[英]How to remove minimize/maximize buttons while preserving the icon?
删除最小化和最大化按钮后,是否可以显示toplevel
和root
窗口的图标? 我尝试使用-toolwindow
但之后无法显示图标。 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()
第一个选项是使您的toplevel
窗口为root
窗口瞬态,这是一个非常简单的解决方案。
您需要做的就是将tp.attributes("-toolwindow", 1)
行更改为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分离。 你可以建立从刮痕或设定新的风格,新的风格脱节的旧有位风格(将其打开),或结合旧了的否定位风格(将其关闭) :
new style = old style AND NOT Maximize AND NOT Minimize
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,发现root.resizable(False, False)
在root.geometry
解决了它之后。
root.protocol("WM_DELETE_WINDOW", False)
