = tk.Frame(parent)
        self.f.configure(bg = bg)
        self.f.pack(fill = 'both', expand = True)
        self.tk.resizable(False, False)

if __name__ == '__main__':
    window = tk.Tk()
    window.geometry('300x200-400+75')
    window.minsize(300, 600)

    p1 = Container(window, priority = 1)
    p2 = Container(window, bg = 'blue', priority = 2)
    p3 = Container(window, bg = 'red', priority = 3)

    window.mainloop()

您不能self.tk.resizable(False, False)用于框架小部件，它仅用于主窗口。

解决方案

如果您只想在将小部件添加到框架时使框架不可调整大小，请使用self.propagate(0)这不会让子小部件接管父小部件的大小。

但是，如果您希望主窗口不调整大小，请使用window.resizable(False, False)

代码

import tkinter as tk

class Container(tk.Frame):
    def __init__(self, parent = None, priority = 3, bg = 'bisque'):
        tk.Frame.__init__(self, parent)
        self.f = tk.Frame(parent)
        self.f.configure(bg = bg)
        self.propagate(0)
        self.f.pack(fill = 'both', expand = True)


if __name__ == '__main__':
    window = tk.Tk()
    window.geometry('300x200+400+75')
    window.minsize(300, 600)

    # Use this if you don't want the main window to be resizable.
    # window.resizable(False, False)

    p1 = Container(window, priority = 1)
    p2 = Container(window, bg = 'blue', priority = 2)
    p3 = Container(window, bg = 'red', priority = 3)

    window.mainloop()
