删除最小化和最大化按钮后是否可以显示 mytoplevel和window 的图标?root我尝试使用-toolwindow,但之后图标无法显示。有没有另一种方法可以在仍然显示图标的同时从窗口中删除最小和最大尺寸按钮?

from tkinter import *


def top():
    tp = Toplevel()
    tp.geometry("300x300")
    tp.attributes("-toolwindow", 1)
    tp.iconbitmap("My icon.ico")


root = Tk()
root.geometry("400x400")

b = Button(root, text="open window with icon", command=top).pack()

root.mainloop()

特定于 Windows 的解决方案

第一个选择是让你的窗口toplevel瞬态窗口root,这是一个非常简单的解决方案。
您需要做的就是将线路更改tp.attributes("-toolwindow", 1)tp.transient(root)!

第二种选择更复杂,但在 Windows 系统中更通用。
Windows 系统中的每个窗口都有自己的样式,它表示为位样式的逻辑。您可以从头开始构建新样式,也可以将新样式设置为与旧样式分离(将其打开)或将旧样式与位样式的否定结合(将其关闭) :

  • 要关闭最小化/最大化:
    new style = old style AND NOT Maximize AND NOT Minimize
  • 要打开最小化/最大化:
    new style = old style OR Maximize OR Minimize

对于所有这些交互,我们需要ctypes库(python 附带)和一组 WinAPI 函数:

检查这个例子:

import tkinter as tk
import ctypes

#   shortcuts to the WinAPI functionality
set_window_pos = ctypes.windll.user32.SetWindowPos
set_window_long = ctypes.windll.user32.SetWindowLongPtrW
get_window_long = ctypes.windll.user32.GetWindowLongPtrW
get_parent = ctypes.windll.user32.GetParent

#   some of the WinAPI flags
GWL_STYLE = -16

WS_MINIMIZEBOX = 131072
WS_MAXIMIZEBOX = 65536

SWP_NOZORDER = 4
SWP_NOMOVE = 2
SWP_NOSIZE = 1
SWP_FRAMECHANGED = 32


def hide_minimize_maximize(window):
    hwnd = get_parent(window.winfo_id())
    #   getting the old style
    old_style = get_window_long(hwnd, GWL_STYLE)
    #   building the new style (old style AND NOT Maximize AND NOT Minimize)
    new_style = old_style & ~ WS_MAXIMIZEBOX & ~ WS_MINIMIZEBOX
    #   setting new style
    set_window_long(hwnd, GWL_STYLE, new_style)
    #   updating non-client area
    set_window_pos(hwnd, 0, 0, 0, 0, 0, SWP_NOMOVE | SWP_NOSIZE | SWP_NOZORDER | SWP_FRAMECHANGED)


def show_minimize_maximize(window):
    hwnd = get_parent(window.winfo_id())
    #   getting the old style
    old_style = get_window_long(hwnd, GWL_STYLE)
    #   building the new style (old style OR Maximize OR Minimize)
    new_style = old_style | WS_MAXIMIZEBOX | WS_MINIMIZEBOX
    #   setting new style
    set_window_long(hwnd, GWL_STYLE, new_style)
    #   updating non-client area
    set_window_pos(hwnd, 0, 0, 0, 0, 0, SWP_NOMOVE | SWP_NOSIZE | SWP_NOZORDER | SWP_FRAMECHANGED)


def top():
    tp = tk.Toplevel()
    #   tp.geometry('300x300')
    #   tp.iconbitmap('icon.ico')

    hide_minmax = tk.Button(tp, text='hide minimize/maximize', command=lambda: hide_minimize_maximize(tp))
    hide_minmax.pack()

    show_minmax = tk.Button(tp, text='show minimize/maximize', command=lambda: show_minimize_maximize(tp))
    show_minmax.pack()

root = tk.Tk()
root.geometry('400x400')
b = tk.Button(root, text='open window with icon', command=top)
b.pack()

root.mainloop()

我刚遇到这个问题,解决root.resizable(False, False)后发现root.geometry
